Here's the scoop.
1. I took my vehicle out for pre-run.
2. The glow plug popped out of the head button. Everything is fine (happened before on my original OS 25)....turns out the T-Wrench was stripped when I put a new one on.
3. Took it back, changed plugs...drove it ~1/2 tank.
4. Tried another plug, started it up....squeezed throttle....it went in reverse. What is on film is pretty much as much I ran it as (as soon as I noticed I grabbed my camera).
5. I Google'd it, and, seen it's happend to a few folks. Well...here is what it's not:
- "Set your reverse switch on Transmitter" (BTW--the reverse setting is in the servo...not transmitter). Regardless, the linkage does not affect the direction it runs. ;-(
- "Check your OWB" (this was a popular response in some instances probably cause....but er, this engine doesn't have a OWB.
So...here is all I can conclude:
1. It HAD to have started in reverse. I don't see what would prevent and engine from doing that.
2. So SOMETHING caused my starter box to turn backward....or did it? It never had before. It's not like reversing the wires would reverse the starter box engine shafts? Or CAN IT?
3. Is it possible to have some form of "backlash if hit a spnning flywheel on a rubber wheel that is stationary? I don't think so, it's not like the rubber wheel has a OWB.
The good news is I stopped it immediately (never going past 1/24 throttle. I did let it cool for five min...and he it is 5:07 seconds after up above:
