DL-50 gas engine
#52
Hey guys...
Thought I would show you my rig for a Top Flite Mustang including my DL-50.
This isnt the finished configuration, but you get the idea.
This engine has been run once on the bench and started after 5 flips with choke, 1 without.
Cheers

Hey guys...
Dart is right, its a [link=http://www.keleo-creations.com/]Keleo[/link] muffler putting the pipes in the scale location and makin' em work
The prop assembly is from NRG [link=http://www.soloprops.com/]Soloprop[/link] and is pitch adjustable to whatever you want. Final blade diameter about 20".
The muffler needs to be modified a little because of the prop drive extension, but nothing a little aluminium welding wont fix.
There is some more pics of this in my [link=http://www.rcuniverse.com/forum/m_6457176/tm.htm]build thread[/link] at the end of page 2 if you are interested...

Can't believe we are into another thread after being locked on the other one!! Anyway I have 2 DLs, the first one is a year old, probably at least 10 gallons through it and still goes like a train - 7200rpm on a 3W 23x8 on a KS Cannister. Second one has about 2 gallons and pulls about 7100rpm on a Menz 22x8, again on a KS cannister, both on synthetic now. First is the old version, second the new one.
Great engine, easy to use, repair and everyone who has seen mine are keen to get one. Unfortunately we don't have a dealer here, tried to set one up but couldn't make it pay with all the import duty etc. Would recommend this engine to anyone, especially if you don't have the ready cash for a quality engine like a DA.

I should have put, that the compression is less than my 3 DA-50's and one of my friend who has my gauge and checked all of them. I am not saying it is better or worse. Just fact. More compression does not mean more power.

You wouldn't happen to remember the PSI numbers?

Hey guys, I'm in the process of builing up a 1/3 scale pitts (no particular plans)I'm making alot of modifications, to fly the plane better, not just scale but all around better handling. I also am planning on using the latest version DL50. I talked to Bob at DLUSA, and he said the prop hub to the back of the standoff measurement is 6 7/8" ,but he was a little vague in being sure. And since I haven't constructed an engine box yet I was hoping to have someone here verify that deminsion so I can make the box to fit that engine ,with out spacers etc.

V6goose,
I have a 50cc with that same Kelo exhaust and a Solo prop 2-blade..... BUt I didn't want to go and try a 3-blade,,,, (let alone a 4-blade) set up,
Due to the worry that it wouldn't pull at all!!
Have you flown with this set up yet?? I would be very interested in you results..... Not doubting in anyway.... I just wish at times I would have went with a 3 or 4-blade.....

ALso....
I am new to looking at other alternatives other than the HIgh buck engines.......
I have been taling to many people that have factories in CHINA...... It is a fact that China has some of the most up-to-date state of the art factories in the world.....
The TOlling equipment in made in swiss and shipped to China.....
It is not wonder that they have brought a very well made engines over seas lately.....
Has anyone used the MT-50NG engine from TomyRCModels ??
Is this the same as the DL? or is it like the SPE engines??
Thanks for the imput.....
Justin

Hey Justin...
I haven't flown with this setup yet but hope to this summer. There is no real information on this setup around, not that I have seen anyways. Plenty of doubters so we will see what happens for myself.
Good luck with yours

I started at about 1.75 on high and 1.5 on low. That will be way rich. Tune from there. I'm at 1.75H and 1L right now. Still too rich but flies with lots of power andf fast transition. It misses in the mid range to upper and I think it's because the high needle is way too rich. It should probably be down to 1.5. Also it's still 4-stroking at 1/3 throttle and down. I think I'll leave the low end alone and lean the high needle. That will probably help lean the low as well (a little at least).

It is my first gas engine to go with the Yak 54 89" wing span. I really don't know if it is the newer version. I fly at Marymoor park in
Redmond and several members have this combination which looks to be a good match.

I have a buddy of mine who I fly with 2-3 days a week and work with 7, he has a dl 50 on a hangar 9 27% with 2 4000mah lipo and regulators, all hightourque sevos. IT IS INSANE!!!, I have never flown a plane that I felt was just flat out evil, but this thing takes tha cake. EVIL i tell you....pure evil.[>:] Im not positive on prop but it is the recomended, or one of, and is a mejilik(sp).
hovers in at 1/3 throttle,and according to a bushnell radar gun can vertical climb from deck out of a hover to out of sight and hit about 55 mph UP LINEING!!
I mean its a light plane and all, but that engine outperforms my da50, Similar setup, but wow, My next engine will be a dL, and for he money, buy 2, one for parts, then a few months later youl just put it in somthing too!....

I would choose a DL-50 over a DA-50 for the following reasons. The DL-50 is cheaper. The HP rating for the DA is 5 hp where the DL is rated 5.2 hp. With respect to hovering, my skill level is not up to it. Anyway, it will be fun trying it with lots of altitude first and then
dropping lower as I get the confidence.
