Hey Andy, guess what.....I get back tomorrow and the DA50 is at home AND the DA100 will be there wed!!!!! Can you tell I am like a kid at chrismas???

Oh and if anyone is in the Frankfurt/Hanau area, go to the 3W factory. One word......AWESOME!!!!!

you are a kid. welcome home.

anybody tried 3d with this thing if so what engine?

Same here too!! I am also a kid at heart.

Hats off to you Swift Bill !!

I got to fly my Patty yesterday. This plane is awesome! I do have a question for those Moki 2.1 users out there. WHat is your top-end coming out at? I have just over a gallon of 5% through the engine and I am only getting 7,000 out of it with a JZinger 20X8, K&b-1L plug, and a Perry regulating pump. Are you using large fuel line? What am I missing? will it get faster with more break-in time?

Thanks in advance.

What muffler did you get for the DA 50? :

If you can make the engine go rich at full throttle, the fuel tubing is OK.

If not, you will need to go into the tank and change the aluminum tube and the interior fuel line to something larger and drill out the clunk.

Also, the Bisson HIGH VOLUME pitts for the MOKI 2.10 adds a couple of hundred RPM.

And finally, Zingers tend to load down the engine more than other brands.

Okay, so your home now. It's 12:10 CST where are the pictures!!!

Just pile it all up snap a few and lets see them.

Andy

It sure is nice to know that there's a max rpm with the Moki 2.10. But RPM doesn't mean a thing. As an example I have a Moki 2.10 with no pump, regular fuel line, no drilled out clunk and 126, 13-14 minute flights, and it definately depends on the prop I use for the performance I get:

Zinger Pro- 20X10 - RPM 7200 - Poor Perfromance
Menz S - 20X10 - RPM 6200 OK Performance
Bolly 20X10 - RPM 7400 Great Performance
Mezlik - 20X10 RPM 6800 Less Performance than Bolly but better Performance than Menz S

I've got a Bambula 20X10 that I haven't mounted yet but I'll let you know the performance factor on that when I fly Patty with it.

Quick question to those of you using Moki 2.10's does the right thrust seem correct or should I put in another degree or two.
Thanks Mike,

I have a quick question also. Has anybody tried a Saito 180? I put one on mine and it is tailheavy as crap. Did you guys move the servos to the front or just add a bunch of weight?...Also what kind of performance did you get with the 180 and what prop are you using?...........Thanks......John

Thanks for the info with the Moki and prop combos. I am pretty content with the performance so far, but I have not tried much in the 3D arena with my setup yet. Vertical climbout seems limited, as in the plane is decelerating uphill rather than continuing to the moon. The book lists 7000-8500 on the ground and up to 10000 for max speed. I know that I'll never see that much with this size prop, but I think 7000 is a bit low. I will try reconstructing my fuel system for a bigger clunk and wider fuel tubing.

Thanks guys!

MRMcFarland:
Right thrust seems right on. I give very little rudder input during take off.

JRF:
I already have the Brisson muffler installed. When I first started breaking it in, I could not get it to richen any SLOWER than 6400. This leads me to suspect a restricted fuel flow, even with the Perry pump. I'm going to re-plumb the fuel system with a larger setup.

Thanks!

Jmulder:
check the reply #1491-1492 for my setup in this thread. I balanced 1/8" aft of posted CG at 15.8 lbs

232CAP Tain:

Thanks for the info and advise. I'm going to order a couple of props from different places. I like the Moki and Mejlik idea. I have been using the JZingers simple because I can get them at the LHS afer a prop strike and not having to wait for a shipment. Also, do you prefer the 10 pitch over the 8 pitch? I have been on 8 pitch with my OS 1.60's and they hold my 13 lb edge and 12 lb CAP in a hover at just over 1/2 throttle. I did pick up a 20X10 from LHS 2 days ago, maybe I should try that before I order.

Any thoughts?

could some body please tell me where you people are getting the aluminum standoff mounts for the BME 50 installation like shown on post number 36 a phone number where to get these would also be nice, thanks

When I ordered mine I asked the same question to Dave at DA. He said that he had a stock muffler that will exit like Sachs on the side, and he also has a bisson inverted pitts w/smoke. I opted for that. He also said that the bisson drops the rpm's by about 200-300. But if you wanted the rpm's back all you had to do was cut about 1/4" off the exhaust stacks. Hope this helps...:thumbup:

Thanks Monkeyhead. How many servos are you guys using and what size are they. I was thinking that if I could atleast get the rudder servos out of the tail that would be a big help....John

Engine standoff's.........

Just tell Roger what you want, He will help .

Anyone having any problems with the horizontal stab rocking back and forth. Mine moves between 1/16th and 1/32nd front to rear on both sides but not up and down. Is this something worh woring about and if it is any suggestions on a fix.

The zdz web site has stand offs

Edge,

Is this before or after gluing?

Many of the guys have glued pieces of balsa across the opening from left to right on both the top and bottom to give more gluing surface.

If the looseness is in the stab wing tubes make sure the screws are tight. beyond that it shouldn't be a problem.

I hope this helps,

Andy

Edge,
I've got 126 flights on my Patty and around flight 110 or so I had the same problem. I took some thin (about 1/32) dense foam tape and placed it between the removeable sections and the main sections. Then I used a nylon webbed picture framing clamp and placed it around the complete stab section to pull it together and tightened the screws. This has completed eliminated any play in the removeable section of the stab. I think this was caused by people using their legs, standing in front of the stab to hold the plane when I started it. Now, I will only allow someone to hold the plane by the wing and the fuse when it's started.

Thanks for the input guys. I to add support for more gluing surface for the "hard mounted area". The play comes from the removeable part of the stab. I think will try the thin dense foam trick. Thanks again.

Your photo shows the smaller 180/210 Bisson muffler. The high volume muffler has a larger can.

If you can't get it to richen up BELOW 6400, it sounds like your low speed adjustment is too lean. The low speed disk is very sensitive and it is sometimes a little difficult to get it right, but once it is, it will stay right for a long time.

If your low speed is too lean and you are compensating for it with the high speed needle, that could explain your problem.

I'd suggest you find an experienced MOKI tuner to help you set it up the first time.

Jim
