Skippy Posted February 9, 2009 Report Share Posted February 9, 2009 (edited) Rightio, the Revolution M110 GB turned up and I installed this into my VFC HK416 this morning. Initial impressions (using a 4300ma 8.4V battery NIMH), very snappy (responsive) and smooth. The trigger has a very short pull (so short I thought it was stuck at first) and the response is much better than my standard ver 2 GB fitted with extreeme fire AB Mosfet. (I havent got a PTW to compare to atm) Installation Easy to install but you need to change the cam that engages the selector plate with the Systema one included (this was a tight fit). Performance FPS is a steady 311 (95m/s) ROF: According to the chrono its doing 20 s/s (which I assume is rps, correct me if this is wrong) with a 4300ma 8.4V battery. And 26 s/s with a 2100ma 11.1 lipo No feed problems to report. I'll update this again after I have skirmished it. Edited February 9, 2009 by Skippy Quote Link to post Share on other sites
Magsz Posted February 9, 2009 Report Share Posted February 9, 2009 Did you chrono with .20's or .25's? 311 fps with an M110 spring is very low. Quote Link to post Share on other sites
Skippy Posted February 9, 2009 Author Report Share Posted February 9, 2009 (edited) I always chrono with .20's mate . I put around 200 rounds through it today whilst testing and the FPS remains at 310. Edited February 9, 2009 by Skippy Quote Link to post Share on other sites
Captain Darling Posted February 9, 2009 Report Share Posted February 9, 2009 What hop up you got on there Skip? Quote Link to post Share on other sites
Skippy Posted February 9, 2009 Author Report Share Posted February 9, 2009 Its the VFC HK416 standard one mate. I'll try this out in some of my other AEG's over the coming days and let you know how its goes: CA M15A2 Custom CAR15 Quote Link to post Share on other sites
RSM Posted February 9, 2009 Report Share Posted February 9, 2009 Was that 310fps with hop set at all? It could be that the Revolution has a full cylinder and you are using it on a M4 length barrel? An M110 would put out 363fps in a perfect world but the lowest I've seen from an M110 when everything is correct is 352fps. Quote Link to post Share on other sites
Skippy Posted February 9, 2009 Author Report Share Posted February 9, 2009 (edited) I am using the M4 Rev 110 with ported cylinder RSM, no hop. Just tried it using a different hop unit and it chrono'd at 330 fps. I'll dig out the different hop units I have and will find the best match.

uscmCorps Posted February 9, 2009 Report Share Posted February 9, 2009 Hmmm... looks like a Revolution with M130 spring for me then. I need something that shoots around 400 fps on 0.2s (or 376 fps Max on 0.25 Bio BBs). Quote Link to post Share on other sites
Skippy Posted February 10, 2009 Author Report Share Posted February 10, 2009 Rightio, tested this with the only hop units I have to hand: Element seal unit: 330fps G&P metal one peice: 355fps So as expected it was donw to the compatability with the VFC hop unit.

bigguyairsoft Posted February 10, 2009 Report Share Posted February 10, 2009 hey skippy or anyone else does the mosfet/control unit on the outershell of the gearbox in danger of grounding out with a metal body and how is the fit in the vfc and or ca if you have tried it?

AnakChan Posted February 11, 2009 Report Share Posted February 11, 2009 I'm glad to read that U've tried a lipo on it. My Vltor setup has 12V 1400mAh NiMH and I was concerned if it'll fry the circuit (since the recommended was 8.4V/9.6V. When I get around to installing it into my Vltor, I'll let U know what mine chronos (yes mine's the exact same model as yours). Quote Link to post Share on other sites
Skippy Posted February 14, 2009 Author Report Share Posted February 14, 2009 (edited) I received and installed a Systema hop in this and the velocity came up to the 110m/s mark but with some wildly low shots. Upon some good advice from Zshot I relubed the piston and cylinder head and the velocity stabilised dramatically. I used trial and error to find the best hop rubber match and now have the setup running very smoothly. I will be switching to midcaps to avoid feed issues that arise from the weaker hicap feed springs. Thanks to Wallace at Zshot for the ongoing support.

Azulsky Posted February 16, 2009 Report Share Posted February 16, 2009 To think you have to open something like this to get it working right sucks, then again i dont really suspect they would take the time to test every single gbb, but really wow... Quote Link to post Share on other sites
Skippy Posted February 16, 2009 Author Report Share Posted February 16, 2009 In fairness this could have given a steady FPS reading if it only had a 5 shot chrono test in the factory, as it would do 5 shots at say 110m/s then a low one and so on. I only opened it up as I am comfortable with GB's and Zshot had offered to look at it for me (but I wasnt going to send it to the US for a regrease!) Cheers TC Quote Link to post Share on other sites
Xoulz Posted February 16, 2009 Report Share Posted February 16, 2009 What motor are you running it on again? since the motor that comes with the package should throw your RPS up to 30+ with a LiPo. Quote Link to post Share on other sites
Skippy Posted February 19, 2009 Author Report Share Posted February 19, 2009 I am running the motor that came with it Xoulz, I am waiting for my midcaps to arrive before I test the ROF again as the hicaps stuggle to keep up. Quote Link to post Share on other sites
