What's the difference between these two engines (besides the fact the .50 is ringed)? Is it worth the extra money to buy the .50?

The 50 SX has about the same power as a OSFX61. but it is about the same weight and uses the same mount as the 46AX. It also turns a max of 22000 rpm. It can be flown in 40-60 size aircraft with impressive performance. I just bought one and it is amazing. Well worth the extra bucks. I also fly the 32SX which also performs extremely well. I do not own a 40 46 or 61 as these 2 engines cover that power range.

Cheers Rick
