My grease was also blue and the airseal was shitty. The internals were the same so now I know what I want to swap. Thanks again very much. I kept it simple and swapped just the motor. I couldnt get the m120 spring to fit but I figure its for the best. Next is the piston/ piston head and cylinder head.
Yeesh yeah I have the same gun and its shooting at 350 with .20s largeley in part I think due to the airseal on the thing. The p-90 is easier to work on but Gawdamn I dont want to have to crack open the gearbox again. Mostly reasembly I hate took me about 4 hours on reassembly last time before I got it. This is all gearboxes to be fair.
You gave me some great insight and I apricate it. I just bought my P90 a few days ago and judging by how you reacted to the parts in this video and I'm a little disappointed how cheap and crappy a lot of these parts are.. but hey you get what you pay for
The fix for the cylinder head can also be done with regular sewing string, you just have to be careful to wrap it around in such a manner that it mentains a uniform surface so that it won't deform the o-ring that makes contact with the surface of the cylinder. I persoanlly find it way easier to control the thickness with sewing string than with teflon tape. Now, I won't do this fix normally with people who wanna get the top of the line shit, but I've had teens with little money come to me to fix their replicas and for them I do all I can to cut down costs and stick within budget but still offer the performance they want. To this day the sweing string fix hasn't failed once, take this elitists, if it works it works.
Lol at the elitists remark at the end 😂. For sure! Sewing string is not going to dissolve in silicone oil like Teflon either! Dental floss is a great option too as it’s even, easy to work with and doesn’t dissolve easily like Teflon. I gotta try the sewing string one of these days!
@@anttechairsoft Never actually thought about dental floss, I will try it lol, now I feel kinda dumb for.using sweing string. Now I'm not sure if you were ironic about sewing string dissolving but I can guarantee that organic sewing string made of cotton for example, will not dissolve in oil, I dont know about synthetic string cuz I never used it since synthetic ish things tend to dissolve in oil, so yeah. Thanks for the dental floss tip, will def use it these days as some replicas that came in are from these young guys who just start out and dont have too much of a budget.
Great video+explanation+presentation! Thank you for sharing! Well done mate - NEW SUB 🙏🏻
Great, up to date video. Makes me more confident to work on my p90 internals. Thank you!

Amazing it can shoot that high with no air seal lol

I should probably make more videos like these then! 🙂
@@anttechairsoft I wouldn't mind seeing more of these kinds of videos, as long as YOU enjoy making them
Great video!
Where did you purchase the spring?
That is a waterproof marine grease.
What battery was he using for 400 FPS if you know?
I have no clue what he was using to be honest... I just got it working lol
I just got this gun over the weekend, it chronoed right in at 425. I was running the factory 9.6v, but battery voltage wont change fps, only rof.
only on a nerf gun it would change fps
All CYMA guns have that blue goo in them.
What other CYMA's you've seen this grease in?
@@anttechairsoft every cyma I have opened. MP5, MP5K, M4 blue series, all the ones I have opened up.
@@pauls.5815 Interesting, I’ve only seen it in this P90. It’s all getting cleaned out and getting super lube at the end of the day anyway lol
