most of my planes are powered by 4stroke engines, and are cowled,and the require a electric starter, I prefer the ease and safety of a electric starter the 12V gel battery isn't heavy at all there cheap and work well .

as for fueling I have the EZ fueler and I don't mind pushing a button to fill my tank with larger fuel tanks either a electric or a crank fuel pump is the only way to go.

if your running a small tank 1/2A or a small engine then the bulb is fine after a while its just a waste of time and effort,for a 91 4stroke with a 16oz tank no way, I would spend half the day filling tanks up.

the difference in price 1$ between the electric and the manual version of pumps.
