Just make sure clevis for aileron,ruder and elevator to be secured or get a better quality clevis. Also you may need to adjust the idle mixture to keep the engine running smoothly, because the inverted mount and the fuel tank position very high caused the engine flood. Double check the bolts for the engine mount are tighten enough. I found after 4 or 5 flights the engine mount get loosed. It is light and fast airplane but have those things checked.
