Here we go again!

I cheated here...I had the old firewall. I carefully measured my previous Wild Hare to mark the throttle and choke pushrod access hole. To measure this passageway I initially made a smaller hole and worked outward little by little in the direction I needed to go for the pushrods to work freely. You can see that the cutout is generous, but even after over 100 flights the firewall didn't show any signs of cracking or flexing.

I made sure to put the DA-50R inside a protected box or bag while I was cutting and sanding since I didn't seal off the carburetor and exhaust. The last thing I wanted was to get dust inside a model motor that cost as much as a rebuilt Chevy shortblock V8.
