My first Piroflip! shame it was not on purpose!!

[gazmk2]

Hey guys,

I was out flying this afternoon ad had my Gaui 425 out, all going well until I tried a backflip and the tail just completely went! I actually ended up basically doing a piroflip as the heli finished up point the same was I started!

I'm using a 3gx with version 3.summat, is the tail blowing out a common issue on the 3gx? if so would a firmware update to 4 or whatever it's now up to sort it?

The heli is otherwise performing very well with the exception of a tendency to want to tip over if you don't punch it off the floor!

Cheers


Gary

Hey buddy.

Sorry to hear you had a brown trouser moment :-/

Off the top of my head I canmot remember 100% if the 3GX had collective pitch tail pre-compensation in V3 firmware. I think it does and to function properly you have to tell the 3GX which way up it is mounted. If this is wrongly set as collective pitch is added any tail command given by the 3GX to counteract the torque reaction on the fuselage will be wrong and make the tail swing round even more.

When I am on my pc I will check if V3 had this parameter, but if it did this could be your problem. Do you remember which way the nose went whem you tried the flip? That may help us understand the problem better.

V3 had a better tail feel for most, personally I never liked it as the cyclic FBL feel degraded so stuck with V2.1. I'm currently flying a beta V4.1 which is not far off V4 which does fly much better than V3. The only annoying gripe of V4 is the odd control twitch, which also extends to the throttle even when on throttle hold. Mine has just flicked the blades round on the auto bearing a couple of times now. In flight there is no problems what so ever, so as long as you're aware of this to avoid problems if holding the model then you're good to go and enjoy V4.
