Good to know, figured that they don't have the "pinch" that Nitros have, so warm up and break-in isn't as critical.
Second start I let it warm up one or two minutes, then did some running with it. It got up and went, but think I only did one pass that briefly hit full throttle, then it was like the clutch went out?... No crashes, no jumps. Something in the left-side hub/drive broke/loosened (shaft doesn't turn with the wheel, RHS OK), but I haven't disassembled it, yet.
I'd heard that I should dis-assemble, then re-assemble this using loc-tite, so we'll see. I would have liked it better if I could have run full-tank of fuel before I had to put a wrench to it?...
