RE: Bearings size in Himax HC3510
Thanks - that looks like a good place to shop so I'll keep them bookmarked. Just at the moment I've found a local dealer who occasionally imports from Himax, and he'll add some bearings for me to his next order. He too has to pay the huge fixed shipping charge, but every few weeks he does build up enough to order and make the shipping reasonable per item.

RE: Bearings size in Himax HC3510
Thanks for the pointer. The Boca web site looks pretty good and lists loads of motor makers - but not Himax. I'll email Boca and ask the question. Meanwhile if anyone knows where the bearing sizes are to be found, I'd still love to hear about it! PS - I should have mentioned that Himax do sell bearing sets, but their shipping charge to individuals overseas is something I'd like to avoid!

Bearings size in Himax HC3510
Does anyone know what size the bearings are in a Himax HC3510-110 brushless outrunner motor? Mine's making noises like it needs new bearings but I'm having trouble pinning down the size. All help gratefully received :-)

I know you guys are all well invested into your DX radio systems, but I don't have any of the issues you describe with my 2.4 gHz Futaba gear. Independent dual rates are available, and nobody I know with similar gear has ever had unbinding happen. The big downside is the cost of receivers, something like USD100 each, unless you can find a bargain. Happy flying :-) Dave

G'day Mad :-) Our weather is pretty darn good, with some days back to t-shirt and shorts temperature. But we do also get the cool, wet and sometimes stormy days. I was out yesterday morning with some of the guys, and it was too warm to wear a jumper once the sun was well up in the sky. This winter we've only lost three or four weekends model flying to bad weather. So, having moved here from Britain almost four years ago, I just love this country! I've had a look at your web site and the pictures there, and they do give a good idea of what you're describing. Where did you put the servo in the Gunfighter? Cheers, Dave

RE: Parkzone NEW Messerschmitt Bf-109G PNP and BNF
Hi guys - I've put a motor upgrade into my Gunfighter Mustang, I bought it from this guy on eBay who has an equivalent listing for the BF109 - http://cgi.ebay.com/Parkzone-BF-109-Motor-mount-upgrade-Turnigy-3536-/230492511878?cmd=ViewItem&pt=Radio_Control_Parts_Accessories&hash=item35aa6c9e86 It was very easy to fit, all the holes were in the right places and the extra power makes the model a whole lot more fun. I had to shift the battery back a bit to compensate for the heavier motor up front, but it was well worth the investment. And don't forget to upgrade the ESC! You may like to try it on the BF109 to get rid of the problems with the Parkzone motors - all my Turnigy motors have performed properly out of the box, and still do. Cheers, Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
My little dings are all filled with foam, the original foam if I can find it at the crash site (but not necessarily in the original places...), bits of foam from packing that came with other models, or just bits of foam from any old where. After trimming to shape with a sharp knife and a quick dab of paint, they're hardly noticeable. And I think gluing a patch in adds a tiny bit of strength that I might need one day. Good luck and have fun! Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
At a guess, the incidence will be right unless some crash or hard landing damage has caused some free play or misalignment to creep in. I don't feel like I'm being very helpful by saying that it was probably right when it came out of the box ... but that's the best I can do :-) If it looks the same as it did new, it should be right. Do you have a programmable radio? With some of my models I've programmed a mix to couple the elevator to the throttle so that as the throttle increases, the elevator goes down a bit. The amount to be mixed in comes from good ol' trial and error! And it's important to test the effect of the programming on the bench before the model takes to the air - it's easy to make the mix do exactly the opposite of what is wanted. Sorry if that's old hat to you, but better safe than sorry. Good luck! Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
Hi DJH - I wonder if either your motor or wing alignment might be adrift? Mine flew nicely until it didn't.... I discovered the motor mount was damaged so the thrust line was wrong. New mount, new motor, and all is good again. If the wing alignment (angle of incidence, to be technical) is out, that could cause pitch variations at different speeds. I've another high-wing foam model that now has a pile of packing under the trailing edge, required because its rubber bands have deformed the wing, pushed the back end into the fuse and effectively altered the incidence. That one was a pig, shooting for the sky when the throttle was opened, but is now back to how it should be. [quote]I need to use full right elevator during the climb to keep it tracking straight. [/quote] You said you need to use right elevator - is that right rudder, or right aileron? Unless of course you're about to patent a split elevator system [;)] Cheers, Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
Turnigy larger motor now in Gunfighter! In case anyone is interested, I've now got a Turnigy 3536 1300 brushless outrunner (from Hobby City, Hong Kong) installed, sitting on a mount from "books and steam" eBay trader in USA. Installation was a breeze, and to let a bit of breeze through to cool the ESC and battery I've bored a tunnel through the fuse with the trusty soldering iron. The tunnel goes up at an angle from the 'scoop' at the bottom of the cowl to come out below the ESC. Power draw on the bench using a fresh battery showing 12.4 volts was: 9 x 6 APC prop - 41 Amps peak 10 x 5 EMP prop - 41.8 Amps peak 10 x 6 EMP prop - 49.9 Amps peak I'm flying the model with the APC 9 x 6 prop and find it has heaps of thrust for take off and cruises faster than flat-out stock ... at half throttle. Batteries are luke-warm on landing, ESC is stone cold and I guess the motor won't be any hotter than the battery but can't get a finger through the cowl to find out. It does drain the battery though - I'm limiting flights to 8 minutes and getting 1200 - 1400 mA back into a 1600 battery when I charge it. I guess next step will be bigger batteries and some surgery with a knife to fit them in with the hatch on. Cheers everyone - Dave

[quote]ORIGINAL: ADDAX Has anyone else been messing with the CG on the P-51? Thoughts? [/quote] I've just put a big motor up the front of my Gunfighter. Previously the CoG was right on where it should be, as originally stock and after putting in a smaller Turnigy motor than the one that is now in there (see earlier posts if interested). I've had to move the battery back to get the CG near where it ought to be, so the strap now just goes over the battery enough to hold it in place. The balance point now is about a quarter inch in front of the little moulded marks on the wing, so not too bad but the weight of the model has gone up. It flies pretty well, still whips round tight turns, but is inclined to drop onto the ground at landing rather sooner than I'm expecting it to - that could be the stall starting at a higher speed because of the extra weight coupled with the CG being further forward. Or it could just be the pilot needs more practice :-) Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
The Gunfighter flew nicely today in pretty gusty and strong winds, powered by the little Turnigy 2836 / 1200 motor. There's plenty of power, the climb rate is great but the batteries did get hot - much hotter than they did with the stock motor. That's with an APC 9 x 4.5 prop. Next will be to buy a bigger motor, a Turnigy 3536 / 1300, and increase the air flow round the battery as much as I sensibly can. And now that I've started surgery on the Gunfighter, I may decide to alter the battery bay to hold bigger batteries than the Hyperion 1600 mAh/25C ones that I'm currently using. Oh yes, the spinner front spat off and rolled a very long way [:D] as soon as I started the motor for the first launch! A new spinner with cap held by screws will also be in the order.... My order from Hobby King in Hong Kong contains several back-order items so it could be a while before I get the bigger motor installed. Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
The original stock motor has finally been declared beyond repair. I'm putting some photos with this so you can see the cracks in the (IMHO) cheap and nasty plastic plate that forms a structural part of the stock motor in the Gunfighter. I happened to have a Turnigy 2836/1200 brushless outrunner motor on the shelf, which is the same as I have in my hot-rod HobbyZone Super Cub, so decided to try making a mount for it. This job would be much easier if the Turnigy motor mounted at the rear, as the original PZ does, but the mounting screws for the Turnigy are on the front. So I made a mount out of two pieces of light ply and some dowel spacers, stuck together with 6-minute epoxy. Hopefully the photos will show you how it was done. Please excuse the scruffy looking front plate - I pasted my paper drawing to the wood to cut it out and couldn't be bothered to take it off [:)] It's not visible now the cowl is back on. I've pinched the Turnigy Plush 40A ESC from the hot-rod HZS Super Cub to power the motor. A firm push slid it into the slot the stock ESC sits in, and there looks to be enough air flow over it. At least, I hope there is! I know the current draw is going to be way beyond what the 18A stock ESC could deal with. My Wattmeter tells me the peak current draw with three different props, static on the bench, fresh battery and five seconds at full throttle was as follows: [ul] [*] 1. Stock PZ 9 x 6 = 45A [*] 2. APC 9 x 6 = 36A [*] 3. APC 9 x 4.5 = 30A [/ul] I think the motor might be a bit small for this model, as even 30A seems a lot for the small windings in the can to handle. After take-off, I expect most of the flying with this motor to be at half throttle or less, if the Super Cub is anything to go by, so I'm hoping to get away with it. If the motor does go up in smoke, at least it was only $12US! There's enough room to put a bigger motor up the front, and if I were shopping for one, I'd be sure to buy a motor with the mounting plate at the back [;)] With one of my regular 1600mAh batteries in place, the CoG has crept back just a tad, but I don't think it's enough to worry about. The tail is only about 5 degrees off horizontal when the wing is balanced on the CoG marks. We'll see how it goes once the equinoctial gales have settled down and I can get out and fly again [8D] I'll post details of how the test flights went..... Dave

Hi Zsultan - try my earlier posts for info on my batteries: http://www.rcuniverse.com/forum/fb.asp?m=9365167&key= http://www.rcuniverse.com/forum/fb.asp?m=9488757&key= I've got some 2200 batteries in other models but have decided to not use them in the Mustang. I'd need to do quite a bit of surgery on the foam in the battery bay to allow the hatch to close, and probably the CoG would need adjusting too. I think the plane would fly fine with the heavier battery as long as it was delivering enough power (I'd want a 25C rating) but landings would be faster with a possible tendency to tip-stall or drop the nose at a higher speed than I might have anticipated. Hope that helps, Dave

[quote]ORIGINAL: blkz2801 i hit a tree today with my P51. It broke the motor and esc part of the nose cone off. Does anyone have and suggestions on how to repair it? what kind of CA? [/quote] I tried using foam-safe medium CA to repair mine when it piled into the ground. The fuse had split near the front of the hatch, as well as several other bits of damage. All seemed well at first, but the joins failed. I wondered why the model wouldn't flly straight after a couple of flights and found the fuse was no longer straight! The CA seemed to have formed a hard, rough surface along the joint, but hadn't really stuck properly and was steadily letting go. For the next repair I went back to Gorilla Glue, which is sold for woodworking but works well on foam. Gorilla is an expanding adhesive that cures by absorbing moisture from the air, so it takes several hours to set. I usually leave mine to set overnight. The repair will be strong, and on other foam models that I have crashed, the Gorilla bond is stronger than the foam - the next splits occur somewhere other than the first repair! If you use that type of glue, you need to plan ahead a bit and guess where the glue will expand to and contain it with adhesive tape. You will also need to strap up the joint while the glue sets, so that the expanding adhesive doesn't push the surfaces apart but instead expands into the cell structure and gets a good grip. A good tip is to use just enough glue to fill the joint, but not so much that it spills outside and has to be trimmed off (which I find hard) or snapped off (which takes bits of the outside decoration and surface with it). The photo shows the repair - the compression stress marks in the foam from the crash are visible, but it's hard to see the join even close up. Hope that helps, Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
Hi Mad, I'm probably going to be no use at all here ... I've no real idea why the throttle wouldn't work when you wanted it to! Could the battery voltage have got down to the point where the ESC won't feed the motor, but keeps the controls working? I beleive that some ESCs allow a short recovery period before feeding the motor a bit more power, after which there is no more power available for the motor. If you flew the same battery again without a recharge, you'd be able to eliminate that as a possibility. Or do you get radio interference problems out your way? End of 'wisdom' [:o]

Hi Chetterb - you may have picked up from other posts that I'm using Hyperion 1600 mAh 25C batteries, and find them pretty good. I've sort of worked out that if I fly ten minutes or just over, the re-charge time is going to be between 35 and 50 minutes, but if I fly as much as twelve minutes, I'm going to spend anything up to an hour and a quarter waiting for the battery to be full again. So I've decided to keep flights down to around eight to ten minutes, and get twice as many flights in a session. Works for me, and of course, your mileage may differ [;)] Enjoy the good weather! Dave

G'day Mad, and it is a beaut day here. Temp is nudging 30C, the sky is blue, the breeze is coming in off the South Pacific ... but then it is mid summer :-) I had the Gunfighter out this morning and really enjoyed it, going through seven battery charges. I'm slowly getting the hang of inverted flying, but only when there's plenty of height in the bank! Your idea to block off the bottom scoop sounds good, but you'll surely make the first flight a short gentle one, and check that the battery and speed controller aren't getting too hot? Now that our temperatures are up, I'm finding the batteries are getting warmer than they did in spring, but I am also probably flying it a bit harder than I was. When launching, I'm finding that I can sort of feel when the wind over my face will be enough to produce lift from the wing and control from the ailerons. I don't run any more after that, and it's usually only two steps when there's a bit of a breeze. In a stronger wind I don't run at all, as the model is eager to fly without it, just a gentle throw at the correct angle is all that's needed. It's all a bit hard to describe as it's more a feeling than anything scientific, except maybe the model does feel a little lighter in the hand and ready to go up. I've finally remembered to post a picture of my hand holding the model at the launch angle, ready for flight. Did I mention my hands are very small, so I can't grip anything much further apart than shown in the photo? Enjoy some good weather when you get it [8D] Dave

RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
OK - I answered my own question. When I had re-assembled the parts of the cowl, I could see that the motor shaft was not in the centre any more. I took all the motor mountings apart and discovered that the mounting plate at the back of the motor is a plastic moulding, which had a couple of cracks in it, allowing the motor to point off line. The motor shaft itself appears straight and spins freely. I've dribbled a little bit of CA into the cracks, hit it with kicker and hope the seepage onto the part of the motor that is static will hold everything straight. If not, I reckon it'll be time for a motor and ESC upgrade. The firewall and matching nylon (?) mounting plate (which screws to the repaired motor plate) both seemed to be fine after the crash. Now I just need the new prop and spinner to arrive and we'll be flying again!! Cheers, Dave

It's the first time I've had the cowl off, and I see that the motor can and shaft are not perpendicular to the face of the motor mount. I hope the picture will make clear what I'm seeing - the picture is looking down vertically on the front of the model. The motor shaft is more or less in line with the fuselage, and does not have the side thrust I would have expected. Thanks for any help! Dave
