Looks like the wing came in at 7.8 #s and the total plane has weighed in at 23.7 #s. The gear actually weighs 3 #s so they are a little heavier. I also have a removable air scoop. I did move the engine forward 3/16" and also repositioned the three batteries vertically up against the inside firewall, so now I was able to remove .9 #s of lead weight from the nose. To help the balance, I also went with a smaller servo in the tail for the tail wheel.
May not get to fly the plane until next week do to a scheduled event this Friday - Sunday, and all the week day competition practice.

I was running my P-51 tonight and the Tony Howard exhaust stack rattled loose. I used 30 min epoxy and 2 screws to secure it as recommended by the instructions. I am thinking about trying Hysol 9462 but don't really want to buy the whole applicator kit for $62 at this time. Has anyone used this stuff? Can I mix it like regular epoxy and apply to the shroud or do I need that expensive applicator/kit?

Yes, I lay out on a plastic lid, mix with a mixing stick and apply.

Hysol is great stuff, but I do use the applicator. I know that some have make up a double dowel glued/screwed to a piece of plywood and push the mixture out on to wax paper and then mix it by hand. looks like it is equal amounts to mix, and it will harden over night. When I am finished, I take the nozzles and push air through them with the compressor and then clean them with acetone so I can reuse them, that seems to work fine.

Down to the fine points now on the 51. Gear was catching the scissors link against the back of the wheel well. I had hoped to not cut an opening in the glass for the air cylinder but I had to open it so I could push the wall back far enough to allow the link to pass. I elected to make the area over the cylinder removable so I expanded the wheel well cover to handle this. The wheel well fiberglass is not really held very well in this area, so I put in some hardwood strips so I can screw the wheel well cover in position. It also allows me to get to the air lines and cylinder for inspection. Photos shows attach points and then the paper templates. Tomorrow I'll cut the 1/16 ply, cover them and screw them in.
