Kangke Waco Biplane

RE: Kangke Waco Biplane
did everyone use 4 aileron servos or just 2, I was planning on using 4, I'm almost done except for the electronics and motor. I used black pin striping along the border of the red and silver, It really made it look nice. Another thing that puzeled me was they said don't remove and covering form the fin or stabilizer when epoxying them. Thats the first arf I'veput together that said that. I wonder why?

I want to replace the aluminum tubes with brass or copper lines so I can solder the small barbs on the ends to keep the fuel lines from coming off, I didn't have any luck trying to solder the aluminum lines. I'm new with gas, but I've read the fuel lines expand with age and can come off the lines. Has anyone tried a 3 blade prop for clearance?

You cannot solder aluminum, so brass is a must.
For my YS engines, after I bend the tubes to shape, remove it from the stopper so it does not get damaged. I solder two wraps of thin #24 gauge wire about 1/16" back from the edge with very small torch using standard electrical solder and paste flux, NOT the acid flux that comes with silver solder!
A little WD40 helps get the brass tubes though the stopper and after the lines are connected, I wrap the same wire around the fuel line twice then give it a few twists to hold the fuel line on.
Never had one blow off with the YS engines.
A large 100 watt soldering gun would probably work too.

Mate, just flare the ends of these fuel tubes slightly with needlenose pliers or similar. No soldering needed

What has everyone done that has used 8 servos done as far as plugging them into the RX? Is 8 to much for the rx or do you need a power bus for the current draw?

Not for this plane. It's not that big and heavy that it justifies power distribution

the weight of the ZDZ40 is almost the same as the DLE55, HP is 5.5 for the dle and 4.8 for the zdz. Would a DLE55 be too much?
ZDZ40
Wt - 3.25 Lbs
Disp - 40 CC
Power - 4.8 hp
Prop - 20X8, 20X10
Static thrust - 22 lbs
DLE55
-
5.5 HP at 7,500 RPM
Weight: Engine, 2.9lbs (1310g)
Muffler, 3.5oz (100g)
Ignition, 3.9oz (110g)

Yes, a 55cc would be an overkill for this plane
From memory, the prototype plane was flown on the ZDZ40 and the manual states it was at the top end of the power range

Maybe the best choice is to simply wait till the engine you want gets in stock somewhere?

you will have to cut a hole in the firewall so the carburator can fit behind the firewall so you have the proper clearance for the prop and cowl. I dont think you will for the dle 35. troy models handles the zdz engines and parts . A picture somewhere on this forum shows a dle 30 mounted and they did not cut into the firewall The dle35 is a rear exhaust but I done think it is any different as far as spacing the muffler fits under the carb and the standoff holes are wider for the muffler to clear. The ignition is rated for 7.5 volts which is nice can run a lifepo or lithium ion or run the ignition cutoff.

Buy one!
Its worth it. I have several and use them all when setting up a plane before final gluing.

But does 1/4" equal 1 degree?
I have used levels in the past as well just to check that things were at zero but I don't think there much good for any more then that.
belong to a club? if so, someone must have one you can borrow.
Harbor Freight also has a nice digital gauge one that can be used with RC with a little thought.

That’s a good question, I slept through as much of geometry as I could. I know there must be a formula here somewhere. I remember many moons ago we used protractor gauges with rockets to get the altitude. I’ll ask at the field next time and see if anyone has a incedense gauge. I’m still waiting on the motor and servos to arrive from tower. Once I get that in hopefully I can balance it with the rx, regulator and battery placement.

All done with the Waco except for setting the Incidense which I'll do tonight so I might fly it sunday. I ended up with a OS gt33 for a motor. Didn't have to cut the firewall and it fit nice. I had to mount the cowl as far forward as I could. Where's a good place to start as far as the incidense. I want it to fly easy to start. Should I set it at 0 or +1

What do you use for the datum line in setting the incedence, level the horizontal stab?

I have mine set at 0 degrees and it is quite good
