I have a tribute and running a 370 with the standard gearbox that comes with the tribute. I am running 3cell li and using a 12.6 prop (just for testing motor).
The problem is when I get to about half throttle, my gear box gear lifts up on the shaft and then comes disconnected from the motor. How do I stop that from happening ( be nice, Im a newbie .

Also, I got a prop adapter from Chiefs to use a APC 11x4 prop. How in the heck does this thing attach to gear shaft??? Seems the gear shaft is much thicker then the adapter. Pictures would be a great help!!!

Thanks for your help!!

You're trying to put too much power through the motor. A smaller prop will help.

The prop adapter is obviously the wrong one. It should simply fit over the end of the shaft and clamp on with a collet or set screw.

If you've got a nearby hobby shop, take a look in their brass or aluminum tubing assortment. You should be able to find a piece of tubing or a combination of two to make a bushing for the propeller. Just make sure it's shorter than the prop hub is thick, so the washers and nuts can tighten down on the prop.

Matt,
When you say to0 much power, are you referring to the battery or prop? or both? Battery power is a 3 cell li 1500, using a Jeti 8 speed control. It is the upgrade that Chief Aircraft sells with the Tribute. Dont understand why Chief would give me the wrong prop adapter.[:@]. They sent me a 11x4.7 prop...is that too big too?

thanks for your help Matt!
