Hopefully HH does the right thing. What that is right now I'm really not sure.


Update. Horizon is going to do nothing for me. They want me to send it back on my dime and stated that they will charge 1/2 hour minimum at $30 an hour. Sort of answer we Canadians get from American companys in the hobby business. Plane went in the garbage.

I've ordered a hobby king plane and clone Futaba RX so he can fly that with zero issues. And yes with Futaba there really are zero issues. I have thousands of flights in 4 years and not one glitch. For you guys that say you can't say never, well you have never used Futaba then. Sorry but you can keep your 2 channel non-hopping dms2. Funny how the new dmsX has the hopping feature Futaba has used for years.

Radio was from the MSR I won at a fun fly. The heli never gets more then 5 feet from the radio so i guess that's why it works.
Range check was 150 paces with ant. pointed right at the plane, no issue there. When it locked out it was 20 feet in the air, 20 feet out front. Should not have happened but then again do a search for spectrum lock it and you will see a whole lot of " I DON'T KNOW WHAT HAPPENED "

Sorry for my feelings but they are what they are, and it is from 4 years experience.
I read your letter... if I was the person that was in charge of reading and sorting the e/mail then I would have simply deleted it and not even responded not once did you sound genuine, you simply sounded rude.

if you expect service you can't be a bully.

but you didn't expect any service did you... you just wanted to yell at someone.

good luck with the kid, I hope he's more mature than you

I have had a constant problem with the left propeller spinning off shaft. Screeching followed by detachment in mid-air. I would have thought the threading on the shaft was the opposite direction of the motor direction but the prop still comes off. Tried a new prop, same thing even with a tough of CA. Anyone one else frustrated like this?

I have not had any problems in which you describe with many flights with original motors and props. You need to be sure you are tightening in the right direction (which I am sure you know) If you use CA, I don't see how that could come off. I have never heard of this problem

This is the same problem Iv had. your motor is duff! as for the prop spinning off. you just need to manage the throttle in dives ect. to stop it wind milling in flight.

I just had this very problem, after about 55 flights. I lost the prop and have ordered a replacement, so I don't have any "tips" to share yet, but just so you know it's not just you . . .

i put a drop of thread lock on before screwing the prop on. seems to be holding well. and like i said before, throttle management is a good idea too. you need to scrub of speed to stop that prop from wind milling off its shaft.

I'll be honest... I fly at full throttle 90% of my flights (with the exception of the champ which I fly about 60% full) I've had to replace motors on all my ums at least once cause of this and never once have I lost a prop... well one time but it wasn't in flight, had the motor leads plugged in... it sounds to me like some how your propshaft has spun the threading out of the prop and is causing it not to be able to hold any more... I would suggest a new shaft and prop to eliminate all chances of this happening again and like chris said, the loctite sure won't hurt

its because the mosquito runs 1 motor CW and the other CCW. so the right motor is always trying to tighten on the thread whilst the other is loosening. you wont have this problem on single motor aircraft.

Thanks folks for the suggestions. I was not sure if both shafts had the same thread direction even if one motor was spinning the opposite direction. I will say I have been able to control it down to a soft landing even with one propeller on it.

I'm pretty sure the threads are different for each side. If I remember right, they have a different colored back nut or shaft. There is something to distinguish them just can't remember what. At work now, so can't check.

Has anyone converted their Mozzie to run without contra rotating props?

I've not had any problems myself but I can understand why the left blades undo due to the torque on the thread so if it starts playing up on me I'll just fit 2 RH motor setups and see how it flies...
