F86 Sabre, home brewed

I've been admiring Scott Black's F86 for a while now but decided against it as it requires a bungee. I decided I don't like the K&A F86 park flier because of its small size. The only other option is to roll my own.

My F86 will have a 48" WS, about 360 sq.in. wing area. Power will be a Ky T33 fan driven by a HET Typhoon 2W on a 2S2Px2600 LiPo. I'm predicting an AUW of ~42 oz for a wing loading of 16.8 oz/sq.ft.

Like my other EDF's, this F86 will be designed for hand launch, small field flying.

To date I have about 6 hours in drawings, another 4 in ribs and formers.

Since it is summer and the livin' is easy, I probably won't do a whole lot of building everyday so I'm guessing it'll be a slow build. Unless we have a rainy summer.

rotccapt,

My goal is to build a flyable plane, not generate beautiful drawings. Thus my "plans" are the absolute minimum needed to build and there are no instructions. My drawings are a combination of CAD and hand drawn. If I can print a full size component on 8.5 x 11 paper, I use CAD. Otherwise I draw it the old fashioned way.

As I build, I try to revise the drawing to the latest as-built status but sometimes I'll miss a detail here or there. And much is left to the builder' imagination.

I have sold plans to others. The cost is whatever KINKOs charges to copy plus postage, usually around $20. I prefer to sell plans only after the plane has been flown. On my last home grown design (F9F Panther) I supplied two others with the plans before the plane was flown. I did follow up with them concerning the final balance point once I had her dialed in.

Limiting my building time to after 10:00 PM and a rainy/windy Saturday morning, I built the wing panels. Ribs are 1/16" balsa, top and bottom spars are 1/8 x 1/4 spruce, shear webs are 1/16" balsa, LE is 1/2 x 3/4 balsa and the TE's are commercially available 1 1/4 x 1/4. The TE's had to be built up to match the curve of the 12% Clark Y. About 6 hours for the two panels.

I have reached a critical juncture in the F86 build. I am at the point where I need the Kyosho T33 fan so I can mount it into its former. My problem is the T33 fan is still in the T33.

My T33 is a very much flown air frame, full of dings from too many bellyslide landings. Both wings are broken, literally held together with packing tape. The balsa front end is cracked in a few places, the wing mounting plates are loose, again relying on packing tape to hold it together. In short, the T33 is a real mess. But she still flies well.

Taking it apart for the fan is the best thing I can do for it. But this T33 has been a part of my R/C experience since April of 2001. I just can't seem to pull the plug and let it die with dignity.

So until I can canabalize the T33, progress will be slooooow.
