Old Speedster Firewall

Finally went out to fly the FT Old Speedster for the first time. Things didn’t go well. When I went to taxi around it veered left when I gave it throttle. Then when I took off it kept wanting to climb even with several clicks of down elevator trim. The Speedster doesn’t have any down or right trim built into the motor mount. Every balsa model that I have ever built had both down and right trim. Lacking any other insights I decided to do that with the Speedster. I made a new firewall with a larger hole to pass the motor cables through. And I am going to use the X-mount and blind nuts with socket head cap screws. 4-40. To see the solution that I plan to use for down & right thrust, see a previous post here.
