I just got a cox 010, always wanted one as a kid, found plans now got convinced to build an airplane for our club demos.
I have no intention of building a stunt tank that small, which perfect tank will work?

Whichever tank fits 'Perfect'ly... Sorry, I cannot be of help, but I just had to.

Ok. So just after posting, I may have had an idea. I do not know if this will work, but I will suggest to try a balloon tank. But with something as small as a .010, a water balloon would probably work alright. I run them on my TD, and reedies without problems.

Here is a tank I built for the Cox .010. Externally, it is 12mm (h), 16mm (w), and 30mm (l), or something less than 5.7cc - less for interior dimensions and tubing, so the whole thing is less than 0.2 oz. (Based on 30cc - 1 oz of fuel, approximately). This give enough of a run to get four of these things started, takeoff and complete 10 laps. This is a square tank, set up as a uni-flo, with the pick-up and vent on the bottom outside portion of the tank. So, depending on what you want to do, a Perfect tank, around .2 oz will work for a run of up to 2 minutes or maybe less less.

I'd go with the three drop tank

I would go for a small balloon tank. I have had good luck with them. The only problem is you need to replace the balloon once in a while. I think it is the oil that eats them up with time. If you are not going to fly the aircraft for a length of time I would remove the balloon and discard it. It's been my experience that they turn to mush with time.
