its supposed to move back, sadly that means its busted. I had it happen to me... Luckily MLEmart sells them for around 30 dollars!

Progress and details on this build is on my instagram.

​@@wyshtechairsoft Thanks man, I will check

Definately. Ive had it pull a m170 no problem.

Range. Heavier bbs carry thier momentum longer than lighter bbs.

You're absolutely correct but this video was to keep the rifle 1.5J or lower and STILL be able to sufficiently shoot .40g as you cannot shoot a .40g bb without proper air/volume ratio adjustment. Which in this video was supposed to show how that works.

When you say "bull tooth lifters" did you mean the bullgear tappet plate? Metal nozzles are more reliable in my opinion as they do not get damaged when you have a bb jam and these MP7's are prone to jam at higher rate of fire.

@@wyshtechairsoft YES ! bullgear tappet plate .

Thanks for the support bud! Are we talking about Ben C?

​@@wyshtechairsoft nah Ben M

Thank you so much for the kind words my dude! Comments like this inspire me to do more.

Can you elaborate more? I'm not entirely sure what you're saying. Just want to make sure we are on the same page.

@@wyshtechairsoft so you have play left to right on the gear however that play is just in the races of the bearings. Meaning there is no movement of that axle in the centre bearing race. That’s best case but depends on size of shims you have available

They stayed intact until they came out of the P90 and hit the inside of the chrono box. haha. Or did you mean something else?

PME means Pre Mature Engagement. It's where either the piston OR the tappet plate gets picked up too early and causes failures such as damaging piston, gears, bearings (if installed), massive drop in fps, horrible fps consistency, etc. I dont have a video about it yet but I recommend searching youtube about "airsoft pme". There is some damn good videos that explain it in depth.

Good guess!!

@@wyshtechairsoft thanks a lot.

@@Antre_du_Dingo No problem!

I typically use a Li-Po (NOT Li-Ion) GNB 11.1v 30c/60c 1500mah. I sell them on my website if you're interested. They provide excellent discharge so much so that Ive seen up to 5 rps increase vs other brand 11.1v LiPo of the similar spec.

.3mm of spacing is a bit excessive in my opinion. I always shim no higher than .2mm, typically .1mm. Then make damn sure theres .2mm spacing between the gears AFTER I shim bevel to pinion. Works every time!

That's the stock gears and microphone amplifying the noise for ya. I could make it better if the customer let me install Wyshtech/JVAN gearset and pinion.

@@wyshtechairsoft​​⁠​⁠​⁠​​⁠​⁠Copping out with saying that if the customer got your specific gears it would sound better comes off as very lazy at best, and incompetent at worst. A decent tech would and should be able to shim stock gears decently. Audio quality excuse is lame, it should not sound that poor with and without the precocking even with a crappy microphone

Your comments always crack me up ("Tip 1: Dont buy it.) but are good information for the new techs. Thanks for your insightful comment. :)

These a great questions! To better help you with your questions. Hop over to my bio and join the Wyshtech Discord! Copy and paste your questions over in the #airsoft-tech-help channel. Thanks for watching and your kind words dude!

Absolutely. LOVE this motor!!!!

It's what I had on hand at the time and I could get it to exactly to where I want it. No, 1mm wont make any noticeable difference. Its what I ended up with when I cut it down. Margin of error, if that makes sense.

Should be no problem. Wyshtech.com

@@wyshtechairsoft out of stocks

The quick answer, No. Your goal is to match your air volume of your barrel vs your cylinder COMPRESSION ZONE volume to the weight of your bb. I highly recommend reading this article about the "What Barrel Length goes with what bb weight in an AEG?". Link: www.airsoftsociety.com/threads/what-barrel-length-goes-with-what-bb-weight-in-an-aeg.153191/

@@wyshtechairsoft the article says about 6.03 barrels, i dont know if using a 6.05 barrel would make diference, and about the 1.5 joule question, i would like to know if a .32 performs better than a .40, in my 1,8J SR25 im using .40s in a 420mm 6.05 barrel

Quick answer, I find 6.03 x 410mm with a SR25 length "NON-PORTED" cylinder in the SR25 is the sweet spot for .40g for best accuracy and maximize range without pushing TOO much air. I highly recommend reading this article about the "What Barrel Length goes with what bb weight in an AEG?". Link: www.airsoftsociety.com/threads/what-barrel-length-goes-with-what-bb-weight-in-an-aeg.153191/

I honestly dont remember. It depends on the field that the SR25 is intended to be used in. I find that Matrix m120's get about 1.7 to 1.9J on .40g bbs since the SR25 can joule creep very easily.

I've been able to put the Maxx VFC Scar hopup in one and got it working. It was awhile ago but you MIGHT have to change to a different length nozzle to get it to feed and shoot correctly.

Those gearbox shells can handle ALOT of stress. Ive got one that shoots 55rps at 1.5J with no issues with the shell. The Perun P90 ETU makes it possible but I have to run the Maple Leaf Super Feed spring in the mag so it can keep up on feeding.

Its a proprietary offset.

@@wyshtechairsoft what a shame, would have gotten one to throw in a polarstar f2

@@belaklosterlein7506 you can, you just have to 3d print a custom chassis. Im going to convert one to hpa.

Thank you for the advice! Maybe ill try some dry lube and see.

Yes

170 euros is fucking STEEP

Yup.

I plan to make a video about the solink mp7 brushless motor at some point as I DO have the motor. Just really hard to find time to record more videos.

I finessed the wiring and found that straightening the wiring the best you can and keep pushing the wiring against 1 side of the receiver, feed the wiring through while you push the lower receiver into place.

Any TH-cam video on disassembling a V2 gearbox / M4 platform will show you how. (Since the SR25 is basically the same, just longer) If its a cyma platinum SR25, with the addition of whatever disassembly video you watch, you have to remove BOTH selector switches, spring guide, AND bolt release.

Thank you!

Got em on my website! Check it out!

Nuh uuuhhh!

Have you noticed any back spin ?

@danorlando3503 nope. None at all. Its literally as if there was a ARL. I got the motor in my dmr and it runs quieter now AND smoother.

@@wyshtechairsoft that’s super interesting! Do they have a rating for input delay ?

Either theres an electrical problem or did you throw in any upgrades that make it cycle faster? Join our discord for more assistance!

That piston makes the rifle sound smoother.

Right on! What do you think of the motor so far?

@@wyshtechairsoft it’s pretty awesome, the braking is def superior to the t238s with the unidirectional bearing which also helps with making it more consistent. The amp draw seems to be a bit higher than t238 even when adjusting the “torque” option (I’m convinced it just limits the starting current pulled by the motor). I feel this is in part due to the motor now bearing the load of the main spring constantly rather than having a arl take that pressure off. But overall I feel it’s superior due to its more precise piston positioning, braking, startup, and programability. Currently in my setup with the motor set to max “torque” and 35k the semi response time is 18ms on 18:1 Solink helical dsg gears which was an improvement over the 23ms response time of the t238 33k I had previously. Sub 20ms semi on anything not 14:1 dsg or lower (excluding precocking) is very impressive.

@jhqtech Wow, thanks for the insight! How do you measure the response time?

@@wyshtechairsoft sound meter+leviathan readings then just average the two. It’s probably not perfect but close enough

@jhqtech How do you do it with a sound meter?

Thank you for your input! Makes alot of sense. If you haven't yet, you should join our discord! Link is in the description or in my bio.

@@wyshtechairsoft Sounds interesting, I'll check out. I wonder if you bring tht T238 up to same RPS how the AMP draw would change. If you're curious, compare a Neodynium magnet high torque with a stock ferrit motor, at stock spring power the AMP draw of the stock motor is also lower so AMP isn't everything, it's a all related system.

Maybe I can do a quick youtube short?
