His post have been very intelligent, in fact more intelligent that some of the other posters here claiming support for a company that is known for deceptive trade practices, shipping irregularities, poor to none customer service and advertising for illegal commerce activities (shilling). For a company that doing 1000s of orders per day, as reported by some shills, which evidently was false information. Hobby King wouldn't be advertising for shills . A company that is reaching for straws to survive would employee such under handed and unethical behavior. Hobby King may be in bigger trouble than we know. As for store fronts in the U.S. I don't think so. Even the so called U.S. warehouse is just a UPS mail drop. That's been reported as fact by person or persons that have actually gone to the address of the "Hobby King U.S.A." warehouse. But it's good to know that some of you are such important people, above all else, and privledged that Hobby King gives you preferable treatment. It must be really nice that you are so important that a big company like Hobby King bows down to YOU and provides you with the RED CARPET TREATMENT. WHAT IS IT THAT YOU DO TO DESERVE SUCH TREATMENT? Oh I see, you do as you have in this thread. Bash everyone that has a complaint against Hobby Krap, and puff up your egomania that you have never had a problem with Hobby King. Fast Shipping????? Where in the h_ll did you dig that up. We all know it takes a week just to get an order from the FRONT warehouse to the REAR warehouse. Another week to provide a shipping label, and then it sits in the corner until someone puts it on a truck to go to the carrier. And heaven help you if just ONE of the items you ordered is BACK ORDERED. Hobby King holds the entire order until the ONE item returns to stock. I have heard that can take MONTHS.

I even use two HXT900s in an Evader... 22 flights and counting... foam jets like the Rebel, Stinger, and others, 100+ flights and counting... motors, never an issue at all... shipping from Washington for batteries, 3-4 days, (click "priority", $13), planes take about a week, In my opinion, Ladies and Gentle these are the classic statements of a shill plain and simple.

RE: JetJoe OWNERS thread
Steve, Is there any drag in the motor bearings at all? It sounds like the motor is running fine which is a good thing. Did you try a new Joe starter or other? Any speed 300 motor will fit. I have tried a lot of different motors but unfortunately they come and go so if you find any that work, buy 2. Here are a couple below. The first one is an 8 dollar motor off tower. It looks identical to the jet joe motor and does work. The second one is a much beefier motor but I do not know if it will deliver the RPMs needed. The difference is the 7.2 volts versus 6.0 but I would try this if I had it to try. Both have the spleened shaft you want for the securing the bendix clutch to. This motor I have in one of my turbines: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXGLK3&P=7 Here is another that may work... The dimensions are right but I have not tried this one and no upper RPM posted. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXAHK6&P=7 Let me know how this works. If you want to use a JetJoe starter, I will have these in next week. Andy JetJoe Authorized Dealer and Service www.crxdesigns.com [quote]ORIGINAL: meps Hi Andy, I got it to start using air.

RE: JetJoe OWNERS thread
Steve, You have too many variables going on here. You need to make sure you have a good pump and if you are using a starter, you have to have a known to be good starter. Obviously make sure your batteries are fully charged. Flightworks pump for JJ is fine. Lower the pump start point. There are some other things to tweak but I do not have the parameters in front of me. The pump being bad will cause idle to go all over the map. The ECU figures out how to get back to idle by recording the electrical current applied. if you have a bad pump, the ECU goes back to the current value it has stored and has no idea what the RPM is/was. If your pump is not in good shape, the current needed to make the engine idle might be lower or higher from the last known value. So your idle winds up all over and probably won't drop down from 60 k or so. The starter being bad if it does not spool up in proper response to the ECU will definitely cause your engine to over heat fast because the pump is cranking fuel but your motor is not spinning up fast enough in response. Your best bet (assuming you have the pump issue resolved) is to air start the engine with compressed air. The starter on these motors is a bit of an Achilles heel to start so when you are working with other possible issues leave the starter out of the mix and I always go for air start. Once all the bugs are ironed out, then I try it with the starter. There are just too many other potential issues to let a starter become an issue. Fix the pump issue, try to air start the unit and after it is running look at the temps as the motor increases thrust. If the temp is too high but reaches full RPM, you may be able to get away with trimming the exhaust cone little by little to get the temps down. If the engine does not reach full RPM and you are overheating, then there is probably something else going on but try the obvious stuff first. Andy [quote]ORIGINAL: meps I'm still trying to get my engine to start reliably. The original starter quit working so I replaced it with a motor I had lying around. After blowing several glow plugs, I turned the voltage down. I got it to run only after using my blower to help spool the engine after the start sequence was initiated as the motor does not seem to have enough power to do it on its own. The original motor wouldn't spool it up either although the battery was freshly charged. After it started running, the temps at full throttle ran around 750 degrees celcius. The idle is very inconsistent. It ranges from 43,000 to 67,000. Can someone with a smooth running engine post your parameters and give me some insight as to how to make my engine run good? Thanks, Steve [/quote]

RE: JetJoe OWNERS thread
If that thing is spinning full RPM and there is a red glo at dusk or minimal lighting, this is normal. Temps at 600 and change are low. Your motor will produce optimal thrust at 700 or so but lower temps help preserve the motor. The 3000 puts out some decent thrust so keep the low temps. The only thing that will change the temps here is the nozzle opening, meaning a lot of people have to mill down the exhaust cone to provide more flow and lower temps when temps are too high. If the motor ever reached 890, you'd probably start seeing pieces of metal coming out of the motor as the NGV starts to breakdown but I have never tested that theory. 600 is nice. Andy [quote]ORIGINAL: Dr Honda Hi all, I helped Blake run that JJ-3000, and the Max temp on the ECU was set at 890 c !!! I put it down to 780c before the first run. But yes... it runs cool. I think we saw 730c as it was starting, but when it got to idle... it was right around 600. The engine seems to run fine up to 85~90% power. But, at full power... the nozzle starts to glow. Is it normal for the 3000 to glow at full noise? [/quote]

They are loud yes. 800 is standard temp limit. Don't use 600. This value does not control the engine, it triggers a shutdown if the value you enter is exceeded. My engines run 620 - 650 normally. 800 is what should be in there. 780 is fine as I would not want to be running the thing consistently at 780 or above either. It is only an absolute limit.

RE: ARF's ruined my hobby
I have built and flown more kits and scratch built planes than I can count and have had many ARFs as well as foamies. I have generally found that the ARFs seem to come apart more readily than any plane I have built from kit or from scratch. There are a lot of quality levels for ARFs so it also comes down to the quality of the ARF you choose to purchase... I find that I do not have as much respect for an ARF, There is no skin in the game with an ARF. This has zero to do with the cost. I find that if I build a kit or scratch build from plans and I like the way the finished plane flies the thing somehow becomes a gem. As for how they look... I've rarely seen a plane after a year of flying that did not look like it needed a face lift. As for coverings... Monokote and other films I find that all of these films peel off everything over time regardless of how they are applied. Having flown a fairly equal number of ARFs and kits, I also think this really comes down to people who like to build and fly and those that just like to fly and have little desire to build... [quote]ORIGINAL: dirtybird ARF's ruined my hobby. I used to enjoy building and flying RC aircraft and taking them to and showing them off at a fly in. Currently I cannot build an aircraft as precisely as the jig built Chinese ARF's with professionally applied covering without spending an enormous amount of time. Then I am reluctant to fly it. The fly ins I used to attend have either been taken over by youngsters flying 3D or have disappeared. To top it off 3D flying looks to me like someone tossed a cat up in the air - not like an airplane flies. I have no desire to do it even if I could. I need a new hobby. [/quote]

RE: What is a good engine for a Tower Kaos?
Avistar is a top wing trainer. Assuming you are very comfortable with the Avistar then you could try the Caos but maybe with a 40 sized motor (.46) or Super Tigre .51. The caos was a design of Joe Bridy who long since sold rights to his designs. I am pretty sure this is 90% the same plane that it was. I have a 60 sized version and it tweighs all of 5 pounds. I put a ST 90 on this and it basically drills holes in the sky. It is a comfortable flier that flies like it on rails and will take on as much power as you throw at it. Assuming you do not demolish it, you will probably wind up keeping this plane around for a long time. The .51 Super Tigre or even the OS .60 would be plenty powerful but again you might want to start with the smaller motor first. Andy [quote]ORIGINAL: Alex4690 Hey all, I think i've pretty much made up my mind on upgrading from my Avistar 40 to a Tower Kaos ARF.

RE: Question about Giant Jets Inc F16 Plans
The model says 38 pounds max. I assume this is based on using a ducted fan. At 38 pounds with 10225 square inches wing area, this is less than 9oz/ft wing load. At 64 pounds it is 18 oz/ft wing load and for the model as it was presented in the article at 17 pounds wing load is less than 3oz/ft. I do believe that this is the same model as the article given the blueprints have the same notations on them as the article print out. I have a 30lb motor that I could use it for this build. I have been on a fence about building this because it is a lot of time to invest building a plane without knowing if it is going to be what I want. I see plenty of companies that still sell ducted fan kits out there that are adapted for turbines but is this really the same as a plane that was originally designed for a turbine? What is the typical wing load on other F16 ARF/kits out there today? Andy [quote]ORIGINAL: Ram-bro by chance are these even the same model? I believe this model was setup for a byron fan unit, a very draggy/ unclean setup to start with. Ducting cleans things up and attention to detail. I imagine with a D/F unit it flew like a kite at that wingloading. This build judt tells me you can beef up as necessary, detail as necessary and the additional weight and power will be a positive.

RE: Question about Giant Jets Inc F16 Plans
I had a look at the article. How does this model compare with other newer builds? The wing loading being as low as it is was probably done to accomodate a ducted fan. With wing loading so low, it seems to me that this thing will be slow moving due to drag. Bigger motor might be a waste... Probably stick with a 20#. Any thoughts on this?

RE: Servo Extension Soldering Technique
I have been in Engineering for about as long and flown for longer than I can remember. I had one of my first planes hit the dirt from a crummy connector and swore never to use another extension ever again. I cut every servo lead 3" - 5" from the servo and spice in a length of servo wire needed for the entire run then take the female end snipped and solder it to the end of the wire going to the RX. I have used lap joints and twisted joints and always use shrink wrap as described. I have not had one failure in the countless times I have used either of these methods. And, the cost of two extensions is more than the cost of 10 feet of servo wire. The only place I find you can not get around an extension is for aileron and retract connections in planes where the wing is removed for transport. As for wicking, if you are fast with your soldering you should not have any wicking and if you do break any wire then perhaps secure the full length of the wire to the surface you are running along so it remains rigidly secured. [quote]ORIGINAL: Whizbang I agree strongly with DB. Soldered joints in extensions are a very bad idea. The wire WILL eventually break where the solder stopped wicking up the wire. Leave the servo lead and connector alone. Buy a quality crimper, wire and connectors and make your own extensions or, buy quality commercial extensions. You might get away with soldering leads for a while, but I guarantee it will eventually bite you. When it does, your loss will have more than paid the cost of doing it right. I have been working in the electronics field for 30 years and flying models for 40. I've seen a lot of different failure mechanisms and the broken wire at the end of a solder connection is close to the top of the list. I don't want to sound like an arrogant know-it-all. I'm not. I just have a lot of experience in this area and I want you to be successful. Bryan [/quote]

RE: JetJoe OWNERS thread
Hi, Assuming your motor is fresh and known to be in good shape you will want to run the motor and note the temp along the thrust curve. You want the temp at full bore in the low to mid 600's max. I have been told that the motors put out the best power at ~ 720 or so but your NGV is not going to last if you run at that high temp. Carefully mill down or cut the cone in small increments until the temps are acceptable. Also make sure to run a dremel along the inside of the cone each time you cut as any burrs can affect the temps as well. You can converge your exhaust tube but your temps start to go up again. Widening the cone lowers thrust. Converged pipe (big to small at opening) raises thrust but also raises temps. Be carfeful when you play with this and watch your temps. My feeling is that it is better to sacrifice some power and have a healthier running motor that will last longer. I am sure most will agree that over temp is your worst enemy on these motors. Andy [quote]ORIGINAL: jymster It may have been posted here already, and probably in another forum somewhere, but what effect does modifying the exhaust cone have on thrust and exhaust temp?

RE: JetJoe OWNERS thread
Leighton, I did not realize that your motor is so young. I thought you had some miles on this. I highly doubt there is anything wrong with either of your bearings with minimal time on them. I don't even know about gummed up O-rings as this tends to happen with more hours but who knows. Hearing that you have minimal time on this motor leads me to think this cooldown issue might be something more simple than preload or anything else we have been discussing. I did not have the issue with the JJ ECU then it started somewhere after I changed to the Xicoy ECU. You might want to ask Gaspar about this since it sounds like you just bought the ECU or I can run it by him as I purchased one from him recently and had the same issue. I would be curious to hear if there is a simple electronic fix to this. Andy [quote]ORIGINAL: OzJetBoy I built the JJ-1400 from kit which is a larger one A great excercise that I thoroughly enjoyed!

To have the engine start first time what absolutley a blast - a day Ill never forget - grins from ear to ear. Ive done a couple of runs - always having a problem with the cooldown cycle and they guys on here have been helping me to sort out. Ended up burning up a Thermocouple sensor so that ends the fun until a replacement arrives. Glad to hear the youll be ok at Grays Point Do you know if the JJR is comparible to the JetCat P20SE?? [quote]ORIGINAL: jymster Hi OzJetBoy, thanks for the friendly welcome. I actually live in Grays Point, in the Sutherland Shire. Not really any noise restrictions there. I work in Glebe. Which turbine did you build from a kit? The Junior, or a larger one? [/quote] [/quote]

RE: JetJoe OWNERS thread
So you punch the tunnel or the bearing race? [quote]ORIGINAL: frema are you shore it was at the bearing outer ring? i always punch the seat where the bearing slides in . In the shaft tunnel just below the oring groove. maybe there are more people with tricks then [/quote]

RE: JetJoe OWNERS thread
I knew I read it somewhere.... How do you grab the bearing to punch the outside of the race? I take it that the punh has to be below or above the area where the Oring groove is. Andy [quote]ORIGINAL: frema Martin... Question for you ... if you spin the turbine by hand, how long does it continue to spin for? I think 5 or 6 turns , not inmediatly stop , then there is something wrong. [/quote]
