500SH Information

500SH is our first 500 size motor designed for use in T-Rex, heli's and Jets. We focused on similar performance to the 450TH at lower amps. A slightly lower Kv and larger pinion of 14 to 15 should get you the extreme performance you desire. Other size pinions are available from 11 to 15 for your experimentation. I'd love to hear the results.

 

Many have asked for a motor that can be mounted as a tractor on the rear of a Jet. This pushes the balance closer to the nose and requires less chance of having to add weight, as well as protects the motor. I have done some experimentation with low speed bells and feel it will be ideal for fast pylon racing airplanes. This motor mounts perfectly in our L Brackets and with a 3.17mm prop adapter you'll be screaming around the flying field.

Reports from Customers

I've received reports from customers who say this motor stays very cool at higher performance where the competitive motor runs hot. This will be our most efficient 500 size motor. The guys wanting severe power should consider the 500TH. The 500SH is lower Kv, and would require a larger pinion or higher volts to get you over 3000 RPM. If you want to go to higher efficiency with less than 3000 RPM on your heli then this is the motor for you.

 

Jet guys - 500TH is the ticket ! 500SH is for guys setting up for speed and lower than 30 amp draw.

 

And a HeliDirect report:

"I started out with 15tooth on 3s. With 335mm blades, I was getting a head speed of 2950rpm at 0*. The power was decent, at about 11degree of pitch, it pull about 22amps, which surprise me of the low amp draw. Power was good enough to 3D, but diffinitely BOG a bit. It probably need a 16 tooth to speed up the head speed to 3100-3200. I do not have a 16 tooth at this moment to test. But I do have some 4s laying arround.

So I put it on 4s 2100 (a bit heavy, but I thought the light weight of the motor should balance out with the big pack). With a 12 tooth pinion, I get 3200 head speed.

Full pitch, 27amps, almost 420watt, power is awsome, no bog... what I love the most, after 6 mins of 3d-ing, the motor temp was arround 95F vs my Medusa = 150F."
