Kindly help me who knows or can provide me a chart or informaton concerning fuel tank size for specific rc engine size like engine size and ounces used for time flight. Also need information if a 16 oz. tank will be fine for a Webra 120 engine. Thanks.

.049.......................................1 ounce
.09 to .15...............................2 to 4 ounces
.19 to .25...............................4 ounces
.29 to .35...............................6 to 8 ounces
.40 to .45...............................8 to 10 ounces
.60........................................12 to 16 ounces

Larger than .60, see kit manufacturers instructions

The figures are useful guidance for general use, and recommended tank would usually run corresponding sports engines for 10 to 20 mins. Adjust according to your need, e.g. high revs draws more fuel, high hp draws more fuel, and of course how long you want the flight to be.

Different engines consume fuel at different rates.
How you adjust the engine will also affect consumption.

the rate an engine consumes fuel and burn it, at reasonable efficiency %, results in its corresponding power output in hp or kW hence an indicator. It also takes care of power boosting designs like pumps, pipes and air chambers that alters intake pressure (i.e. amount of air and fuel), otherwise it's just a product of displacement and number of revs based on a certain mixture ratio like when you "prop it down".
