Default 24 oz. tank size ?

About how many minutes flying at mostly full throttle, can I get out of a 24oz tank using a Zenoah G-62 ? []

I'd say less than an ounce per minute.

I'm with thepamster, at mostly full throttle .... about 15 minutes would be my guess. Depends on prop load and other factors though. I can't think of too many planes that would fly most of the flight at full throttle though .... even a warbird has to slow down every so often.

Approximately 2.0965 oz/min at full throttle.

How the engine is tuned and atmospheric conditions will make quite a bit of difference in fuel consumption . I have a well tuned G62 turning a Xoar 23x10 prop and getting 14 min at WOT on a 24oz tank.
The engine is tuned to max RPM on Hi and L is set only rich enough to get the best transition. Others will get different results as we all have different tuning preferences and conditions .
I have always used a rule of thumb to use 24oz tanks up to 52cc engines and 32oz tanks for up to 70cc , 50oz for anything over 70cc . I like to have fuel to spare for the needed go around if the field is crowded and I dont like to get the tank near empty it is not worth the risk of running out of fuel if I have room for a proper size tank . Having said all that I feel you can use a 24 oz tank for you G62 as long as you know the limitations and use a timer during your flight .

Just a general observation....If one must fly at full throttle all the time either the power available isn't enough or the model is too heavily loaded which goes back to powerplant too small.

I almost never use full throttle for anything other than showing off, full bore OOS vertical stunts. My DLE55 model has a 500 cc tank in it and I get 15 minutes flying time per tank. Mostly 1/2-2/3 throttle work. Same as my 33cc powered model with a 330 cc tank. No need to overthink this. One guy's opinion!

MTK , The OP is seaking relative info specific to his engine and fuel tank capacity with regards to flying time at or near full throttle ,who are you to judge him as though he has inadequate equiptment .. A lot of warbird guys fly wide open the whole flight does that mean they are all doing something wrong because you don't fly that way.
