This is my first Protos, my question is this belt drive, doesnt seem to let the heli free spin under no power. the kit is brand new, the weather has hindered me from flying, will this break in, or do I have something wrong with the build.

Heli's its not a hobby it's a curse!

As long as the belt is not super tight, that drag you feel when spinning it by hand is normal.

I just got a mini protos as well and its my first protos kit. I thought the same thing since I am used to Align helicopters. You have 3 tension points on the protos and need to loosen your tail boom and tail brace to adjust the back 2 tension points (about 2-3 mm of play in it) and you need to loosen the motor mount and the part that holds the pinion on (sorry i forget that part name) and then adjust that so you have about the same amount of play. It's still not as free spinning as an align heli, but I have just about 2mm of play in the front and back and I am not experiencing any belt slipping or excess wear of the belt from it being too tight. It is definitely an AWESOME heli!!!! I love mine and it turns heads at the airfield every time it flys!

With the friction from having the direct drive belt it is a little more tricky I tried an auto from about 5-6 ft and had no problem just to get a feel then tried it from about 30 feet up and managed to not crash. I did, however, have to be much more careful with the collective. If you start bleeding off the head speed where you would with a 450 pro or rave 450 then you will definitely lose control. Needless to say that was probably the one and only auto I will willingly do with this helicopter haha I'll stick to using the 600 for autos!

The regular size Protos autos pretty good. Stretched version even better as expected, but i wouldn't even try on mini. There isn't enough inertia for the belt. If you need to practice autos, 450's aren't forgiving. Use a bigger heli to pratice.

I think you all are missing the point here, what I'm trying to get across is the lack of head spin when under no power.....hmmmm like it has no one way.

like when you hand spin the head on the bench and see how many revos it will do before stopping ?

Make sure you put the one-way in the correct direction. If it is in correctly, and your belt is tensioned per the manual, you should get maybe 2 turns after you spin the head with blades by hand. That's how many turns we got with the full size Protos. If you are getting none. Then your belt might be either too tight, or something is binding somewhere. Check the tail shaft without the belt on the pulley. Make sure it spins freely even when moving the tail pitch arm.

to see if the one way is working right grab the head and turn it clock wize, the motor should not turn, then turn it counter clock wize and the motor should turn !!! if not some thing is not right.....
