HBFP Tail motor problem...

Hey guys, i am currently experiencing a problem with my stock tail motor,

It revs really highly(maybe full) even with the slightest amount of throttle, which send the heli into a spin, even before the main rotor motor even starts, and while trying to get it in the air, throws itself to the left and right, completely uncontrolabe, so uncontrollable that I cant even workout if I need to adjust anything!

It went from flying fine, to this with in a battery change.

Any Ideas???

I have never had to replace the tail motor, so am unsure at what it does when its done its dash, I figured it would just stop working?????

Please help!

Sounds like it could be the tail motor. It won't quit working all of a sudden, just start misbehaving sort of the way you described. Before you change it though, look at the mesh between the tail motor pinion and the gear and be sure the gear isn't slipping off to the side of the pinion. I made a post about this a while back, but I can't find it.

sounds like the tail motor to me

Cool, thanks, I will look into it!

As a matter of fact, it was soon after I smashed the tail into the wall, and then a battery change.

So I hope i havnt wrecked the esc in my 4 in 1 for the tail!

Il see what happens, I will grab my mates 4 in 1 to test the motor, I will check the mesh before doing that though.

Bummer, looks like the 4 in 1 has packed it in.


I tryed me mates receiver on my heli, and worked fine, I must have wrecked the esc for the tail motor, un-fixable!!!

New receiver time, or a good excuse to get the FP V2!!!

THe FPV2 looks to use the sam 4 in 1 as my 2.4 honeybee, and the sell it with the 11.1v lipo.... interesting, as Ive always been to scared to try a 11.1v.

Il probably get a new receiver aswell, as I cant bare to see my un-usable heli! May as well keep this one in the air, and have the V2 to!

You can open 4in1 and look for burned fets. If you see something burned out replace it (if you have any soldering skills of course) It is easy to solder And you can find needed parts in radio shack shop
