Default Fuel tank sizing question



Trying to determine proper fuel tank size for a DLE35-RA. Had an 800cc tank planned but its too tight in the layout.

Will a 550cc (18.5 oz) work?This is in an RCGuys' AG Wagon. How long at normal flying speed do you think this tank will last?</p>

That tank should last about 15 minutes at WOT

That should work just fine. Fuel burn should be 1.2 oz per minute at WOT. <div>

16 oz is good enough

I've read this "rule of thumb" few time on this forum: "A gas engine with a conventional muffler burns approximately its displacement in cc's each minute at full throttle." That would seem to agree with the other replies. (550/35=15.7 min.)

What's the approximate difference between WOT and say 3/4 throttle, and would using a linear measure be a reasonable assumption.

it is load dependent, not throttle position.
True assumption: You will use less.
