I CG’d last night. Looks like I needed just under 1 lb of lead to balance!
And I used Craig’s technique. It was rather easy!
I made a little stand that sits about 1 inch taller than the jet, made some plywood wing plates marked and slotted so that the stand would key into place.
All I had to do was lift the nose and rest the Hog on the stand which keyed in place on the taped plywood wing stops. No help needed and quite simple!!

Ok, maiden report is in!!
The pluses:
This jet flies like it’s on rails. It is a big, graceful, pattern plane.
I am a elevator believer, so I was able to dial in 10 mm more than the recommended travel for the elevator. In short, that was too hot. Like you all have stated, the stock recommendations are quite nice. The ailerons (at 30mm) were ppppuuurrfect.
On my second flight I was able to get my A-10 nice and close to me so I could see my awesome paint job! When it was farther away, it actually looked like a grey A-10! We were surprised!
She lands nice, slow and sweeeett.
The bad:
My main gear twisted to a 30-40 degree toe out on my first touch down. It made for a VERY short roll out after touching down.
This, unfortunately, broke the two little gear doors on the mains. I also found the the set screws were all loose on my mains.
Also of note, there were no flat spots for the set screws.
It took me a few hours to get access to the set screws and fix the gear doors. I was unable to disassemble the gear to put some flat spots in, so I decided to just REALLY tighten the set screws and go for a flight.
This is when I noticed that my nose gear axle looked bent. Well, the axle was loose. So I tightened the axle and found that the nose strut bottom is a composite piece and there was a small crack. I was able to tighten the axle and I went for my second flight.
On my second flight, I wanted to extend my final approach 50-75 ft, so I touched my throttle slowly with up elevator as an anticipation, and that is when I noted that the engines REALLY push down the airplane at slow speeds.
My main gear twisted again, though notably less, and my nose axle crack looked a little worse, so I called it a day.
Like this awesome jet has proved before, it is a Sswwweeet flier. My gear disappointed me. I did not see that coming. Obvi, I will be working on that.

Congrats Raffy, welcome to the club! You are just not supposed to tell everyone how easy this jet is to fly.
Sorry about the landing gear. I went through similar teething issues with the earlier versions I had but once sorted out, have had many, many incident-free flights.

Thank you everyone!!
I missed you there Carlos!
In retrospect, I kind of remember Oli mentioning that the gear isn’t tightened for easy(ier) painting. As I didn’t have to disassemble my gear I didn’t notice some loose set screws? Oh well, I’ll have to sort all that out.
I wanted to dial in the demon Cortex and then start the gun and wingtip smoke! That’ll have to wait!

Rav,
Congrats for the maiden
Only the grub screws won't keep the main gear from rotating. You have to take the part out and glue it with red loctite, otherwise will happen again
Main gear is an easy one to solve. Sad to see such a nice engineered kit having such a poor landing gear

And on to the mains.
It is a catastrophe that there is only one flat spot on the whole system. The flat spot is on the steel piece between the trunion and the strut. There are 2 set screws at 45 degrees and they have no flat spots. Neither do the set screws ANYWHERE else.
If you have a Mibo A-10, you NEED to add flat spots and thread locker everywhere.
I put in 2 , 8/32” set screws on each main and added 4 flat spots to the bottom piece that rotated on me.
On the top part, I had to dremel 2 more flat spots.

Congrats on the maiden Rav !
I'm about to start working on my LG, thanks a lot for the tips and advices. One question, I will start painting the LG legs and strut covers, do you know if you can remove the LG legs without dismounting the whole gear ?
Or do we need to remove the whole behotec unit ?

Thanks Jim!
The whole strut with cover and all comes off with the loosening of the two lowest set screws on the trunion of the retract. The retract body can stay mounted to the wing.
The steel pin that sticks out of the strut is the only piece with a flat spot. That steel pin comes out of the strut with two set screws that are at 45 degrees off of the middle. There are NO flat spots here or anywhere else. This is also true for the main axles.
