I have a Super Tigre 51 ringed version turning a 12x6 and it is a super combination. It is in fact a little overpowered for scale in flight performance. Will pull vertical for a while into a stall and then magnificent spin back down.

I have had a great time flying mine. JR 8103 and JR servos and receiver on a 1000 mah pack. Used the pack to get the balance correct. I used a slimline pitts style muffler so cowl installation is clean. I also used safety nut on prop installation.
