Hey guys,
Background! I've done about 10 or so Stampedes previously, about half of which had the BT kit. However, today I came across a problem that has me stumped.
The problem:
4 x Ultrafire 14500's, fully charged providing >16v
Motor and gearbox spin fine with no plunger/breech assembly
When I manually cycle the plunger/breech assembly, everything works. The catch catches, and the release bar triggers when the plunger tube is all the way forward and releases the plunger. All as it should be.
Yet when I try to drive the plunger/breech assembly with the motor; the catch works but the plunger tube stops ~15mm short of the catch release bar. Say exactly like it does if you don't have enough power to compress the spring. Yet, I have >16v and I know from my other BT kitted Stampedes that they'll normally work down to about 12v.
Short of 'BT gave me an OP spring', any ideas?
