R-hop experiences

[captainkirk05]

I just finished my 2nd install with no luck, the thing shoots same as a standard bucking and nub. I don't know if I've goofed up the m-nub or rhop patch. Could you detail just what you do with the m-nubs starfolder?

R-Hop:

Does the FireFly Buffer Rubber work at all with the R-Hop?

[Star_folder]

I cut the patch lengthwise to match the window, then I cut off the legs until the patch is level with the outer diameter of the barrel. I then sand the inside face of the patch until it's flush with the Inner diameter. I put the bucking on and am done.

The bucking should have the nub removed.

and yes, the Firefly Buffer Rubber will work with the R-hop, it's just like the M-nub without the stickiness or modifying your hop up arm.

When sanding the contact patch, is it correct to say that you want the bb contacted by the entire surface of the patch?
Like this:

In other words, you would't sand it just so the top of the bb makes contact, otherwise that would be essentially the same as a mound.

[Star_folder]

No, not like that. While it can be done, it would take hours of fine tuning and it wouldn't be an adjustable hop. When pressure is applied to the patch, the whole patch doesn't move, the center just comes down. Think about any rubber arch that you could make, when you apply pressure to the center of the arch, the center comes down and the sides spread out. The same is true with an r-hop patch.

This means that yes, you do sand it in a way that only the top of the bb makes contact with the patch. This is very unlike a normal mound, because a normal mound only makes contact with the bb at a point. With an r-hop, the bb gradually gets hop from the length of contact from the patch. With a normal mound, all the hop is applied all at once. This is one of the reasons that the flat hop and r-hop are better because they apply hop more consistently.

Awesome man!
I appreciate the quick responses to my questions.

I have been reading all week all the info I can on both the R-hop and Flat-hop mods and I feel like I am drowning in text. Each forum I have been reading seems to include info others do not. Trying to get a firm sense of both mods so that I don't make the mistakes that have already been made and addressed.

I will probably have a couple more questions for each mod over the next few days.
Sorry if I am asking something that may have been covered in its respective thread on a national forum.
In some cases there are contradictory accounts of user install processes.

Thank you for your help.

There is LOTS of information out there on these hop up mods, and it does get very confusing. I'm more than happy to help you sort through the info.

Thanks for the reply Starfolder, but I was meaning the M-NUB, not the actual rhop patch. Do you leave it as is, or cut it down a certain way?

[Star_folder]

For the r-hop or flat hop? For r-hop I leave it as is, for flat hop I have to add a little material to it.

[captainkirk05]

R-hop. I trimmed down my m-nubs on my attempts. First I trimmed it length wise to fit the window, then took about 1/3 to 1/2 of its vertical thickness off, then sanded down the sides so it wasn't squished by the walls of the window it moves through, making it bulge where it was flat on the bottom. I have a feeling that I shouldn't have all of a sudden.

[Star_folder]

Well, I do cut them down to size to fit into the hop up chamber, but I don't usually sand the sides. To be honest, I don't usually use the M-nub, I just use a piece of sorbo to use as the nub.

I just use a piece of sorbo to use as the nub.

What is Sorbo?

[Star_folder]

Sorbo is short for Sorbothane. It is a shock absorbing, closed cell foam that is often used to correct AoE in Airsoft.

I cut up some blue silicon tubing I got from a local hobby shop today. Sanded it down to ir-hop size, installed it, and whamo! It works exactly the same as the normal ir-hop. Guess I'll be saving some money from now on.
