Hello Ravill,

Not yet, I'm waiting for a new clear bubble of the canopy, I was detailing the Canopy and when I tried to clean the excess of paint with acetone the clear bubble started to deform, so I tried to apply heat to correct it and it got worst, so I ordered a new one, and I’m just waiting for it to arrive
to install it, other than that the A10 is ready to maiden.

Wow! I would never have thought that a little acetone would hurt the canopy that much. I'll have to make a mental note to not use acetone on canopies! I hope you get a replacement soon.

For lighting, I used unilight. I like their 8 channel controller and I went nuts with lights. I even have some special extra stuff. More on that later.

All that's left is to do some engine runs, clean up the install, install the cockpit and pilot and then balance!

And this is not a small airplane either. It is difficult to manhandle this thing around. I find that I am always putting too much pressure on the engine nacelles, then the slats, the gear doors,etc.... I can't imagine what it would be like moving a Mibo around for assembly!

Ok, it's official, I needed 8oz (1/2 pound, <1/4 kg) of lead to balance! That's the lowest I've heard of yet, nice! I balanced with dry tanks, full UAT, gear down and on the rear most measure from SM (110mm back from the wing root).

What are people feeling like with the throws suggested by SM?

Here are my control throws:

Aileron = 1” up, .75” down at root

Elevator = 1” up, .75” down at root (neutral position at blister)

Rudder = .625” either direction at base (max I could get with hidden mini digital servos)

Flaps = 1.5” landing full flaps
