Rimfire motors, good or bad?
So for the past day or so I've been reading about Rimfire motors.
Apparently, from reading here, a few years ago these had a bad rap.
Are they still not that great or did they increase the quality, in the past two years or so?
Reason follows another thread where I have a Spad and Fokker, where they're (Rimfire) is the recommended motor.

Quality is okay... ridiculously inflated ratings for power capability are the problem.... if you want an immersion heater run a Rimfire at its rated max and see what happens... run 'em at normal power levels (say, 3W/g) and they'll do fine.
Your 54g Rimfire 28-30-950 is rated for 20A/220W, while a 56g E-flite 400 is far more sensibly rated for 10A-13A/~110W-140W.
A 102g Rimfire .15 is rated for for 650W (6.37W/g)... most other 102g motors (2814-size) are rated for around 300W (3W/g).
