Been working on the baffle plate for the airplane with the quad motor all morning. Still working on it! LOL!! A real PITA.
Meanwhile, I installed the CDI as well as the servo pushrod for the throttle.
I am using a New to ME pushrod, which I have never used before on a 40%er. But, I have used similar many times on airplanes back in the day, nitro airplanes, that were now, to me, small, but back then, were huge!
It is this Sullivan "High stress rod", which is the largest I have ever used and it is quite stout!
It allows me to use 4-40 pushrods that threads into the yellow inner tube. then, the yellow fits into the black sleeve, and thus, the pushrod.
I have never used one of these before on a 40%, and in all my other 40%, I have always used a direct pushrod for the throttle servo, and the throttle servo was always very near to the motor and the headers. This past year, on my Dalton Yak, I had a situation whereby we were flying in the summer heat, it was a very hot day, and then all of a sudden, we lost throttle control. When the airplane landed, the throttle servo would not work. Then , 30 minutes later, it started to work again, and I did change out the servo, but I wonder if maybe it had just gotten too hot.
SO on both of these, I will place the throttle servo away from the heat.
I have not committed yet, but I was considering installing the throttle servo in the rear bay, for another reason, which is, to help distribute the weight, since this airplane will want to be nose heavy. I am hoping to place the radio, the batteries and this servo in the rear bay, and use a heavier pilot, to help improve the balance of the airplane. And avoid having to install the batteries way back. right now, with the canopy on, and the cowl on, but no wings, if I raise the airplane from the wing tube, it is way nose heavy.
I installed both CDI, and I also want to try to keep the spark plug cables as well protected as possible, and as well as isolated. Trying to keep these cables as far away from other cables or wiring is important. Too many times, I have seen airplane set up, where they bunch them all together, and I just do not trust that. Again, I am OCD.
here is the throttle pushrod set up.
I am using a 4-40 screw into the DA throttle arm, and there is blue LOCTITE as well as a locknut behind the screw and monster ball link for a 4-40 screw.
here it is with WOT.
As I mentioned, I have not committed yet, but considering installing the servo somewhere around here. This area is behind the wing tube, and behind the fuel tank.
