My engine of choice has always been OS. I've got tons of them laying around. However, I did the review of the JBA 56 for RCU http://www.rcuniverse.com/magazine/a...rticle_id=1194 . All I can say is that this engine is a great buy for the price. I was very impressed with the engine and it performs very well, and the price is very affordable. The review is finished and has been published, and a lot of times for reviews we don't keep what we have reviewed. But with this engine I have kept it on my Escapade because I was so pleased with how it runs. For $79 it's hard to beat the performance of this engine.
