View Full Version : What Electric Motor for 60 gram Cessna?

Recently I rediscovered an almost finished 24" wingspan all balsa Guillows?Cessna 150 that I built with my daughter about 15 years ago. I thought it would make a good plane to fly indoors if I converted it from freeflight rubber power to electric R/C. It looks like an AR6400 "brick" would be a good control unit. Would any experienced indoor pilot be able to recommend a motor (brushed to go with the AR6400 I believe)? By weighing the components I am predicting that it's all up weight will be around 60 grams.

Thanks,

RB

There are tons of Guillows conversion threads on RCG:

As for a motor, I haven't seen a brushed setup yet. Most of the conversions require using a 1S brushless ESC and a 5g outrunner to get sufficient thrust.

There is an off the shelf AR6400/brushless ESC/motor combo available from the UMX Beast that would likely work well. The Beast weighs in at 2.35oz.

AR6400 with BL ESC:

BL Motor:

#EFLUM180BL

Other motors I would consider from HobbyKing:

#HXM1400-2000 5g, 2000KV
#HK-AP05-3000 5.4g, 3000KV

Thanks philipa_240sx,

Didn't realize there was a brushless version of the AR6400. That's perfect. Makes finding a motor much easier. Also should have know I was not the 1st to think of converting a Guillows. Will check out RCgroups threads.

It's pretty new... I think it came out around the same time as the UMX Beast (which also has a BL motor).

E-Flite also sells a 180 class motor, not sure if it's the same one in the Beast:

For something a bit more... lets say 'premium' look at the Mighty Midget motors from BSD Micro:
