True, the TeeDee venturi is a big large for suction, but I solved that by gluing it shut with JB, then redrilling it to usable size. This was accomplished with the venturi unscrewed from the engine. This setup works fine for stunt and scale and the loss of power is minimal.
Hey Paul, The post I deleted ( because Keith T. took exception to it ),
talked about all the TD / Medallion testing I did and I linked to
the video of it flying.
C'est la vie.
I took your advice and sleeved the TD .049 down using J&B
aluminum tube. The TD runs very decently with the sleeved
venturi and sucks the tank dry every flight.
Thanks for your spot on help.
FWIW my
.049 Medallions also run fine but aren't as easy to
start. I guess everyone's experiences come down to the
individual engines.
