Ikarus › H8 Motor Mystery Collet

Having just upgraded my Eco 8 to brushless with the H8 motor I am at a bit of a loss to know what the 5mm alloy collet that is now supplied with the motor is for. I am told by the distributors that the collet was originally not provided but is now with the newer stock. They dont know what its for and say to just fit the pinion.

The pinion lines up correctly with the main gear so the only place for the collet is after the pinion. There is a small stub of shaft on the top of the motor but I cant think why you would need to fit it there.

I also notice that the top of the motor has 4 machined and threaded holes. Could this be for an additional fan ?

Any Ideas ?

I just left the collet in the box, maybe its for use in fixed wing pushers?

Extra holes could be used for cooling fan, but my H8 runs so much cooler than my AXI I don't see the need at the power levels I'm flying.

The collet is to hold the bell on but it is unlikely it would ever come off anyway. Its also in the way if you fit the collet before the the pinion then the pinion does not line up with the main gear. Either remove the collet and then pinion stops the shaft bell sliding off or put the collet on and turn the pinion upside down.

With regards to your question about LiPos, if you go over to the Ikarus BBS and look up a use called Gonzo he sells 5000Mah packs so you only need a 3s1p or a 4s1p depending on what your after. With the 4s people have reported 20+ minute flight times and they are a lot cheaper than TP packs. A lot of people over there are using them.

I use a 3s3p pack of HD 1500's and they seem fine, good for 15 minutes.
