I did not have to own a Russian made Lata to know it was a horrible car... I do not have to own a Zenoah 2.0 to see the numbers and user reports.

Learning from other peoples mistakes, a pretty novel idea for you huh ? God, I hope you dont have kids TKG, I can see it now. "Go ahead and try drugs, anyone that has not tried them does not know what they are talking about." TKG, your reasoning in your last post sounds like that of a really intelligent guy [sm=lol.gif]

Just about everyone that posted here in favor of the G-20 has only made comments like TKG above, but have not quoted ANY facts as to why this engine is not the dog that it is. Real bright group of people that have posted in this thread.

The only one that has posted anything good here is RCIGN1, his modified engine will be a great motor and do everything that the Zenoah 2.0 was supposed to do, WHEN it is available, but that is a DIFFERENT engine than we are talking about here.

What I we are talking about here is the Zenoah 2.0 that they sell everywhere. With the 3300 MAH battery pack that is needed to make it fly just 3 flights, the ignition and other accessories, makes it a heavy, underpowerd, DOG of an engine.

If you go by JETTPIOLT's way of thinking
G26 spins a 16x8 prop at 8900 rpm ,weight =59 oz no muffler $299.99
G38 spins a 18x10 prop at 7300 rpm ,weight =79 oz no muffler $299.99
Any one who would buy a G26 instead of a G38 for the same money = STUPID

You did not read the thread Bart. You are so anxious to jump in here you post some stupid comparison that has NOTHING to do with the issue at hand. The G-26 is lighter than the G-38 and does not have a 3 flight limit, your comparison is misleading and FALSE.

Im talking about the Zenoah 2.0 having LESS power than the G-26, for the SAME weight with some pretty horrible limitations.

The Zenoah 2.0 has LESS power than the G-26, and when you consider the 3300 MAH battery that is required to run the Zenoah 2.0 for 3 flights, it is the same weight.

693Bart, You obviously have a hard time keeping track of a just a couple importnat facts here, but that goes right in line with what I said about anyone that would buy a Zenoah 2.0 not being the brightest person on the planet [sm=lol.gif] . Your post is right in line with the rest here, you have no facts to support what you are trying to say. The best you or the last few Zehoah 2.0 defenders can do is post something false, or misleading, or just plain dumb.

How come people are always comparing Zenoah engines with magnet ignition to other engines with EI ? Of course a mag engine is heavier...
READ my post, the G20 is about 11 oz lighter than the G26 when both have EI....
rcign1, proud member of the STUPID club
I have a G62 here with EI that weighs 3 lbs, 14 oz WITH ignition and a battery...I guess that makes me double stupid...So be it....
Or false (show me where)

I read your post very carefully, and went over your numbers. Your post was the ONLY one in this bunch that was in any way intelligent.

But did you read my post ? I was VERY CLEAR that I was talking about a stock Zenoah 2.0 that you can buy anywhere. Any engine can be modified to accomplish just about anything, but that is a different discussion... So lets keep it to what people can buy and install in your plane right now. With a STOCK Zenoah 2.0, you need 3300 MAH of batteries to get 3 flights, which really is not acceptable... Most people fly more than 3 times.

STOCK Zenoah 2.0 with a 3300 MAH battery = Same weight as the Zenoah G-26.

If you think this is wrong, im all ears.

I am disengaging from this thread. Jett you need not tell anyone how they should act, calling practically everyone that has a G20 stupid. You don't seem to understand that people don't care if the engine is Heavy as you say, they just like the little engine. I seem to be in the majority in my opinion about you so I'll just take it at that.

Well, next time I'm out flying, hovering around with my G20 powered Laser, using less than 6oz of gas for a 12 min flight, I'll have to just keep telling myself how stupid I am.
PS APC 17x6 @ 8700 rpm, PPS 10 lbs of thrust works just fine in a 7lb plane
Oh by the way its Lada, you can't blame the Russians for it, its a Fiat 124.

You never did respond to what the weight of a STOCK Zenoah 2.0 would be with a 3300 MAH battery. You seem to have avoided this question for days now... I expected more from you Ralph than for you to take whatever side of an issue you perceived to be "popular". You of all people know what the weight of the Stock Setup would be. I gave you credit for being smart and honest in your posts, it looks like I was wrong.

Are you afraid that a real answer to my question might prove me right ?

If your running a stock G-20 you dont need a 3300mah battery. A 1000 mah will do just fine, after all thats why they make field chargers.
Each to his own you fly your G26 and have fun and I'll fly my G-20 and the other Z engines and have fun too.

Jett seems to be hung up on the 3300mah battery, short flight time and thrust.

I have a G-23 that has run trouble free for four years so I understand that part of the argument. However Tony Clark's web site suggests using a 2450mah single lipo for approximately 1 to 1-1/2 hours of run time. Total RTF weight is 43 oz including all components and battery. That being said a stock mag G-26 weighs 59 oz, exactly one pound more, too heavy for intended use in most .60 - .90 size airframes.

The G-20 at $339.00 makes it a bit pricey but is on par with other EI gassers of this displacement (BME ST 90 and FPE 1.3). Sure there are others (MVVS, etc.) but parts and service don't come close to these three.

Obviously one can save almost another pound with Ralph's conversion but adding the conversion pushes total cost to approximately $450.00. Also changing the ignition to C&H adds cost and battery conservation but little or no weight savings. Of course my stupid thinking says, for my money, the G-20 would be fine using the Tony Clark version.

Manufacturer's thrust numbers are either conservative or out to lunch. Using Horizon's specs the 10 pound thrust for the G-20 is more than adequate for 8-12 pound planes and it doesn't need heavy batteries to operate. Base on my G-23's annual performance gains, I think the G-20 will produce more than 10 pounds once broken in plus prop trials.

Not every engine has to be a 3D capable featherweight to provide good performance. Buy and fly what you like or want, it's your money.

I'm not planning to do any mods to anyone else's stock G20..I bought one for myself to use in my Phaeton 90 bipe...I didn't weigh it before changing the hub and stud, anyone can go to the Horizon website and look it up..I posted the weight of mine as a point of interest, anyone can duplicate it....I changed the hub and sensor mount on the front of the case and to make the engine a little shorter...I didn't like the stock carb mount so I made a thinner one from G10 like my other conversions...Having heard about the stock heavy and power hungry ignition I got one from TKG...There is nothing done to the engine that anyone with a sander couldn't do...
My problem with you and most others on here is comparing stock magneto Zenoah engines to other brands with EI....
Does the stock G20 weigh the same as the stock G26 with mag ignition ? Probably...Is it made to take the place of the G26 ? Nope, look at the comparison picture in an earlier post...Am I selling conversions for the G20 ? Nope...Did I ever say I was going to ? Nope, Am not..
No use trying to reinvent the wheel, the G20 is fine just as it comes from the box..I haven't tested the ignition, don't plan to use it...Anyone wants the igniton, hub, stud, and stock sensor can have it for postage, I'm going to cut the shielded lead off to use with something else.,.
Mine will have a C&H....
There is nothing to "convert" to use a C&H ignition, it will work with the stock sensor...
The C&H ignition I have here weighs 3 or 4 ounces, a battery to run it for at least 2 hours weighs 2 oz, costs $13....
FWIW, mine turns a Mejzlik 18-6 at 7900 rpm, the thrust is probably closer to 13 if you have the ground clearance...Pretty good for a dog that weighs less than 2 lbs....

Tony Clarks website is wrong. People that have bought the Zenoah 2.0 have reported the ignition battery going dead after just two flights. THe ignition battery does NOT last as long as the website claims, immagine that The ignition has NO protection for a LIPO battery, so if you run it down its gone, not good.

This is a typical story...

"" I've have had at least 20 dead stick landings in a Funtana 90. I stopped all the dead sticks by making sure the 2700 mah batteries are fully charged every two flights "

Zenoah 20 Engine weght 41.6 ounces + 2200 mAH battery+ Foam for battery, ignition etc. = 50 ounces total

Zenoah G-26 = 59 ounces total

So lets look the finished product. The Zenoah20 For 50 ounces you get an engine with 10 pounds thrust that you will have to field charge every other flight... Why mess with gas at all, it might as well be electric [:'(]

With the Zenoah G26 might be 9 ounces heavier in the end, gives you 17 pounds of thrust, and will fly all day with no batteries to charge.

Its so simple even a caveman could figure it out

Stock with a 2500 ma battery and muffler and ignition is 44 0z, you must have some really heavy foam.....A C&H ignition module is about 1 oz lighter...

I was computing the weight using a NIMH Battery, I would not use a LIPO on a non cutoff circuit, especially one that drians it as fast as the Zenoah 20. LIPOS are expensive, fragile, and you will be buying a LOT of them if you use it on the stock ignition [:@]. But if you must use a LIPO then here is one using your weights that is even better.

Stock Zenoah 20 = 44 ounces total and 10 pounds of thrust.

RCIGN Zenoah G26 = 46 ounces total and 17 pounds of thrust and flys a LOT longer.

Its so simple, even a caveman would use the better, more powerful engine being that they are the same weight

JettPilot says that Tony Clarks website is wrong. Anybody out there has tested this engine with a single LIPO battery? How long does it last?

In Tony Clarks website says that the consumption is of 1.6 Amps at full throtle. That would give a very safe hour of flying out of a very light 2000mAH LIPO.

JettPilot

My Feedback: (6)

Lets take your assumption that Tony Clarks website is correct, given the BEST CASE lightest setup for the Zenoah G 20 you weight is still 44 ounces, and you are limited to one hour of flying [:'(]

Stock Zenoah 20 = 44 ounces total and 10 pounds of thrust.

RCIGN Zenoah G26 = 46 ounces total and 17 pounds of thrust and flys a LOT longer.

Now who would want the Zenoah G-20 that has a severe running time limitation, when the RCIGN Zenoah G-26 puts out 70% MORE thrust, runs longer, for basically the same weight ? Anyone have an intelligent answer based on facts to this one ?

Thank you Joan C. You pointed out that simple math provides the answer.

1.6 amp drain is pretty light work for a 2450 Lipo even if it is only 8C. Some folks reporting dead nicads/nimh after two flights may be using batteries not up to the task of high, continous drain. Not all nicads/nimh can handle hi current drain no matter the mah rating.

Also Tony Clark has probably tested this combination throughly prior to selling it. I'll take his word above most others.
