I've been looking at ESM Warbirds that Troy Built carries,in particular the P47 and the Mustang. Just wondering if anyone has one of these birds and how well are they made, as well as any poor construction issues. Both call for a 26-35 cc engines although I would probably use a DLE30. How good are the electric retracts. Ive seen the video on the version 1 and they are painfully slow. The videos Troy Built shows are very nice looking but the real truth is from someone who has built one.
