I am working on a first Generation P-38 from KMP.

As with all of my planes I have to nearly rebuild everything,
this one notwithstanding.
The kit is very nice and I have read and seen a video that they do fly well.
I plan on using 2 OS 70 4 strokes.
Robart 600 series retracts and repainting the whole plane like YIPPEE

Now that the new generation is out of the P-38 line , I could have waited 6 months and bought one ready to go.
Oh well nothing to change !
I think that the YS engine would be fine, probably even turn 3 blade props.
