Tank 2 ounce
1oz for speed runs.

I fly my NV .074 in Herr Cloud Ranger using a 2oz tank. I've flown an unrestrained 22 minutes before dead sticking as I taxied back to the pitts.

1oz will be fine for 9 mins plus a little for "just in case".

2oz is ample.

Yes depends if you are swinging a big prop the rpm is down and the fuel draw is down.
If you prop for 25k unloaded you wont get 9mins on 1oz.

These are the really nice 1oz tanks Amp Abuser pointed me to: LINK
They're an extra buck or two from other models but look at the clunk - it is designed to meet the tank at the best angle to get most of the fuel. Nice stopper arrangement, kind of a positive lock.
Recommend, and thanks AA.

Yes they are the best 1oz tanks you could hope for snags every drop of fuel
per the clunk comment. Quality stainless steel lines zero leak issues.

1oz is a little bit small, unless you really like to fly short times and always land dead-stick.

2oz is much more useful, you don't have to fill it completely if you want, or you can simply cut the engine off with the throttle if you want to land and don't have a landing gear. I don't like the big rubber stoppers on the common tanks, it is just adding weight. Thunder Tiger have (or had) some really nice ones at 2.5oz with just a small, lightweight, o-ring seal in the front. The idea is the same as on the Hayes tanks (these are also gone by now perhaps...?).

Registered User Norvel posts their fuel consumption in their specs. I think I just copied and pasted this from another forum.

header tanks for RC helicopters are usually 2 oz and high quality. I'm using one on my .074 powered Stryker. They are a little narrow, but so far it hasn't show to be a problem.
