It didn't get into the air, I had forgotten about fitting the hand me down Ringmaster with a fitting for my remote launch, but I got a test run on the Fox 25 I had fitted it with. Lacking a more modern engine, and having actually read good things about the Fox 25, I opted to give it a try.
It was pretty cold out, around 52deg and trying to rain, so I used some 35% nitro 1/2A fuel (30% castor). APC 9-4 prop. After getting it running (used engine) I gave it a tweak and ended up seeing 13,300 on the tach!!! I was amazed. It may be too much for this Ringmaster.
