Default "Home of the Brave" 1:3 scale 100cc that is

We are going to change our slogan to "Home of the Brave" since I have been goaded into producing a 1/3 scale quick-build all-CNC EPP flying surfaces and all machined and laser cut quick-build birch ply kit for the 100cc class engines. It should be awesome with our BME110 XTREME swinging a big 26x12 3-bladed prop.

After the Pawnee, we decided it would have to be scale and would have to be the Brave and so the PA-36 it is. It lends itself better to the quick-build format due to the fact that it has no wing struts, sports slab fuselage sides and straight or beveled simple wing and tail tips. The base kit will be able to be assembled ready for covering in two days, simply tabbing the fuselage bulkheads to the sides after glueing on top and bottom inside stringers, then clamping and glueing. Turtledeck and front deck bulkhead are then placed and both sheeted. The front deck will be completely removable for radio, electronics and battery and fuel access.

Next edge-glue up the balsa sheeting supplied in the kit to match the templates provided on the plans and glue up the cores for vertical, horizontal and wings and put them back in the shucks, glue and sandwich and weight the cores to cure for final trimming and leading edge installation. Tails will have airfoil profiles for better performance and cut with the same precision as the wing. The wing core will have relief cuts factory made for hinge clearance and all that will have to be done to hinge them after sheeting is to flip the flaps over for bottom hinge and leave the ailerons as cut for top hinging.

The spar system as it as planned will be a lamination of laser cut carbon fiber and aircraft plywood to create a removable spar and sleeve joiner system which will accomodate the dihedral and allow a robust airframe to tow 40lb gliders or be loaded with 25 lbs of insecticide and go spray the back forty.

We already have three views coming from Piper and major components sourced such as superior quality cores from our supplier flyingfoam.com in Riverside CA and high quality .25" 6061 T6 aluminum landing struts from Abell RC in Billings MT.

Prototype build to begin 1 Jan for Feb/Mar kit shipping. Just in time for next year's aerotow season. Tim Wieber at Ionia says he will be taking his Pawnee along with Dick Graham's original to the JR aerotow next year, and with any luck, he will be bringing the Brave too.
