RE: Hangar 9 Pawnee 80"
Hey OldScalGuy, glad I could help you land a Pawnee. (No Punn intended)! Mike said he has already had a couple of guys come into his shop looking for one since he sent yours. Our club had our annual Mall show last weekend and my Pawnee was the talk of everyone. All my fellow club members were drueling over it. Let us know when you get it going.

RE: Hangar 9 Pawnee 80"
I've not flown mine yet. Still have to finish the radio installation. I put an FA-90T Saito twin cylinder in mine and so is TooLow as we have been discussing earlier in this thread. I know they call this a 40 class airplane, but at 9 lbs. + and 80 inch wing span, Personnaly I don't think a .91 is far off the mark. Had I not been able to fit the .90 twin in it, I was going to use an .82 saito that I also have. I'm sure a .72 would fly it on the lower threshold of scale, but I prefer a little reserve power to get me out of a tight spot such as a botched crosswind takeoff or landing. It's ironic that due to the intigrated mounting plate on the twinn, the box was actually too short and had to be provided with a 5/8 inch spacer block and the single mount makes it way to long. Anyway, just my thoughts for what they're worth. Enough power is good, but too much power is recommended!!

RE: Hangar 9 Pawnee 80"
I had a 1 inch thick nylon block that I band sawed down to fit the engine base and re-sawed it down to 5/8 in. thick. Then I sawed out the center to leave a 1/2 in. all the way around. I left more in the corners to reinforce the bolt holes and drilled it to match the holes in the engine base. It just did fit the engine box with no room to spare. I barly had enough room to get nuts and washers on the bolts because they were so close to the edge. There was not enough room for blind nuts so I used small washers and lock nuts. The good news is, there is plenty of room inside the fuse and box to reach in and start the nuts with a nut driver. I think I am going to reinforce the box by glueing wooden gussets to the outside of the box and firewall. The only thing that I worry about is the small washers and lock nuts eventually wallowing into the wood. I may change that and grind off one side of the blind nuts so they will fit up close to the top and bottom of the box. Any thoughts?

RE: Hangar 9 Pawnee 80"
Actually, the needle valve knobs stick up above the cowling. But I have another hair brained idea!! Alot of the full scale planes are equiped with a GPS guidence display out on the hood to help them fly the grid while spraying. They look like a rectangular box with LED's that line them up on each pass. This just might be the perfect cover-up for the needles. Hmm, I'll have to give that one some thought. I agree with you Oldscaleguy, I wouldn't paint the rocker box's. That little bit of chrome showing looks goooood. By the way, my LHS still has one in stock. He ordered two when he ordered mine at the end of January. If you're interested let me know as I'm sure he would be glad to ship it to you for S&H.

RE: Hangar 9 Pawnee 80"
Yea I know. I mis-measured on my first hole so I ended up just connecting them together. Don't look bad though. Food for thought, if you drill individual holes, you'll have to make them a little oversize to access the low speed needle valves. Also flex tubing works perfect for the exhaust and just fits under the flare between the bottom of the cowling and the fuse.

RE: Hangar 9 Pawnee 80"
Well, I held my breath and took the plunge. I figured the worse that could happen is order a replacement cowling. It fits nicely with minimal cutting for the rocker boxes and a 2 inch wide X 1/2 inch slot in the top of the cowl for the twin carb needles. TooLow, my engine is also an older FA90T, looks just like yours. Although, it's never seen fuel. Now I'm really exited!! I don't intend to wring out a crop duster doing 3D or anything, but I want to have enough power to pull out of a "uh-oh" if I need to. As big as the Pawnee is, (big to be considered a 40), I think the twinn 90 will be perfect. And the sound should be sooo sweet! I'll post some pics next time.

RE: Hangar 9 Pawnee 80"
Got my Pawnee last Wednesday. Wow, It's every bit as nice as I thought it was going o be. I know Hanger 9 suggests an .82 for a four stroke but Im trying something a little bigger. I had a Saito .90 twin cylinder that I've been dying to put on something. It's heavier for sure but fits nicely in the large cowling. I hope I can overcome the extra weight in the nose by battery placement (using a sub-c receiver pack as far back as I can find a place for it) and maybe a little added lead weight behind the cockpit. My motto is enough power is good, but too much power is recommended!! Anybody got any thoughts or suggestions about this set up.?
