most all 50cc aerobats will come out in the 15.5 to 17 lb range
most lightweight 50's da,bme zdz will come in at around 4 pounds with ignitions, batt, muffler and that is plenty of power for up to 17 lbs
most would only use 1 RX batt on a 50 cc size probably 2200-2700 ma depending on servo choice
you would also need a 4.8v ignition batt around 1600 ma NIMH works great for both
You will need gas safe fuel tubing and a gas stopper for your tank, also soldering barbs on the fuel pickup tu8bes is a good idea because gas mix tends to be a little slippier and lines can come off
If your looking to put a 80cc in a 50cc size bird you are probably looking for vibration problems
You need to keep everything ignition related seperated by anything Rx related seperated by 6-8" or more
Finally, buy good quality lightweight stuff of any good brand and dont sweat a few ounces difference. It wont make much difference in a bird that size
