Did you remember to rebalance the blades when you cut them down??? That might explain the vibration and rumble.
Thanks for sharing it with us.

Yes i balanced them again. The main problem i think is the axle. It might be a little bit curved or otherwise out of balance. I'll make new for it when i have some spare time in hand. Best regards jaskiainen[ Parent ]
