Gas conversion question?

What size glow motor is a DLE 20 close to???? does anyone have a cross chart from glow to gas CC? Link?

In terms of displacement, it's fairly simple math.<div>
</div><div>1 cubic inch = ~16.4 cc</div><div>
</div><div>So...you have a, say, OS 1.20 : </div><div>
</div><div>1.2 x 16.4 = 19.68</div><div>
</div><div>There, roughly, is your DLE 20 :)</div><div>
</div><div>You'll find some various discussion about the 2 types of motor, with one side saying one is "more powerful" than the other, etc...and, certainly, there are some differences in how each performs in given circumstances and scenarios.</div><div>
</div><div>Having said all of that, however, if you're simply looking to convert an existing airplane from one to the other, simply doing the math and getting close will suffice.  </div><div>

The DLE 20 is too big to use on a regular Pete-N-Poke

Look no further. A SuperTiger 2300 is a fine glow engine to get. Also if you later decide to go gas...Ken Lambert does a real nice conversion to gas for the SuperTiger 2300. He places needle type bearings on the rod and a Walbro pumper carb. Capt,n

Pete-n-poke was just a picture.. I am considering the gas motors for future projects... Thanks so much for the info...that makes it easy to convert!

I have a couple of 1/4 scale planes and other big planes so I am considering some gas motors..

Well, if you try gas power you will love it. And there are several engines in the 15, or at least 20cc and up range that will work great. I have several 90/120 airplanes flying gasoline engines, and love them. From there, bigger is even better...

When considering conversion to gas from glow, don't bother with ABC engines.

Stick with the ringed engines.

Oh yes. Very, very yes.

Absitively!! ;)

Seriously, the ABC engines won't work properly on gasoline.

But was the OP asking about converting glow engines to gasoline, or just wondering how the size (displacement) comparisons of glow engines to gasoline engines worked out?
