The graupner 15 8 3 is the prop you want, it has a wide blade and is quite efficient unlike a mas. Expect about 8000 rpm from it.

Not having much luck finding one in that size, those I am finding are 11" and under. Reason Iam considering the MAS is I can get it quickly from either my LHS or Tower, though with the LHS it took 3 times as long to get my last thing than it would have from Tower.

NM found it finally, Not cheap thats for sure, nearly twice what the MAS is.

acdii, I have MAS 16-8 Three blade. Old one turns 8,200 rpm with DLE 20. New one which is redesigned turns 7,400 rpm but does not loose much thrust. I have a Graupner 15-8 three blade on a DLE 20, it turns 8,600 rpm.

Well this is interesting, just browsing sites for DLE and came across the DLE page. They say props down to 14x10.   Anyhow, I have a 15 3 blade enroute and will see how it works. It would be nice to be able to land without striking the prop.

I'm just about to start my DLE 20 for the first time and have a couple of questions.
Mineral or synthetic and is it OK if the oil is a couple of years old but has been kept in a sealed container?

Thanks
Falcon

I have an interesting 'new' problem....I switched the throttle arm to the additional one (longer) that came with the engine....it was difficult to get the screw out of the original but now when I tighten the new one, the throttle will not move! Suggestions?

Did you push the new arm too far down on the shaft before you tightened it and it's hitting the carb body? Loosen the setscrew, pull it away from the body and tighten carefully and try again.

Thanks Bill, but I removed the engine from the plane and reinstalled the one that was originally on the engine and I can bearly move it. I removed the spring from the other side hoping it would work easier - noope

Stuck as it takes a LOT of force to move the throttle. Even took the screw to the orginal arm out and with only the arm, can barely move it. Wasn't that way when I opened the box

tailskid - try taking the throttle plate off. Maybe you pushed the axle a bit and the plate is binding inside the carb throat. And, as Twin Flyer said, I've also pushed the throttle arm down too far before tightening, causing binding between the arm seat and the carb. I doubt you bent the throttle axle.

Looks like OS's pricing (on TH, anyway) for the GT-33 is not too bad - after the TH $50 discount, the GT33 is $350 - which is still $80 more than a DLE 30 after discount, but the GT33 comes stock with a Pitts-style muffler. If you add a Pitts-style muffler to the DLE 30 that adds $75 - bringing the engine to equal pricing. Of course, this doesn't take into consideration any quality issues. Maybe someone can comment on the quality of the OS engine - I'd suspect it's very good, going on their Nitro engines, but that's just a guess.

But their pricing for the GT55 is double the DLE 55 (which get's rave reviews here on RCU). After TH $50 discount, the GT55 is $599, where the DLE 55 is $319. And you still have to buy a muffler for the OS55 - another $90. So now we're talking $319 vs $690. HP numbers, for what they're worth, are very similar. Does anyone have any idea why OS would price their 55 so high?

You're aware there's a new DLE just now being introduced? Not a lot of "in service" reports, but there's info floating around. If you're in the market, look for info on the DLE 35R - it's a rear exhaust engine as well. TBM put a price on them.

Still can not get the throtte to work smoothly (as easy as the choke)....anyone help? It takes both hands to move the throttle from idle to full!!!!

Jerry

PS I pushed from the bottom and pulled from the top and it is getting a bit easier, but no where near what it was.

Here are some pictures of the carb closed...it doesn't look like there is any evidence that the plate is binding but I may be in error.

Thanks for the advice microdon2!
