Hi Bob,
I think it’s a OK .35 “Hot Shot”, I had one when I was a kid. It was my first big Motor that my Dad bought for me. It ran pretty good but not the power of most, a McCoy Red Head 29 would kick it’s but. It was perfect for light weight Ringmaster S-1 or Flying Clown ( used it to learn to fly upside down).
Later,
Mikey
