Hyperfire Lipo mod.

Hello fellow Nerf modders lol ( which is probably everybody )
Right I'm in the process of doing a full out Rapidstrike build but due to waiting for parts it's come to a grinding halt !!!
So basically I've got itchy fingers so I have a completely standard hyperfire sat here in front of me and although I don't have anything for the hyper I do have wire and a few Lipo's so I feel a basic rewire and Lipo install.
But now for the question and the reasons n for this post, hyperfire standard motors what voltage is best 2s or could they withstand 3s voltage?

Er, the Hyperfire is horrible to mod. We tried the standard LiPo/rewire build and it had horrible results.

The belt drive on the feed mechanism really struggles with anything more than 6V (even the RPM on a 2S LiPo was too much) leading to skips, mis-feeds and general slippage. If you're using a 2S LiPo then get some BY-500-800 diodes and wire 2 of them in series on the positive pole of the pusher motor to bring them down to nearer 6V and a more stable output.

On the front end, the motors don't mind 3S but again at 2S we had a lot of problems with whirly birds due to those canted flywheels. It would seem that canted flywheels need to be tuned to a specific muzzle velocity or Hasbro got it wrong. I'm currently working on a way of removing the cant from them so we can upgrade the damn thing. This is the only platform I would actually recommend Honey Badgers for because it looks like it actually needs 2S.

Of course, prove me wrong but we did replicate these problems in 2 different blasters. Smile

I've not got round to modding mine yet so it's just running on 3 IMRs, total bodge... Obviously not directly comparable with a proper lipo build, more voltz, less ampz, but apart from the smell it's doing just grand. I might packhack it at some point to see what happens.

I think when I do it properly I might see about fitting a different flywheel cage but that's a ways off. TBH I'm more of a fan of the hype than most folks.

Oh balls !!! Well that's not what I wanted to hear lol, will have to bob along to my local Maplin me thinks for some diodes!!

EDIT:

So Boff apart from the pusher motor/belt issue did you get better results from the flywheel motors on 3s?

EDIT

Please don't double post, edit your previous post. -Boff

2IMRs... all the trouble the Hyperfire is worth. Just sayin'.

It's that bloody belt drive causing the issues I think!!

Try a brass or petg dart guide through the flywheel cage. That should fix the issues. Also, concave flywheels should help, too.

Yeah I realise that would improve accuracy but it's the belt itself I'm looking into now. The teeth aren't very large so easily skip over darts that aren't in good condition and more so at high speed. Need a belt with better teeth, so I've put the feelers out to a couple of our belt suppliers at work but not expecting much from it really due to size of belt.

I've a feeling mine might end up with a rapidstrike pusher or one of those stryfe pushers in it. And a different cage. I just like the shape tbh  Laughing

Look at Blastaway,eu's video on the Hyperfire. That looked like I would feel comfortable trying it..

Had my Hyperfire modded for a while, sadly I do enjoy but it is not great. I have done a fair amount of playing around but nothing solves the whirling bird issue (2s, brass, etc.) so would say it does need a new high performance cage in it to get it working.
Boff

Yeah, I'm just going to print a whole new, non-canted cage for it. Sadly, the ergonomic car crash means it's right at the bottom of the list. I really couldn't give less of a shit about this sack of crap. Very Happy
Waltzz

ha yeah I agree. This is why mine is at the bottom of a box.

Maybe if I have nothing else to do, I will revisit it but money on a new cage seems a bit pointless when I have several rapidstrikes that already out perform it.

Apparently taping the wheels in the pusher mech increases feeding reliability.

Sorry not following how do you mean taping, in what way exactly?
