Egad, why didnt I think of that.
I use a film canister tank for my 049,
I cant believe I didnt think to ditch the standard tank and make a bottle myself.

Looks like I need to buy a soda in a bottle smaller than 2ltr for a change .
Wonder if the soldering-iron-hole trick works on them like it does on the film canister tank.



Finally got to mix up some E85 Castor20 (4part E85 +1part Castor),
strapped a gasproof tank ontop of my plane with some rubberbands,
and ran the ST gs40 on it.
Warmed up on 10% glow regular tank, 13k on 11x5mas without really trying to hard,
then switched the lines to top tank, riched some, and fired up the E85o20:
Top was ok but mid was funky, had to work its way up the rpms,
and even when tuned for a good run high end it was still making like a garden hose of oil out the pipe,
but it hit mid 12k, so that wasnt too bad at all.

It seemed to run better in the air than on the ground,
uhhh, easier to spool up the 11x5 prop???
Should I drop to a smaller prop (back to 10x6) and see if that helps the mid range?

Gonna try less oil next, like 5:1 for a batch of E85o16.
After that will come blending it with some regular glow
