I have been contemplating getting into larger 600 sized heli, but my friends who are extremly talented say the flight time is terrible. What is the truth, I have tons of quality lipos up to 12s so the cost is not the issue performance is. I probably have enoung battery power to opperate my house for a month. With that said I like the convenience of electric, but in high performance machines what is the rue flight time?

Trex 600 mid to hard 3d 6+min on 6s5000 12+min mild 3d/sport 6s2p6000

If you have enough packs and chargers you can fly as much or more per hr as any smoker! and 5 or 6 min hard 3d is enough for most and ready to land and take a short break and unlike fuel you can simply change battery and fly again no refueling and starting (or cleaning)
I have flown fuel for 25yrs and last feb at Monroe RC swap meet I sold my last nitro powered aircraft including all starters and tools for said smokers. I am now 100% electric and not looking back I now have 6 e helis 400 450 2-500 2-600 and planks with 12s and 15s setups.
ALL E ALL THE WAY!

I do mild 3D with my Trex 600 and the timer on my tx is set to 6min 30sec. I land when it starts beeping and usually put back in 3600-3950mah. Running 6s5000. XL motor 10t pinion.
When I say mild 3d I mean some slow paced inverted stuff mixed up with FFF in between.

im running the neu 1515 2.5 dfh on 6s in a trex 600 and it has awsome power. you can fly all you want if money is not a problem. i normaly get 5-6 min of flight time. having lots of batteries is good, but you need 2-3 chargers and balencers to charge them without it taking forever.

Just buy more nitro! 9-12 minute flights. Land, refuel and back in the air in 2 minutes. No charging required.

And I'll wager a bet that you can refuel and restart a nitro in a lot less time than it takes to dick with a canopy to change batteries on an electric . . .

I have both a Trex 600E, 600N & Kinetic 50. I have yet to run a full tank through the 600N, but I get about 10 minutes on the Kinetic 50 w/a Hyper OS 50 engine. I get between 12 - 15 minutes of normal flight time on the 600E with the stock 600XL motor. I am using 6s2p 4600 & 5000 packs for the 600E.

I find myself grabbing to the 600E & flying that much more often than the 600N & Kinetic 50 since I don't have to fuss with fuel & starter. I am often pressed for time though.

Man I love the NITRO ELECTRIC wars
See it every weekend at the field. funny thing is there are more and more electrics and fewer nitros as time passes. Especially with the heli guys!
I remember when I said electric performance will never out pace nito/fuel. well boys the day is here and its only getting better. even the giant scale planes ar going Electric
I saw one at a show last fall with 16,000 watts of power. cant remember the exact watts/HP # (but its like 760+or- watts per hp)so that over 20hp of smooth,instant,clean power WOW few more years and battery technology will get the run times equal to and probably higher than fuel. Oh ya and I just saw a gallon of nitro at the LHS go over $30. Fuel prices getting higher battery prices dropping.

The hard core nitr/fuel guys will come around, I did and just to let you know I'm 47yrs old and been flying since the late 60's with my dad who at 69yrs old and just got an electric plane

I wouldn't bother. I had an electric 600 now have a nitro. short flights and long long recharge times. You may get 12min flights but that will not make up for the hours of charging you do. I would have had to pay around £1700 ($3500) to get the same days flying as I do with my nitro. The worst thing is the batts don't last for years, for the price you pay they should.

12-15 minute flights on batteries on 50 sized electrics? Must be some killer 3d hovering at 1200 headspeed. Come on. We all know 6 minutes of real flying is the reality.

Had a 600E sold it and built a 600N.

Electric Trex 600 would only run for 4:30 seconds on a Thunderpower 5000 pack and 100% throttle curve. The performance was amazing for the first 3 minutes of flight and then fell off towards the end of the flight.

The 600N gets 7:30 seconds on a tank with another minute of autos and hovering. No need to worry about expensive packs and over discharging. I would rather spend 20 minutes wiping off nitro than 5 hours charging.

I would still like to try a 500 though. It might be the perfect blend of size and power for electric. And one thing is certain, the 600E was smooth.

Good luck with your decision! Either way flying is great!

IT's what I do.

Geesh, only if the heli is "underbatteried". My Logo 14 has full power for 10 mins at 2000 headspeed. But I'm also carrying about 40% more battery then a typical T-Rex 600 and my L14 still weighs about a good pound less. That makes a big difference.

IMHO, the T-Rex 600 is simply underbatteried in its "stock"/"typical" form. That was clearly a decission made to try to keep the appearance of the battery cost lower. But, what did it do but serve to "prove" to the nitro only crowd that electric is not ready for 50-size and larger birds.

Anyways... There ARE ways to get perfectly exceptable flight times on 50- and larger size electrics. If a heli is only getting 4-6 mins of flight, the heli is clearly not carrying enough battery.

Jkos you make a lot of sense and as floop said I would be willing to try the 500, if it only got more than 5 minutes. These larger helis are "underbatteried" if that is a real word. I tried many different (very expensive) things to get more flight time but I just kept ending up with more power. Which of course is fun, but only for 3-4 minutes. If someone will find me a nice 500 sized heli that can go 7-9 minutes I'll take it.

I don't know if it is a "real" word, but I'm not the first to use it in this manor.

Put a "T-Rex 600" battery in a Logo 500 and you should easily be there. Seriously, a 6S 5000 does extremely well in an Logo 10/500 heli.

or look at the Gaui Hurricane 550, I have a very nicely powered 550 and I get 4.5 minutes on a 2500mah 6s pack, or same on 7sA123 packs. so 7-9 minutes are very doable on a 4-5000 pack, I am sticking with the 2500 packs and A123 cells though do to cost! I can swap out my A123 packs charge in 15 minutes and fly all day long if I choose, the A123 packs cost me only $75 and 3 packs will keep my flying all day, or 2500mah lipos are about $160 still not bad.

when i had my vigor cs, i was charging it. i had two JR 4500 mah packs that would not last all day. just those two packs were 100 bucks. i had to charge those for 30 min or so, so i dont see a big deal in an extra 15 min to charge big electric packs.

-------------------------------------------------------------

T Rex 500 running 6s1p 3000 (3200 is what the cells are) 13 tooth pinion,2620hs, mid to hard 3d. My timer is set to 7min and I put back 2300-2500Mah could go 8+min easy. I have 2 of them and the 2nd one was built with the battery tray mod and I can fit 6s 4000 batt for 10+ min flights. I am now 100% e power and wont go back

Century Swift 550 6s1p 4000 7-8min hard ArmsMaster just sold it to another Buddy of mine to get his Trex 600e.

Armsmaster has a trex600n and 600e he flies the e more but wont give up his nitro 50. He also has a 90size nitro, and a T rex 500. He is as hard core of a nitro guy as I know and even with that he loves the power, performance of his electrics. As with many hard core nitro guys he says he will never give up his smokers, but I suspect that as the price of fuel goes up his batteries will get more and more use It happened to me it could happen to you

Thanks for the info talegunner. I've seen several 500's at various fields and the guys are all complaining that they are done after 4 or so minutes, that's why I didn't even consider purchasing one. Otherwise it's a great looking heli and looks like it flys great as well. I think Align does much better on their electrics.

If you run 2 2100 3s lipos from your old 450 you will only get 4 -5 min try a 3000 3200 or 4000mah and get great times. also with the 12 tooth pinion its still not in the optimum efficiency of the motor the 13 tooth gets better flight times and higher head speed.
I made 2 8 min flights today on mine mid to hard 3d with 3000Mah maxamps 6s1p and replaced 2460Mah on 1 and 2535Mah on #2
