Nice work, but why ruin the scale outline with servo's hanging out the side? A DLE20 with a 17 x 6 xoar prop flies mine all day long with plenty of power and very scale like at 1/2 throttle. I also have a smoke system in it and it only required about 5 oz of lead with the 20, and that is only because I like it a little nose heavy. I'm not sure why so many overpower their biplanes. The real PT-17 only cruised around 70 and the supers had around 350- 400 hp just for aerobatic purposes. But to each his own I guess. Its a shame they jacked the price so high now.
