That's exactly what I'll need if I ever decide to add some range with wing tanks. A 60" long tube 6" in diameter would give me over 7 gallons, all of which would be usable.

Also Dan Heath had me use a spacer between the bell crank arm and the pushrod, making the pushrod able to apply force in a straight line to the aileron tab. You might also need to drill 1/4 to 1/2" closer to the hinges on the aileron tab so that more throw is achieved with same stick movement.

I don't know which book you are referring to, but that doesn't apply to when you put fiberglass on top of foam. In that case, you NEED to squeegee a runny slurry mixture of epoxy and micro into the pores of the foam to avoid putting pure epoxy in there. The micro helps lighten the mixture considerably, probably by about 3/4. The tensile strength of foam is so low that the micro/epoxy slurry is still way stronger, so it's not a problem in this case, but a benefit. The case where you DON'T want micro under the fiberglass is over the spars or some other structural location where the connection between the structural member and the glass is critical. Page 8 of my 1990 KR-2 manual details the use of "micro slurry" over foam, and there is mention of the critical spar connections on page 50, as well as other places. If you put fiberglass over foam without first squeegeeing in SOMETHING, the fiberglass will not stay attached to the foam for long...

By 9 this AM I had added the fuel pump and this regulator type device( It seems that restricts the flow of fuel, as opposed to controlling pressure). I ran the engine and for the first time I knew that I was running rich at WOT. In fact so rich that the engine tried to quit. I found that when the pump is on, I did not get an anticipated flood of fuel. The engine seemed normal till I reached the part where I had carved a step in the needle. At that point, the engine flooded. After several trial settings, I installed the last needle that I got from Joe at Revmaster. To get the best run, I would start with the fuel off and after a warm up I would push the throttle to WOT and turn on the pump. But, the real question is what about the temp. I made a 3 minute run at WOT, controlling the flooding by moving the mixture control. I was able to hold the temp of #3 to 450. The engine was turning 3000 and 30 MP. This is the first time that I was able to see the effects of the fuel cooling the cylinder. This is still not too Kool. I need to cool the thing down at least another 50 degrees. I can live with 400 CHT on takeoff. All the time that I have had the CHT gauge in the cockpit, and I don't remember what the takeoff numbers were on the old engine. What are some of the takeoff numbers that other get?

I remember that I was told that because of the gravity in manuvers that you could run the risk of fuel starvation. Well, I tend not to think that way what with the baffleing and that mesh-net that can be put into the tank. I think that the Grumman AA1 had baffles in the tank. And, the new extended range tanks for the AA1 are 8" dia. agri irrigation pipes. I just think that the whole conversation about the use of auto gas would come to a hualt with the use of the pipes as fuel tanks. And it sure seems that with baffleing, the starvation would be cured.

On an 85-90 degree day, I will take off and CHT will climb to 400-425 depending on the altitude I'm climbing too. I never exceed 450 and if it is going over 425 I will lower the nose to get more air through the engine cowl or if it is a 100 degree day, I have actually climbed a thousand or 1500 ft and leveled off to cool it and then climb again. This is especially true when I have someone else on board and I don't have the option of pulling back on power. Anyway those are about my numbers. I don't think anyone has discussed this yet but I'll bet Mark can chime in here. If you have a bigger engine and didn't create a larger exit for the hot air, you could also simply be choking off the exit air. I seem to remember, but again someone else chime in, the exit area needs to be about 4 times the intake hole size. That seems big but my books are at the airport. Cooling and timing are critical but so are the cooling hole sizes. Of course another discussion will be the larger the size the more drag but that is another item with a different fix.
