good question.

in short, it's just about what I've been able to test. With the original design, I had concerns about getting enough prop on the motors to get the thrust I wanted. It worked fine for the original LensRC17t. As it turns out, you can actually over prop the newer motors using the VarioProp 6.5" blades with all the pitch wound in. So this allows the cooler motors to get their thrust numbers. I also love the results. On the cool wind, the 2S setup is simply great, but you can put 3S in there without any changes and get a ballistic setup (with some throttle management to allow the motor to cool, can't go full throttle the whole flight like this).

I think the hotter motors should work great, and I'd love to try one myself actually. In my next build I'll be trying out a LittleScreamers ParkJet motor. The hotter motors will certainly allow for the use of smaller and cheaper two bladed props. Should be a great setup, but I don't know from experience at this point (note: the hot CustomCDR equates to the LittleScreamers PurplePeril, the ParkJet is even hotter).

It's just that I can only put in an "official recommendation" on what I've personally flown. People are certainly free to experiment though

A few people don't like the VarioProp recommendation, but I love the look and the flying results I've had. If you want to try the hotter motors, start testing with the pitch wound in (or maybe smaller blades). With the cool motors, starting with the pitch opened up should get a flyable result.

I also use phoenix 10's. The cooler motors also keep the Amps well below the 10 max.


...you know, I wouldn't mind getting me a CustomCDR hot or a PurplePeril to test out and get back to you with some actual results [8D]
