What sort of current protection? I was thinking if a self resetting breaker of some kind to guard against that sort of thing.

Toruk, any ideas on how we can solve the 180 supply chain issues? I am still more interested in those than these.

A PTC thermistor is probably what I'll be using after hearing about the Tacmod failure. The thermistors used on helicopter motors for blade obstruction protection should do the job for 180s on 2S. A resettable circuit breaker (either self-reset or push-button reset) should work too as long as it doesn't trip on start-up. I'd guess it'd be either a 15A or 20A breaker for 2S. 20A would be less likely to trip on start up but might not trip at all if the pack voltage drops too low.

Definately need something on the pusher. The blade fuse on the Stampede is fine, but there isn't enough space in the RS for a big fuse and holder!
I haven't had a single motor failure so far.

Agreed. At least with the flywheels you can just let go of the acceleration trigger if something goes wrong. That's one downside RS pusher cycle, it won't stop supplying the motor with power until the pusher returns to it's start point. PTC fuses tend to be nice and flat so it's fairly easy to find space for them plus, because they reset themselves as they cool down, you don't have to make them easy to get to.

A PTC thermistor is high on the list.

I was researching ATC fuses since I could make them plug in externally. However, I suspect there would be problems getting them to blow reliably and quickly on a prolonged stall 100% of the time and yet not have a risk of blowing spuriously. A different type fuse might be required.

I am using a xtreme pro180 pusher in my next build (3.1 XDC). One, I don't have any of the stock PTCs from blade motors, and two I don't know how they would do with the xtreme. The pusher PTC would be a motor specific part. Might have to order a few and test them for each motor option. The same spurious trip consideration applies. I can really hammer on a RS semi-auto (watch airsoft vids) on occasion, and besides, you shouln't be able to make a gun fail/die/cut out just from shooting technique. Ambient temp also factors with PTCs. So it will be a R&D project.

I am mostly going to focus on avoiding crashes before they happen, for now. I also suspect that particular unit has magwell rail wear as a factor and that could be addressed (which may also turn out to be an accuracy upgrade).

I heard something along the lines of Zinky was trying to reorder, and this site was mentioned to him. However I have heard of no one yet contacting this distributor above and getting any sort of answer about the 3240.

I am not too sure on how the supply chain for Mabuchi works. It seems strangely secretive and closed. I am not sure why distributors are so few.

I am experimenting with omitting the power lead from the cycle control switch, leaving only ground.

My Vulture has a misbehaving defective switch that does not "snap" cleanly. It acts in this manner. On occasion you can get the pusher to land extended, but it is very unlkely and rather harmless when it does happen. Controllability is better. Those annoying trailing bonus shots never happen and even a 3S (800-900RPM) doesn't make it run away. As a bonus, it does give full authority over power to the trigger and if you aren't pulling, it can't do anything except coast and brake.

I have contacted that seller for a quote, about 5 days ago, not received a reply yet.
Interesting point about the pusher switch, worth a write up? Maybe see how that set up would work with the switch plate I sent you? Always looking for ways to improve how I wire those.

I will give that a try, it's just a quick desolder and heatshrink to go from live center to dead center. Or you could stick a switch or a connector in there. I will do more testing with the 3.1 build.

I wish I would have been able to review the kit sooner, I was supposed to get a RS in on trade but I got cash instead. Everything I do have is either already wired, not mine, extremely important, can't be front-wired, doesn't accept a standard FCG or some combination.
