You're welcome - I am assembling a twm 70" P47 myself - getting pretty close to finished now, but I am a slow assembler so it will probably be a few more weeks till it's done. I'm using a Zenoah G26 which i already had on hand, and air retracts instead of the twm retracts since it calls for 2 retract servos and I like air/spring down retracts. I moved the servos back behind the CG to help balance it and also to give access to maintain the fuel tank. I assembled it to check the CG again last week and it balances almost perfectly with no weight added. The p47 is a very well designed airplane - I consider TWM and Top Flite to be the two best warbird companies.
