RE: DL-50 engine
Hey guys, just received my dl 50 today
Can I rotate the carb 180? This way i wont have to mess with miving my throtle servo set up. Bob told me to get the 8mm bolts with the 0.8mm thread pitch. I am using the standoffs that come with the engine. Also read somewere in this thread to remove a spring off the carb, is this the spring on the opposite side were the throttle servo hooks up? It almost appears that you could hook up the throtle servo on either side of the carb? Any input would be greatly appreciated.

You want Metric 5mm 0.8mm thread pitch , dont use 10-32 size, they fit, but the thread is not as tight and you will likely have problems with the bolts coming loose.
You dont have to remove the spring, it is only a light load and shouldnt worry any half decent servo. Some leave it on so that if a throttle linkage breaks, it will return throttle to idle/cut engine. Just unhook the spring off the throttle arm, dont remove or cut it in any way.
Cheers!

Yes you can rotate the carb, rotate the whole assem, including the reedblock.

Thankyou for the info. I will get the 5mm.8thread pitch and rotate the whole assembly, and will only unhook the spring!! thanks again.

RE: DL-50 engine
Dont' remove the throttle spring. If needed, clip it, but do not fully remove it otherwise your butterfly valve will eventually wear out, and you will be needing a new carb. With the spring removed the valve vibrates against the carb walls and wears out.

RE: DL-50 engine
Can I use a short (3 inch) servo extension to go between the ignition and the Hall sensor without adverse effect on the engine? I would like to mount the ignition in the fuselege just behind the firewall. Plug wire is long enough but the sensor wire is a couple inches short.
Thanx
Thanx

RE: DL-50 engine
Just curious, upon first inspection of the standoffs, I initially thought that they were threaded all the way through, but upon closer inspection I noticed that they are only threaded on the two ends. What kind of connection are you guys using on the fire wall end. Is it ok to go ahead and use same connection as up front?

RE: DL-50 engine
Finally got to do my maiden flight today with my DL mounted in a GP Wagstaff 300. I had run almost a gallon of fuel through it 2 months ago on the ground and tuned the engine. Afterwards I had run it dry and set it aside until I had time to finish the plane and felt confident enough to fly it. I could not get it to prime at first so I pulled the cowl off and put a small squirt of fuel into the carb. Then it picked up prime and took off. Put the cowl back on and it ran like a champ all day. One of the other guys with a DL remarked that mine runs smoother than his with next to no burble in the mid range and wanted to know how I tuned it. It's my first gasser and I found it too hard to try and tune by shutting it off to turn the needles so I did it with the engine running and the cowl off just like I do with nitro powered. I guess it did the trick as it purrs like a kitten. Can't wait to see what it is like once it is broken in 'cause it pulls my 17lb model around now like there's no tomorrow. Here is a couple of pics of our planes with the DL's

How did you attach to the firewall. I have the same plane and installing the DL50 as we speak, cant wait to fly her. How does she land?

I used 3" standoffs and 5mm hardware with extra large washers behind the firewall. It lands like a kittycat at a slightly elevated idle. I'm guessing about 2000 rpm. I was surprised at how easy it was to land. The standoffs were made my Roger Forgues.(Forgues Research) He posts here on the forum.

RE: DL-50 engine
Thanks for the info super08. Iwill use the 5mm hardware that I purchased as well. Just wanted to make sure before I procceded. Cant wait to get her in the air.

When I first started running this engine I was only getting 6400 to 6500 with a Bisson pitts and a Xoar 22x8. I tached the engine today and I see it is up to 6900 now. Getting better all the time. Started on the first flip this morning too.

Super08, what airplane do you have for your DL50? I used to have a GP Yak 54 but I sold it to a guy here in Moose Jaw. Now I'm looking for a new plane and a new DL50. Unfortunately here in Canada there is not as many good choice. I was looking at the WildHare Edge V2 but the shipping would kill me.

RE: DL-50 engine
I posted a pic of my plane 6 posts back, it's a Great Planes Wagstaff 300S. I also have a Giant Stinger for my other DL which I am not finished yet and Sig Spacewalker 1/3 scale kit I am going to build over the winter. Shipping is just something you have to live with. For oversized kits it costs me over $200 to have them shipped plus brokerage fees coming across the border. Not as bad if you can find a Canadian store that has what you want such as Great Hobbies or Hobby Wholesale in Edmonton. Good Luck.

RE: DL-50 engine
I just placed an Internet order at Thunderbolt RC. Unfortunately they did not have an Xoar 22A PJE prop in stock,
so I bought the 22B.
I also bought a white Sword 22x8, if I get close to 7000 rpm on the DL 50, it should pull around 25 lbs of thrust and that should make my 16 lbs Pitts Special accelerate strait up with smoke on, like the space shuttle. LOL!!
I also borrowed a Pro Zinger wood 22x10 prop, so I will be able to compare the Xoar 22B (22x10) against the Pro Zinger and will report my findings.
This will be my first large 68 inch wingspan gas plane with a lot more thrust to weight ratio, cant wait to fly it and do some tumbling, as the Pitts is suppose to be one of the best tumblers in the RC world.

You can never have enough power, as you can always throttle back.

RE: DL-50 engine
I've got about a gallon thru my DL. Still runs slightly rich. It seems I have to adjust the needles after every run. It burbles at mid range but is fine at low and high throttle. I checked today and with a Vess 22B I got 7100 rpm's WOT with 1700 at idle. This is with a Jtec wrap around pitts muffler. I've got mine on a PAU Extra 330 that weighs in at 15# 13oz. It's a rocket. I will hover at less than 1/4 throttle. The darn thing starts on the 3rd or 4th flip cold or hot. Seems to be a pretty good engine so far.

Hi, you mention Bob in your post. Is he the DL agent in the US?. What is the approximate price of a DL 50 and do you know if he ships to the UK?. I don't think there is an agent here yet.

I have the 88" Yak and 88.5" extra both with DL's on tuned pipes. I've been flying 30 years now and they are the only airframes that make me laugh out loud with their capability and manners....best out there...period.
The extra is a slightly lighter airframe than the 3d yak monster
i love them both and they are all i have flown for the last months..my QQ yak, Cap-X and comp arf extra havent been out the garage since i had these...lol!

Wavy777,
Do you get those plane from USA or UK. In my case, I have friends south of the border that I will probably go visit this summer so I should be good. I'm looking at the Wildhare edge 540v2, but the Extreme flight could be an option.

What tuned pipes are you using and have you ever taken any noise readings on them? I wonder how they compare with a cannister setup; I am using KS cannisters on my DL50s and 100 and they are reasonably quiet, but interested in maybe using a tuned pipe.

RE: DL-50 engine
So i was going to mount my dl50 on my yak but i have one problem, on the firewall there is a cross but it is not in the center, so should i mount the engine on the center of that cross or should i mount in the center of the firewall???
(The template for mounting, the anotherone is the firewall with the circle in the center .)

RE: DL-50 engine
Center your engine on the cross. It is supposed to be off center to make up for the right thrust that is built into the firewall. If you look closely you will see it is angled to the right and the cross will be to the left of center. What this does is move the back of the engine to the left so the front of the engine comes out in the center of the cowl.
