Default Logo 200/OMP M2V2 tail rotor upgrade?

Iíve seen some videos of people flying 3 and 4 blade micro drone props on the tail of the M2. Got my Logo 200 a week ago, and besides trying to calibrate my brain for a small, fast, high head speed Heli, the tail is really my only complaint. Iíve been in a few maneuvers where the tail has blown out, mostly in the low/medium HS but also at 6000rpm if thereís a 5-7mph wind.
Any tried and true 3 blade drone props that can be recommended?

VBC related SIDE NOTE: messing around with the gov gain, canít find the sweet spot. That German guy Daniel Weideman (helischule Gonzales) promised a tutorial on optimizing the gain back in December but hasnít published it.
Just looking for a more stable head speed without any surprise altitude drops.
Good starting point? Would pitch pump help make the collective stops crisper?
Thanks

I wouldn't recommend changing the blades, it would be very easy to overload the motor and burn it or the ESC out. It wont help the tail anyway. Direct drive tail helis do have inherent limitations because the tail rotor is fixed pitch and only runs in one direction, so it can only produce thrust to yaw the heli in the clockwise direction. Anti-clockwise yaw depends on the tail rotor almost stopping and torque from the main rotor to yaw the heli.

This works surprisingly well but you can catch it out by unloading the main rotor so there is torque, this can create a 'blowout' in the opposite direction to what you would normally see... No tail blades can help with this.
Number and Beserkr like this.

Thanks, just thought Iíd ask. Iíd seen some videos of Thai pilots with a 3 bladed tail prop. I guess Iíll just enjoy it for what it is!
