OS .46 AX?
« on: January 26, 2007, 09:32:39 PM »
Has anyone tried to retune the OS .46 AX for stunt use? It has been a delightful suprise in RC. Absolutely user friendly. It would have to be reworked I'm sure, but just wondering if anyone has worked on it.

Bob,

I've look at this also. And was wondering the same thing. Maybe Randy Smith will chime in.

What's the weight?

Hi Bob

I have not setup one of these yet, there has been no call for it so far, the engine is a little heavy and would benifit from being retimed, I think most who would want this type of motor would find the ST G51 a better engine for the money.  That said  I can see no reason that the OS 46 couldn't work for UC.  This one has the new  Bimetallic Liner material that OS developed  to  end  the  failures of the  nickle plating they had, so it should last a long time , It also has a large crank counterweight  so it should be a smooth runnng motor

It is a little heavy and could use some shedding. I took one apart I yesterday that I have run extensively RC for 2 seasons and the bimetalic liner is working. Very little wear was present. You are right, the engine is a very smooth running motor.

Bob, I have an OS.46AX also. Stopped flying R/C except for some occasional glider fling with mu Riser 100.
Seems to have plenty power, but can it be tamed for the "stunt run"?
I've often looked at the engine wondering if it would be useful to convert it to C/L. If you have it converted could you post some followup information on it.

I have not tried a stunt run on it. I am sure it would not work out of the box. Just too much power there. It has become the favorite motor of a number of members of my RC club because of its user friendliness, smoothness, and power. I've used it in everything from 3D planes to biplanes to conventional aerobatic planes to small pattern planes, and even dropped one into a speed wing while I was waiting for a Rossi to arrive. Probably was one of the fastest flights and AX ever ran! While it has lots of power its not an 18 to 20K rpm motor.  Itis  one of the few RC motors I never reach for the electric starter for. It does a perfect one flip start every time. But the flip side is its not set up calm and sedate like an LA. It is as you know a real powerhouse and would certainly need to be reworked by one of the engine guru's to work at all. That's why I posed the thread, just to see if anyone had done it.
