Hi Guys, I'm having motor balance problems and need some help.

I'm using the 'Hobbycity combo' for my FunJet Ultra and despite carefully balancing props cannot get past half throttle without serious vibration. Note this is static ground testing, it has yet to maiden. I'm aiming to use a APC 7x5 nitro prop.

How are you fitting the round section of the motor mount to the fuse? I've used what I'd consider more than adequate CA (not drowning, just standard amounts).

How do you fit the alloy motor mount to the plane, I've used the stock screws but does the adjustment screw need to be replaced with an embedded screw?

Is more reinforcing/glue required?
