Wheel Hex pins or pinion not tightened on motor shaft flat or no flat spot at all.

I'm new to this and stumped.
Just built my kit.....brand new, drove it down driveway 3 feet and it barely moved. Pull trigger...motor spins....that spins center diff very fast......front and rear dog bones spin up......vehicle barely moves. Lift car up in air and pull trigger and the wheels pretty much balloon up.
I noticed if I lift either the front or the rear end....hand turn a wheel, the opposite wheel doesn't move at all.
Center diff has been out and reassembled, it's full of oil.
Any ideas please? Thank you!

something like this has happened to me. with no load (wheels off the ground) everything seems in order but as soon as you set it down it just crawls making a loud noise... turns out the problem was with my motor - the shaft had delaminated from the rotor. try installing another motor and see if it solves the problem.
my spring perches keep coming off!
the cup on the shock end!
To keep the spring perch on the rod end! I ran a q and a Main with both front spring perches off! I was gonna super glue but shouldn't have to
I'll post pics tonight
for my ride height, springs aren't that tight or under compression! Yes springs are broken in! I use the HB Gold front and Yellow rear springs
If I remember correctly my ride height is 20mm F and R

There shouldn't be any way to make the car just not move if all three diffs are built and installed correctly, even with 1K oil.

That just isn't how a diff works. Lighter weight oil will allow one side of the diff to spin faster than the other side more easily. Especially if traction is low or one wheel is lifted while cornering.

Think of it this way, during hard acceleration you want max traction at all wheels especially the rear but as the car pitches back the front wheels get light and unload. Diffs like to transfer power to the path of least resistance, this case being the lighter front wheels as they now spin free and the rear that has the most traction isn't getting the power they can handle. The heavier oils limit/slow the power unloading to the tires with the least traction.

If you're absolutely sure the wheels all turn the same way when you pick it up, I'm gonna have to go with the suggestions about missing pins, or missing washers behind the spiders and/or sun gears. A bad motor shouldn't cause the front and rear drive shafts to spin, as described.
