Gas vs. electric RC flying.

Which power type wins in the gas vs. electric rc flying battle?

There are, of course, pros and cons to each and hopefully this page might help you decide which type of powered rc airplane to choose, if you're stuck in the "can't decide" category. By the way, we're loosely using the term 'gas' to cover the primary IC (internal combustion) types i.e. glow plug and petrol.

Flying rc airplanes (and helicopters) has exploded in popularity since the mid 1990s and the hobby has been one of the fastest growing hobbies in recent years. This has largely been due to electric rc airplanes and helicopters becoming so widely available, more affordable and easier to fly than ever before which is a great result of the ongoing global electronic revolution.

Modern radio control products like brushless motors and lithium polymer battery packs have turned the electric side of the hobby around, to the point where top-end brushless/Li-Po powered rc aircraft can match a gas powered equivalent for performance and duration. That was unthinkable not that long ago!

Traditionally at rc flying club fields you would have seen a larger number of gas rc airplanes and very few - if any - electric ones. But these days, go to an rc flying club and the mix of gas and electric planes might be 50/50, or maybe even more electric than gas.

Of course, gas rc flying continues to be enjoyed by many modellers and always will be, but there is a rapidly growing percentage of flyers that have moved over to electric flight, or at least flying electric planes and helicopters alongside their gas ones.

And, importantly, some major manufacturers of glow plug engines (the mighty OS, for example) have started producing quality electric brushless motors and electronic speed controllers, so that says a lot about how far EP has come!

Gas vs. electric RC flying - pros, cons & my thoughts.

As with everything, there are two sides to consider in the gas vs. electric rc flying argument.
Below is a little comparison chart showing some fundamental points to consider when trying to decide between gas and electric powered rc aircraft.

POINTGASELECTRICCOMMENTS
Price to buyGenerally speaking more expensive for the beginnerCan be lots cheaper because simpler planes are available, but high-end electric setups can be costlyYou can definitely get started for less with electric
AvailabilityFrom model/hobby shopsFrom hobby & many toy shopsGas models are more specialised, simpler electric ones can be bought from a wider variety of places
Additional / ongoing costsGenerally higher; fuel and possible club membership necessaryLess although large Li-Po motor packs can be priceyHigher maintenance levels for gas planes usually mean higher ongoing costs.
Learning curveSteeper for a 4 channel plane, which IC ones tend to beLess steep with a smaller 2 or 3 channel EP planeThe less channels, the easier self-teaching is. RC flight sims help greatly for all power types.
Environmental
issues
Noisy & oilyQuiet & cleanYou won't disturb many folks with electric flying
Club membershipAlmost essential unless you have good access to private or waste landNot as essentialMore electric planes can be flown in public places. Gas planes do carry a higher 'nuisance factor' because of the noise)
AccessoriesEssential field items needed to start and run the engineVery few needed but spare battery packs are a good ideaGas planes require more because of the engine, but at a club you can always borrow these to begin with
MaintenanceModerateVery littleThe engine makes gas planes require more ongoing maintenance, but you'll get to learn more!
RepairabilityModerate to complexMore straightforward if it's a foam planeDepends on the construction of and damage to the plane, but foam is easier to repair than balsa/ply
Flight timesDepends on size of fuel tankDepends on capacity of battery packGenerally speaking gas planes can fly for longer, but there's not much in it these days
Fun factorHigh!High!Same amount of fun can be had with each!

So there are some of my thoughts in the gas vs. electric rc flying battle. As always these are only my personal thoughts on the topic and shouldn't be taken as black and white. Also, there are always going to be very different situations and exceptions to the rules, depending on the size and style etc. of a particular plane, but the above guidelines are a fairly accurate generalisation.

Hopefully the above points can help you choose which type of powered rc aircraft to go for... gas or electric.

To round off, my bottom line thoughts are these:
