upgrading externals on my cyma

[SCAR_Jester]

im also gonna record it all if you guys interested im not gonna cut out any failures if there is any if you guys know any good drop in hop up units please let me know thanks

Technically speaking there is no such thing as a drop in hop up..
You get a hop unit (the housing of the full assembly), the bucking/rubber (which usually comes with a nub, but most buy their own one).#

There are plenty of hop-units out there, too many in fact, go for something in your price range and metal and it'll be fine.

Cheapest hop rubber that will do you well I'd say the G&G green and nub included (flat hop mod and you'll be soaring) -  very easy to do.

And barrel.. now...  there's talk on what's best for this but I have always had good results (in budget builds) with a ZCI tightbore.

You can get much better ones like Edgi, PDI, Prometheus and madbull steel, however I have always had good results with ZCI.

Good luck, I hope the build goes well. - Last note, TAKE YOUR TIME

The first thing I'd suggest that  you do is to strip your gun right down to its components parts so that you're clear on what's in there and how it all goes together.  It's a very satisfying process in and of itself.

Once you're confident in taking it apart and putting it back together - and get some pictures and measurements of the components while you're in there - then you can start swapping things around with a bit more confidence.

i already stripped my cyma to bits few times and put it back together also watched few videos on youtube about hop ups and how to make a flat hop which i will try to do next month

im not sure i should try on stock hop up first i will decide later

Don't bother with a Lonex motor. There's better for less.

It's alright tbh, gearbox shell is a little brittle, but if you don't run it crazy speeds or crazy fps you'll be fine.
The best shell would be the Lonex gearbox, the parts inside though are mostly okay, some are sub par.

Looks good to me, however I wouldn't use an aluminium piston head for normal guns (only for DMR's)
I would run this setup on a 7.4v lipo and no higher as you wont want to do advance tech stuff to stop pre engadgement.

Remeber you need a nozzle, cylidner head and cylinder (cylinder brand doesnt matter)
And a spring and a spring guide
Annnnd a trigger switch assembly
