Ive done some measurents and calculations and I think I'm fine my current cylinder to barrel volume ration is 1.92:1

Yes all scratched like something had scraped across the bottom

I did and some air seal issues so replaced the plastic set with aluminium including an xt cylinder the gun now fires flawlessly my feeding issues are gone it's perfect with fps variances no more than around 5fps. I did notice that my stock broken cylinder only had the port on one side but the xt had 4 after some googling I found my stock was a 3/4 cylinder so wanted to make sure this is not an issue

GI'm a bit confused around cylinder sizes, my rifle has a 290mm inner barrel so using the guide on the store page I purchased a 60% cylinder and installed it (old one died) now I've found out the stock one was a 75%. Bearing in mind my stock barrel length was only 270mm was my rifle over volume and will my current cylinder size cause me issues

Perfect cheers guys that's exactly what I wanted to hear

So my gun is back up and running perfectly with no feeding issues or anything so in the interest in preserving the gearbox as much as possible I wanted to know if precocking is bad for the gearbox?

Cheers buddy, I think my plan is to gwt this up and running and then grab a new gun ASAP and as you said keep this spare. Wish I had found this forum before I got my gun as you guys have been brilliant and it would have saved me a lot of hassle, money and stress

It was all stock bar the gears and mofset till this happened as the stock compression set was fine and had no issues but it all got totalled when the gearbox cracked. I tried to get a slot with luke from negative airsoft to fix it but he has a backlog of 3 months so I'm trying myself and hoping it works out

3 games 0900 to 1600 so I'm hoping that was just a lemon and the one I'm receiving will hold out longer. I have purchased the lonex pom mushroom head silent piston and rocket silent cylinder head which I am hoping help reduce some of the shock. I'm going to grab a retro arms hop u it as it is more stable than the plastic ZCI one I am using and has a rubber washer nozzle end which in theory should also help reduce shock plus my ZCI hop unit has terrible fitting with my maple leaf barrel it wobbles all over the place. Also hoping the different design of the retro arms feed tube might help with my feeding issues and be ready for the retro arms split gearbox when I get the money together to grab one

Ive decided to go for the lonex pom mushroom head piston head and rocket silent cylinder head as supposedly these absorb a lot more than standard and reduce the risk of cracking. Now I am just debating whether to stick with my 13:1 gears or swap to something less stressful

I am hearing conflicting things about the rubber dampener at the front of the fps cylinder head preventing cracking and actually speeding it up?

Cheers buddy! Has anyone tried FPS Softair cylinder heads and pistons they are advertised for HROF

I forgot to mention I am using 11.1v 30c batteries as well

Do you think the orion will hold up for a while? I've got some replacement bits in my basket: Gearparts pom piston head XT steel heat resistant cylinder 60% XT cylinder head with 2.5mm pad ZCI 14 tooth cnc piston XT 21.4mm nozzle E&C tappet plate The gears and bits I currently have are: ZCI advanced 13:1 gears short stroked by 2 teeth M100 piano wire spring ZCI high toque motor Perun V2 hybrid

But where is the fun in that 😏 In all seriousness I purchased all the bits for a 13:1 build short stroked the gears purxgased q perun v2 and everything and the trigger response is amazing. I do however have a set of 16:1 zci advanced gears but didn't use them because someone told me they are pretty much identical to the stock 18:1 gears

So if anyone has seen my other threads my gearbox cracked and the piston shot out the front. Out of shear luck someone on this great forum had a spare orion gearbox that they sorted me out for postage and a coffee!! So, I don't want to be in the same situation anytime soon and wanted some advice from you guys on what if anything I can buy or do to help prevent or mitigate gearbox cracking? I have seen these cylinder heads do these help? Thank you all in advance

Mate you are a life saver ping me a message with the details

So I'm now desperately trying to find a replacement gearbox shell for my specna arms edge 07. E&C are out of stock everywhere the lonex apparently does not fit so I'm now looking at the modify gearbox shell and wanted to know if they fit?

Anyone know any other gearboxes that will work with the spacna arms edge series?

No worries thanks for letting me know, I will keep looking

Cheers buddy, that seems easy enough. Just need to find one now

@ak2m4do you have any idea when you might be selling the gearbox I have a new piston, piston head and cylinder saved in my basket in your store as they all got destroyed when my gearbox detonated so I can do it all at once

E&C is exactly what I'm after as they fit perfectly but have been unable to find one anywhere
