I recently electrified a Dogfighter SPAD,
The photo shows the original setup with an 1100KV Motor and a 30A ESC. It flew nicely but no real speed.

I'm now using a BL2815 1400KV with a 60A ESC, 8 x7E prop and a 30C 2200mah Lipo. It's drawing 430W . I get around 4 minutes flying which is long enough because it's ballistic!

Currently building a smaller HOR type plane but using an aluminium "U" section for the fuse, no elevator just elevons!
