I'm getting my UTG Mp5 this coming monday, and i'm very excited.

 

I'm wondering about a few issues:

 

A friend of mine just got a utg warhawk, and he shot about 200 rounds semi-auto, and started firing fully auto...after about 60 rounds of fully auto, the guns gears started grinding...and he didn't want to take it apart and void his warranty from shortys.

 

Is there any true way to break in a UTG's gears without having to take the gearbox apart? This is my first aeg and im completely new to the deal.. I have some friends that can help me with the wiring, which makes me excited, but i don't want my gears to mess up before i really get a chance to use the gun.

 

Also, using silicon lube, where do you spray it, and why.

 

 

Thanks for the help in advance.

ok thanks... now um... would a 9.6v nunchuck 2000 mah battery fit in the flashlight grip if it was in a "V" formation?

 

Yes it will I just tried my CA B&T stock taclight forgrip on my old UTG and my 2000mah nunchuck did fit. A very very tight fit but it did work. the main problem is there is just way to much wireing in the foregrip area but I over came that :) .

alrighty then...umm sorry im only posting ym questions as they come up lol. anyways...i just ordered a 8.4v 3300mah battery and i was wondering, 2 things, 1=am i going to need a small to large adapter thing? and two, is it going to fit in the foregrip?

 

Yes you will need to buy a small to large adapter and there is absolutely no way it will fit in the handgaurd. Just rewire the extension to the fixed butt stock and use the A4 stock. I also strongly suggest that you get a new extension, for the stock extension has lots of restriction.

Everything looks good, but i'd skip the piston, cylinder head, and pistion head upgrades. Everything else you should be able to do for under $60 usd. I'd suggest doing the wire upgrade before any of the other things though, as you're not going to be able to pull that m100 without it. I noticed you also thought about doing some high speed gears. Again, after doing the gears and all the upgrades, you should have just purchased an ICS or CA for the ammount you'll spend. With the high speed gears, and all the stuff above, and the price of the gun, you're basicaly spending what you'd have spent on a higher quality gun. If you want a faster rate of fire, get the 9.6v nunchuck batt and put it in the stock instead of the high speed gears.

IMO the highspeed gears are still a waste.

Anyone who reads this should know that UTG was V1 so alot of upgrades have been made. One of the upgrades is new wiring and it has no need to replace now (on V4). Also the motor has been upgraded and it now has a good pouch to it and it will more then likely will not need to be replaced(unless you upgrade alot of stuff other then Piston, Piston Head, Spring, and other small things). I have the Well R5 MP5 V4 witch is the same as the UTG MP5 V4 with only slight differences sense UTG just took the Well gun and repackaged it. I have upgraded the Piston, Piston Head, and Spring and its been running great!

 

But the point of this post was just to mention that the UTG MP5 in this topic is a V1 so alot of problems have been fixed.

Okay, its taken me forever but I got the gun put together and I test fired it today, well, it didnt quite work, first, I heard a horrible grinding noise which I fixed by ajusting the motor, then I tried it again, I didnt have a grinding noise but my gun couldnt pull back the spring (a PDI 120 + 10) I have upgraded the wiring as per statics instructions and what I believe whats wrong with it is...

 

1, spring is too big,

2, I messed up the wiring somwhere.

3, My spring guide as crooked when I put my gearbox together, it was pointing down so I am assuming that it might be interfearing with the gears or that its not letting the spring compress correctly and it wont go in the piston stopping it from being pulled back.

 

Please reply, I need to fix this by saturday.

I'm about to buy a used one, and the previous owner opened the GB and wrecked the spring guide, lost 2 bushings, and just didn't put it back together...so he lost/mixed up the screws, could you help me out with what kind they are? As I don't want to destroy the GB. Thanks.

 

EDIT:

 

And these are the proper gears for replacing the stock ones, right? (He lost those as well...)
