Bolt sd5 w/ gate aster issues

[LazzurusMan]

Fitted a gate aster and some prometheus 16.1 gears to a friend's bolt sd5 yesterday.

 

The aster thinks that full auto is safe, goes into full auto fine just before it clicks into full auto.

 

Second issue, we've destroyed the prometheus reinforced gears. As in multiple teeth have come off.

The only thing I can think of is bad swimming, or a bad gear set. 

 

 

What are peoples thoughts?

As regards the gears, that's an interesting question.  Have seen one video on Youtube where that particular brand failed very quickly. Tried to fit a set recently in a LCT gearbox (also 16:1 ratio) and got nowhere. Far too much resistance between the gears and didn't feel comfortable putting no shims on one gear underside. Eventually went with a different brand.

 

Which gear (bevel/sector/step) did the teeth fall off, out of curiosity?

For detailed answers, we'd need to know your: battery, motor, spring, and any other mods or items done to this thing.

 

Prometheus gears are extremely outdated and overpriced--they're not an upgrade over stock sintered gears, which are really fine the vast majority of the time (assuming QC was done and there aren't any cracks in the gears).

 

99% of the time, your best aftermarket gear choices will be Rocket/SHS. They work, and the amount of "bad sets" is a lot lower than other brands. (It's airsoft, so nothing's perfect...)

 

You could also get a set of stock-style sintered gears that are 16:1, or even simply increase the motor speed and keep the stock ratio, both of which should achieve the desired effect.

 

When you install a new gear set, make sure the motor is installed correctly, with two wires at the back of the motor grip, and the polarity is correct, so the motor isn't spinning backwards. Check shimming with the two halves of the gearbox screwed tightly shut, and check piston clearance as well, making sure the piston can drop freely in the shell when the two halves are screwed together.

 

Also, if you happen to be using an aftermarket motor, PME can easily cause teeth to be lost. This depends on the rest of your setup, which you haven't shared.

 

And a final note on the drive train, if this is the Bolt I'm thinking of: EBB systems are inherently fragile due to the vastly increased stress put on the motor, gears, battery, etc. If you really want your system to last, you should disable the EBB. Your motor has to pull that extra weight, and your gears have to feel that extra weight.

 

On the Aster issue... Check your sticker positioning. And check it again. I can't remember if GATE allows you to recalibrate selector positions, but if so, do that as well.

Lost multiple teeth on the bevel gear where the motor hits it, as the the teeth fully sheered off, and a tooth on the spur gear.

We're putting it back together with the stock gears and hoping it survives testing.

Everything stock except the new gears and aster. Knowing my luck it'll be bad shimming on my part. We'll test it with stock gears and see what happens.
