Hey guys. im back again
So i still have my M4 with a 13:1 gear ratio (Still unknown spring.) but i know shes hitting 300 fps.
At this point of time i have a 35k warhead in it. and shes pushing around 27-28 RPS. Would it be over kill if i slap a warhead 45K into this. My hopes was to be sitting at 30 rps but it seems to be slower compared to my old boost 40k which was sitting at 29 rps.
I do not know what the calculations are to figure out what the fps would be with each motor
According to a spreadsheet I have from tha a/s peoples, a 45k brushed motor (14tpa) would give something like 40.9 rps, wheras a 35k brushed motor would give 35. rps.
You’re not using brushed motors, and you’re not getting the rps that the results would suggest - but regardless the ratio/difference should give you a better idea of what to expect.
I have a warhead base 35k and 13:1 short 4 teeth with m120, and it pumps around the 35rps mark. (350fps)
Had built many 16:1 and 18:1 boost 40k builds and they all hit just on or under 30rps.
I would nearly guess you have some electrical and or mechanical resistance somewhere. What plug, wiring and trigger switch are you using?
Also what blaster and gearbox?
Also if you are around or upwards of 30rps you should know what spring it is, or at least have some short stroking to mitigate potential pre mature engagement issues.
The other question is what mags are you using as not all can keep up beyond 30rps and you might actually have higher rps and it is dry firing at points. Easy to tell up to around 25rps but gets difficult to hear a dry fire from 30rps and up
apologies for the late response.
When i got the blaster modded. I told the store what i wanted it to do and told them to put in the appropriate parts. So sadly i dont know what spring they put in due to they never actually told me.
It has silver wiring with deans plugs that run via a leviathan mosfet. Nothing inside the blaster is stock.
I have actually put the 45k motor into the blaster now and its running at 32 rps with no issues.
could you possibly send me the spreadsheet? I have some friends and family asking me in regards to their blasters what sort of rps they would get with different combinations.
32 rps seems low for a 45k with 13:1s. I’ve got 12:1s and a 25k 26tpa and I get 31.33 rps?
I know this is what the thread is about but what spring are you running? I feel like brushless shouldn’t have an issue with most springs so could be a shimming issue?
edit: fuck this is an old thread oops
its fine, i still get notifications for this. Unfortunately, i dont actually know what spring was put into it due to i got a shop to custom make this blaster and they never ended up actually telling me what they put into it.
Awesome to see that it doesn’t matter how old the thread is……., as long as someone here is willing to still comment and help out 
Thanks…… I still stand by my own comments above 
Here we go. Very old thread at this point. But yet again, this fucking blaster fucked up and i gave up with the store that was working on it.
I pulled it apart and found out that no. They didn’t put 13:1 gearset in it as i requested when i first got it. Instead the original guy that made it put 18:1 gears into it. (he liked HPA over anything else and what i been told by people who worked there. He didn’t care and did whatever he wanted)
Feel free to post pictures and ask for advice here mate, there is plenty of experience here to help out.
Sounds like the work of a HPA fan, they’ll do anything to convince that HPA is the best… despite AEGs being able to match or beat them with the right parts skill and experience, they love carrying their scuba tank and want others to suffer the same.
It’s disappointing to hear they did whatever they wanted, and not what you asked them to do. They might have reasons but it should have been discussed with you throughout the job.
What blaster and brand do you have?
im getting all the stuff i need for it now. just waiting for the piston and the shims to come.
GBF Black Widow CNC box
35k base warhead
13:1 gearset (2 teeth knocked off)
hybrid anti-reverse latch
levi
Azreal CNC rack and piston (the one in it at the moment broke again)
Apache
M110 (i believe it is. atleast thats what it feels like)
SLR ion CNC reciever
LDT T-piece
Optac barrel with internal hopup
It was originally a wells. But only two things still stock is the buffer tube and the pistol grip.
Two things im aiming for and i predict: 35-40 RPS
300 FPS
the owner of the store was a HPA and speedball guy. he dropped everything else to go work on that stuff. even if the AEG he had in was sitting on the bench for about 5 months
All that should work, should get 36-38rps too, right where you want it.
Normally that motor and gearsets I go for 4 teeth off and an m120 spring, but not many gearboxes are safe with that sort of spring. Mainly as with higher rps you don’t want the risk of a jammed gels and an m120 will power through it.
Also want to make sure the nozzle moves very easily, in this sort of build it is worth a small drop in seal if it means getting the nozzle moving fast… you can get both with right parts or work though!
Should be a beast!
didnt get that notification sorry
In theory and based off of what i been researching. an apache with a m110 spring should be perfectly fine for what im running. Im not risking running a tappet plate. i will keep testing with short stroking but i believe 2 teeth should be fine being knocked out. but we shall see.
Waiting for the agony of all the parts to arrive now
Last update for me
After pulling this thing apart. There was literally rocks in this box. The grease didnt look good either. thick and horrible. over everything. i suspect it was TechT Gun Sav
The gear set was actually 16:1 with 2 teeth short stroked and a m110 spring i believe.
im sitting at 33.3 RPS at the moment still awaiting for my new piston head to arrive so i can replace the fucked piston. there’s a couple of things that i could of done to make it even better. but i’m happy with how it is. Extremely snappy trigger and with 35% pre-cocking, its instant trigger response.
