It is 11:30 and I am back from the shop today I worked more than the usual I stayed from 9:45 to 11:30 a whole 2 hours. I only work after we put Alex to bed  Z@@ZZZ Z@@ZZZ.
So far I am putting the final finish on the wing and fuse molds. Also I am sanding the flaps and top fuse structure molds whitch are made of aluminum. It is a lot of work and not much time. I am sure it could fly in a month or two. I think I have zeroed in on the Sultan setup for power with the addition of a cooling fan on the motor.

I have been busy with another project and now I am ready to start pecking at his project.
Adventures in balsa forming
Well I started to form the balsa in the vaccum bag but I believe you nee a bit of heat to dry it in vaccum so I ended up with the piece formed but not dried. OK back to plan B. I put a napkin on top of it and on the top of the napkin I put some sh...... ,well it is not sh.... it is sand, to hold it down in place I hop it is dry tomorrow.

Hi Dorin,
I am confused. Freeze drying works in exactly this way.
Can you pull a hard enough vacuum on the wood to evaporate the water or will the wood crush?
Now I have to go look up the vapor pressure of water at room temp.
Dean

Found it.
0.025 atmospheres should do at room temp. Does wood crush there?
0.05 atmospheres will do at 100 F with some margin.
I have no idea at what pressure balsa crushes into junk.

Regards,
