HI there,
I have ultimate with saito 125 engine, i have a problem if i increase power to full the plane nose went down but with half power it is ok, could anyone help me please and tell me the reasons of that with solutions if possible? Thanks
Sounds like too much "down thrust" on the engine mount - install a washer between the engine mount and the firewall on the two lower mount points on the firewall to reduce the down thrust, and see if it flys better.
