Hi everyone just joing rcuniverse and this is probably my first post...I fly a 40 size seagull on a .46 OS engine. Can i move to a 26 cc gas engine or should i progress to a bigger glow engine.
Cheers

Ummm.. that's quite a large engine for that plane. I would move up to something quite a bit larger for that size engine. I don't think the two engines are at all compatible with each other as far as putting them on a plane that size.

With that said, what is your experience level? Most gassers require some higher level skills to both build and fly. They are not as simple in the assembly/build process as the glow engine models are.

CGr.

If you can afford a bigger model then there is no reason to avoid it. Bigger planes usually fly better than smaller ones and are easy to track. Tuning a gas engine is quite different than a glow engine and mishaps are costly. There is a great big plane called Telemaster which can be powered with a gas engine and I consider it a good first gas plane, it also does fly like a trainer and does mild aerobatic maneuvers. Be aware that Gas Fuel is very different to handle than glow fuel, so too much care should be taking. As I mentioned, is also a big difference on tuning a gas engine than a glow engine, but once that you learn it, you will find it easier to handle than a glow engine.
Good luck!!

And what is the difference in tuning A gas instead of A glow???

Tuning the idle before the HSNV first.
Here is something very interesting to read:

That's it???

Heck no. The entire tuning process is different. Setup is much different as well. A list of differences is too lengthy delve deeply into on this thread.

There is also a choke to worry about that is lacking on a glow engine, as well as a airframe-mounted or transmitter activated kill switch (especially if you wish to fly at certain clubs or at IMAA events). You have to ground out a gas engine to kill the ignition if it is magneto sparked. Or switch off the battery on electronic ignition.

FLying is no different - in fact larger models are easier to see and handle wind better in general. But remember you are now dealing with an explosive and MUCH more flammable fuel. You should have all your basics down cold before taking on gasoline fueled; unless you have a good mentor who will work you through the learning process.

Another thing to consider is that large models, while easy to fly, are much less forgiving of bad landings. Bounced landings that only mean bending the landing gear straight again on a .40 size plane can mean the end of your flying day with a big bird.

The good news, you can really grease in the landing.
The bad news, you better grease in the landing.

We had one lady come to the field with a 1/4 scale Extra 300S with a DA 50. She flew it twice and on the second landing, came in just a little short of the runway and nosed over. She was done flying for the day because her $30 wooden prop was cracked. I think I will stick to my 40 and 60 size planes for now, cause it would get mighty expensive if props cost $30 instead of $3.50.

Hi. Gas engines are much heavier than Glo. I wouldn't consider a gas till the plane requires at least a 220 2C, or 4C.

A 2.20 glow engine will cost you out the nose to fuel......
I would go gas with anything over 23 CC (150 ish), but thats my opinion....
Of course, the big glows crank out an insane amount of power....
