Red Aero RC MX2 Jam (0 min 46 sec)

Mine is nearing completion with the OS. I had to make a 1/2 inch exhaust spacer (nice to have access to CNC tools!) so the end of the Pitts muffler was not too close to the CF throttle pushrod. Do you think the spinner to cowl spacing is too much (about 4mm)?

Wont affect how it flies bit astheticly(spelling?) it would look much better about half of that

The spinner could be a little closer to the cowling, but It all depends on how perfect you're trying to get it.
Cowl cut-outs are nice and neat.

I have an lathe, I can take another .1 inches out of the standoffs easily.

Kenn, did you have to cut any room off the cowling for the hall sensor up front?

Yes Devan, just a bit. Not much.

Ok cause i noticed mine was hitting and didn't know if it were just mine or everyone's would be like this.

What engine has the Hall sensor in that area?

What engine has the Hall sensor in that area?

DA 50, im using pretty long stand offs though im sure if i used a smaller one i wouldnt have to cut any room for it

think 2.25" is what I used. I have it on the front end of this thread someplace.

Do these planes normally run nose or tail heavy? With the OS I am using 0.5 inch "standoffs" but will go to 0.4, so I am thinking the OS engine will shift the CG rearward as compared to a DA50 or DLE 55.

Not sure not very many of them out there yet that i know of. but the OS shouldnt be to different in weight from the DA 50.

It is a little heavier, the OS is 1.59 Kg and the DLE-55 is 1.47, I weighed them both. My point is the OS sits considerably rearward.

My point is the OS sits considerably rearward.

It may sit rearward but the weight is still there and it has a lengthened crank shaft. The weight is still as far forward as it can really get so it really shouldnt be to different. Think of it as like a balance beam u can have the same amount of weight on each end and im sure you could move one further in and it would still be balanced very well. It will be different but not by very much considering there is only a slight weight difference in motors.
