Tried that once. We spontaneously decided my brother's "Grasshopper" RC car
could use `D' power, so we found an old body shell, glued bits of wood
longways on it which the motor sat between, and taped it in place (it was
only meant to be used once !). Didn't try R/C ignition, but used my Estes
launch controller. He accelerated the car, and after a second I pushed the
button. I was too slow, and the igniter leads were yanked off the motor
too quickly. Tried again, and I pushed the button a little earlier.
Ignition ! I've never seen an R/C car move so quickly in my life. It was on
a less-than-even concrete path, but he kept it under control and wheels-down!
Probably because, and you may want to bear these suggestions in mind:
1) The car was a fully equipped RC car, and therefore quite heavy in relation
to both motor and thrust (the initial thrust spike of the `D' still gave it
a decent kick though)
2) The motor exhaust was slightly upwards as well as horizontal, thus helping
to pin the car down onto the `road'.
Best of luck - please report results !
