View Full Version : 3s in CX possible?
I have a 3s 450mah 25c lipo with a jst connector laying around from my broken pixy zap.
What would happen if I tried it in my Blade CX, would it burn it out immediatley?
Or would it make it really fast for a little while and then burn it out?
Or would it be O.K.,(I realize this is doubtful), but I just wanna mess around with the CX again, but at the same time I don't want to destroy it.
Anyone ever tried such a thing, if so how did it work out?

I JUST tried it and it is AMAZING huge amount of power!!!!!!!!! but the motors will only last about 5 mins of flight
spencer737 I think maybe you are kidding, but thats cool.
I just wanna try something stupid with my cheapest helicopter.
I have outgrown the CX, but I could still have a little fun with it.

Hi
The CX2 11,1v with 3-1 works perfectly. A lot of data here.

There are videos of people doing this, as far as I know there is NO problem running a 3s in the cx2 with the 3-1 it seems to handle the volts fine...
Thanks for the link, I think I will try it.
Just tried it, and it was cool, I left the front conopy off so the 4in1 would get cooling from the rotors. It climbs out rediculously fast now, and you can use aileron when you turn now. The piro rate is crazy, it was fun, but a little challenging to keep it from hitting the ceiling. I will post a video later.

That sounds SICK! would love to see the video!! :)

If you have an older 4in1 or a CX not a CX2 with the 3in1 it is NOT recommended to run a 3s. The 4in1 has been documented to NOT be able to handle the extra juice and will eventualy fry. The only people I know who have run a 3s regularly are those with the newer 3in1.
If you have a 4in1 and run a 3s its a ticking bomb, who knows when it will fry ;)

I use a 1000mah 11.1 v 3s batt in my Cx2, motors burnt out quick so replaced them with xtreame 180 ball bering motors and they handle the battery just fine. The 4 in one gets burn in to using the 3s after a while an wont work so well with the 2s batts. but after using the 3s battery who wants to use the 2s?

The 3-in-1 comes in the BCP/Pro, so it can handle the extra juice no prob! I have 2 3s 800 that I want to try now. Hopefully I don't burn out one of the motors, I just got the darn heli!

Well it works alright, but it cooked one of my motors!!! I ended up getting (2) 180 extreme brushed motors as a replacement, but have yet to get them dialed in to where I actually like them. Still getting a bit of drift and lacking the piro authority like I had with the stock motors. So, if you are considering running on 11.1, you do risk killing your motors.

See if a tail rotor motor off a Picco Z (micro x ETC.) might keep the electronics cool. I take the guts out of them to light up RTF indoor planes at night, lots of potential parts in those palm sized helis.

Have any heat sinks for the motors, stock or ball bearing?

I just installed the heatsink, 180 Extreme ball bearing brushed motors and metal swash all from HeliDirect. It doesn't seem to fly any better leading me to believe these are wasteful upgrades. At least they look nice! The one good thing I can say is that the motors sure do run cool. It could be that the heatsink is responsible for a lot of the dissipation, but I never got a chance to try it out on the stock motors. Speaking of which, the heli I got had motors out of a LamaV4. Are these the same size as the stock E-flite motors? Bigger/smaller?? Either way, on 7.4V, they work perfect, so if you're in the market for new motors, those are the ones I would go with because they are almost $2 cheaper. I'll try getting the 180's going a little better, but if they don't work out, I'll just end up going with a full brushless upgrade whenever I get some extra cash saved up. :)
