Walkera 22e tail motor upgrade - 7/5/2006 4:21:49 AM

I've read many posts about the tail motors frying easily on the 22e and so did mine, after only 10 startups, with only the stock NIMH battery and no more crack-ups, crashes or other malfunctions (so far). This question may have been answered already in this forum, but I can't find it, so again is anyone using a better tail rotor motor for these things-I seem to remember someone posting about soldering a resistor in series in the voltage supply wire to drop the voltage, but I think this was only fro using lipos. Is there a brushless tail motor that can be popped in the 22e? I'm using the stock Walkera receiver and brushed motor for the main rotors-after changing the blade pitch and charging the NIMH through a few cycles it has plenty of power to get off the ground. Thanks.

Could you be more specific? I know these are made by Johnson motors. But I would like to hear from someone who has fitted something better than the stock replacement tail motor-I'm sure there must be something more durable as I don't trust these at all, even with a heatsink. If someone can direct me to another post if this has already been discussed, thanks.

why don you try the direct drive tail motor for the GWS.. it comes with the blades and the longer tail motor.. it last longer than the stock and is more responsive...

Have to tried looking into a twin tail motor upgrade? Supposedly this reduces the workload of the one motor and splits it to the second. There is one at this page http://www.helihobby.com/html/dragon_fly_upgrades.html but I don't know the fit.

I'll looking to see what I find out

the twin system looks good. but still with the small motors like that it has a real tendency to burn up... its the design of this small motors that the problem.. well it is not really design to go on continues workload with all that power so it just heats up and burns the gold fingers it uses as connection.. better to make very small brushless motors to eliminate the small gold finger brush it uses

The GWS setup-might be better for me (fewer parts to lose or break!) I had a hunch this might work. It certainly would avoid losing more tail rotor parts. I will install the GWS on 2 Walkeras if it works, I'll let you know-could replace the Walkera #4 and the 22e tail motors which by the way with this forum's help, I now have both airborne! It took alot to set up the 22e. The 22e CG is inherently tail-heavy-the true CG on mine without battery is just behind the main shaft. By putting the stock NIMH vertically instead of horizontally, it helped balance it better, but still needed some weight in the nose-that was my biggest problem! And better hardware in the head to replace broken linkages, but that is another thread, sorry. But man, can this baby fly when it's set up right-really nice. Thanks again much for the advice, I appreciate it.

Are you running a heat sink? This, and not letting the tail motor trying to run while stalled, are probably the most important part of tail motor longevity.

OK, will do. I will post it only if I'm certain the part is working without damaging anything else. I am using a store-bought heat sink, and experimenting around with home-made stuff. I just broke apart the old burned-out tail motor-wow not much left in there-busted-up wires and pieces of metal-not much to it. I'm still confused about TX dip switch #6-tail C. What's the difference between on-off here? I know factory default is off, but does it matter-I'm guessing off varies with the mixer/receiver and on controls it with the throttle?

That's what I needed to know-the Walkera posts actually had a link back to the RCUniverse forum which answered my question about how #4, 5 and 6 DIP switches are used-and cleared up my confusion about the #7 ccpm/normal switch also. The 22e is a collective pitch copter, but its servos are not set up as other collective pitch copters would be, thus #7 should be off-talk about confusing. And this post claimed some of his DIP switches are labelled backwards! I guess I'll have to experiment to see, but I have a better understanding and have to do some more studying and practicing. Thanks Krisma.

I used the EDF-40 Ducted fan on my Honey Bee and I love it! I hope it last a while, I plan on using the EDF-40H on my 22E after a few flights with the o.e.m setup. Motors come with heatsinks and the units are pretty inexpensive. See this post for pics of the mod....>>> http://www.rcuniverse.com/forum/m_4530551/tm.htm

Very nice-how did you cut the tailpiece, is this balsawood or something else? Some other very nice upgrades-the landing gear looks pretty cool-some of the other aluminum parts are a little expensive, but the tail rotor options aren't. I just ordered the high authority tail motor from another vendor-I think I'll try that with a direct drive prop first-maybe I'll put that one on the Walkera #4 and the ducted fan on the 22e.

high authority tail motor??? is that what it's called?

and with that in mind I need your help people:

I finally lost my tail motor but it didn't burn out, it crashed out... tail rotor hit something and I think caused the motor to fall apart internally.

what I need to know are the specs of the tail motor.. size, voltage (regulated by the resistor i assume). I can use this info to buy my new motor and post on my parts list thread
