Is there a specific plane/project you have in mind?

Generally, brushed motors are run with gearboxes because their Kvs tend to be in the very high ranges. In some ways that makes them more versatile than something like a brushless outrunner because you can tweak gear ratios and get different effective Kv ranges with the same motor (assuming the gearbox has provisions for different ratios).

Tower still has some brushed motors and gearboxes listed. BP also has some brushed motors, gearboxes, and motor/gearbox combos. For faster-flying models, Speed 400 motors with small direct-drive props (6V and 7.2V winds) aren't uncommon and would work fine with your 20A ESCs.

You can also use those ESCs to control LEDs or pretty much anything that requires variable direct current. They're handy to have around even if you're not flying them.

I flew brushed motors for many years before brushless motors came within my price range, in fact my B-25, (93" span), only got converted to brushless within the last two years. Also my GWS C-47 is still flying with brushed, and my electric glider. So don't give up on flying brushed.

Many of the cheaper trainer planes still have brushed motors.

As for where ?, as you're in Australia, I don't know, but many model shops still probably stock some. Many RC cars may still use brushed motors, so there is a possible source. Also do a local search on Graupner Speed motors, probably the '380' and '400' series, as the '600' series may be too much for the 20A rated ESC.s, (depending on which prop and what voltage).

There are also the cheaper Mabuchi brushed motors, sometimes referred to as 380's, 400's and 540 size.

There should still be gearboxes and belt drives available if you want to turn larger props.

A couple of smaller brushed motors are still ideal for a simple twin.

I even converted a glider to removable electric power, (to also keep it as a pure glider), with a couple of Speed 400 brushed motors in a simple removable pusher rig.

That's a neat twin glider. I have never changed out the brushed motor in my Easy-Star; when/if I get a Twinstar, I will probably keep the brushed motors since using brushless motors requires a brushless ESC for each one -- the cost goes up rapidly.

I also use LIPOs and land when the power diminishes, so the lack of a LIPO-specific cut-off is not a problem.

howell

Also have a geared 600 which will go in a Great Planes Electricub one of these days......

A servo motor won't swing a prop... and I wouldn't waste money on an entire R/C Car when you can get decent motors from GWS and Great Planes for under $10. http://www3.towerhobbies.com/cgi-bin/wti0093p?&C=GHA

20A speed controls should be good for up to a Speed 400.

i dont really want to spend 10 bucks on a brushed motor, il just keep the ESC's for experiments and random eletronic tinkering and stuff.

I'm surprised no one hasn't mentioned Stevens Aero.

colj00, if you need to know where some of the Australian suppliers are, there is a forum dedicated to Australia where you could ask some of your compatriots -

There are quite a few regional forums under -

Why do people use brushed motors in gliders? Is it because the motor is not used as much and it would be cheaper?

Other than cheap they are high KV motors and work well with the small props and the mounting is simple with the pusher pod type designs.
