Thanks.
I didn't get it yet, but i was told it will be just for 5 minutes with good 3300 batts on carpet well, anyway, you can always limit the power...

here you can find dimensions for basicxl

it's the same as novak, so should be no big deal
I own both the novak and the schulze/pletty and the novak dosn't even come close to being the same. Novak's numbers are measured a little bit differently than everybody elses. My Lehner 4200 can easily beat a novak 5800. I had video proof until rcpics deleted my video. I will have to repost is somewhere else. Basically the difference is that novak measures their Kv (RPM/V) with the motor unloaded. Many of the other manufacturers list their Kv at rated continuous current. When I get the time I will test the novak at work and find out what it's RPM is at different loading levels (10A, 15A, 20A, etc ..). I will run the same test on my other systems and then I will have an equal ground for comparison. Another difference is the power rating on the controllers. The u-force is good for 75 amps and the novak is good for 225/pack voltage. So at 7.2 volts the novak controller is good for 31.25 amps. Since torque is based on Amps (In-Oz/Amp) the higher current capability will allow a motor to put out more torque and just plain more power (P=I*V). There is also a factor of 6 is the on resistance (the novak has 6 times more resistance per phase). The novak is cheaper, but it is definately not equal to a Schulze/Pletty.

My Setup:

Schulze U-Force75
Plettenberg Shadow
72/23 * 2.5 gearing on new tires (not sure what the diameter is)
Hurricane 1.165-1.169 packs
I get about 6.5 minutes of runtime on carpet

Here is the German page for the Shadow

i was talking about the size of the motor not the power...
by the way, it's good thing that you explained all the stuff
