Sandy Hogan - continued

Bob reports on the stab: Well not covered but structural. I opted for another smaller but hard balsa spar, instead of half ribs as the wing has, to save weight. LE clamped in place for gluing.
We note that the SH has sub-rudders!

Richard's Stardust Special Finished!

This just in from Richard Dick. He wanted a Stardust Special and certainly did a great job on this one.

In Richard's own words: "I just finished the Star Dust Special and have attached a couple pictures. It is from Bob Holman's plans and  short kit. The wing span is 77.9 inches, 230 mm cord at the center, 660 square inches area, and under camber. The covering for the wing, tail, and fuselage is transparent red and white Ultracote. I think I'll locate the CG at 60% from the LE which is what Dave Harding advises. The power is a Hobby King KDA 36/10 motor and a Hobby King 30 A ESC. This motor has too much power, so I'll need to program a low power setting. I have yet to decide on a battery type - NiMH or NiCd. instead of LiPo - because I'll need to add weights to balance at 60%. A seven cell NiMH 900 mAhr battery pack may do the trick and these batteries are still available. The model weighs 33 oz without a battery."

Sandy Hogan horizontal stab spar

Bob's Sandy Hogan has such a huge horizontal stab, I suggested a sandwich of balsa with a "filling" of carbon fiber tow.
Bob writes: "I made the Hogan's horizontal stab lower main spar per your suggestion. It works great. It will not bust or break! The Dave Brown carbon strip excellent."

Here's a photo Bob sent with a teeny sample of his lay-up.

Sandy Hogan wing

Bob Galler reports on his BIG Sandy Hogan project:
"Here are a couple of photos. The heart and soul is done accurately. I now go in a two-prong attack. Finish the wings in hobby room, and the stab in the garage! Lots of lumber, and epoxy. "(Editor's Note: When you see the size of the model Bob is building you will understand why he needs two building sites!)
