hey
i know this thread is about bigger birds, but my trex can get between 12-14 minutes...

it's all in the setup....

i have a very efficient, not a power hog motor, the 400dh and the 13 tooth pinion...

i run airthunder's 2200mah so i can fly till i take out 2200mah!

that's all there is too it boys

Thanks

I too can get 10-12 min on a 450 with a 2200 battery if I keep the head speed down and hover and slow forward flight until the ESC cuts out from voltage. But that's not flying hard or good for your battery
I get 6-7 min hard 3d on a 450 with a 2100 and put back about 1.75-1.80 (1750-1800mah) doesnt tax the battery that way and keep the head speed up for great flight, anything past about 80-85% discharge on your lipo gives poor performance and is hard on your battery.

hey
normally I would agree with the 85% rule but that doesn't apply for the Air Thunders and that is why I fly them...

that is why I can get very reasonable flight times...but like you said, that is mild flight with no 3D

Thanks

Never tried an air thunder, would like to see some times on mid to hard 3d with them. Even super hard to wild 3d time would be cool.

Alot of the issues raised here about flight times are using experiences from a very inefficient heli. The trex600 is too big for 6s and to top it off it has a very inefficient motor. As for the 500 it is offered as a 6s 2200mAh bird to try and get 450 owners to buy it and use there 3s packs in series. The battery capacity in this example is too low in my view. I agree longer flight times would be nice but there are much more efficient models to choose from. The Logo 500 with 6s 5000's would be a good example.

Sick of electric now, I'm going nitro. Just fed up with charging packs all night, and watching them slowly die over a year or so. Little 450's are ok but anything larger is just a pain in the wallet.

Warning...This hobby is very addictive and may damage your wealth

What kind of flying do you want to do?

Yep, you can refuel a nitro as fast as a stock car at Daytona, but your still sitting there waiting for the other guys to fly aren't you?

Everything said in the nitro/elec wars can be weighed and balanced by how your actually flying.

You really need to do the research and not rely on statements that are generalized, no matter how much degree of truth is inherent in the statements.
Lol...if we had television rights, our commercials would be worse then the elections!

I left the electrics behind. Just got sick and tired of 6 min flights.
I only had four batteries (hobby budget) and would use one up on the first flight just tweaking for the day and checking set up.
I used the 85% rule and could fly 6-7 min.
After the batteries were used up, I was done for the day.
If I got out early around 8:00 or so, I wouold be out of batteries before 10:00. Four hours later they are charged and I need to get home.
I feel the smoker is a better fit for my situation. I go to the field for one day on the weekend. (approx 10am to 3pm) I use 1/2 gal ($10) of fuel per weekend
I fly 20 weekends a year($200.00 for fuel)
With batteries, I would need four($480) to get 6 flights in the same amount of time. The eqaulizer is they should last two seasons, so no cost next year.

Plus.... I kinda like cleaning and checking things over.

this fuel vrs electric battle is different for everyone, I personally gave up glow powered last year and am glad I did. but I don't mind 5 minute flights, I could get 10-12 from my raptor 50 but generally flew 6-7 minute flights. In ohio the weather changes so often, I hated to do the engine tuning each day and the cleaning of the mess plus the hauling of the extra supplies, starter, box, fuel etc...... and I do most of my flying at home, so to lug all the glow stuff out back was a pain. (I generally only had time for 1 or 2 flights anyhow with the kids) so with electrics i can come home grab the heli and a extra pack in each pocket, go out back and fly 3-5 flights non stop, I can get in 20-25 minutes of actuall flight time in less time it took to get 10-15 with glow. when I am done I put it back on the shelf and I'm done, no clean up needed. after the kids go to bed I can charge my packs 1hr for my Lipo's and 15-20 minutes with my A123 packs.
on the weekend if I fly at home I can use my A123 packs and fly all day long non stop if I want. if I go to the club field, i start with my Lipo pack then put them on the charger and go to the A123 packs, by the time I am out of packs my Lipo's are charged. this year i will get a dc/ac converter so i can charge my A123's at the flield but for now I can't. I do really love to see a good 90 fly, but I have lost most all intrest in 50 size glow! I love my Hurricane 550 and now even my Trex 450 which got me started in electrics spends most of it's time on the shelf, the larger E heli's are much better,

As Concept1 says it is different for everyone. I have 4 10s A123 packs for my Logo500 and with the Mastech power supply I can fly all day non stop if I wished (or had time )

5min flight on each pack and I can charge two in 15mins. It makes the flight time a non issue really.

Can the A123 packs be charged right away or do they need some cooldown time like a lipo?

No you can discharge fully then charge right away at up to 10amps for 1p packs. The Mastech can deliver 20amps so thats two packs of up to 12s charged in parallel in 15mins.

I'm in the same situation I was all fuel for 20+years. I started with small electrics a few years back. Last month I sold my last 3 nitro's and all assorted fuel gear. I'm all electric and wont go back. I plan on doing a 90size electric this year. For those who think an electric 90 wont fly well look at these

No I couldn't wait an hour between flights so you just get more batteries and chargers and fly non stop.
Quiting nitro is like quiting cigarettes but once you do you fell so much better now I'm hooked on lithium

Fuel heli's will be obsolete within the next couple of years if Obama is elected. Carbon taxes on nitro fuel! How about $60 a gallon!

Looks like I'm gonna have to build a still out in the yard to make some NitroMethane fuel!
Seems like were into another one of those "Nitro vs. Electric" threads again.....
