Default EQUIVALENT MOTOR

Which brushless motors are equivalent to a 400?

The Himaxx 2025 can be a good chage for a 400

Thanks,

Luis

Well, you're really not going to find an "equivalent" motor. An equivalent motor would give you the same power output at the same efficiency.

When you go from brushed to brushless, you're after one or more of these:
1. More power.
2. Improved flight time.
3. Lighter weight.

I guess a good question to ask here would be: What battery do you have to work with? That, and your desire to retain that particular battery, or lack thereof, will determine which motor you get.

Okay, so what battery do you have?

Are you willing to also buy a new battery?

What do you think about?

Thanks

HECell 1100's give you about 15 Amps to work with. 150 Watts, give or take.

The 2025-4200 is a good selection. As for gearing and propeller... Hopefully someone else will have some input. You can check around and see what other people are running on their 2025-4200 motors.

I am using a 2025-4200 on a foamy its great , I using a 6.6:1 GWS gear box 12 X 6 APC 11.1 volt 1200 e-Tec battery pulling 10.4 amps WOT about 24 oz of thrust on a 12.2 oz. plane, its a lot of fun!!!! It will goof around, trying to hover, for 15 minutes and still yank out of a hover. It dies about 16-17 minutes, I flew around reasonably flat and level never going full power and got 30 minutes out of it. Jeff

I also have the Himax 2025-4200. Mine's in a GWS Formosa swinging a 12x8 prop with a kokam 2s 1500 pack and C gearing. The power increase from the gws 350c is amazing when you consider that you're pulling about the same current. I ordered a kokam 3s 2000 pack which should be comparable to your 10 cell pack. Motocalc says about 23 oz thrust with a 10x7 prop should fly my formosa at about 44 mph and draw about 12.5 amps static. I'm quite pleased with this motor. My setup only weighs about 16 oz though. It should be able to hover at about 2/3 throttle (if my skills permit).
