There will be two new versions coming out depending on what you want for prop and rpm. They are supposed to have an integrated fan to force air through the motor. One is a high rpm version that is set for an 18-19" prop pushing around 7000 rpm I think, the other was discussed based on the prop I was using in France, the plan is to bring up the current (and therefore rpm) on the 21x13W....probably around 6600 or so for about 69-70A. The current motor may still stick around I dont know. This motor would not run the 22" props but would open the door for more use out of the 21 and 20" sizes and bring up the speed range a bit. Bernd B. was running the high rpm version in France, the other version was simply discussed with Bernd, myself and the Pletti's. Now that they are back from Tucson they are going to start designing the second motor.

The cooling fan has been in use on the Orbit series of motors for some time, as well its on the Terminator and the new Predator motors so its a quick fit to the Xtra series as well.

As for the temperature, even running a standard full spinner with no additional cooling in Muncie this year (90F+) I was only up to 140-150F which was in line with what everyone else I spoke to was getting. I talked to the Pletti's about temps in France, they indicated that 70-75C measured right after a flight on the motor can was still acceptable. 140-160 though is fine.

Around here we are usually around 80-85F in the summer, I barely get much over 120-125F, sometimes 130F.

I am only drawing 61A though.
