OllieAirsoft Posted August 12 Share Posted August 12 hi all, got an mcx with a fusion engine inside. maxx m4p pro hop, max trigger, small Prometheus inner barrel, maple leaf super macron 70 degree bucking. and i cannot seem to hop flat any weights. 0.32g get sent straight to the moon, running at about 100 psi at 1.1 joules. any ideas what can be done to change the overhopping, i dont really want to get rid of the maxx hop up but if that needs to be replaced for one not as good i get it. could a longer inner barrel and less psi sort this issue? could it be to do with my fcu settings? is it just a simple nub swap, and can any nubs be used in a maxx hop up?

Supporters Adolf Hamster Posted August 12 Supporters Share Posted August 12 Are you using a regular nub, or the included r-block that the maxx has? Link to comment Share on other sites More sharing options...

Why are you using a 70 degree bucking at 1.1J? You don't need more than 60, which would make the bucking more flexible and giving you more range of motion, which might alleviate the overhop.

Not 100% the same, as it's an AEG, but I use a Maxx Model M4A-PRO + the solid concave nub + Maple Leaf MR 60 degree bucking + 0.32g BB's and it shoots perfectly with a huge amount of range (and power wise it's almost dead on the 1.14J limit). I've three RIF's with the M4A-PRO in, they all shoot incredibly well, however this hop unit is like an F1 car in that you need to have it setup perfectly to get the best from it (nozzle etc. need to be perfectly matched). I agree as another has said that 70 degree is too hard for the UK. A question for the OP, do your BB's still "shoot straight to the moon" even with zero hop applied?

Looking at the M4P-PRO it uses the exact same nubs as the M4A-PRO... https://www.maxxmodel.com/image/cache/catalog/MX-HOP010MP_01-1000x1000.jpg ... the rubber cylinder, soft foam square or the solid concave, so if the OP is still getting too much hop with it set to zero / 0 then there's something very amiss 🤔 Link to comment Share on other sites More sharing options...

I was running a 50 degrees, that also had the exact same over hopping issue, so nothing to do with the bucking On 12/08/2024 at 14:17, Adolf Hamster said: Are you using a regular nub, or the included r-block that the maxx has?

And this substantial over hopping was with it set to zero / 0 on the dial? Link to comment Share on other sites More sharing options...

And this substantial over hopping was with it set to zero / 0 on the dial? It has the circular one installed, and correct yes I only got the one installed with the bundle (nub). and yes hop set to zero and still so much hop is being applied I presume from reading about your set up, I need to look at getting hold of a concave nub. Do you know of anywhere within the uk that sells one ? Link to comment Share on other sites More sharing options...
