ps captain shush up or you'll have sr batting on about cdi for months

Of course first things first, i have to actually buy the plane when its available. Already have $100 down on it. Then I have to find a bedsheet to cover it with, maybe two of them. Its a big sucker.
My FA-300TTDP (dual carbs) uses 1.5 oz of 15% nitro Cool Power per minute @ WOT W/CDI. That's no worse than n FA-150 on GI.
Eliminate the nitro & reduce the lube & you would see even better fuel economy. Rather than converting an FG-57 to methanol, I would convert an FA-300T to CDI. If you still want to go FG to methanol, opt for the FG-61 that has the same stroke as the FG-57 W/a larger 37.2" mm bore & adapt the 12 mm FG-220 Big Bore carburetor. That should make at least 6 HP.
