Is there a way to tell what firmware is on the DUO without hooking it up to a computer? Im asking because I want to buy one, but the store doesnt know what firmware is on it. They said they just got them from their distributor, if that helps.

Thanks

Probably not unless you actually have it in your hands - it shows it on the screen on startup.

Thanks a lot! I will ask them if they can check for me.

If their distributor does a volume businessin hyp chargers, it should be v1.6. Several places that sell them are advertising v1.6.

I did the update and it worked fine. It wasn't that fast but maybe that was because I was using a slow old usb1.1 laptop. I used the charger for the first time to charge lipos and it worked well. Much quicker then my other 50w charger.

I ran the Hyperion Y22s 6000kv in my M18MT with my stuttering quark and I was very surprised to see that the stuttering had almost completely disappeared. I have no idea why but I like it as I can now use the Mamba 6800 and micro pro in the mini-t and the quark and y22s in the m18. Sammus I can check the fit of the y22c in the mini-t for you if you'd like. I don't see why it wouldn't fit other then you will need to dremel the motor plate out for the mounting holes on the motor. The protruding bearing carrier doen't stick out as far as some motors either.

What is the difference between the yc22s and y22s? I know the yc is for cars but what have they changed?

sealed endbells for one. And I'm not sure if the y22 does, but a lot of air motors that size have a 2.3mm shaft, the yc has a 2mm one.

Sealed end bells would be nice. I bought the y22s and I was just going to electrical tape the holes. The shaft fits the m18 pinions perfectly so I assume it's the same as the castle one.

The Yc can is enclosed like the Tekno Neu while the y22 is open...the Hyperion motors were originally made for airplanes like the Neus

O well, nothing a little electrical tape can't fix.
