For your engine, the best plane in its class is the Alliance then comes the Synergy but of course you have to do your part by building it straight. I had had a blast building the Alliance and the Sky Star I got from them. If ever you decide on a bigger plane (90 class) dont get the sky star, get the Topstar 110 and be sure to power it with YS110 or and piped OS 90 or 120.
