Good that you have an option for your radio. Wish Tamiya would be like Eduard and give you both so you can choose. I used my Academy SCR-522 on my P-38F a while back.
Added brakelines then both main landing gears and it does sit nicely on the nose gear. Weight is about perfect. I measured both wingtips from the level base (my turntable) and the wings are perfectly level, but for some reason the horizontal tailplane is about 1mm lower on the right side. Not sure how that could happen unless there's a warp in the tail boom somewhere, but the vertical tails are both nice and straight with no twist.
Guess will need some weathering of the gun bay before I add the doors, although they probably kept it pretty clean as the guns and ammo boxes were normally removed quite often. I did do a sludge wash inside the doors though!
Finished a few small things tonight, V antenna was made from EZ line, polyamide tubing for the insulators, and wire and tubing for the attachment to the canopy. I also painted the lights and installed the doors, waiting for them to dry overnight.
