For the CZAW tanks that works out about 40 litres / side with 2.5 litres undrainable - total rating for these tanks was 85 litres. As with most aircraft, Cessna 150 for example, there must be an additional amount of fuel available to slosh about and still maintain safe flight and the proper term for this may well be 'unuseable fuel' For the CZAW tanks I rate that amount as 10 litres / side. I have at times unported a tank with 15 litres when in a steep descent, resulting in power loss of 10 - 30 seconds, so the problem is real. I have not had any problems in level or climbing flight but the drill is to feed off a better tank or both if the level is low.

The parts are to spec per the plans. Just off the top of my head, I'd say I've used about 7 sheets of 4 x 12 6061-T6 in various thinknesses. A sheet from Aircraft spruce is about $90.

I chose the Lyc because I happened to have one on hand along with a McCaully prop. Other wise my next choice would be the Corvair first, the Jab 3300 next, then the Cont O-200. My engine/prop (O235 C2C and 71/54) came from a Grumman American AA-1, so that will make the test program simpler. I may re-engine later. The engine has a good reputation. The O-235 was certified in 1940. The 235 C2C has a 6.75:1 compression ratio and has a 2400 HR TBO. The latest Lyc Operators Manual gives the weight as 244 with the old heavy starter and generator. Rated power is 115 at 2800. Grumman American dialed it back to 108/2600 for noise certification. No Max Continuos Power (MCP) listed. Only 5 minute limits are for CHT. It will run on cheap booze (for a little while). Some XL builders are using the O-290 at about the same size & weight. The 601 will do better than a GA AA-1 because it has 3 feet more span, more wing area and has a 200lb lighter empty weight. Never flown one. To compare apples to oranges, see FAA home page and look up Type Certificate Data Sheet (TCDS) "A11EA" for the AA1. Also compare at: http://www.grumman.net/cgrcc/aa1compare.html They kind of look alike from a distance.
