She's gonna have plenty of vertical for those big maneuvers now. Glad you got the DLE. I have a few friends that had the DA35's in 3D planes. They struggled to keep them in tune. Creative install bro...well done.
Wow - That was some very nice engineering to get your new '35' squeezed into your P-51. Your 'quick & dirty' methods sure did work well to provide a beautiful / functional cowling. And I love your idea to have exhaust stacks that can actually provide a vent for the hot air to exit more efficiently. Your're gettin there !
