Hello David,
Thank you for the info on the protective wing and tail bags! I'll be looking into them for sure.
By the way, how is your Hunter shaping up?

Only need to set up canopy open/close mechanism and cg. Ran out of motivation last month. Going to finish in next week or two. I want to bring it to JOK. I'm driving the RV out this year. Will you be there?

Yes,
Canopy is jack-screw servo operated.
I’m away from home at this time, I will gladly provide type, stroke length and manufacture for you when I get back.
The actual attachment to the canopy frame is rather critical as I learned, as the forward/aft force will easily bind if not attached correctly.
Be delighted to share that with ya when I get back .

thanks for the reference.
where did you settle on the final CG after further flights?
Hello furloughed!
I've installed a 38 lb thrust turbine and due to its light weight, along with its peripherals, the total weight added right in the most forward (radome-like) area is 4.75 lbs!
I did "not" use their specified C/G of 130 mm beyond the axle center. My starting point was 115 mm, and after four flight on the jet, I've moved it back another 8 mm since. The manufacturers always tend to strive for an extremely conservative forward c/g. And I don't enjoy the resultant pitch-down moments when in an "other" than level flight attitude. I will most likely settle on the 90-100 mm point when time and additional flight work-ups allow.
Feel free to fire off any other inquiries.
Take care,
Franko

After about a dozen flights with new Hunter. I determined that the 105-110 mm CG is perfect!
The fuel burn-down during flight will transition the CG toward the aft point I've listed. The aircraft has absolutely zero bad handling qualities at these points.
The only weak point on this design is the landing gear carbon mounting area's! As delivered, the factory is not generous with the application of their version of HYSOL?
I strongly recommend removal of the flap area to drill HYSOL access points along the trailing edge to ensure a good coating of HYSOL along the gear plate box area's that you can not reach thru the gear areas!
Good luck with your build, it is otherwise a very strong structure.
