Hi "nemesis4u."

No, we did not make provisions for bomb bay doors in the Top Flite B-25 ARF. However, Greg Hahn (who was given a leftover prototype from early in the development of the project) added bomb bay doors to his with a bomb-dropping mechanism. One of the other guys I work with (who was the primary test pilot on this project) is also building a B-25 (finishing it in glass cloth and resin!) and is adding bomb bay doors and the dropping mechanism to his too. Maybe I can get some photos and write up brief instructions some time.

JoeyCoates, the distance from the crankshaft centerline to the fuse side is...(while I run upstairs to take the measurement off mine)... about 9-7/8". Those RCVs are intriguing. Hmm.......
