Tm Sopmod blowback question

[Chevaliernoir]

I'm looking at upgrading my tm sopmod and one of the things I'm going for is a higher rate of fire. But I have heard of people destroying their blowback functions by making rof too high. Is this true and if so Is there a way to stop it happening?

Question is - why do you want rapid ROF?

That would be his choice. Some people want it, others don't. He posted this thread to get advice not for his request to get questioned.
If you don't have anything helpful to add to the discussion don't post.

Re: Tm Sopmod blowback question

depends on how fast you want to go,which batteries are you using at the moment, are you using lipos? if not then making the change will increase the rof depending on the amperage of the lipos

Re: Tm Sopmod blowback question

I'm pretty sure if you up the ROF to ludicrous speed then you need to get the heavy blow back weight or up rated weight return spring. Other wise the blowback unit tries to return after the piston has cycled again and they meet in the middle with bad juju happening.

I've heard of guys running with 11.1 20C batteries.
My sopmod on 9.6v NiMh is pretty quick, quite a few people always ask what I'm running.

Tbh I personally wouldn't recommend pushing the RPS much past 18-19, maybe 20 at a push. It just puts a big strain on the box.

SOPMOD's are ok on 7.4's but some people have had issues running them on 11.1's. If you start running them too fast you can end up with other issues.

My advice would be to change the batteries up to 7.4 lipos unless you already have, I wouldn't go higher on battery voltage but thats me.

You'll kill your Sopmod. You'd have to spend more than the guns worth getting it upgraded so that you wouldn't shake the thing apart on a 11.1.

Change the gear set, piston and head, selector plate, nozzle and DONT put the heavy weight in. Unless you have the reinforced body and get the buffer tube shim kit for the future.

Also there is due a Black Talon Mosfet but no ETA

Don't bother with an 11.1.! The gearbox will be attempting to turn over quicker than the recoil weight can perform a cycle. Run it on a 7.4. Rof is fine, easily enough for what we all require. Improves trigger response too

Re: Tm Sopmod blowback question

I run a 7.4 lipo at current. Was considering putting a higher speed motor in. Maybe a g&p m120 as I have a few spare. Might have an ics motor also which is not quite as quick as the g&p. wouldn't dream of going as extreme as an 11.1

Re: Tm Sopmod blowback question

do you want a higher rate of fire or a better trigger response

[Chevaliernoir]

Re: Tm Sopmod blowback question

Bit of both would work for me if possible. But trigger response at current isn't too bad so a slightly higher rate of fire would be priority

Re: Tm Sopmod blowback question

If your running 7.4 then you want a hi-torque motor not high speed, this will give you quicker response and slightly higher speed as it can cycle the box with less effort.
9.6v will give you more speed without the need to totally upgrade the box. This I do know.

Re: Tm Sopmod blowback question

Question though.

Why do you want a higher rate of fire?
Other than its your choice, which is a given.

Tbh a recoil sopmod is just the wrong gun to do it with, it also achieves utterly nothing.
