I have always been a fan of large 4 stroke nitro burning engines unti I got my first gasser which is a crrc GF26I. I was always under the opinion that these gas engines were too big, hard to start, and vibrated everything loose. Was I wrong. This little 26 takes the place of large 4 strokes, is easy to start, runs like a swiss clock, easy to start, weighs 2.5 lbs , pulls a 13 lb warbird around with no effort, sounds great in the air, cheaper to buy (just over 200.00 ) So why do we need nitro burning engines. The distributor for these engines (rconlysite.com) tells me that a lot of people are switching to these gassers and I can see why. Just my thoughts

Status: offline 		Yep. And bigger gassers are "better", and there ain't NO doubt about it.
I said bye bye to glow some time back, and haven't doubted that it was the right thing for me.

PROs

Lower operational cost.
Less mess.
No slime.
More "real".
Lots less "field equipment"

CONs

Smells bad.
Technically more complex.
Needs ignition batteries (if EI engine).
Can be really noisy.
Can create radio issues if "not right".

Status: online 		there is a certain break-even point between glow and gas. That is at about 25cc. There are good 25cc+ gassers, and there still are some glow engines that perform well. Some manufacturers even spent years of hard work to make large glow engines work well (like OS).
Advantages? No, not realy. For a 26cc engine I personally would use a gas engine, and not glow, though I have the MVVS glow on the shelf. For 23cc, my ST2300 glow engine is a champ, but I would rather have electronic ignition on it, were it not, that methanol conducts current. So a little bit too much fuel will flood out the spark.
For power, methanol is the best, but at the expense of lots of fuel, and only a few quality oils will mix with it. These quality oils never obtained the quality levels that gas oils did. So for engine longevity and user friendliness, gas reigns above 26cc.
(example: don't try to start your big glow using the normal flip. You need to bump start it, or risk your fingers)
This uncontrolled moment of fuel ignition is exactly the reason to go to gas in larger engines.
Gas engines have smoother power and lower vibration levels than glow engines of equal capacity. Once run in, less slime to wipe off, and yes, A long learning curve before you and your gas engine get along. A gas engine is no easy push-over.

Status: offline 		By the grace of A123 we now have a third option in the 25 to 50cc size range at a reasonable price.
Just think - no fingers in the prop, no starter,glow igniter or ignition battery to charge. No fluids to fool with and NO NOISE to get your flying field closed.
And then the only thing to wipe off your airplane is dust.

I flew large electrics for a while and enjoyed for a while, Set up a couple large planes, 80" Extra and 96" Rearwind Speeder.

Even with the A123 there still is a heavy cost to set them up, With some of the good lower cost Gas engines out there now you can set up a 30% plane power system for about what you would pay for one set of batteries.

Electrics are motors, but by no means engines.
Motors drive a prop, but that's about all they do. They have no heart.

Status: online 		Can you imagine going out to the Reno races to watch the Unlimited class runs with all the heavy WWII iron flying by...silently I didn't think so. Airplanes have always made noise that sounded like either a reciprocating engine or a turbine. No reason to remove that luster now. I don't like taking long extension cords to the flying field as well.

I was in a Portland , OR area hobby shop about a week ago when the owner made the announcement that glow fuel was being immediately placed on a day by day price structure. Seems glow fuel is now as volatile as gasoline where prices are concerned. I still glad a $4.00 gallon of gas will go a lot farther than an $18.00+ gallon of glow fuel.

Yes and with A123's all you need is one set of batteries. The cost is about the same. Then the cost to recharge is almost zip.
As I said there is a third option.
I still have two glow engines and three large gas engines.
I find that I am flying mostly electrics now as I don't even get my hands dirty.
I have an 80" Extra that was designed for a ZDZ40 and a 5yr old 62" Lazy Ace that was converted from glow. Both now electric.

Status: offline 		Joe - good to find out what's wrong with you..... been smellin' too much gas exhaust for too long???

I heard that running gassers makes you fly longer..... so does that mean gassers stay up longer?
