LordElpus Posted March 21, 2011 Report Share Posted March 21, 2011 Check out the Falcon double hop at EhobbyAsia. It's a normal rubber, but the "bump" is replaced with the a H nub (well, bottom half of one anyway. Quote Link to post Share on other sites
Reppyboyo Posted March 21, 2011 Report Share Posted March 21, 2011 I considered giving one a go but I haven't seen any reviews of one yet. Quote Link to post Share on other sites
LordElpus Posted March 21, 2011 Report Share Posted March 21, 2011 i've installed one in my hicapa and will be doing the same in my m4 when i get the chance. Quote Link to post Share on other sites
Reppyboyo Posted March 21, 2011 Report Share Posted March 21, 2011 Cool, let me know how they perform for you. Quote Link to post Share on other sites
Reppyboyo Posted March 27, 2011 Report Share Posted March 27, 2011 Another day another issue. Changed the hop bucking to a madbull black, consistency was rubbish. The silicon version fell apart. :-/ First and last time I buy Madbull buckings. Â Re-installed stock bucking with 'fishbone' nub, left the hop on a bit high when chronoing and got a jam. Removed barrel etc to un-jam, did so and ever since my SVD has been firing full auto only. Â I presume the cut-off lever has somehow become damaged? Bit late to be taking the gearbox apart now though. Quote Link to post Share on other sites
Reppyboyo Posted March 28, 2011 Report Share Posted March 28, 2011 Right Im beginning to hate this thing. Opened the gearbox and found one of the bearing was pushing itself out, blocking the cutoff lever. Pushed it back in, thought all was well as it worked fine for the time. Chronoed fine too, consistent 345 +/-3 Â Mid way through chrono it stopped again, pressed unjamming thingy to get it to full auto. Fires again and stay full auto. :-/ Found that if I press the gear under the selector levers pivot it would be able to fire semi again. Â Also, decided to change the nub from stock to an SCS nub and afterwards somehow lost 100fps! Quote Link to post Share on other sites

Reppyboyo Posted March 28, 2011 Report Share Posted March 28, 2011 Tomorrow perhaps, put it away for the night as Im too annoyed to work on it. Quote Link to post Share on other sites
Reppyboyo Posted March 31, 2011 Report Share Posted March 31, 2011 Full auto problem sorted, needed a shim or two to stop the gear/bearing moving out. Consistency is also back to +/-3fps, no jams. Â However on close inspection of the hop unit it is self destructing. Noticed 2 cracks appearing from them front of the unit and the hop arm stripped its threads. Lets see if RS support will provide a replacement. :-/ Quote Link to post Share on other sites
NookieOne Posted March 31, 2011 Report Share Posted March 31, 2011 WOW! What the .. is going on with your rifle?  I´d realy like to see some pics of your hopup unit! Quote Link to post Share on other sites
Reppyboyo Posted March 31, 2011 Report Share Posted March 31, 2011 This as far down as my hop will go, aka fark all: Â Main crack at the front, there is also a smaller one to the right: Â Finally, the hop arm. Most of the threads stripped: Â Well, either RS quality has hit a nose dive or Im just very unlucky. Which is a shame as my 97B was awesome. Quote Link to post Share on other sites
NookieOne Posted March 31, 2011 Report Share Posted March 31, 2011 The SVD is awesome too, really dont know what happend there. Â Â Thanks for the pics! My SVD still looks and shoots perfect .. after almost 4k rounds on 2,4j. Â Â Maybe there was some dirt on the hu threads wich grinded them down? And the Cracks .. normal use couldnt cause such demage... strange and uncommon for a RS gun... Quote Link to post Share on other sites
yuanshi23 Posted March 31, 2011 Report Share Posted March 31, 2011 From handling a mate's RS SVD, we've noticed that with such a freaking long barrel, the only thing to get this beauty accuracy is for it to shoot above 1.5 joules. We tried putting in an M100, with everything stock, and accuracy was pants. Put the stock spring back, shoots *****ing hot, but straight, extremely extremely straight. And far. And this is with a polished stock barrel. Quote Link to post Share on other sites
NookieOne Posted March 31, 2011 Report Share Posted March 31, 2011 The stock spring is a RS M130. I use a Guarder M140 .. seems to bee too long .. but fits and shoots very well Quote Link to post Share on other sites

And this is with a polished stock barrel. Â With a Guarder SP90 (350fps, hop off) and everything stock the accuracy is pretty average. Consistency is very very good but with .25`s it takes too much hop to get them to fly far, losing too much fps. Â I better hop rubber should sort this however. (When the guarder clear worked, the range and accuracy was fantastic). Quote Link to post Share on other sites
NookieOne Posted April 1, 2011 Report Share Posted April 1, 2011 My MosFet with cooling: Â Â ... and my unjam-button: Quote Link to post Share on other sites
Reppyboyo Posted April 1, 2011 Report Share Posted April 1, 2011 Well RS support seem uninterested in helping with the hop issue. Ordered a replacement hop unit from ehobby asia. Once that arrives and is fitted the SVD will likely end up for sale. Ive had it in pieces more than I have skirmished it. Quote Link to post Share on other sites
Reppyboyo Posted April 16, 2011 Report Share Posted April 16, 2011 Well got a new hop, trying to install today but have come across a problem. I cannot get the (new) hop unit on to the barrel. It keeps dragging or bunching up the hop rubber along the way. Tried lubing it with silicone spray but that doesn't help much. Tolerances are a bit silly. Â Anyone know how to get around this issue? Seriously considering glueing the rubber to the barrel at this rate. Quote Link to post Share on other sites
NookieOne Posted April 16, 2011 Report Share Posted April 16, 2011 Use a TM hop rubber .. Quote Link to post Share on other sites

Seriously considering glueing the rubber to the barrel at this rate. I managed to re-assemble realsword original hop-up and rubber with lots of water and twisting of barrel. Â One time, putting the rubber into the hop-up unit and then putting the barrel into the rubber also worked. Edited April 16, 2011 by adadqgg Quote Link to post Share on other sites
wolfgeorge Posted May 27, 2011 Report Share Posted May 27, 2011 I have one question, what's the solution to locking gearbox, I've skirmished twice and one both games it locked! Â Wolf Quote Link to post Share on other sites
NookieOne Posted May 27, 2011 Report Share Posted May 27, 2011 Easy .. Â Install a Faster Motor, a 11v Lipo and a Mosfet with some kind of unjam button as shown on first post on this page. Motor is not a must since the original one ist pretty good .. but if u want more .. Quote Link to post Share on other sites
wolfgeorge Posted May 28, 2011 Report Share Posted May 28, 2011 I was thinking just a MOSFET I don't want to use a lipo on a semi only gun it's not necessary IMO, it improves only trigger response but it wears down internal parts faster. Â Wolf Quote Link to post Share on other sites
The Jam Posted May 28, 2011 Report Share Posted May 28, 2011 I was thinking just a MOSFET I don't want to use a lipo on a semi only gun it's not necessary IMO, it improves only trigger response but it wears down internal parts faster.  Wolf  It wont wear it down any faster than a 9.6v on semi.
