You are sorta beating a dead horse here. Your getting 135 out of a airframe designed for 75 or so, not bad at all. To get more, its the same old story, time or money. You allready have a engine that is outstanding, proven by the 135! Your alternatives are either be happy with that speed or invest some time and money into a faster airframe. The most rewarding direction is to design and build your own airframe. From full scale drawings to a completed airframe does not reqire rocket science. After your first one, your stuff will improve in design, function and speed. Start with a good wing (just cause its there) off a quickee or formula. Its general design is poven good, yes you may be able to improve it in the future, right now your a student. Use the Q-500 general moments and streemline them. That 175mph bird will be faster. The wing can be cut down to at least 40" span and not effect the turning or landing ability by much and improve top end. One of my recent creations Jett 60LX/black pipe Q-500 wing cut to 40 then 38" was actually faster than I was cumfortable with. If you gotta have 200mph, buy a formula bird and learn to play with props, fule and settings, the speed is there, you just have to find it. One of the best things about a bird like this is that that Jett 60LX will let you dial in what you want until you can fly it safely. Have seen a good number of decent pilots have a tough time adapting to the high speed stuff. Not as easy as it may look, something you need to get used to. Regardless, do your thing and ENJOY.
