Plans? Right inside the BlackHawk Models kit box! Act fast, he is discontinuing this model, unless demand picks up. Even if Larry Rice has quit making the kit, I suspect he can still sell you the plans. Larry lurks on this forum, so perhaps we will get word from on high.
Pushrod is the smallest carbon tube you can find to fit 2x56 pushrod ends. You just have to check all the sources to see what is available. I pick up stuff wherever I find it and then haven't a clue where it came from when I use it. (Most modern hobby shops are pitiful compared to MY workshop!)
My philosiphy with materials like that is "When in doubt, buy it!"
An altenative is to get 1/16" carbon rod and join it to the purshrod ends with a length of aluminum tube over the joint. JB Weld is the glue of choice. I always make my pushrod length adjustable so that I can tweak the trim to match inside and outside maneuvers. By biasing the bellcrank, you can make one or the other more sensitive, then reset the handle to neutral.
I am a great believer in 3" bellcranks and longer horns on 1/2A models and 4" on larger ones. Bill Netzband actually calculated the "Netzband Wall" where a small bellcrank can no longer provide the force to drive the elevator adequately. In addition, you have a hard time desensitizing a model to be competitively, precisely, stuntable with a 2" bellcrank. Adjustments just become too critical when you have such small dimensions to deal with. All you have heard about 1/2 A models are "squirrely" is due to bad trim and lousy control setup. I can trim a full stunt 1/2A so you can only fly level, no capability for stunts. Then as you increase the control throw and move the cg back you can tune it anywhere you want.
