Great to see the ole Spectrum in the air. I am happy that it is in the hands of someone who will enjoy it. It was built back in about 1985, so that makes it 30 plus years old.
As an observation from the video, it appears that the engine peaks a little more in the outside maneuvers. Perhaps an 1/8" shim on top of the tank might help. Of course, watching a video can be deceiving. One thing for sure, the DS 61 is doing a good job. What a perfect stunt run!!! Is that a 13-6 Rev-Up prop? Good choice.
