Unless you've got a higher-end set of calipers coming then you might not get an accurate reading. I went through a few from £5 to £25 in the end had to spend £150 on a decent set. I highly doubt any brand would want to go bigger than 5.95mm. My guess is they aim lower for better fitment. Most BB's I measured this past couple of months were 0.01mm lower than stated. Some brands do state +/- 0.01mm. Heard tolerance is a bitch with injection molding. In regards to your high FPS did you change anything else?

@Sewdhull check out coconut airsoft on FB, interesting stuff he did with a 45k motor

@Leo Greer yep, should not be generating too much heat. 25-40C ideal battery . I read an post about a guy who used a 75/160C drone battery and it melted the PCB traces on the controller, understandable as that battery will kick out a huge amount of power. As soon as things calm down I'm going to get myself some more batteries and do some heat tests on some different builds. Just slammed with work at the moment

@GiantKiwi why do you think that exactly? how much are you thinking and what area? I'd say yearly pen test / audits would be a nice bonus but "significant" I'm not so sure

@superwok I know you got it sorted via the just-cos route, however did you not try to ask any retailers if any other forms of defence were acceptable? You've got 110 posts on this forum, have been a member for 5 years, visit regular and have 100% feedback, that should be enough to confirm. As @Dan Robinson also states, social media posts / photos also another good. The IT ex-colleague of mine who's still looking at a defense system (has a fair bit of it built) was thinking about putting in supporting material for defence, how it will work in the system I don't know but seems a legit idea.

XT one uses UH grade magnet as well, my guess is they all do and it's nothing to get hung up on. I like the toggle switch of CH though, less for the customer to fuck up!

@Colin Allen thanks, i've got a epg-c one here I'll give it a test. Also have one of those from an old g+p magpul so i'll try it out.

Factory just sent the stats over to me, not had a real chance to go through them yet:

Ahh right, has it got a different style of grip? Could I trouble you to post a pic of it please?

@Colin Allen Are you fitting it to a SCAR ?

thanks for the feedback on the grip base plate, I'll add that to the description. I have more motors but for now I'm holding them back and waiting on more feedback, just in case.

Just tested the RPM of the test Brushless motor, 11.1v Turnigy 15-25C (Battery around 85% full charge) Fast = 34K Slow = 30K Only 12% difference give or take with a 11.1v 7.4v Turnigy 15-25C (Battery around 85% full charge) Fast = 20.5K Slow = 19K Hardly any difference. Full stats coming Monday fingers crossed. I also got some Perun's in stock so I'll be able to run some full tests with one of those.

thanks, let me know how you get on. I'm still waiting on the factory to give me the specs for this batch, however this weekend I've got a little time so will do my own no-load RPM for both speeds.

that's wonderful news. The flat little boxes are a godsend. 90% of the orders I have can fit into a Large Letter box, this allows me to keep the fee for Tracked 24 to just £3.30 (Royal Mail price rise imminent) plus you don't need to be in when the post arrives. I could save a buck or 2 by going down the jiffy bag route like most other retailers but nah keep it boxed....

@Pseudotectonic Not sure on the magnet prices but traditionally in brushed motors this was always the biggest single cost. Windings and thickness of wire can be flexible from what I know. The integrated tower is a nice idea but you'd also have to make a new MIM body for the brushless, this would be a huge cost, would need to open a new mold etc. The "dumb" motor is a really good idea and could help in lowering the price however from what @Sewdhull says it needs a certain level of intelligence in order to function. However there's no harm in asking the question to the factory.

It's possible on most, winding counts and magnet a definite yes, position of bearings hmmmm not sure, where are you thinking? They're a RC motor factory and this is their first venture into Airsoft, my guess is a fair amount of the components they buy from a factory. At the very least I can ask and they will say yes or no, or that will cost £££ extra. At the moment they have only just got back from their new year break so still waiting on the full specs. My overall aim is to have a reliable brushless motor under £80

Photo of the innards today, my test motor had a faulty bearing after I applied too much force when initially fitting the pinion. Seems the worst thing which will happen is the rear bearing will fail and cause the performance to degrade, pretty simply fix.

@Sewdhull thanks for the amp test, I did do one a few months back but someone else doing a test would be most appreciated. The overall length when they came from the factory was a smidge longer than I liked but really I don't think it matters too much, I might just send out the ones I have left out at 88.6mm, on the 2nd batch maybe reduce the length to 87/88mm XT= 88.6mm T238 = 86.3mm Warhead = 87.8mm SHS = 88.1mm

@Fatboy40 I'm still a little concerned over why it wouldn't work with the DE Falcon, I don't have one here to test myself so might try getting hold of one. I remember seeing a YT video with the Warhead on a M904 and it worked ok, apart from the 7.4v wouldn't spin I think, also the motor was a little too large for the grip.

@Fatboy40 hey mate, I've seen on a few other video's that with certain grips you have trim a little of the motor plate. I completely forgot about this so will add a mention on the description. What battery are you using with the Double Eagle? It's it's 7.2v maybe try a 11.1v If you don't have any joy with it just message me and we'll sort out a return on it. I'm offering all people who are in test this option.

thanks man, I've been tested each one before I send out and I think they work so well due to the higher polishing that I paid extra for the factory to do. I want to do some more video's on them but it's always windy or raining so might have to wait till the spring. I've now got 6.01mm on the website, they're about 20% more expensive but seem to offer the same performance. I had to drop ZCI inner barrels, I was getting so many reports of BB residue build up that I wasn't confident with them anymore, plus on a couple of inspections I found some shocking flaws. I've made a video and will upload it in the coming weeks but it's an eye opener.

then after someone breaks it send it to Stevfix 🙂

If I get some time this weekend I'll desolder the control board, plus break out my tactometer to get some RPM readings

I recommend no AB or pre-cock for now, I'm out of Perun's at the moment so can't run any tests, as soon as my supply gets in I'll test. For anyone desperate to run those I suggest waiting till the 2nd batch arrives (if indeed I do decide on a 2nd batch). @strykerles Yep the plan is on for shorts. Super easy to convert a long to a short if desperate enough No capacitor that I could see

@Pseudotectonic it doesn't spin when the button is depressed, however if it was me I'd simply remove the motor, connect it to the wires, then set the speed. it's not something you'd be changing on the fly really.
