Thanks you guys.
I'm building a 1/4 scale P-51 By Bud Nosen, So far, I have the fuse built up to the L.E of the wing. The tail feathers are complete but not hinged or attached to the fuse. I have made many changes to this kit.
The firewall was changed to 1/4 aircraft ply and moved back to the ply that the L.E. of the wing attaches to. Several conditions prompted me to do this. First, when trying to form the sheeting around the bulkheads ahead of the wing. It seemed that no ammount of wetting and rubber bands would hold the balsa in the compound curve. I tried several times with and without ammonia. I then purchased a fiberglass cowling that extends all the way back to the L.E. of the wing. (also a new canopy, the one from Nosen wasnt all that great.) I have not yet cut the sheeting off ahead of the L.E. and I plan to split the cowl and permantly attach the top half to the fuse. Also I plan to use a 3W 150 in-line twin. (This is the last major expense remaining.) I can build a stand off motor mount for what ever engine I use. When I bought the Tru-Turn spinner I bought back plates for both the 3W and the G-62 The spinner was cut to fit props sizes up to the APC which needs the most room of all the props I have.
When building the horizontal stab, I found that it will not build as the plans say. The sheeting would pull the edges up and would have been bowed if I had not caught it before putting on the top sheet. I added balsa blocks everywhere for Robart pin hinges.
The wing ribs were reinforced and hardwood rails were added for Spring-Air retracts after buying 2 different brands of tailwheel retracts, I ended up building my own. I will post some pics later. thanks again, James
