Twister weight issues
 

We are building a Modeltech Twister, with an OS 46AX about 90% done and are noticing that the tail is extremely heavy..I have the battery and the receiver as far up as we can get them and still balances tail heavy..My first thought was to get a larger engine. Thinking an Os 61.
Is this too much for this plane?

Not sure where else to post this, so I hope its in the right spot...

I would suggest using a four stroke engine to help with weight issues. I am using a OS .70 fs II and still had to add nose weight. [:-] As the CG is moved back for better 3D the nose weight will drop off. With the OS .70 I am flying the plane vertical out of sight but not at a fast speed.

I have an OS50SX in mine and used mini servos on the backend and it balanced fine and very good vertical.
