carb arm extention

I am not all that familiar with the MDS38 except that we were not able to get any of the three that have showed up at our field over the years to run properly in any heli. Yet they are not too bad in airplanes. It seems they use the same carb in both....not a good thing as a carb for a heli requires a different fuel metering system.

But one way I had solved this extention requirement many years ago in a Shuttle/OS combination was simply to use a longer 2mm bolt (e.g. M2 x 16 from DuBro) through a KSJ 181 ball joint with a spacer made from an appropriate aluminum tube between the ball and the arm.

I had that plan except for the spacer..Doh!!! as for the MDS I have the heli version are you saying that you have not been able to get that correctly. The guy I got it from was breaking it in for use in a plane but changed his mind.

I got one to run fairly well in AGRAV's Century Schweizer 300. But, it was inconsistent once tuned.

The problem with the MDS heli engines is much like their airplane motors they take FOREVER to break in. Most guys bail on them long before this happens.

If you have the patience I think you could get it to run ok.
