RE: Nitro models pusher Bobcat?
Glad to see the electric conversions are working. When the larger "kee kat" arrives I plan on powering it with an outrunner of some sort. I would be interested in hearing some more details of your setup.

RE: Nitro models pusher Bobcat?
I have been speaking with a vendor who is supposed to be getting the larger "kee cat". It seems to still be a few weeks off. I am hoping it will not be too difficult to electrify and will not be much/if any heavier than the glass version.

RE: Nitro models pusher Bobcat?
The "ling cat" is 32" wingspan. I got it at www.ejf.com I have toyed with the idea of robart 1/2A retracts but if you use all the servo location provided that comes to between 6 and 7 servos. The plane is amazingly light and would work really well as a pusher or EDF. The larger version with the retracts is not available....yet.

RE: Nitro models pusher Bobcat?
I have the "ling cat" from avia-richmodel. It is extremely light weight as the bare airframe weighs about 12 oz. I am wanting the larger kee cat and have spoke with a vendor that is trying to get some in. Initial report was they are not set up for retracts despite the photos but then I was informed a while later that they were built with retracts. The specs are fairly similar between the avia-richmodel and nitroplanes as far as dimensions go. I am hoping the avia version comes out lighter than the listed weight as there is a 2 pound difference between the two. I never realized the nitro version had a glass fuse. Knowing how heavy chinese glass work is I am hoping the weights will be fairly close between the two. The AUW for the ling cat was 26 oz. on their site but I could easily see it coming in at 22 oz. or less without too much work so hopefully their other weight predictions prove to be a bit overstated as well. I would love to see some photos of this version after completion as well!

RE: Plane for an E Flight Park 480 motor?
The fliton planes are really built too light for this motor. I installed one in the fliton extra but never flew it before going back to a smaller motor. It was probably a good thing as the motor would rip the motor cage apart. It is a real powerhouse with an 11x7 or 12x6 prop. I have to say I was really surprised as I have the equivalent size AXI's and Hackers and I do not think they can compare for thrust (they are higher KV too). I think this motor would fly the EF extra if you could get it to balance. It is a bit lighter than the recommended setup and you could make about 280-300 watts with a 2100 pro-lite. I have flown it in a mini katana at about 28 oz. and it is plenty strong with hovering at 1/2 throttle. I just installed it in a Brio. Of the planes you listed, only the BME, EF, and HYP Yak would be immediately suitable. I have the HYP yak and extra and the extra is built really light and the motor is too big for the motor cage. The Yak 55 would work with an 11" prop. It is a beutiful plane. I have no experience with the BME yak

RE: Mini Bipes
Make sure you fly the plane off a smooth surface. I just got mine going a week ago and flew it off a relatively smooth gravel/dirt road. The plane is hard to steer on the ground because of the short fuse. I basically line it up and gun it with a helping of back stick until it lifts off. Be prepared to get off the up though as I have almost stalled it twice "yanking it off the ground" this way. It would be much better I am sure off a paved surface. The stock motor mount is really weak and the glue joints are poor as it seems you have found out. I went brushless with a geared himax and lipos and basically built a reinforced stick mount off the firewall. I took out the rear fuse former under the cockpit, moved the servos as far forward while still allowing me to reach them, used CF pushods and lighter hardware throughout. The plane flys pretty well now though the plastic cowling is really weak. I broke both the wing struts off as they did no align well with the wing and made replacements with 1/32" ply with a piece of wire to reinforce it. I am using wheel collars to anchor the screws through the lower wing which allows for removal quickly. I usually leave the wings on and take the cowl/prop off to unplug the battery. I routed the ESC/battery leads through a handful of holes I cut in the firewall to lose some weight. Will try to get some pics to illustrate here shortly.

RE: New Watt-age Pitts
If anyone has one in their possession and could provide some pics of the fuse and wings it would be appreciated. I have the old version as stated and am wondering whether the newer one would be worth upgrading too. I finally flew mine last weekend and am really pleased. With lipos and brushless it weighs alot less and actually slows down pretty easily and is easy to land. I assume the fuse is still plastic? I do not think you could drive four ailerons with one servo like the stock setup so if I mod mine I may have to put a servo in each wing. Lastly, what color is the wing? I remember mine coming covered in red and white with the blue decals to be added. If the new wing looks the same except with four ailerons I could purchase it and just add the blue to make it match the lower.

RE: New Watt-age Pitts
Is the new pitts going to be the same as the old one except with a different wing on top? I just bought the old one when it was on sale and it is ok and I have not flown it but I would really like the dual aileron setup. I wish they would make it in the traditional red/white scheme also. I am going brushless with a geared 2025-5300 or a typhoon 15/10 and 3s lipos hoping I can get it to balance.

Slope conversion power questions....
I have an foam f-16 slope soarer that I am debating on converting to a pusher or EDF. I live in a flat area and really have no way of launching it except by hi-start. The plane is under construction right now so I have some options available still. I have a GWS A-10 and the performance is "OK" but I would really like something faster. The F-16 has a flat bottom airfoil with a wing area of about 210 sq. in. and about a 30" span. I do not know of the flying weight but will be using two micros, a standard receiver, and possibly lithium batteries. I am guessing it should weigh less than the a-10 somewhere in the 10-15 oz. range. The fuselage is about 2" wide and 4" tall in the midsection so I think adding a fan would be fairily challenging while keeping it somewhat f-16 "ish" looking. I would have to build a shroud around the fan and blend it into the fuse as it is too narrow right now for all but the smallest GWS fans. I was thinking of putting a speed 300-400 motor on the back in a pusher config. much like the wattage F-22. Again the fuse is fairly narrow so something small but fairly powerful would be advantageous. Which route do you think would be most successful as far as performance is concerned. I really like ducted fans but fear the construction would be more challenging and the performance might not be as good as a simple pusher setup. Lastly, if I was to go with a 300/380/400 size motor, what type of lithium setup would work out best. Do you "have" to buy the expensive chargers for lithiums or will the converted cell phone chargers everyone is peddling work ok? Any ideas or opinions? Thanks!

Hobbico free flight EDF conversion....
I have seen an ad in a magazine by greatplanes/electrifly advertising a conversion kit for many of the hobbico free flight airplanes including the EDF models. These models use one of the quick chargers that charge the batteries on board in about a minute that you plug into the bottom. Somehow they are saying you can convert them to R/C. The ad just mainly shows some micro servos and equipment but really does not say much about the actual conversion. I think this would be a neat thing to try if you could get it to work as these planes are really cheap. I would want to find a way to do discard the quick charge method of course and convert the motor system to onboard to extend the flight times. These things look like they would be fairly heavy set up for R/C and I do not know how fast they go configured as FF. Does anyone have any ideas or experience doing anything like this. I assume it might be similar to the flying styro f-16 conversion in a way. Thanks

RE: Electric Ace Simple Extra 230...
The guy I bought the battery from says it is at least 700 mah but could possibly be up to 1000 mah, that some were charging that high. I would not guess that the plane is necessarily light. I built according to the plans. I have no way to weigh it right now unfortunately. I thought about getting the GWS 480 ESC. Do you think the geared 300 would have enough power to lug it around? What would a speed 400/480 require as far as batteries go. Thanks for the input!

Electric Ace Simple Extra 230...
Hi, I am new to this site and have been fiddling with R/C for about 8 years off and on. I have built a Simple Extra and have never flown it. It currently has a cox .049 on it but I am really wanting to convert it to electric as the engine is old may need work as it has not been run in a really long time. I will be using 2 micro servos, 1 mini servo and a standard size 4ch. receiver. What combination of motor/prop/battery would I need to get good performance. I am not interested in unlimited vertical or serious aerobatics but would just like to get it in the air and do the occassional loop and roll. I was thinking about a speed 400 or 480 but was not sure this would work. I have a 7 cell 8.4 nimh pack I would like to use but might be switching to the lithium cells in the future. Also I have a GWS ICS-300 but am not sure if this would be enough to handle the current to the motor. Any help or ideas would be GREATLY appreciated!
