TT 120 or even a EVO 100. dose any one have this plane or knows how
she handles? im worried about the engines weight up front.
please can u help...THANKS

Here is mine. I changed the location of the gear and recovered. Also up in the front is an OS 1.08. A bit of an over kill but plenty of power. Speed is good too. Whatever you pick, your prop will be the key. Keep your pitch number close or the same as the length like a 13/12 or 13/13 or 14/12 or 14/14. I also suggest you use APC.

One bad habit on mine which is obvious from to much engine is you need to have some good elevator control on takeoff or it will nose over. It's quite a balancing act. Also make low approaches when landing. They like to come in hottttttt.

Your best bet these days for an engine is the Jett 90L.
