a lot better on the ground, no more desire to ground loop on take off or nose over after landing.

a lot more stable and plane still looks good, more flyable, less scale.

all the ribs are the same, I used some of the leftover originals as a pattern, spars are cut from poplar from Lowes.

Micro Mark table saw is my friend, also allowing me to use scraps for stuff like cap strips and stringers.

first side being built. The plans show this with solid 1/8" sheet, I decided to save some weight and just use an open structure similar to several of the other 1/4 scale kits I have done. I did adjust the firewall position for G62 engine, about 1/2" shorter than plans.

I found a bonus here. as I was going flying I ran across some landing gear that a friend had given me. It came from a Top Flite Stinson kit that he put TNT gear on. It is a perfect match to the plans, Hope I never need it for my Stinson because it is gone now...

Up on wheels, the square tube is to check the level on the wing. The top has the cabane mounting plate setting in place to get some interior bracing. the gussets can be seen in the open structure.

the cabanes are mounted to a box that is set into the top of the fuselage sides. I glued some blocks on the side of this to hold it's position as I worked on it. this will be glued in place later to set the alignment of the top wing. the firewall is not glued in yet either.

a few clamps hold everything in place so I can wire together and solder.

wires are soldered, incidence is set at this point. firewall is glued in place. cabane box is still removable. The brass tube will hold the top wing on. It pulls out to remove wing

firewall has a beveled plywood spacer to set 2 deg right thrust. the plans did not have this but experience tells me it's a good idea

This center rib is a sandwich of ply and balsa with a brass tube thru the center that aligns and attaches the top wing. The inner tube gets a threaded rod glued into it with a nut to hold the top wing on. incidence and front to back alignment are double checked and cabanes are epoxied in their hardwood mounting blocks. the whole box will be epoxied when the wings are on just to double check alignment.

fin and rudder framed up, outside edge is strips laminated together, corner bracing and hinge reinforcements will be added later. A lot lighter than solid sheet.

I also got the cowl and wheel pants from Fiberglass Specialties. They are for the Hostetler Skybolt. The cowl will need to be trimmed back about 1" to fit as it is too long
