Also note that the firewall is constructed in two p ieces=2C which allows removing the lower section for access to the front ru dder pedals and other things in the front cockpit. Just don't do what I di d and forget that the lower engine mount points bolt through the firewall a nd trap the section of firewall that is supposed to be removable =3Bo) No ashtrays in 41CC but the front cockpit has an outside air temp gauge.

If you have your fuel tank up in the front =2C make sure you route any cables=2C controls=2C and wiring close enough t o the fuselage sides to get them past the fuel tank. Working up in the wid e-open front area without the fuel tank installed=2C I thought I had a huge luxurious open space available to route wires and cables to the engine com partment=2C forgetting about the fuel tank. Tach cables in particular do not like to flex sharply.

The tach cable has to offset=2C as you can see from the photo taken directly above my firewall=2C you can see the amount of offset that could b e avoided. Photo at http://www.flysquirrel.net/piets/repairs/P310002.JPG Actually=2C if I were to install a tube through the tank I think I'd put it an angle =3Bo) My tach cable is stretched to its max limits and I really need to get a longer one=2C but it would have to be a custom length. I thi nk mine is a standard 48" long one and 60" is too long so I'd need a custom one.

Altitude wasn't any problem but fuel consumption was. That is a 145 plus HP Warner, when it was installed I never changed wing position, and it weighted 50 lbs more than my Ford. Flew strong and fast.

As long as the numbers are going to be a generic color, like white or black, I see no reason why not. The spray can numbers have been on my Travel Air rudder for nearly twenty years (cotton and dope) and is still as flexible as the day I painted it. No cracking or peeling. I have done this on a number of fabric aircraft with both dope and poly spray and never had a problem. Gene ----- Original Message ----- From: Douwe Blumberg To: pietenpolgroup Sent: Friday, April 24, 2009 6:35 PM Subject: Pietenpol-List: painting small numbers > Hey, I'm using dope on my plane and was wondering if I can use enamel for the small tail numbers. I know it'll stick fine, but I'm wondering if it'll flake off over time or is it pliable enough to use there. I know sign painters enamel works, I'm wondering about randolf enamel.

I used to find it at a stationery shop in sheets something like 24x30, and when taped together with packing tape, could be made into large patterns without folding on the joints. Now, can I find the stuff around Falls Church where I live now? H#^L NO!
