Another Video-Li'l Satan with Tee Dee(& troubleshooting the TD)
For some reason up til now, I've posted my previous videos in the 1/2A section.
But here's my Li'l Satan I built a year or so ago. It's flown with a Black Widow, and an RR1. But I got tired of 90 second flights.
Here it is with a Tee Dee .049 fed by a pressure bladder and bolted on with an aluminum backplate mount like the ones Texas Timers sells. It's on 40' lines. I guesstimated the speed with a 42'(including my arm) radius using the video timestamps of a few semi flat laps, starting around 2:15 or so and I figured just about 69mph. The engine stumbles a few times. This one has a quirky needle valve right now. Maybe the venturi needs opening up some more. It has a 5.5x3 Master Airscrew on it.
