It came out from our local hobby shop about a month ago they also have pipe on a really expensive box and German words on it but sold here but really cheap about $77 looks like a JP-4.

The internals are the same with the JL .21 pictures you posted early on the thread, I have put 2 gallons on it and I still can't turn it.

The series champ uses it he also own the shop and introduced the engine, the leaflet of the engine doesn't have website on it that's the reason I watched this thread for tuning tips because the engine is the same.

only the two of us was using it when he introduced it, since he won the series and I won one of the novice races in the series ( i came late on the series) most of our racers are now using it
