Is there anywhere Ican find a gas to glow conversion chart? I am building the TF 1/7 P-51. The kit calls for 60- 90 2 stroke or 90-1.20 4 stroke. Being a bigger is better kinda guy Ihad planned on the 1.20 4 stroke. But Iam wondering about installing a gasser instead. Specifically, the DLE 20cc. But is that not enough? Should Iconsider the 30cc? Or is it in fact too much for that model? A gas/glow conversion chart would be helpful.

I have 1/7th scale World Models P-51 and I have DLE 20 in it. Great combo. This engine breaks the old school conversion rules. It is a bit more powerful than a Saito 1.25.

Only because the Saito 1.25 four-stroke is a dog, as far as glow four-strokes go. Still, I suspect that the DLE 20cc gas engine would be okay in this model too.

Well, it is also more powerful than my YS 1.10. Is that one a dog to? And the DLE 20 is more powerful than most 26cc engines.

Gotta love the haters!

Yes. YS engines can have problems too. Just being a YS doesn't mean that it is performing up to spec.

I own a DLE 20cc engine and it is strong, but let's get real.

Have I claimed anything in this thread that isn't true?

I just wanted to know if there is a chart or scale anywhere that gives a basic crossover from glow to gas.  Just like when you buy a kit the manufacturer will give you the option of a 40-60 2 stroke or 60 to 90 4 stroke. 
The Top Flight kit for the 1/7th P-51 calls for a 90-1.20 4 stroke.  I am guessing there is no conversion tables that show a 1.20 4 stroke glow would convert to a 20/30/50cc gas.  I wasnt concerned with brand loyalty at this point.  That all comes later.    Thanks for the input fellas.

Interesting, I wasn't aware that the 1.25 Saito was a dog power wise I thought it was quite a strong runner. I know the 120 was a dog and somewhat heavier than the currant engines they make today in simular displacement. But the YS 110 is no slouch, I have not read alot of RPM storys on the 20 DLE just that it is supposed swing a 16x8 prop at around 10 K if memory serves me right.
The DLE-20 should power that plane just fine, Although it looks like the 30 can fit in the nose of that plane I feel it would be a drastic overkill for it.
I would add up the AUW of each engine and components you wish to use, those plane's are already on the heavy side, if built fully loaded with all options. I don't recall the weight on mine at the moment. I use a 120 webra speed in it and it has more power than it will ever need. I'm considering making the Webra a gas conversion due to the rising cost of glow fuel.
At your Alt a person may not need the big boy engine to power the plane, but where I am at, I go the larger end of the recomendation sometimes more.
Spinner what YS 110 are you compairing the DLE-20 to I can maybe see the 110 FZ but the newer S series 110 is a real powerhouse of an engine for it' size.

I had a YS FZ-110S up until about two weeks ago. I sold it on Ebay. It was pretty strong and would swing an APC 16x6 in the upper 9K range or right at 10K depending on how much money I wanted to invest in high nitro content fuel. And man, did that thing drink the fuel! I currently own a Saito 1.00 and have owned a 1.25 as well. I don't get the "1.25 is a dog" comment either as I found it ti be a pretty potent engine. My Saito 1.00 is a sweetheart of an engine. I'll never sell it. I've got two DLE-20s and plan to own a few more.

Saitos are engines for old men, or young nitro-freaks using mommy and daddy's credit cards. That way they don't notice how frequently they blow up. They just buy another half dozen when they run out.

Just kidding folks. And I am an old man myself - which doesn't give anyone the right to pick on me because of it. (wink-smile)

No, I won't say you that you have said anything untruthful at all. I'm just a little surprised (and more than a little forgetful) that you hold the DLE 20 in such high esteem. That makes me feel better about the one that I have.

Just back from getting my old stents cleaned out and two new ones installed in the Iliac arteries. Soon, it will be all stents in there. Oh am I glad to be here. Truthfully, I'm glad to be anywhere!

I've had several 120 size engines and have 5 saito 125 engines. The Saito 125 is no dog compared with other 120 size engines.

The Saito 125 bolts in the same holes that the Saito 100, OS 91's, and the Y-S 91/110/115's do.

Compared with the 91 engines where the engine will fit, the Saito 125 is a real power house.

I have a You Can Do 60 with a 125 and a couple of Twist 60's with 125's

The DLE 20 compares more favorably with the Saito 150 with its 16 X 8 prop.
