Ihave an Epic Jet (from nitroplanes)and as per description, I need a 1.20 size engine for this plane. I am planning to put in a gass engine but I am confused what to do or which engine is lesser weight and best for this plane. Please suggest that what should Ido?

magicwar,

That is like asking someone which is better, Chevy or Ford. Best thing to do would be to research some of the engines and see how they are holding up for everyone. Personally, I like Zenoah engines as they have been around for ever and have proven themself to be reliable. Thats just my personal preference.

from the specs and weight the DLE30 will be great choice.

About Zenoah 20cc, some one told me that the problem is with the ignation as it consumes a lot of battery that is the only concern.

Zenoah 20
Zenoah 26
Aerovate 20
Aerovate 28
DLE 30
Syssa 30

There are others these are just the ones that I have watched.

Just do some reading there is allot of info ou there. Every one likes all these but for there own reasons. I'm trying not to be Bias .... In another thread I have read that the Zenoah ignition works better on a 3 cell nicd or nimh or a single cell Lipo , then the ignition does not get warm.

I'm with Zippi on recommending the Zenoah G-26. Especially if the engine has been to Ralph Cunningham for conversion to electronic ignition and a good lightning session on his mill. I've sold off a lot of my engines and ARFs over the last few years and I've bought my share of Chinese engines, but I have not and will not sell off my Zenoah G26 Lite as customized by Ralph Cunningham at RC Ignitions. That would be shear insanity.

+1 on the Zenoah G26 "Ralph Special". I haven't owned an MLD but I have seen one flying in a Cermark Extra 260 and thought the MLD-28 is pretty darn stought. (It pulled that Extra out of a hover with authority.) I do have the MVVS/EVO 26GT2 and for a 26 it's both light and strong. It turns the same prop as my Zenoah about 1 to 200 more rpms. Where it really shines is with a tuned pipe. That turns it into a real beast. In the end though no one beats Zenoah for durability, + they're right there on power and with a good diet to trim the weight they are a good contender.

I'm actually partial to the Aerovate line YD-A 28cc and the Syssa SAP-180. The thing is most of these engines are very close in weight and more cc usually = more power.

I had checked the details . I dont want to compromise on quality because this engine will be my very first gass engine.  I am just thinking about the weight of the engines. I am looking for the engine that should be best for the plane as most of the engines are having more than 1 kg weight. Here is the link of the plane. Kindly suggest me what to do? ahhh still confused . . wat to do . .. ?

the plane is

I am thinking to have a 20cc engine for the plane. . . can any one tell that which 20cc engine is lesser in weight and well performance and durable of Zenoah and RCGF. Please suggest

Either of those two engines will power your plane satisfactorily, however with the RCGF 20 being a rear carbed engine it has a much narrower footprint than the G20 and with your model having a somewhat narrow cowl the RCGF 20 might make a much nicer install.

I have no first hand experience with the RCGF 20 other than reading good reports about it's performance from its users, but I can say without reservation that the little G20 is a really big punch in a small package.
Karol

Karol - What do you think, will Syssa 180 (SAP 30cc) will be fit in this cowl (epic Jet)?. Have you any experience of that engine?  How it flys?

well "best" , that will be the MVVS 26,, for sure !!

Jim

The Syssa 180 will for sure fit inside your cowl and having both a rear mounted carb and muffler will certaintly enhance the install. The Syssa engine is in essence a new kid on the block but initial hands on reports indicate that is an excellent design and a very high quality engine, which from all indications should prove to be an outstanding product.
Karol

I have a Chinese SV-26 that doesn't equal the power of a good 1.20 glow engine, and then I have a Zenoah G-26 that exceeds the power of any 1.20 glow engine.

I'm not sure about the power of a G-20 equaling a glow 1.20 ? ? ? []

I have flown this airplane with an OS 120 (2s), it fly beautiful. this engine fly it like a missile, it could every easily be flown with a 90 size engine, I'm not so sure if the structure could handle a gas engine, but if so, i wouldn't put more then RCGF 20 or so, It is a scale airplane.
(SV-26 is very heavy, i have one)

I see the SAITO 20cc wasn't even mentioned! Interesting.

Too many users are having major problems getting this engine to run as it should and neither Horizon Hobbies or the manufacturer seem willing to acknowledge that it needs some more development work.

Karol

This plane is low on wing area for it's weight. This isn't necessarily a bad thing pending how you want to fly it. If you want to land it slowly, I would be careful about adding any unnecessary weight for the already suffering wing area to handle. If you are looking for a screamer, and if you keep it around 10lbs, I'd get a 20 that is happy running very high rpm's all day long, and have fun with it. Zenoah's are known for being happiest spinning higher than 'normal' RPM, but I am sure the Syssa, RCGF, DLE or others may do just as well for your desired flight characteristics.

Here is the Epic plane with a Zenoah 20cc engine. Check the mentioned link. I am thinking of building the plane with SAP 180 (Syssa 30cc) because the engine is lesser in weight than Zenoah and I will get more power secondly the 30cc engine can be used in some giant scale plane as well. If you have some suggestion or criticism, please suggest.

here is the beauty

From time to time lots of us do the over kill bit powerwise but this might not be a suitable model for that with it's already marginal wing area for a gas engine. Judging from the video I think that the 20cc engine provides the ideal power for that model. The Syssa is lots more powerful and with it's narrower footprint will certaintly make a much cleaner install, with no muffler or carb throat showing throught the cowl, but remember that it will need a fuel tank of more than twice the capacity of any 20cc's 8 ounce tank which will possibly cancel out the weight difference between engines. Something else to ponder, can your model provide the ground clearance that a 30cc engine size prop requires.

Karol

Karol,

Thanks for the suggestion. Being very new to Gas engines I think to built it with 20cc engine. Now when we talk about 20cc gassers, what do you suggest, Is Zenoah the best choice. Some one told me that it has battery issue with the ignation, if so, which engine should be lesser in weight and good in power. . .What do you suggest about the engine choice?

Thnx

I have the rcgf 20cc (aerovate). Like it a lot. I used it on my rascal110 and replaced a saito 120. I find that it flys the rascal110 about the same as the saito. The only difference is a little more weight with the gasser, naturally. As for the zenoah ignition current issue, got a buddy in the club that has one and it definately sucks the juice. He had to put a bigger battery on to get what he considers a normal days flying. Dont recall what size he used.
Edwin

In stock form the G20 is a very powerful engine for it's size but a big minus is that it requires a large capacity battery for it's rather power hungry ignition which adds weight, so in this case and for this particular model I would suggest that you opt for the RCGF 20 cc engine.

Karol

Karol - Thanks for the suggestion . . yes I was thinking about RCGF 20cc and as per the feedback, the only problem is the weight . . secondly when I look at the Epic Kit, it seems that the plane can be controlled with a 90size engine .  To be fair, I am considering RCGF 15cc engine ... I think it is lesser in weight and will have enough power for the plane. here is the engine

please suggest me  - -  should I order for this engine
