Battery haters heli

Hey guys...

I haven't posted here in a long time and this is where I am now in the hobby...

I don't trust lipos at all and hate charging batteries of any kind so here's my Trex 700 nitro....










It has a 1900mAh 2S 3C LiFe pack that is charged in flight by a Jewel Generator.
No battery charging for this "Jewel" ever

I do check the battery every now and then and someday I will have to balance the cells....maybe

The battery initializes the V Bar but after it spools up,the tail drives the generator which in turn powers the RX and charges the battery.

I have it dialed down to 12 now but in that pic...you nailed it...It was 15 collective and 12 cyclic but that flirts with stalling.

I try to set up with 25 degrees or less with the cyclic and collective combined.

Wow, that generator is a great idea. I hadn't seen that before! I hate worrying about the battery being charged as these new servos really do eat it up. Also, it would help run all the FPV equipment I'm going to be installing.

However, I wonder how to start the heli when that generator goes right over where my starting rod attaches?

My generator is mounted in the tail drive so the starter nut is clear...I start it with an Align Super Starter like any other nitro heli.

Twice now,I've landed,refueled and plugged in the battery to find it was 100% dead.
That means the heli was flying solely on generator power on the last flight.
It wouldn't even light the LEDs on the FBL unit.

It doesn't charge the battery as fast since I put the AR7100R RX on it.
Still only uses 80mA per flight so I can fly 20 flights before the battery dies and if the battery dies in the air,I'll never notice until I try to initialize it next flight.

Those two dead batteries would have been two fly aways with crashes attached.lol...
