Not to sidetrack the thread but here's some added info ... I got to thinking:
That characteristic has to do where the main gear footprint is relative to the CG. Every RC version of the F-4 that's worth building/flying has its main gear in the scale location. (There's really no place else to put it.)
Most know that for sweet handling both off of and on to the runway, the relation of a trike gear's foot print to the CG likes to be at an angle of ~15 deg. But the full size and RC size birds end up with the CG in totally different locations. And with the model, because it's happier with a more forward CG location, that ends up pushing the wheels aft of the dynamic CG. That's why the increased AOA (and lots of scoots) from the extended nose strut often helps in more predictable/smoother rotation. Just the opposite on recovery - once that bad boy hits the tarmac it will remain stuck. You can see the compression of the nose oleo in one of the still photos.

Gawd, what a gorgeous jet. (the short nose version flown by the MARINES' Warlords/VMFA-451 is my favorite) Anyway, excuse me I've got this giant woody; I gotta go to the bathroom.
