Airsoft Store Canada Presents - How To Install an R-Hop
 
Okay so finally, here it is. Probably not the best video I've made but it should answer a LOT of questions for a LOT of people.

Comes with 50% more accuracy and consistency tips.

THIS. couldn't have explained it any better. +9001 =D

first installs (and the old method) tend to look like Russian Torpedo Rocket ! - YouTube

so first timers: don't sweat it.

Oh no, the secret is officially out! :eek: Anyways, good guide on explaining the basics of a R-hop installation.

Awesome man!

Question now though, what is the other part of the hop kit tool for? The triangle thinger?

zone 69 April 19th, 2013 21:56
Nice I can even do it now. :) I been using the O rings on the barrel for year's now.

The triangle thinger, let me guess it's to gage the R-patch is flush with the out side of the barrel.

Chiba April 19th, 2013 23:53
Been doing that. I can still never get the outside of the r-hop to sand down flush with the barrel entirely no matter how much I sand (of course not below the outside of inner barrel). This causes the r-hop to push down sometimes.

Also I find my R-hop isn't consistently applying spin.. sometimes I have to shoot a few BBs (it would shoot like under hopped) before it is giving me a nominal trajectory.

Anyone have an idea why? Let me know if you need specs.

you can use a razor blade (super thin single-edges or a halved double-edge shaving blade is perfect) to cut the outside of the patch. doesn't come out as clean, but is easier...also easier to screw up too. ymmv. the sanding method definitely takes a little patience.

when you're adjusting your hop up (same goes for 99% of all hop up units on the market, r-hop'd or not) make sure to adjust up (increase hop) slightly after decreasing the hop setting to have the unit apply pressure properly.

The shelf? It's basically in case you need to rework the R-hop patch channel in any way. It also makes it easier to hold if you're doing some sanding. I glued some sandpaper to the inside surface to hold patches better but for the most part I haven't really needed to use it.

Like I said in the video, your first install isn't going to be amazing, but if you're lifting .25g+ then a LITTLE bit of protrusion/intrusion isn't going to break the deal.
What hop nub are you using?

Also, are you testing out with a completely full mag? I ask because sometimes your tappet plate spring isn't strong enough and upward pressure of BBs pushes the nozzle out of alignment. If so, test again with a half-loaded mag.

Its not amazing I agree. My inner radius of the r-hop is fine, its the the outsideof the patch. Its always close, but not flush, causing some over hop sometimes. I was hopping 0.3g using a MAG midcap for M4.

I was using a stock G&P tappet plate spring, so hopefully its not that. If so, I guess I should just cut the spring a coil to make it stronger. Is there a place in Toronto to get springs?

I was using a regular round nub as I was still trying out the R-hop.

use some silicone oil on the sand paper and give it the ole shoe polish style sanding while it's glued on the barrel... if you have a 6mm cylinder insert it into the barrel to keep the shape of the patch so it doesn't collapse while you apply sanding pressure, just be careful you don't scratch the inside of the barrel.

Stealth April 23rd, 2013 11:14
I'm going to jump in and say that the quality, distance and consistency of your groupings with the R-hop system is DIRECTLY attributed to how uniform and consistent the inner r-hop channel is. That's why I highly recommend not touching it at all and to run a Prometheus Flat-hop tensioner for maximum contact area of that patch.

JDoorn April 24th, 2013 12:03
Does the r-hop work with 2 piece hop up units? I dont see why it wouldn't, just wondering if there's something I should watch for with a 2 piece...

Stealth May 2nd, 2013 16:44
Doesn't matter whether it's 1-peice or 2piece. Although 2-piece systems I have found to be more "lossy"

So I finally got it installed. I only bought 2000 grit at first and that was imposssible. I kept applying oil and made my patch swell a lot. Had to recut it to fit, bought some 400 grit sandpaper and now it's finally installed. There is no barrel intrusion on inside or outside of barrel and the hop up is engaging normally.

Going to have to go to my old mans place to do tests, but it looks pretty good. Wish they gave a little bigger patch for how much they cost and for people who screw up like me. :D

! On mobile; sorry for any spelling mistakes or autocorrects!

lurkingknight May 2nd, 2013 17:12
it shouldn't be swelling if you're using the right silicone oil.
