OS 22GT v Zenoah 20 v DLE 20 Which would you choose and why.
« on: October 09, 2018, 13:37:05 PM »
I'm a died in the wool OS fan and am poised to hit the button to get an OS 22GT from Just engines.
Apart from the fact that it's an OS one of the features that swayed me was the fact that it appears to be the only one that is supplied with an effective silencer.
I did look long and hard at the zenoah but the fact that an effective silencer is needed thus adding to the cost put me off.
I didn't look at the DLE as I've bought five, chinese petrol engines including one dle and haven't been wholly satisfied or impressed by any of them, but that's just my opinion. (DLE 32 , rcgf 32, turnigy 26, ngh 25 and an ngh 9 fwiw) Over to you........... :xx

I have used many DLE's and in my opinion, you can't fault them as long as you don't abuse then.

Can't fault Zenoahs either, though these days, although they are dependable, they are lacking in the power to weight to cost ratio.

OS, as previously stated, they are the Rolls Royce option.

How about Saito. Not the cheapest again, but like OS, sooooo well made and dependable.

Just my ramblings.

Iíve got a dle 20re that been faultless but it is a bit on the noisy side which isnít an issue where I fly. I also have a zenoha 20 which is a lot quieter on the standard silencer but not as powerful. The zenoha has had to have a new ignition module though. Iíve no experience of the O.S.

Charlie, used to have 7 saitos, 62s, 82s and 125s maybe its me but I had 3 of the 82s seize their conrod on their crankpins, all the 82s suffered from leaks on the carb to head tube and both 125s were like windy guns. I sold all but 1 82  and an 62 which is now in disgrace as the exhaust manifold unscrewed and got lost in flight and deadsticked, landing out in the rubbish which wrecked the model the other 82 has lain unused for the last 6 or  years, I vowed never to buy another . I might sell those two to fund a laser 70 if I can be bothered.

I also have a load of Saito's, even twin engine planes with them, the methanol versions are really good, but my petrol FG-30 is a  headache as it splutters on take off and now and then in the air, I would not recommend the petrol. versions,,

I have no experience of the OS GT22, but own both a GT33 and GT60. As others have said they are very well made.

The 33 and 60 are known for starting backwards.  I don't know whether the 22 exhibits this behaviour. This isn't an issue as you cut the ignition and swing the prop again and it starts forwards. I'm still in the running in period of both engines so can't comment on longevity. The 33 is more powerful than all similar sized petrol engines. I've yet to fly the 60 so can't comment on how it compares.

At this size another option for me would be a Laser 4 stroke 120 or 155, but I don't know what your application is.

I hope this helps.

Robert

Intersting comments on Saito's.

I have only owned two, a 60 radial which was a lovely engine which i have just sold, only to help purchace a turbine and an FG20 which again was faultless.

Again, just my ramblings.

I own a OS 22 and the Zen 20. Both excellent. Not put them on a noise tester but to my ears the Zenoah on the supplied pressed steel exhaust isnt that much louder than the OS, the OS style is more convenient ithough and I have actually put an aftermarket canister on the Zenoah (from Phil at Fighter Aces)

The Zenoah has proved super reliable and nice to use but in comparison to the OS feels a bit heavy and a bit down on power. I have the Zenoah on a easy flying winter hack type model and use the OS22 on a sportier model, it was great on a slightly beefed up Sebart Katana 50.

I'm so gratified to read the comments.
Blackbird I have a laser 100 that I swapped for an sc 61 which runs well, but it's mounted in a plane and I have my doubts about its ability to pull my plane around.
I've now had the opportunity to read the instruction manuals for all three engines, the dle is out of the running as the oil/fuel ratio is 1:30, the zenoah and os operate with a 1:50 ratio and will therefore run on the aspen readimix fuel, the zenoah is noisy with the supplied silencer whereas the os 22 isn't. The zg 20 also has the carb sticking out the side which isn't helpful, that and the £45 or so to buy a half decent silencer puts it within spitting distance of the os costwise so if I upgrade, it'll be the os for me.

All the Petrol engines in our club run on the gardening centre ready mixed fuel, 
 of course with the exception of ME  :'' I mix my own, 3% Motul 410,,,
 So next step is hearing from you on the running in and flying with the OS 22 GT  :co




 correction,,,

Correction on the ready mixed petrol in France, most shops do their own, Stil is 2% and the
other Garden centres and tool shops are between 2.75% and 4%.
 anyway what's stopping you from adding 1% oil to the 2% mix ?, $%&,,

Ok I know you want a good excuse to buy an OS 20GT  :co

My experience of the 3% mix is the model gets black oil spots all over it. The only engine I have with a recommended mix of 2% is a turnigy 26S which is a cracking engine btw just so flimsy.
So if I wanted a chincrap I could use that as it is so much lighter than comparable engines but once again it needs an aftermarket silencer to keep the noise down which would mean butchering the cowl even more on the Tigre which I don't want to do.
As it happens the ngh is performing faultlessly at the moment (I may regret writing that) and I've got that on 2% to keep the sh!te down. It'll probably self destruct as the conrod is a known fail point but that's a bridge to be crossed at some point in the future.
