32 parts gasoline and 1 part oil. That is less oil than 30 parts gasoline and one part oil.

Since I'm one of the own of DLE20 and I would be experiencing my engine may be the end of January 2012, or February. There is another thread of Chinese gas engines, and it looks like we are under an influx of Chinese engines, which is good in a way that price may get plummeted but so far, it's seems like a shot in the dark.

http://www.rcuniverse.com/forum/m_10316994/anchors_10486267/mpage_16/key_/anchor/tm.htm#10486267

DLE20's been spoken a lot about and spoken high. I would like to ask a simple question of those who had been, or had used the DLE 20 engines in the past. The question is

What is a life span of DLE20 or bigger size gasser, how long do they last if not abused, and what are the precautions to be taken in order to keep it running good.

I know nothing can be predicted precisely when it comes to any electronics or mechanical stuff, but experiences make us learn the ropes.

Thanks y'all, happy flying and happy holidays

Mody

Here is what I'm doing to keep my DLE-20 happy (which means I'm happy since I own two)
Correct fuel to Oil ratio with a high quality synthetic oil
Correct mixture: (Not too lean - Not too rich: either will cause problems)
Don't over-rev nor over-prop
(Don't crash)

Plenty of information on each of these on this thread.

Good engine.


Paul

Great information. I bought me a wooden prop 16X6, and I might get 17X6 as well, don't want much speed but thrust. One thing I would like to clear it up, for the fuel, I bought Klotz 32:1 synthetic oil

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXS626&P=ML

and I have to buy the Hi Octane Supreme gasoline, that's it or something else?

How much would 2 gallons of VP fuel cost, that is what I mix up at one time. I have heard good things about it but is it cost effective if you fly a lot of gas.
Thanks

Status: offline 		I'm using no-ethanol Rec fuel now but I started with 87 Octane pump gas and it worked just fine. Other than the possibility of some fuel line being more reactive to the ethanol than others, I believe that the uber-experts support the use of plain, out of the pump non-premium gas.

Everything else being equal, I don't believe that the gasoline will have any substantial effect on the longevity the engine.

Some have found a brand or type of fuel that works better for them. I use ethanol-free because I can get it and I'm not sold on the whole ethanol thing in the first place and it works fine for me.

What brand of fuel is it that has "no-ethanol in it, I would like to start using it if it is available where I live.

I mis- read or mis-understood I thought you where talking about pump gas with the no-ethanol Doesn't someone have pump gas with out the ethanol in it ? I myself can't see paying $70.00 for 5 gallon of airplane fuel as much as I can go through, I just can't see how it is that much better but maybe someone can enlighten me.

I thought the whole point of going gas was to cut down on the costs of flying with Glow. $14 a gallon for gas is crazy.  Heck $4 a gallon is crazy.

3 Ready-To-Use Versions
  • 4 Cycle Unleaded Gasoline
  • 2 Cycle Premixed with Oil (50:1)
  • 2 Cycle Premixed with Oil (40:1)

Each available in quart containers, 5-gl pails, 30-gl and 54-gl drums

I don't know the brand of the stuff I use. I am told that it is only legal for use off road or in motorcycles and antique cars - at least in Florida. I get it from a performance motorcycle/marine shop in the Orlando area. They also sell VP.

The good news is that this non-ethanol REC fuel doesn't cost too much more than premium at the pump.

You might check out marinas in your area. They usually carry no-ethanol gasoline. Just remember that with the compression ratios we are running you don't need high octane,

Paul

We gat a lot of off-roaders here on weekends and holidays and they are the primary customers so it kinda makes sense. I've been looking at going to gas from glow, would this be a viable fuel? I'd be looking at smaller displacements, 20cc and less.

The thing that the guys around here joke about is how little fuel my DLE-20 uses.  I had a dead stick and was saying that I don't understand, I put gas in it last month.  It will go 4-5 flights on one (1/2 liter FiJi bottle) tank of gas, and of course, there is no slime on the plane, no starter, no glow igniter.  It is: ignition on, choke on, flip 3-4 times until it runs and dies, then choke off, flip it and it is running.  Usually after that, it is a single flip the rest of the day.

With this Klotz synthetic oil+Gasoline from the gas station is all I need for my DLE20.

I will appreciate if anyone can answer me on my question since I'm gonna use DLE20.

Thanks

All that's required for our gas is regular, and 10% methanol is fine for any of our toys of the past 15 years or so.

Think of the gas your weed trimmer, chain saw, edger uses....regular gas + 2-stroke oil at the correct mix ratio,
nothing special - same for most of our RC gassers UNLESS the mfg specifies otherwise (the DA60 requires premium for example).

My limited understanding is that this is due to these newer engines using gaskets and membranes that are compatible with alcohol (ethanol in the case of gasoline).

Regular Gas seems to be fine idea

What about the Ethanol? is it lower graded than regular one and is it available at the gas stations?
