Hey Chad,
The pushrods I made from 4-40 threaded rod and carbon fiber tube. Really easy (and cheap) to do. I just put the control horns on, measured the gap inbetween, cut thr rod, put it on with the #4 nuts, measued inbetween the nuts, cut the carbon fiber tube, put it all together, CA-ed the nuts and thats it! Total cost...$.68 a rod for the 4-40, and 5 bucks for the carbon tube. I was gonna JB Weld them in, but the 4-40 fits perfect in the tube. The control horns are the new dubro heavy duty. I have rocket city on my 33% patty and I must say that the dubro is more stout. I might even pull the rocket city off and put the dubro's on it too.
And for those of you that were asking about #'s for the DA50, I actually ran it today!! And like John (R/C Foolish) said...WOW!!!! This is what I have so far.
Needles set from factory, did not change.

That is all for right now. I will have to get some Menz, 3w, and beila props to mess with. If I had a tail wheel she would have been in the air today...

That type of push rods are great i have them. But to be safe using them, you should glue the alltread in the graphite tube with 2000 rubber tire c/a and put aluminum tube that just fits over the graphite 3/4 to 1" long on the end to keep the tube from spliting and glue it with 2000 rubber tire c/a. This glue will set up and the alltread will not turn, making it into a soild rod thats what you want it to be. That graphite tubing can split if you don't do this. Better safe than sorry.
good luck with your plane
