I'm looking for an engine for a 120 size 3d plane. I'm thinking of buying used and it seems like there are a lot of Saito 180 engines out there that are used, More then other engine brands. Is this good or bad? I have never owned Saito engines but most people I talk to like them. I own OS and YS engine (both I like very much) how will the Saito compare? The people I know with Saito engines only have them on scale war birds and trainers, so I never get to see them in true 3d action. I love my YS 110 it has so much power with a great throttle response! Will the same be true with the Saito?

A YS140 slightly out-powers the Saito 1.80 at about the same weight. Saito 1.80's are very good engines though. If you get a good deal on either one, take it.

They shake like crazy. Also, any Saito over 1.15 in size doesn't really "jump" a plane out of a hover. To me they seem to have retarded throttle responses at the expense if great reliability.

As ThumbSkull said, the smaller YS has more "oomph" as it really benefits from the pressureized fuel delivery.

I love my 82's (which also shake like crazy) but they run forever and do wonders for a 4.5 lb 3D plane. I also love my 100 on a 5.5lb Mojo 60. I even love my 1.25 on an OMP Fusion (~7 lbs) but it just doesn't snap around like the smaller ones even given the slightly larger size factor. A YS 110 is way better for the same size.

I put a 180 with a Menz 18x6 on a 10 lb Funtana 90 and although big and loud, it never seemed to act like it had the power in transition. I also replaced all the CA hinges with dubro steel pin ones and got rid of any plastic servo arms cause that motor pounded everything into submission.

The reason there are so many 1.80's on the market for sale used is the Syssa and DLE-30cc gas engines.

Would the DLE 30cc engine make a better 3d engine then the saito?

Yep, got one on my Funtana 125 and love it. It does need to be a DLE30 V2 though, the older side carb models had some issues. The Funtana is a 10.5 lb plane and the DLE will pull it out of a hover faster than some sport planes take off down the runway.

I have to admit the DLE 30 interest me for two reasons, 1-low cost to buy new, 2-low cost to run (gas). Is it reliable? What about the DLA 32 engine? It looks alot the same as the DLE. Is it the same engine?

just fly statio so you can spit all that nasty **** all over your plane and buy 30 % nitro like it's going out of style

Clean would be nice and lets face it I'm looking to cut flying cost. Times are tough and I want to keep flying, but the nitro is a killer. I was thinking of going with a Saito 180 used and later converting it to gas, but I never really looked at gas 2 strokes until now. When I first started flying they were only used on gigantic planes that had more in common with flying Elephants then aerobatic planes. But I see now days that the gas engines have more power and alot less weight. How small of a plane can the DLE 30 be fitted to? Some of my planes take only up to a 120 4 stroke and have wing spans of only 64", will the DLE 30 work here?

DLE 30 smallest airframe ?? not sure this thing is a vibrates my friend and it's big

25 % airframes ruflly are powerd by 30 cc's i wouldn't try to stuff a big gas engine in a super small airframe for 3D .. it's not goign to be fun honstly if i want small I'd just go to the medium electric's they are really hard to beat


if i want cheap i'd fly a nitro profile kit built one so it's tuff

So it looks like gas is out for now, I don't want to change all my planes. Does this mean the Saito 180 is out as well? it runs about 31oz in weight.
I have a few 65" wing span planes with no engines and I want to get one going and use the others for back ups for if I have a crash. The only reason I'm looking at used saito 180s is because they are cheaper then used 120 engines, and more common forsale used.

Look for an OS 160 or Moki 180 2 stroker then. They run balls to the wall on affordable 5%

TRY THIS

I am a huge Saito fan and own several. I am not however a 1.80 fan for 3D. The DLE30 or Syssa30 would be much better suited. If you have to go glow and want it light, the OS 1.20AX will swing a 17x6APC with authority and be much lighter.

Actually the DLE weight is 36 oz ready to fly with muffler, ignition and all. The OS 120AX is 31oz with muffler leaving the DLE with a weight penalty of 5oz. But wait, the DLE only uses about half the fuel of the glow for equal runtime so less fuel is required on board. 16oz of fuel weighs approx. .85lb or just over 3/4 of a pound. OK here is the kicker, half of 12oz is 6oz so we're already lighter than glow after the fuel is factored in. I only needed to make up 5oz and I have made up close to 6. Also, the DLE will swing a 19X8 with authority and make over 20lbs of thrust doing so. That my friends is incredible thrust to weight ratio on a 120 size bird. The DLE20 will hover a 10lb plane nicely making around 15lbs of thrust. It weighs in at 28.9oz ready to fly for those that need something a bit lighter than the 30 and and runs real sweet. Very fuel stingy too needing less than 8oz of fuel for a 12 min flight. On my DLE30 powered Funtana I use around 6oz to do 10 mins of 3D mixed with some IMAC type flying.

What about using the DLE 20 on my planes? maybe this is more the size I need for planes with 65" wing spans? Also the Turnigy 26HP engine that zacharyR posted looks very interesting. Would these engines also work on 90 size planes?

a DLE 20 is a powerhouse, and id take one over anything turnigy anyday

i think you are on the rite tack looking at the small gassers.glow fuel is getting higher in price everyday and glow engines prices are going down.i have more than a few saitos,ys's and can't even get less than half the new price for them.i have a Fusion with a ys110 and a Mojo with a ys63 and love it,but hate to pay the pice for 30% fuel. when your looking at a big block glow i think your better off with a gasser.

The only great 20cc is the DLE. At 30cc two are great, Syssa SAP180 and DLE30.
There is more to gas engines than just looking at the cc's. The DLE-20 is a bit more power than a Saito125.
The DLE-30 is just a bit more power than a Saito 180 and more responsive.

Jezmo, I was comparing the OS to the 1.80 Saito. "if you have to go glow etc..etc..".

Sorry David, I didn't pick that up. My bad. At least we have some numbers for them to crunch now. Have a great one man.

All good info, Thanks guys.
It sounds like DLE 20 is the engine to use in my situation.
What size battery is recommended for the ignition and how long will the engine run on it?

800-1200 mah is all that is needed on a 4.8 pack.i can fly most of the day on that and drain the battery down to 3.5 volts before it starts to miss,with a rcexl ignition.

Thanks Gezmo. Sorry if I was a little testy. Tis the season.

  I have a Dave Patrick Ultimate and I was thinking about putting a 20 DLE on it. Does anybody think this is to small of a engine. I also have a DLE 30 in the hanger I could use.
