Nice work Kyle and welcome to the ZP-38 club. Don't get in too a big hurry getting this plane into the air. This p-38 is a proven design and they fly very well. I first started flying my "California cutie" back in 2003 and have somewhere between 150-200 flights on mine.
It looks like you are using g62s for engines, good choice. I first started flying mine on g45 and they performed great but left me wanting more power on those hot and humid days. I converted them to DL50s about 6 years ago and am considering on going with 60s this winter.
Are you going with the stock magneto's or did you convert them over to electronic ignition?
Don't bother with the Twin Sync. I had one on mine and they caused more problems on mine than cured. In about 30-40 flights I had with with the twin sync I had a few pull backs to idle happen on good running engines ( to reset you would pull the throttle stick back to idle and this would disable the twin sync and you could bring the power back up).
I also had some serious damage occur when I lost throttle control and could not bring the the engine power down to land. I was not able to kill the engines in flight ended up having to fly her into some tall grass at almost full power to get her down.
When the plane was rebuilt the twin sync operated normally but the problem resurfaced while testing on the ground and the cause was a bad pin connection between the micro chip and the socket on the board. With another recent power pull back I have since pulled the unit out.
Here is a couple pics of my Cutie and the new paint scheme as Bobcat II.
I will take some pics and post to show you how I did some things on the set up of my plane.
