Thanks fellas, that was very helpful, now I have flown the alpha with the evo a lot, will I notice a significant power difference from the super tigre? I would imagine I would but just how much of a difference? I also went with the 45 because I picked up a escapade after talking to RCKen and by then I can just put back the evo in the alpha and the ST in the escapade which for such a small plane like the Escapade should make that thing a missle like my pulse 40.
