OS 33cc gas engine
Has anyone user / reviewed this engine yet? It is 120g heavier than the DLE 30 but has marginally more displacement

RE: OS 33cc gas engine
I have not ran this engine yet. But have seen this thing run (very impressive and sounds great) Aaron Bates who is a team pilot for 3dhobbyshop had one at are field the other day mounted on a 74 inch edge. This thing pulled it around like a rag doll.. Also comes with a pitts muffler and has a very nice sound to it..

RE: OS 33cc gas engine
Is the OS 33 made in China or Japan or Korea? Brian

Does it have a standard reliable ignition, or some one-off specialty created for OS that will cost more than the engine to replace when it dies?

Sensor: 33.99 (must be a really, really good one)
total: $123.98
See, only about double the cost of "normal".

RE: OS 33cc gas engine
Thats one reason I don't buy OS products look at replacement parts and you will see they cost quite a bit more than other engine makes. Here is an example,
O.S. Carburetor GT33 169.00, O.S. Crankcase GT33 84.99
Carburetor Complete DLE-30cc 34.99, DLE Engines Cylinder DLE-30cc 39.99 as you can see parts for the OS run quite a bit more than DLE.

One item of note on the 33GT is it will start far easier with a starter such as the Dynatron on 24 volts. The stock CDI requires a minimum starting rpm to fire, a built in "safety" feature (don't ask me what the safety feature is all about, I don't get that) It has more compression than the others so make sure the engine is wet and the prop is moved back before engaging the Dynatron; it will need a running start in other words. Good luck with it...
There was a learning curve with mine and I had an early break in the backplate that Hobbyservices repaired on warranty. But now, after some 10 hours of operation, I love the absolute brute power of this thing, its great mid range response and large popeller hauls (how about a 20x10 at 7300 rpm? On pipe tho.... expect a 500 rpm drop on muffler alone)

RE: OS 33cc gas engine
OS recommends a starter in their instructions, but don't misconstrue the starter comment...It doesn't absolutely have to have one to get going. I start it by hand often, but I use the starter to get going quickly...
Nevertheless, the engine is not as simple to start by hand as my SAP180HP or my DLE's are, at least not yet

RE: OS 33cc gas engine
I would think that if the engine is choked, it will start. Most I read had a problem with it running backward. Anyway, I have a DLE20 running now and first time in the day I start it on the field, I always use a starter till it pops and subsequently, it will start by hand every time
The OS GT33 is a ringed engine with a liner. That would be 'safer' that the DLEs which have no liner. So, God forbid, should you run it lean and wear the liner, cost of replacement will be lower- in the DLE you replace the whole engine casting
Also, for the same reason the OS would produce more grunt
I read in some thread that the ignition module on the OS is custom-made by Rcexcl, the starting speed was OS' requirement. I would think that a Rcexcl module would work just fine
All of these replacement cases are, ofcourse, if you mess with the engine, think MTX will agree

RE: OS 33cc gas engine
stop spreading this myth ameyam. Youd do not replace the whole engine casting with a DLE, just the cylinder casting. Your crankcase is unaffected.
Also you really have to run that engine very lean and for quite some time to do serious irreversible damage to a petrol engine. The fuel has alower solvency then alcohol so it still provides some protection.
I have never heard of anyone killing a gasoline engine through running it lean
