Great power switch for T-Rex700 Nitro

Up to now I have been having to take my canopy off before and after each flight to unplug the battery since I have it connected directly to a Spektrum AR7100 receiver that comes with a "soft switch". But the soft switch still allows some voltage to pass thru and be consumed as I can see some lights still on some devices after a flight when I flip the spektrum soft switch to the OFF position.

I was hoping to make a break in the battery line wire, and connect a reliable ON/OFF switch to the chassis by breaking this connection so all power is turned off (or ON) without having to take the canopy off.
Anyone know of a great reliable switch for a 6V to 8V battery power for nitro heli's?

I don't want to use an Align 2 in 1 as I have no use for the voltage regulator with the AR7100 receiver; and I have a glow-plug remote for the glow-plug connection already.

the best thing you can do with the 7100 it have the extension and the charge plug that shuts off the reciever, there is no way it could ever fail unlike the soft switch, also you can charge thru it so you do not even have to take off your canopy.

Good point! I hadn't thought of that since I charge my packs away from the heli.

Thank-you.

Bet you money that was the 2S lipo that comes with the Align 2-in-1. If so there is no way I would use that lipo, it's known to have issues. Mine starting puffing just sitting in a draw still brand new, I immediately disposed of it!

For the record, I've always charged the battery mounted in my heli. I've always used quality packs, quality chargers set to the correct mode, and never had any issues. I've also never seen anyone else I fly with have issues. These incidents like above are less then 1% of the big picture.

a lot of times i leave the battery plugged into my 7100 receivers and have no problems, I may lose 10 mah every couple days but there is no noticeable difference from a full charged pack that i leave plugged into my heli and put back on charge a few days later.

PIC THIEF!!!

Those are my pics, my buddy Alan's heli. This was due to a crash, NOT charging error. I did not see the crash, but the fuel tank AND lipo were broken open in it = ignition source and fuel for the fire. Alan is never gonna give Usain Bolt a run for his money, so by the time someone doused it, the heli was gone.

As far as the switch: Go with "trickytiker's" suggestion. My three nitro helis all use the AR7100R with Arizona pin-flag switch. You can see them in my gallery (minus the 600's flag). Works great, will always tell you whether the heli is on or off, and cannot fail in-flight. The only downside is that you have to re-connector the switch to a servo lead, but do it once and never think about it again.

One problem

If while your heli is in transport and you have the bad luck of having the pin fall out accidently. Blades are locked in the holder, Puff there goes your high doller cyclic servos.
I still unplug my battery till I get to the field.

Blades are only engaged when they receive a lock from the transmitter

At least that's how it works on my FAAST system

Here is a almost perfect answer to your need, look at the Badger Switches. They are available in either slide switches or pin flag switches. The also have a built in charge jack.

Feel free to PM me with any questions regarding their products.

the idea of a pin switch is you don't have to remove the canopy and i would rather make one for 60p than buy one when you can get them in the uk for £7.00 and very quick to make

NO SWITCH

run a LipoFE (a123) 2s2300 pack directly into the RX.

Charge it at upto 4C in about 10 minutes, plug it into the RX, fly for 5-6 flights, check your cumulative mAH used...

cheap, no switch to fail, can take high charge rates, durable cell design.

If you're running a tail servo that can't take over 6vdc, run a drop-down diode in series and you're all good - OR - run all 6vdc+ capable servos (JR 8717HV, MKS brushless, DS or HV series, Align 6-series servos).

so, no switches to worry about, no fires to worry about, no regulators to bother with, just simplicity.

if you leave it plugged in i'd hope you'd notice your servos jittering, especially when you pick the model up to pack it away.

Powerpole Jumper

This is on my 600e's main battery, but the same concept would work for flight packs on nitro or electric. Note the extra "parking plug" I've attached to the frame, so I won't lose the jumper.

jesus1895, I'll stick with the Powerpoles, thanks. The jumper technique would work on any connector style of your choice, but I will point out that Powerpoles don't require two hands.

I was not intending to start some lame what-is-your-favorite-connector religion debate, those are really quite boring.
