"Got this on sale for $135 about a month ago and im very impressed. On an 11.1v battery the trigger response is really good and can even keep up with upgraded aegs. The full auto rate of fire isn't the fastest but for indoor cqb the gun works perfect

"I got this gun when it was on sale for $160. Carbine m4 stock. Field chrono shot around 350-380. This thing is perfect for my first gun. People are saying it can’t be upgraded internally much. But regardless this gun shoots great, has an okay distance, and is relatively cheap compared to other starter guns. Best gun I’ve bought so far. See this lasting a while.

"So far this gun is great. I got the SBR length with the tanker/PDW style stock. The stock is pretty darn secure for being a PDW style. It obviously has a little bit of wiggle, but it's not bad. I bought a TITAN 7.4 lipo (stick type) and it barely fits. You have to modify the end cap for it to fit, but it's just 1 thing that you have to unscrew inside the end cap. It's fairly straightforward.

The only problem I am having is that after about 20 shots, the gun buzzes 5 times and then won't respond unless I unplug and re-plug the battery. If I remember the manual for the MOSFET correctly, I think this means that the gun is getting too much voltage? I do not remember, and I would love it if someone would correct me. It happens with the spare 9.6 I have lying around as well. If anyone has other info, I would really like to know, because I can't find the manual online anywhere. (it was in a separate manual from the regular one for the gun itself)

Overall, from what I can tell, the gun is fantastic, and the hopup has no trouble hopping .25s, so I would guess that it could hop .30s with the stock internals.
