  • Considering my First Gas Plane - Any Advice?

    This past Sunday at my club field, there was a large amount of folks that brought their gas warbirds. The coolest one for me was a Galloping Ghost made by CARF (I think?), powered by some Kolm engine.

    Watching a bunch of these birds in flight suddenly made me want to get a gas warbird, and I an contemplating a 15-20cc plane to wet my feet.

    Any words of advise from folks that fly both electric and gas? Recommended websites for knowledge bases and discussions?

    Some background, flying electrics for over 7 years. Primarily 70mm EDFs, FW A10, and my largest warbirds were FMS 1.4m Stuka and BF109.

    And here is the picture of the galloping ghost

    Stay electric.

      My advice is DON'T DO IT !

      Nothing good can come from it.

        Nice flight on the P-40 Sean. How are flight times on the larger 12S warbirds?

        I hope to also get into turbines later too, same advice with staying electric? lol

          Thanks!

          As you well know, until we have a major breakthrough in battery technology, fueled power systems will give us a longer flight time for the same power output.

          That being said, I was getting a safe 5 1/2 minute flight on "junk" 5000 mah batteries back then. I'm sure I could get 7 minutes with today's higher mah, better quality batteries. My P-40 was going to be my jump to big "gassers" until I figured out I could convert that airframe. Then, while my club mates were fiddling with their gassers at the field, I just plugged in and flew. Not to mention the sound you get from an electric (prop) over the constant weed eater noise from a gasser. Thus, I don't ever see myself getting into a gasser over electric...a 5 1/2 minute flight is the limit of my attention span.

          However, regarding turbines, I think they're a lot more reliable than 2-/4-stroke engines, and provide longer flight times than our electrics. Thus, I hope to be into a turbine next year myself. I don't see myself ever getting away from the convenience of electrics, and I'm not a big fan of messing with fuels, however, as the saying goes, "nothing beats a turbine".

            Yea, I really like the convenience of electric. No fiddling, just plug in and go. The smaller gas engines can definitely sound like weedwhackers, but there seem to be a few higher dollar engines that have a much sweeter sound, and are more available as engine sizes increase (though so does price!)

            I do have concerns with having to start the motors, then moving around a plane with an active turning prop to get set up for flying. Sucks that onboard starters aren't really available until you get to 60cc i think.

            Then you have the storage, would need to keep this in the garage as my workshop is in the house, so I wouldn't stink things up.

            I'm heading to my club field this weekend, so I'll be picking peoples brains since there are a fair amount of folks who fly gas warbirds.

              I bought an NGH engine and all the support items & fuel tank for the plane. I could never get the engine to run quite right it would idle fine but surge at full throttle. MRC sent me a new engine I haven't run it up yet. I ordered a new OS engine and going back to glow power on my BUSA Eindecker. I do have several electric planes that enjoy flying when I get the chance that I bought from Motion. I've been eyeing the Flightline Corsair just don't know when I'll pull the trigger on it.

                Go for it. I fly gas, nitro and electric.
                There is quite a few 30cc class gas planes out there. If you dont want to start out with gas on a warbird then go for a nice pattern or 3d plane
                You have to have patience with gas engines. They have a run in period. Its not unusual to have a bit of a sputtering mid range. You want to avoid having the on off mid range though. By that I mean your gas engine goes form idle to a high rpm and skips through much of the mid range. That is the biggest problem I see with gas engines. Once you have ran a few tanks of gas through it though you will find the mid range and power band will be smoother. Your flight times will be at the minimum double your electric. Cost wise is an age old debate. I use ethanol free, "recreation gas". Some call it marina gas because its the type gas people buy for their boats. Like nitro, with gas you will get bogged down with everyone having their own opinion of what oil to mix etc. etc. I ended up with stihl ultra synthetic oil because i can buy it anywhere and it meets all the standards.

                  Electric flight is almost hassle free. EDF jets have come a long way too. If Tesla were alive today, we'd probably be using "wireless electricity" to power the planes. Would be nice if Elon Musk could offer the RC world a line of Tesla batteries that give 20 minutes of flight time! Fuel still has it's place and I'd love to have a turbine and all that goes with it...
