flipa, can you explain more how externals of the gearbox have anything to do with lipo usage? Because I'm not really sure what you mean. KWA's come with 16g teflon wire, good thing they didn't screw up there. That's good enough for an 11.1v depending on how much resistance there is in other places.
Lipos bump more power and dramatically increases ROF. The faster the ROF, the more cycles your gears go through in a short period of time thus wearing down the teeth on the piston and the gears. I broke a piston head too. I guess it can't handle the stress of 35 RPS. It was a everything stock G&G combat machine with just a mosfet and a 11.1v 1800MaH 25C Lipo. Also the piston teeth were all worn to the point that it's almost nothing there.
Those bearings you linked are bearings. Any bearings, especially low quality ones, are prone to failure in DMR setups. Link me a set of 9mm SOLID bushings.
Speaking from my own experiences I have never had the stock bearings fail in the SR7 or Rhino's Battle Rifle with has an M170 in it. There are NO sets of solid 9mm bushings readily available, I was just posting a possible (although low quality) replacement 9mm.
Did you adjust the AoE and add sorbo to the front? That would make the front last much longer. I have a JG piston head in my DSG gun, and it has not had any problems whatsoever and is in pristine condition after 10k rounds of firing. Granted those numbers are not as high as yours logic implies that a heavier mass impacting the front of the gearbox will cause damage faster than a plastic one.
The gun is stock except for the M130, cheapo turbo motor and the mosfet. I literally put the M130 and turbo in there to see how long it would last stock. Granted, your DSG setup is AOE and I assume sorbo'ed so that would help slow wear. I was saying that would rather have the robustness of an aluminum piston head rather than that of a polycarb one. I have had a few polycarb heads break or crack in my experience. Not to say every single one WILL break but I would rather not worry about and just go aluminum. I would use aluminum especially with the KWA 2Gx because of how beefed up the front is.
I actually have tried installing a Systema bucking into a 2GX hop up a while ago. The sleeve was too long and had to be cut to fit properly, and after that the gun would jam occasionally. I thought it was just the bucking and nub combination (SCS) but after trying a different one with a regular nub the results were the same.
Not sure what to tell you there. Mine fit with no trimming and feeds with the stock nub. I know Rhino has either a Madbull Blue or Red him his that feeds fine. He had to trim it on the end but you have to do that with every madbull.
Gears that do not use shims or are installed with methods other than using shims (such as VFC) can be considered self shimming in my view. If the gears mesh perfectly that's the bearings doing. I've had times where I needed to add .01 shims to make it run efficiently.
If you had to add so few shims to make the gears mesh then the shimming is on par with other companies. Usually they don't get it right and that's fine with me.
Where do you see me bragging about my gun builds? superchrisguy doubted my experiences with KWA so I provided some proof, showing that I have done some things with them, in no way was I bragging.
"I've dry fired my DSG P90 for 12 seconds when I had it just to see what would happen, and it just purred like a kitten. No hiccups or anything." Posts like this. It just give people the feeling that you think you know more than they do. It may not seem like coming off as braggadocios to you but it just gives me a feeling like. "This guys thinks here is better than everyone else." I'm sure you didn't meant to come off that way but I'm just giving you fair warning.
Now I am not saying that KWA is the end all be all of AEGs but I think they are better than what credit you give them. The do have their flaws. For instance I wish they had used different screws on the gearbox and the stock buckings blow but still a pretty solid AEG.
