OK, 4 things to do.
1) Replace fried ABC rx with an upgraded Stryker's old electronics
2) Slow Stick wired with Slow-V's remains
3) Lipo-ready T-Hawk (uses a P-51D system) On-off switch is now wired to rx jumper for Lipo/NiMH select
4) Shun Da Accipiter Badius, also Lipo--ready with rx from a stricken Stryker

I'd go 2. I could not see a poor T-hawk get it's electronics ripped out.

I never had the T-Hawk electronics to begin with, but if they really are a lot better than Parkzone's that would be good to know.
BTW, that one was the most work - I had to rework the plastic servo tray to hold the larger Parkzone servos. Messy.
