Motor Question

[jima]

Here is the spinner I use on the Rimfire motor along with the adapter nut. It also works great with the OS motors but you don't need the nut because the OS collet has the end threaded for the screw.

Here is the spinner and nut that I'm using with the motor:

The nut is:

I've most of the approved at some point and I like the fixed shaft on the Rimfire because it repeats and you don't have to mess with sliding the collet to the right position each time you install it. It also gets the prop and spinner closer to the bearing of the motor and is therefore more rigid. My opinion.

On the GP Proud Bird you use 8 of the 3mm spacers supplied in the kit and the position is set.

"SNIFF TEST"
The NMPRA has said DO NOT DISASSEMBLE YOUR MOTOR AND TURN THE SHAFT AROUND!
It can be done with out taking the motor apart. Just place the new 5mm shaft in and puss 1 out with the other 1. Did not take it apart!!!!!!

If you remove the original motor shaft you have disassembled your motor. You can't do this. I can't figure out what you don't understand.

So, in summery:

Buy a motor, spinner, collet and prop. Put it all together without removing any parts. Ensure the collet is seated and you can not pull the spinner/prop off with your hands. Next, design your motor box and cowling around that. If it is an ARF and you are using something other then the OEM recommended motor and collect assembly, there is a 50% chance you are screwed.

There. Done.

(Sorry Dan, could not resist )

Sorry this doesn't make any sense to me. What are you talking about?

50% screwed for what?

It was a joke Dan. I was just trying to lighten things up a little.

But, I have set up at least ten 3d aerobatic airplanes for my self and other people, and to get a proper spinner gap and to get the collet to seat all the way down, in almost every case that I was not using the recommended motor and/or spinner collet combo, sliding the shaft one way or the other was how I solved it. hence, on my shoestring it never occurred to me that I rendered the motor illegal by sliding the shaft. I have routinely left the c clip off, the logic being that there are two set screws and if usimg GPs collet, a third set screw, the chances of the motor separating, is very, very low, and even if it did, it would be contained in the cowling. So it did not cross my mind. Now I know that for EF1, I need the c clip.

So Dan
If I bend the shaft of this motor in a crash. I can not repair it right.

Kevin,

As it stands today, NO you cannot repair the shaft on this motor.

1. You cannot take your motor apart.
2. You cannot replace stock items.

Just asking how would you know if it has the OEM or a replacement shaft?

[GaryS]

Would it be legal to have a replacement piston made for a Q40 engine, even if it looked the same??

It doesn't matter if it's detectable or not! If it's not stock, it's illegal!

[Dave Yost]

Every time I try to figure out Amps, Watts, C ratings, Props, ESCs, Shafts, Collets and Electric Motors it looks like this: If I have 10 ice cubes and you have 11 apples, how many pancakes will fit on the roof?

I have to disagree. The answer is twenty one and aliens don't where pants. You silly goose.

So Gary buy what you said is, If you losse the fit on your Q/40 engine you can not replace it, The engine is dead now, RIGHT!!!! it is no longer stock

[kane]

Kevin

The difference is you would replace parts on your QM motor with stock parts sold by the mfg. and it is ok to disassemble your motor in QM. However it is not ok to go to McMaster Carr and purchase piston material and manufacture your own components in your garage.

Rimfire DOES NOT sell replacement parts and furthermore DOES NOT recommend turning the shaft around.

What if I had a bearing go bad can I fix it?

[RCjunkie]

Plus Danny I was using Gary way of thinking

[kane]

Kevin,

You CANNOT replace your bearings.
