I bought a Nitroplanes "Ultimate 40" and it is a great little plane. However, I did not buy from them, but from the classified on RCU. It is an ARF. The plane does not have cross hairs for mounting the engine. There is a degree angle of the firewall, and the circle is right in the middle. I was told to just mount it in the middle by one guy.
No one has been able to help me otherwise. I was told by another guy to ask Jose on RCU, who is a tech that builds planes for Nitroplanes about this and he would be able to help me find the specs for mounting.
So, anyone, please??? Ultimate 40, yellow, black and white just like the nitroplanes bip. Anyone no where to mount the engine.

Thank you so much in advance.
