Oh God,I've created a monster!
Meanwhile,back at the ranch,my 051 reed now sports a 1 1/2 " neoprene tube slid onto the plastic backplate and the r/c carb off my old TD 051. The tube runs through the firewall,so the engine just mounts as usual. I thought the long inlet tract might interfere with the mixture velocity,but in practice theres no difference. Thus the carb would be back past the fuel tank and in the battery area,if it was in a plane ! This opens up all sorts of possibilities. If the tube was longer, the carb could be mounted anywhere. Under the engine,or, next to the throttle servo. Throttle response was OK,considering the crude old thing it is, never worked too well on the TD, but it seems happier on the reed. Idles down to a steady 8000 or so.No tacho, but, I reckon that'd be close. Tomorrow I'll look for something a bit more "state of the art". All in all I'm pretty happy with Frankenstein ,and can't wait to get it in the air.
