Bennett Built has tank fittings. Those fuji tanks are great! very light and leakproof. Saw many guys running them at Joe Noll last year.

Ok guys help me out, I have a brand new just built Kangke Howard DGA sitting in my shop with no engine in it. Do I put an OS G33 gasser in it or go with theDLE 30 like Im leaning toward ? Dont like what Im hearing about OS gassers.

go OS all the way (if you have the founds), OS is an OS[>:], you will get more power out of it compared with the dle 30

Power is not important if it has chronic problems. Considering how poor their service arm is (Hobby "Services"), they need to get it perfect. Lets hope DA decides to make a 30 something. At least in the event you have an issue with a DA (everything will eventually have problems) , you have smart people that make the engines actually answer the phone and make it right.

The Mintors are very interesting and inexpensive, comparatively speaking. I am in process of setting the 38 in an Extra. I have photos in the pattern forum, in the EF Extra 78" thread and in the OS33GT thread.

I hear the RCGF 32 is a powerhouse but have no personal experience.

For DA to enter this market segment they will need to have competitive pricing. I'm willing to spend an extra couple hundred for the power curve, reliability and light weight, but not every one is

Its so beautiful you'll fly the plane permanently with the cowl off and claim running in 5 years later.

The home for mine is on its way to me. Goldwings new Racer Edge 26%  hmmmmmm yum yum. I'll call her Maya

I don't care what the external parts of an engine look like, it could look like a turd for all I care. I want quality, properly selected materials machined to proper tolerances which I know OS are masters at. Destructive testing would tell the story for all these engines but I just can't bet myself to buy any more hobby stuff until I get rid of some.

whats to say the power curve will be retained in the 30cc class of engine. Smaller usually means more peaky relatively

Pat got tired....he does not want to do much here lately. Prolly needs a rest.Kinda miss that old fart!!!

So...any more real life performance reports?

jnred123

Texasclouds is right on, get this thing back on track I want to know how much power this thing makes, I'm just about ready to buy one to satisfy my curiosity but I just bought a PTE36 rear exhaust so I have to try that out first.

This video speaks volumes and at the end the pilot speaks about the engine. 3dhs planes have potential to fly extremely well in capable hands.

jnred123

Yes hugely talented flyer, the next big thing is the word, he is 17 and only been flying 3 years and the story goes he has never actually thumbed one in yet, only foamys and they dont count.
But we probably need a more objective viewpoint on the OS33 than a factory gun pilot .

I agree... and i hope we will have it fast i am
struggling between buying DLE-30 or OS-33....

Greg,

OS is not one of his sponsors, 3DHS, DA and Futaba yes. I don't think he's exaggerating about performance. He did say he had only two flights on it and it was obviously running well.

ghoffman

My Feedback: (3)

After he and others get 100 flights on it, then I might buy it.

texasclouds

Well it certainly flew well in flight. Since Futaba/Tower Hobbies/OSEngines are all kinda the same thing...it is possible that he didn't just get a random engine from inventory. However, OSEngines have a great reputation for consistant quality...soI don't think any funny business is going on.

It looks like a nice engine, and the video showed it could put out the power too.

jnred123

The way it was dragging that Slick around would suggest it has more grunt than a DLE30 and also the suggested props from the factory are all a bit bigger than the competition is recommending, I would just like to see a positive owner experience and some numbers after MATTK's issues.
I know Tower gets bagged pretty bad on most forums but I buy heaps from them and find the service great so I have no problem with the whole Great Planes juggernaut backing a young talent like Joey I think its great.
I am looking at it from a pattern perspective as well but my gut feeling is this class of gasser is going to just miss the mark, I went from a piped/pumped 160FX( I have never owned a 4 stroke glow motor) straight to electric which is really good but I would like a real engine again, the YS170/175 remains the benchmark power source for pattern.
After 20 or so flights on the PTE36 with stock muffler in a really old and heavy F3A airframe I think maybe it will come up short, but I have another lighter airframe to try it in and an MVVS tuned pipe so we'll see.
Even though the OS is side exhaust being the same bolt pattern as the DLE means there is heaps of exhaust options out there already which is good, getting a header for the rear exhaust PTE36 was a chore( a Webra 120R header fits if anyone is interested).
I hpoe its really good, I just can't imagine OS getting it wrong after the 55.

My OS Gt33 runs fantastic....

it has ldled and carburated perfectly from the first tank of fuel. You just have to remember to crack the throttle open a bit on startup or it may run backwards.

the muffler does great at actually doing what a muffler is supposed to do..... its' at least as quiet as my DLE with cannister exhaust.


i have not flown mine yet as i'm waiting for my 44.5mm standoffs to arrive so i can put the cowl on (the 5x44.5 standoffs will let the GT33 perfectly replace a DLE30 V2... same footprint, same length)

from ground testing the GT33 is going to be THE engine for 3D.... it feels directly connected to the throttle stick just like an electric motor. The throttle response is THAT good. My engine runs just as good as the engine Joe is flying in that video.

the engine also had a lot of compression even before the first run.... my DLE could easily be turned over by hand (and still can be) this OS engine just pops! using the exact same prop as i was using on my DLE (20/6 Xoar) i can tell the engine has way more power than the DLE... which is amazing to me considering the lightening fast throttle response.

price is right in line with a DLE too... i got mine for 369 from tower w/ free shipping (super saver 50 bucks off coupon) but i had to buy the OS standoffs so that added another 31 bucks.... still for the way this thing is running i am completely happy with my purchase considering the quality of the piece, the nice muffler that actually works and the proprietary ignition that will let you run up to 7.4 lipos without the need for a regulator.

I think OS nailed it on this one.

I'll be sure and post a report once i actually get to fly it.

selnekav

Hi,
Do you see any difference in terms of vibration level between the DLE 30 and GT33 ?

Thanks

Direct from the Tower site:

"Ignition Battery: 4.8-6.0V NiCd or NiMH, 6.6V LiFe or 7.4V LiPo pack
LiPo battery requires voltage regulator"

Do not run a LiPo without a regulator!

I noticed Joe's started backward too in that video! I was also impressed with the sound of their Pitts muffler; much quieter than most of the others I've heard on gassers...
