Which do you like better? Nothing quite like a 90 size heli... and nothing else quite like not having to haul around as much starting gear with an electric.

Just a question, how much do batteries to run a 90 sized electric cost these days?

I had trex600 on 10S which was comparable in power to a 90 nitro,
Much more expensive to get going with batteries costing $500 each and I had 3 for 3 flights. Then the balancing and charging which takes an hour per pack. I found that on warm to hot days I had to reduce the flight time to avoid the lipo from getting too hot like over 60 degrees celcius.!! Out of a 7 min flight about 2 minutes was at full power and then it dropped. Dont fly beyond 7 min or you risk over discharging the lipo, the temp jumps big time and the life of the cells are reduced considerably. Also the lipo temp jumps and can cause thermal runaway which means the lipo can get so hot it will begin to puff up and maybe explode. In saying that I have a JR Vibe 90 on the way. I did have a 50 but after flying a 90 machine there is no comparison and the 90 nitro delivers full power for the whole flight.

Hauling starting gear around

How much does it take to run a 90 machine?

Gallon of fuel with pump
ignitor
Starter system

How much does it take to run an electric?

I would suggest a 90 nitro, but then I've never had a 90 electric to compare it with! What 90 size electrics are out there???

My Logo14 will outpull any 90 I've ever seen. 14 degrees pitch with 7 on cyclics and I still don't need to know the meaning of "collective management".

fuel/battery

It is nice to know that with a glow machine I won't be destroying a large battery pack in a crash. Crunching a large lipo is like setting 12 cases of fuel on fire when you crash your glow machine.

I also don't like all the crispy charred helis I see in some of the photo galleries. Burning up an engine or clutch is one thing, but burning up all your servos, receiver, gyro, motor, esc, bec, etc.. during a fire is a little too steep for me.

And having 4 minutes of stellar power then the rest being average sucks.

Hauling starting gear

With an electric and some charged packs, all I need is the heli and radio.

With my Nitro, I'll take a 12V Optima battery, power panel, Starter, extra glow plugs, screw driver, gallon of fuel, charger for the Rx pack just in case it doesn't last, etc.

So maybe it's a little different for you, Tyler, than it is for some.

well, nothing beats the LARGE 90size heli whether it be electric or nitro. Personally I like nitro, yeah it's messy, but I'd rather spend money on fuel than on batteries that could be smashed in a crash.

These were from a members gallery, thought they were funny and yet appropriate, lol. Or maybe not....

...Once upon a time there were Nitros, flybars and frequency pins...

Sounds like you take the time to charge everything up for your electrics, but don't do the same for your glow machines? I charge my cordless ignitor, charge my cordless starter, and charge my 4800mah rx pack in the glow birds. This easily will allow for 12 flights without recharging.

Can you get 12 flights with an electric without recharging? Only if you have a gazillion dollars invested in fire starters (batteries).

Also, I feel safer storing fuel at home than I do storing lithium batteries.

I've got a R50 and a Rex 450 SE. Just got a R90SE and have yet to fly it so will let you know! I still think battery technology has to improve a whole lot before I'd get a bigger electric. I had a logo 10 a while back but sold it because I couldn't face the cost of buying multiple lipos!

Interestingly, a chap down our club recently *Invested* in a T-rex 600, he's done his math as well.
Turns out, if you treat thoes batteries well you'll get more cycles out of each pack than the equivelant £'s in tanks of fuel through a nitro...
I think he was reffuring to a 50 as well heh.
So its kind of like buying all yr fuel in one pack in one go!

The morral there would be treat your batteries well and you'll save yrself some monkey over fuel

But then again, its burning the fuel thats half the attraction to me
Wont catch me playing with electric *toys* heh.

Ps, saying all that, now i'm flying my hyper and flying more often, i can feel the niggle of having to buy fuel far more often...

Depends on how much you pay for fuel. I can get 30% for $15-$16 a gallon. At that price I would need to get 200+ cycles from a pack before the break even point. Also, the flight on an electric is roughly 6-7 minutes vs 10-12 minutes for a nitro so in reality I would need closer to 350 cycles for the equivalent flight time.

Also, the field support issue is overblown. I actually would need to carry much more to support an e-heli unless I invested in 5-6 packs and didn't need to field charge. At $300 a pack that's not likely going to happen.

Hmm,
Interesting...
But alas 30% costs up to £25 here, and it seems people seem to be able to get Trex 600 batteries for around £200...

Maybe the statistics are slightly buggered up because it'd be worth importing a battery but not 10 crates of fuel...
