Oh no, another of those crazy Fiero owners?

"Crazy Fiero owner" is redundant, btw
The problem I have with the load/unload -- besides, yeah, the weeks of designing them and having to recall high school trigonometry! -- is actually doing it. It's just two dials on the TX, but for some reason I can only do it while looking from the left. If I'm on the right-hand side of the truck the dials are "wrong" in my head.
I've found it best to move the hook up as the A-frame goes up, then down while still moving the frame up, then the hook goes back up again, to get a nice smooth movement without tipping the load at too great an angle. Harder than it looks, and gives you respect for the folks who do this on 1:1's.
I took some video early on, with the parts in place but before paint and with crazy messy wiring:

You can see sometimes I move the hook up when I meant to move it down; when the arm is down, twisting the hook dial one way moves the hook "up", but once the arm is up, twisting the hook dial that same direction moves the hook "down". I think even if I changed the dials out for momentary switches I'd have the same problem, as for some parts of the arc pushing the switch "up" would move the hook "down." Ow, my head
After the truck was finished I did some more videos. Here's picking up the flat rack, with the Cross RC truck tied down:

and driving around loaded

eagle-eyed viewers may notice one of the front marker and turn sets is munged in this video.

The outrigger feet in the back aren't just for looks. Even with the pool noodle tire foams, the weight and force of loading anything really pushes the back end down.
Sorry for the crappy video, apparently it was dark in the garage. Outside looks a little better

Leftover gravel, river rock and roof shingles from various house projects can become a playground with a little effort. The bridge is a broken-down pallet (remember Bridge Over The River Kwai? This is Bridge Over The Railroad Tie.)
