I had a Fox 2.4 on mine and it worked great. The fox is the same engine as the Brison but the crank is polished. I put the fox on my H9 Cap. I am going with a ZDZ 40 for my new Edge.
I just spaced the engine out 3/4 of an inch and moved the cowl back to match. This helped with cg. I also put three servos in the tail.
