Wrongway rc has a 2 line 11+ oz. and a 3 line 16 0z tank. I was thinking I would prefer the 3 line system, but 16 oz seems like that may be a lot of fuel for a 20 cc gas engine. I'm sure there is no issue in the size, because the Four Star 120 manual recommendes a 16-20 oz tank. Does anyone have an opinion on this matter. Also as far as gas is concerned, I have a gas station near my home that sells non ethonal higher octane premium gas. This is all I ever use on all my small engines. Chain saws, garden tractors, lawn mowers & more. I plan on using this also for VVRC engine. I assume this will be fine.

Lamar, the non-ethanol gas is fine in the VVRC engine. I use avgas in all of my gas engines which is also non-ethanol material, and it works great in the VVRC 40 twin.
On gas tanks, you can build your own from a Fiji water bottle. They come in 330cc (about 11ozs), 500 cc (about 17 ozs) and 1000cc (about 33 oz.). If you need fittings and gas line, I carry both. Contact me directly.
Regards to size, I use the 330cc for my 30-40 cc engines. I tend to run at 2/3rds throttle in my flying so the 330 cc tank last about 20 minutes. I recently got the OS 15 cc and I use an 8.5 oz (250cc) Dasani water bottle (round) which lasts about 12 minutes at WOT.
