my crank sensor seem to be set about in the middle of the adjustment slot.thow this might not mean mutch to many varribles .just a small differance in the way the hall sensor is glued into ist housing would change its locatoin.(GOOD idea to set the timing thow bet they dont do that on evry one)still mine is running fine . i have the timing range on most ingins ot be 28-32 deg.i find the best way is to set for max power then back of a bit (watch thoes fingers when playing with timing )

RAMMJETT

be sure to do this with a degree wheel so you dont go out of range (not good for engine or fingers)

Dzien Dobri Pawel!

I now have 3 DL's, one still needing an airframe, i am a big fan of these engines. I have had good results with a Mejzlik 23 x 8, but also a wooden zinger 22 x 10.

I run a KS tuned pipe on the 23 x 8 DL (EF yak 88) and a pitts muffler on the 22 x 10 (AW 260 QB).

If you get stuck for suppliers of bits in Poland, PM me and i'll send you some web links for what you need.

Got it Bob. I had already figured that out last night. I also moved the ball link to the outside of the control arm. This puts light pressure in on the throttle rod. There is a c-clip the keeps it from moving to far on that side and now the throttle moves in the same postion all the time.

Thanks

It should be "Dzien dobry" but nice to read even this Do you speak more polish or just this ?

well fellers, I just hate myself for saying this, but the devil has a grip on my throat, and is threatening to rip me if I don't. Weather this morning at the flying field was 70, wind straight down the runway, 8 MPH, overcast, so no sunburn, and I got in a few flights!! so there ..... hehehehehe[8D] ... and tomorrow is supposed to be better, soooo hope to tear the sky apart with my GA/DL 50 combo.

eat yer hearts out all you nawtherners!!!

That' cruellllllll. The snow has almost melted at our field. Now just need about 30 more degrees.

Hi Guys,
I am building a 1/4 scale Waco and I will be putting a DL50 in it, this will be my 1st gasser. Can you recommend what size tank I should put in the plane for this engine? I am estimating the final weight of the plane to be between 27-30lbs. I hope this will be enough engine to fly the plane. I am not looking for unlimited vertical just some mild scale Waco aerobatics.
Later!!

16-20 should be lots.ama states 12 lb per square inch of engine.but by planes have a lot of drag i have few.wing loading should be good but man you will be working that engine.make sure you try it on a calm day just incase.i am intrested in hearing if this pupy can pull it thow

RAMMJETT

i was worried about my new scratch built super chipmunk DL combo it is 1/4 scale1750squares 106 inch wing but it only weighs 19 lbs.just waiting for the snow to melt.jujing by my other dl i dont think either of us will have mutch of a problem they have wicked power.

RAMMJETT

aa2dd i have a GA a well how does it fly with the dl .used all my dls in other stuff .i keep looking at this 75cc twin gasser only weighs 5 lbs and turns a24x10 @7500 .been under the bench forever. i am into mostly big stuff now.but having lots of fun with thies 50.pretty near cheap as foamys

Anthony--Hi--saw your post about the Waco. I don't know if the DL will enough go power for a 27-30 lb plane. Would probably fly a cub that big, but I don't know about a Waco. Maybe one of the more knoweldgeable gas guys will respond.

How about it Bob Pastorello?

WacoNut

Are you saying a 16-20oz tank?? I was thinking a minimum of 24oz?? The add for this engine says 30lbs of static thrust I would think that would be more than enough for a 30lb plane. I am also going to add a smoke system, any recommendations on a smoke tank size for approx 5 minutes of smoke?
Thanks!!

Hi Greg,
I am building from Pepino plans and the plans call for a ST2500/Quadra42. I am hoping the DL50 will do it as the order has been placed[&o]

OK--Anthony, I would bet the DL pulls more than either a ST 2500 or Quadra so you'll be fine. My Giant Aeromaster has a 24oz tank and I am expecting 2-3 flights on a single fill. It's one of the things I will check before first flight. Count how many cranks to fill tank; fly normal 10-15 minute flight; de-fuel and count how many cranks. That will give me a good idea about how much fuel it uses. Probably guys on this forum that already know. Everything on this thread indicates the DL to be very strong and light. I have only run a single tank thru at about 2500, per Bob Kramer's instructions. Took two sessions of about 30 minutes each--but that's just a fast idle.

WacoNut

I think I will be fine also, I am just looking for some good sport flying no 3D. I just don't think a Waco would look right in a hover
Anthony

RAMMJETT

yeh 16-20 oz go bigger if you want .thies things are misers.i fly for abought 10 min and only use 8 or so onuces.i forgot to ask not all waco planes are biplanes is yours .and by the way on a digital fish scale. static thrust test you will get 23-25 lbs.give or take .i have 50cc pitts 16lbs giant aero most fly 50cc 19 lbs.at 30 lbs with a 50 cc you wouldent want too mutch wind at your back

RAMMJETT

trust me when i first flew 1/3 pitts special 1 used a quadra 42 was way to scale for me and it was 17 lbs with that engine .according to the figures weight&power you would think i could rip the wings off that plane with a DL 50 but it dosent work that way with big by planes lots of drag.now saying that i dont know if the weight makes that mutch differance never had one that heavy with a 50cc guess you will find out

WacoNut

I guess we shall see,
I have the plane all framed up and I am working on installing the controls, landing gear etc: I am still a couple months away from the 1st flight.

DUBNUT maybe you could answer a question for me is this the YMF-5 1/4 scale i have some plans given to me by my old friend GREME MEARS.after i saw his plane i just had to try to make one.did you have to mod the plans mutch or built it straight up i just wanted to know what to expect for weight and how you got to 30 lbs

TOYMAKER

My Feedback: (6)

I am running a 16 oz tank in my Ultimate and I fly 15 min and have about 1/4 to 1/3 tank of fuel left depending on how I am flying the thing. I think 20 oz is a tad overkill.

The Pepino plans are notorious for having alot of errors,
I had to correct the wing ribs, fuse formers, Stab and elevator shape and a few more things I can't think of off the top of my head. Another guy on RCU has one that he just bought from another guy with alot of scale detail on the plane and it weighs 23lb minus engine and radio. I am guessing 30lb on the high end flight ready. You can check out the Pepino thread in the scratch building forum.
Later!!

Thanks for the tip Wayne,
All I have to go by is my Weedeater I know that thing will wear me out going through a tank of gas.
Anyone have any advice on a smoke tank size?
Anthony

I also have a 16oz tank in my 16.5 pound SD model yak. That size tank is great, I think. About 10min in the air and it never runs out.

the GA flies great with the DL50. When I bought the GA/Dl-50 combination, I was a bit nervous about whether I would have enough power! I now have about a gallon and half of fuel run through the engine. It is starting easier and sound smoother now. It hauls the GA straight up ... outta sight if you wish it to. It has more than enough power. Mine will hover the bipe at less than 1/4 throttle. So far, the DL-50 has awesome power!
