Zenoah G20 or DLE20
I am aware of the differences in weight (approx 11oz.) and the other pros/cons of each engine. I am looking for input from others as to what your choice would be. I am looking to get a 20cc gasser to replace the 4strk 1.00-1.25 kits/planes that I have and can't seem to make up my mind. I like the small footprint of the DLE but I am drawn to the long history of the Zenoah line up. Having several Zenoahs allready, I know how nicely they are constructed and the quality that is there not to mention the reliability/longevity. My experience with DL (while running good, the quality wasn't there and I had to helicoil the spark plug threads due to soft aluminum that gave out). The casting was terrible as well. Don't get me wrong, I am not bashing just stating what I observed in my personal experience. So.... does one go for the larger footprint, slightly heavier engine that has a solid history and excellent craftmenship or the yet to be released, smaller, lighter and no history engine based on what has held true with the 30cc version? Decisions, decisions!

RE: Zenoah G20 or DLE20
Ive never owned a Zenoah and im not going to bash them. I know several guys that have them a they run like a top. Im on my third dle engine, I bought a dl-50 and put that on a 50cc Extra 260 and the engine was a monster, not a single problem with it. I bought a dle-55 and put that on a 35cc Extra 260 and not a single problem with it either. I just bought a dle-30 and mounted that on a taylorcraft and its a little monster for its size. Im hooked on dle engines. After christmas im going to order another dle-30 for the 30cc Aeroworks Edge 540 thats coming out. I think for the price they are some awesome engines and they seem to be holding up really well. You know in the past ive read threads with people bashing dle's and talking about there bad experience with them, then I got to thinking, you never know what that person has done with that engine and what they have put it through. So you cant believe everything you hear. Personally I wouldnt be affraid to buy another one, they have proven there self to me.

RE: Zenoah G20 or DLE20
I have a DLE 30 & 55. They start & run great! I have no problems with them at all. They are quiet powerful! I know the owner & emplyees of Aeroworks pretty well. They are members of our club, and they are located down the street from where I work. So, I drop in from time to time to say Hi and look around. I was told by one of the employees I know well: "He has never seen them come back so excited from a test flight"!. They put one of the new DLE20's in a smaller (120) version of one of their Extra's.... They were very impressed. Now please keep in mind that I am NOT speaking for Aeroworks, only what I heard.

RE: Zenoah G20 or DLE20
antique is dead right! Be sure to read this very detailed manual on the G20 engine. You can also apply some of this good advise to a lot of engines....you know the how to things for best results!
I think I will try the 3...not ...4 cell Nicad battery pack. Read & you will see why. Capt,n<hr />http://www.toni-clark.com/ftp/ZG20_en.pdf

Ralph,
Is this what you are talking about on the G-20 ignition?

Original: Toni Clark
For the first time Komatsu Zenoah is using a high performance micro processor battery ignition with automatic timing advancement, specially developed for this engine. This ignition unit is unusually powerful and this makes for very easy hand starting. The high tension cable is well screened with a metal plug cap. We fit the ignition module with a CNC-milled base for protecting the wires and to provide an easy installation in the model.
The current consumption of the Zenoah ignition unit is certainly a lot more than is so with other model aircraft ignition units, but the Zenoah unit runs perfectly with a single cell Lipo. Energy consumption is exactly the same, whether a ignition unit is run with 2 Lipo cells at 0,8A or the Zenoah ignition is run on a single cell with 1,6A. With the Zenoah ignition there is a big difference compared to the usual "model engine" ignitions, the professional Zenoah construction team decided on a hotter spark rather than a unit with the lowest possible current drain. In the Lipo era Zenoah's path is without doubt the better option. The Zenoah unit is so powerful it can give a spark that easily jumps 4 cm, this explains the superb ease of starting and running characteristics of the Titan ZG20.

Zenoah Ignition current consumption
| Ignition current consumption at: | 3,7V Lipo | 4,8V NiMh |
| At tickover 2000 U/min | 1,1A | 1,4A |
| Above 4,500 RPM up to max. revs | 1,6A | 2,2A |
| With engine still | 45mA | 55mA |

For the size of battery & current draw.....see page #7. For you guys that want to lear more...read all 22 pages. lots of good solid advice.<hr />http://www.toni-clark.com/ftp/ZG20_en.pdf<hr />Capt,n

RE: Zenoah G20 or DLE20
Ok, so read the bit on his site and that has me leaning even more towards the tried and true little G20!! From what I gather, one should either use a single cell lipo or a 3cell NiMH/Nicad pack to lower the consumption rate and make it more reasonable as a 4th cell is not needed on aircraft use. I just wonder if my Triton II will charge just a single lipo cell???
Any other insight users would like to give?

RE: Zenoah G20 or DLE20
Note also in Toni Clarks manual that he does NOT recommend the CM6 spark plug, saying that although it looks the same as the supplied Champion, they are NOT the same. Anyone know the difference? Thanks.

RE: Zenoah G20 or DLE20
Measured reach on BOTH Denso and CM6 is .405-.430..without the washer, from the flat face of the plug thread to the end of the side electrode..Measured with a digital caliper with .001 resolution...Don't believe all you read on the spark plug website...As to the Y82, don't have one here, but 1/4 inch reach would leave about 3 threads left after the gasket was put on, hardly enough to keep it in the head....

Thank you. I just got a new flyer from HF today and the 18 volt battery pack is $9.99. Plus, I have a 20% off coupon so that will make the pack $8.00 plus tax!!! WOW! I think the 20% coupon is availabe on line; I got mine from the Sunday paper.
Thanks again Captinjohn.

I mean spaceworm, the pack I bought was for a electric drill. I do not know what the lantern pack has inside. Drills take a pretty good pack to run but a lantern may just sip electrons. You may want to check before you buy. Capt,n
