Whoa! Sorry, I didn't mean to start a brand A vs. brand b vs. brand c etc etc flame war here...I was just deciding on which engine to buy...I have been flying for almost a year and within that year, I bought a Avistar, a Ultra Stick .60, and a Eflite Tribute with park 370 BL motor (btw, I'm 13) and I can beat the snot out of all of them and fly em upside down from take off until landing...now I was looking at a new engine for the Avistar so I could have more fun with it...now I'm deciding between the TT .46 and the OS .50. I like OS because of the quality because price dosen't matter to me, I just want a good, reliable engine...that is why I posted here, so I could get some opinons from people that have been flying much, much longer than I have and have more experience than I have...the only engine I ever bought is an OS so I that is why I put the TT...to get more experience with different engines...

Okay? Thanks for all the help....
