Just be careful with the tail motors. You will still have to stop and cool off every four minutes, or you may have to change tail motors after every flight. Just that you may not have to charge as often.
Cheers

Status: offline 		hfenn, been thru alot of tail rotors myself, I always keep spares handy.. Nice job on the landing.. my biggest fear is losing the tail at altitude and watching it crash to the ground.. Both times mine were like yours and died just at the ground.. been kind of lucky like that..
Mwcyborg, I saw that technology on a show a few months back, sounds interesting, but time will tell how well it works and how much it costs.. I would like to see a price drop in the batteries first, thats the big issue right now..

Status: offline 		Finally got my 22E back into flying shape last night.. had a few bearings that had to be replaced, and the guide pins had to be glued with epoxy.. seems this head with only 2 flights on it wasn't such a good deal after all.. the head is fine, but the bearings are junk.. Had to "Borrow" a few 3x6 bearings from my sons x-mod to replace some bad ones and the new bearings in the blade grips were all bad.. they were very jerky in their movements.. tested in the shop and adjusted the tracking.. There is no vibration at all now.. everything is silky smooth like a new bird.. I will fly a few packs tonight or tomorrow.. wanted to fly this morning, but I had to put my sons x-mod back together before work...LOL
I have the day off tomorrow and according to the weather report, should be sunny and very light winds... maybe I'll burn up a few packs and my son will as well..

Status: offline 		cenracer1 I was about 10' up with some forward motion, but it still wasn't as bad as it could have been. Well, I spent the afternoon finding out that the E-sky 3-in1 is not suited for the 22E (gyro doesn't have enough gain and the proportional mix maxed out and still not enough), so now I've put the stock radio back in and borrowed the tail motor from the HoneyBee for the time being. Now I know, and knowing is half the battle (now I'm quoting GI Joe, lol).

Status: offline 		Flew the new and improved..LOL 22E this evening and it went perfectly.. the heli was super smooth with no vibrations at all.. not even a hint.. The tail was rock steady as well.. I have never had it so steady before.. trimmed out center on the adjustments and it held for 3/4 of the pack.. then 1 click to the right for the rest of the pack... I usually don't do this but I flew in a parking lot behind my condo, so was a little more nervous about landing than normal... everything went too well... I hope tomorrow is just as good as tonight was....
Hfenn.. I thought you were closer to the ground than you were...that just makes your landing even better than before...

Status: offline 		Hey Guys I have a Q about tail motors. I've never had one seize up during flight. I've always been lucky enough to pick up the symptoms of a dying motor and change it before disaster happens. This has been the same for my main motors aswell. From what I've read on earlier posts it sounds like a tail motor can just lock up during flight? I can image how scary a pirouette landing could be...??
Has anybody had a main motor or tail motor lock (die) up during flight? I would love to know how it went???

Status: offline 		mwcyborg....um yeh, I've had the main motor go way up high but all my tail motors have died slowly in flight forcing me to land with the rudder hard to one side to drain the last bit of life out of the motor for a safe landing.


Because the main motor is bigger than the smaller one, the brushes inside it will give way slower during that minute in which the heli dies. As the brush parts melt away or lose contact, the heli starts to drop as the rev's die down....I gunned the thottle to full and the heli came down to earth quite gently. Then, once on the ground I dropped the thottle back to 50% or so and watched as the motor slowly died completely. Blades came to a stand still and that was it basically. At the time when it happened I thought I had killed a battery - but I later found it was the motor.

Thankfully I havent had a motor completely fail catastrophically!!

I'll have to learn how to auto(rotate) the Belt CP before the motor dies on it - although I suspect that the motor in it will last for many hours.

Status: offline 		Hi Tom

Thanks a lot for this info. It is a little reassuring to know that most of the time the motors show a signs of ware, and shouldnt suddenly die during flight. One of my many Honeybee CP2 tail motors that I replaced had actually locked up where it could not be rotated even by hand, luckily enough this was only after I had landed. I have not had a problem like that since I've been using heat sinks, and I recon that its benficial to use more than one heat sink on both the main and tail motor. I guess excessive heat is what seized it.
