RE: Not another 4* 40...
I powered my last 4*40 with a TT Pro .46 and it flew great.
I just picked up a 4*40 ARF fuse (needs lots of work) and a full kit at an Auction. I'll put an AXI 4120/14 in the fuse and build the wing in the kit for it.
Then, I'll build the fuse from the kit, but with a modified wing saddle. I'll put in a scratch-built wing with a Selig 8036 airfoil. Had one of these before (lost it due to pilot error) and had a ball with it.
