I have a full build log on the flitetest forums. It's all free software. Linuxcnc for CAM and a website for generating the wing gcode. Depending upon n parts already on hand it's in the $200-300 range.

Decided to make this a slope soarer.
Making a guess here on what final weight will be based off removing power setup:
3.5-4kg
Wing area is around 1,200 sq inches
Wing loading probably 16-18oz
Cubic wing loading would be 5-6.5
MH32 airfoil.
Going to have it ready for Sunset 2019

Well done!
Your F100 was the show stopper at this years Sunset Beach Camp and Fly!
I was impressed that she flew so well. I think you said this started out as an electric build. Most conversions to PSS don’t turn out well as they often have way too draggy an airfoil. I think you said you used the slippery MH32. This airfoil was originally designed as a racing airfoil. It makes a very good glider airfoil. You used it to good effect. This type of ship is all about the reduction of drag. Might I suggest going with top drive ailerons. This should add a bit more durability to an already durable airframe. I’ve found that the bushes really like to pull on the bottom linkages as we land on them!
I was surprised to learn how much drag the linkages produce.
https://www.mh-aerotools.de/airfoils/index.htm Look under aerodynamic.
I noticed that your F100 showed the classic swept wing turn phenomenon (tuck and roll) if slowed down a bit too much in the turn. This is just a characteristic of the swept wing.
Again well done! I have to admit I didn’t think she would fly near as well as she did.
All the best,
Konrad

I think i can lighten up the f-100 a bunch. flight number 2 i moved the 2200mah 3s pack back about 6 inches and flight number 3 i moved it about another 6 inches and it was still nose heavy with a bunch of up elevator dialed in. I would remove the trim and use the radio to offset it each time, but each flight i was still running out of trim and having to hold back. The canopy is a huge chunk of foam, plastic and tape, i can convert that to hollow fiberglass. I could probably remove all the nose lead weight and go to a smaller battery.
