Cockpit attachment
Hi,
After getting the thrust tube installed, and the turbine as well, the next item to install is the fuel tank.
Prior this, I think that the attachment of the cockpit would be a better idea, as once the fuel tank rails are in place,
acces to the location to install a blind nut for the canopy fixation will be come inaccessible.
How did the majority of the JEEMO guys attached their canopy?
Cherio,
Eric

I was finally able to get the Jeemo maidened by the master, Ali Machinchy, at the Bill Beach Classic (Rosewood Indiana)
Ali put the Jeemo through its paces and it was a pleasure to watch.
The Rosewood club has the perfect field setup for the Jeemo, paved runway for the dolly, and a beautiful manicure grass area for landing.
After a couple of flights is was clear that the take off dolly needed a bit of tweaking, it was pulling to the left and the AOA didn't seem right.
So I drilled the front wheel holes a 1/2' lower (Raising the LE of the wing), and added some CF plate material to stiffen the plywood.
After that the dolly tracked straight and the glider lifted off with little effort.
My first flight was a blast! I am really going to enjoy this model.

I just wanted to post an update since the maiden of my Jeemo,
Prior to Ali performing the maiden flight I had the C.G. set to the factory recommended position of 120 mm (4.72") back from the LE using the balance fixture that I made.
When I asked Ali to go over the setup, he picked it up and just held it by hand using his finger as the pivot point, he said to add about 1/3 more weight to the nose.
When he flew it he said the C.G. was prefect for his preference.
I finally had a chance to weigh the total lead ballast in the nose and it is 800 grams (1.76 lbs).
I hung it on my C.G. fixture and it balances at 110 mm (4.33") back from the leading edge.

I have been asked to repost the C.G. Fixture PDF as the one posted early in this thread is not displaying any longer... thank you RCU.
I took the opportunity to update the fixture to show the 110 mm CG point
I tried to upload the PDF and I get a file upload error, once again thank you RCU...
Also AutoCAD.dwg drawings are not allowed, so if you need the file send me a PM with your e-mail.
Zip files are allowed so I tried to upload, that also failed...

Glider-it state a CofG of 120mm with the tank empty. If you're using 110mm with 25% fuel, then what's your CofG with an empty tank...120mm?
Mine flies great at 120mm with an empty tank.

It depends what you have in the nose of the Jeemo.
I have heavier mounting material, a battery box, and two 3700mah batteries. So, I'm using just over 500g of lead, balance is per Glider_it, 120mm with no fuel. Flies really well. For me 110mm with no fuel would be to nose heavy.
