Solly4568 Posted July 20, 2018 Share Posted July 20, 2018 So I have a CM16 R8-L and I would like to turn it in to a DMR. I have been looking around and found that one of the easier ways to drastically increase the FPS is to insert a new spring but would this stiffer spring be too tough for the current motor and if I was to upgrade the motor as well would it shred the gearbox. Any help would be appreciated Solly Link to comment Share on other sites More sharing options...
BigStew Posted July 20, 2018 Share Posted July 20, 2018 If you up grade the spring with out up grading anything else your gun will break something its just a question of when. Before you do anything make sure to check what the sites you play at requirements for DMRs are. They will require mechanical/ electrironic single shot locks or may only alow guns that were manufactured as DMR. also before you up your fps look at changing you inner barrel and hop rubber/hop unit this will effect range far more than a fps increase.

MisterG Posted July 20, 2018 Share Posted July 20, 2018 DMR FPS varies between 400, 425 and 450 on the sites I play at. Cheers G Link to comment Share on other sites More sharing options...
Solly4568 Posted July 20, 2018 Author Share Posted July 20, 2018 I think so, what was the original strength spring as if you upgrade it too much then you might burn the motor out Link to comment Share on other sites More sharing options...
MisterG Posted July 20, 2018 Share Posted July 20, 2018 Normally if the gun was built for higher springs you would expect the internals to cope, but may depend on the manufacturer/model. AFAIK the main issue is when you take a gun made for 350FPS and then take it up much higher with a spring upgrade, motor may not cope, gears etc. if you push it past 400 you wont be able to use it at Gunman unless you downgrade again.

BigStew Posted July 20, 2018 Share Posted July 20, 2018 If you go above design spec it's going put extra strain and will shorten the life of your gearbox may last years may go the next game. my personal opinion if you are going to up grade gear box up grade everything and stick to the same brand.

Wo1f Posted July 27, 2018 Share Posted July 27, 2018 Makes sense to upgrade the internals. Adding components that will give you a better air seal will give you more FPS and a tightbore will up the FPS too. That way you’re putting less strain on your gearbox and you will not need a beefy motor/battery. Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted July 27, 2018 Supporters Share Posted July 27, 2018 Airsoft gearboxes are made of random mixes of Chinesium, and I'll note that even the cheapest CYMA guns shoot 400fps as stock. They're toys, they're going to break. Why not enjoy them as much as possible before that happens? I do buy into the idea of radiusing them though: http://www.sqairsoft.com/how-to-radius-your-gearbox-shell.html Link to comment Share on other sites More sharing options...

Supporters Rogerborg Posted July 27, 2018 Supporters Share Posted July 27, 2018 I'd love to take credit for Chineseum, but I blagged it from Canuckistani YouTuber AvE. Warning: thar be a deep, deep rabbithole if'n you go delving in it. Link to comment Share on other sites More sharing options...

Then we get into the Joule creep slap fight. At a site with a 500fps / ~2.3J limit for semi auto DMRs, I can't see why you'd use anything else.

Solly4568 Posted July 28, 2018 Author Share Posted July 28, 2018 at my site they are limited to 450 and bolt actions to 500 so i get that it is not much of a step up but still dam Link to comment Share on other sites More sharing options...
Sheepy Posted July 29, 2018 Share Posted July 29, 2018 I went down the upgrade route with a Cyma keymod m4 to DMR and can tell you first hand the upgrading just the spring will end up with chewed up gear teeth and a very sluggish motor. Unless Cyma have updated them. However g and g internals I’ve been told can be a bit meh when you’ve been fiddling with em Link to comment Share on other sites More sharing options...
