Would 1/4" G10 board be acceptable mounting material? And can you bolt directly thru the mounting tabs and thru the plate to the stand-offs or do you need to have the engine bolted to the plate and the plate then bolted to the stand-offs?

I have mine mounted to DAstyle standoffs only right now, but if a re-inforcement plate will give a little protection from a nose over or strike, I am there.

Sure would be nice if the plate and standoffs could use the same holes...then the drill pattern wont have to change.


My carb is defective from the factory, the main jet is plugged and 150psi blow gun cant open it up, I tried using a sewing needle....no way.

The little brass jet was pressed in the wrong way and never flowed fuel. I need a carb body.....took a another off a DA and will run towmorrow , but I am short a carb.

It just figures , everything else is OK, but the Walbro. Lucky me.


The reed block is completely different than the DA...the DA is a square 4 petal reed block...1 reed per side of the square.

THe DL is rectangle with two reeds per side. Same reed area.

I found a bad reed while taking the carb off the DA...one was sticking up a little...that is why this motor was deadsticking before I took it off the last plane it was on. I flipped it over and it sealed. Glad I took the carb off for the DL.....

I wonder if RCIGN1 could drill out the carb for you or if he would know what size broach to use.

Tough luck Bosshoss.... must be a first!?

I think the mounting plate is a great idea.... is it new? To be most effective in protecting the engine from bending forces in the event of a noseover or worse, it should use seperate mounting holes for the standoffs, otherwise it would just be another spacer..... if made in thick good quality plywood that should be fine...(or better?)

Most birds dont have alot of room for a wider pattern.....so the holes would be inboard....eh?

THen that would cut into the carb hole area.

MAybe flush mounting to the firewall with carb throgh the hole in box would be best.

Quite a few birds used to be done this way,,,,,eh??


Someone who as the right press and parts could fix this carb body...it was just assembled wrong or a burr got in the main jet hole.

But, this carb is much much cheaper than the DA carb. Plastic hose connections vs. metal ones.....also the main jet on the DA does not have a plastic insert , is is all brass.
Also the DL carb has a spot of glue over the main jet , in the bowl....it looks like the DA carb is hand peen'ed...no glue.

So , on the outside from 10 feet away....this LOOKS like a DA...but anywhere cost could be cut.....it was cut. JMHO. I am not dissing the engine...it is what it is....the main factor is ............

IT RUNS.........can't wait for for throttle in a few hours. If it runs up....It will be airborne after one more tank. I had to stay up late last nite repairing the hack job I did on the fuel system of the test plane for troubleshooting.

You know the drill....first take out the filer, take out the T, cut this line put ihere..ooops...cut the T, run one lie no filter to the carb...I went through every progression hacking up the fuel system to figure out what was wrong....

HaHaHa....bad Walbro.

sounds as though the carb may be a copy rather than a genuine Walbro then.....? I wouldn't know as this is my first venture into petrol engines...but it seems to work OK if you get a good one.

THis was a genuine Walbro , complete with part numbers. THe main jet was not seated ight or oriented correctly. I found a little cut up plastic in the jet but was stillunable to clear it.

No Biggie, my carb from my DA set at LSN+ 1 3/4 and HSN at 2 was perfect and did not need any further adjustment.

I have video of my maiden flight with it, rolling on take off violenty, and 3ding almost immediatley....well, at least my version of 3D..

It spun a Menzs 22 x 10 at 7050 on a GloBee tach. Lawnboy 32:1.

Idles very reliably...and in the video you can see me going around three times going lower on the thrott trim every pass to slow it down. 10 pitch is #$%#$%.

Can't wait to throw a 23x8 after a couple of gallons. No hint of kickback, predictable starting.

A-OK.

Video later tonite...I am a newbie at video authoring....

BSV8,

Sounds like you might like it. Are you using the muffler that came with it or a DA?

My first attempt at making and posting my own video.

Laugh away...I cut out the parts of my nose running, and swearing and trimming out the plane!!!!


Not much here that I could post but more on the way with a better prop this afternoon.

Check out the snaps on the go-rounds and takeoff....the hover was out of focus...sorry....more to come

Looking good Boss. I put several flights on my dl50 this weekend.

I used windows movie maker....storyboard and timeline...I am newbie at it.

I can;t seem to figure out what setting on the camera for the autofocus to quit hunting after you get far out.

I used a MenzS 22 x 10 and I had a hell of time getting it to slow down.

I flew a few more times after that flight, and even deadsticked it, after bringing the idle down ,click after click , on landing go-rounds' .

That 10 pitch prop was given to me by a friend...now, I know why. I was just at the field , but the wind was terrible, so I did not even unload. When i can, I will sit in the easy chair at th field, and burn 2 or 3 gallons just floating around...so I can get to AMsoil 50:1 on her.

Then she goes in a Aerotech Pitts M-12 Python.

Now , what would be a good 50cc twin engine airplane to play with??? Gotta go looking .....

note to DL Power: just send me a crate of these.

22x10s work good on biplanes, they balance out the extra drag well.

I like that python, be sure to start a new thread and keep us updated on that plane. Keep your reports coming on the DL50, I'm just about ready to grab one...

Well I sent my new, unstarted DL-50 to RCIGN1 to play with. He should have it before the end of the week. I am looking forward to his opinion on the thing. He said he will post his impressions here for all to see.
