I'm sure this has been covered but I can't find it. I'm just wondering about the difference in fuel consumption between a 50 and 90? Also, for general sport flying do I really need to run 30% nitro? I'm obviously having a debate with myself trying to figure out if I should go 50 or 90.

If your lucky you'll get about 8 flights per gallon with a 90 running on 30%. The 50 will give ya about 12 to 14.

The ninety would be the way I'd go.

On a 50 size nitro with a OS 50 Hyper,you'll get around 8-9 min's per flight and 12 flight's per gallon..
On a 90 size nitro,you'll get around 8-9 min's per flight and 6 flight's per gallon..

That's tank's per gallon and min's per flight with Trex heli's..

For sport flying you don't need 30% nitro but at I wouldn't go lower than 20%.Reason for that is 15% is a little harder to tune and the motor run's hot with it...
Sound's like your new to the hobby so a 50 size nitro with a OS 50 Hyper is a perfect starter heli..The OS 50 Hyper is a good starter motor for someone new,easy to learn how to tune and make's more than enough power..

A 90 size nitro won't only eat you up in fuel,they have 3 needle carb's and not the easy/cheap to learn with..

BTW,
Do you have a sim or any other experience with heli's?

I plan on getting 6-7 flights on a gallon with my Trex-700. = $4/flight give or take.

15% nitro works fine for me even flying more aggressive acrobatics. 30% is easier to tune. I get about 8 minutes to a tank with 30% and about 11 minutes to a tank with 15% nitro fuel on either a 50 or a 90.

If you are new to heli. Get a 30 size.The fuel consumption is low so you get more air time. And that what counts

Just curious did you guys put smaller tanks in your 50s
I can only fill my birds on a gallon 8 times a raptor 50 v2 and titan 50 se
And to me that equals 8 flights per gallon for the 50s
I don't know ??

Thanks for the information. Yes I do have experience with helis and just wanted to go ahead and get something I'm going to keep for at least a few seasons. I just wasn't sure how much the 90s really burned.
