Kyosho DC-3 Help!

Before you go to that much trouble, check the wings. Mine had 4 degrees of wash-in in one wing and 2 degrees of wash-in in the other. Even though I raised the ailerons to compensate, it was a tip stalling fool. The other problem with that plane is it's tendency to jump straight up on take-off. Oh yeah, it is also 1 1/2 pounds heavier than the advertised weight.
I knew of four or five that did not survive their first flight. I had two flights before I sold it cheap to a guy who promised not to try and fly it.

I have the unbuilt Kyosha 3. The quality of work on the tail are pretty bad, it would be very easy to duplicate. I can fax the outline of what you need if that would help. Rigging the alierons up will not help they are not the primary source of lift, about the first 15% of the leading edge are. You have to wash out the wing or twist it, leading edge down, trailing edge up. The real 3 tips stalls worse than any airplane i"ve flown, the good news is that it stalls at about 55 knots. Bob Metz

I test flew one of these for a friend some yrs ago and what
people are saying about the tip stalls are very true. Also
any attempt to use the rudder while flying usually resulted
in a spin, no matter how little throw was used. All in all,
it was a very nasty handling aircraft. It was a relief to
my friend when he finally lost an engine and it spun it to
it's demise.
Can't say these traits carried thru for all
the kyosho DC3's but I suspect so.

robert waldo thanks for the offer. I don't have access to a fax machine during the day. My fax number at work is 480-891-8587 but use it only at night. If you scan it and email it that would help. Is the Top Fliter DC-3 same size? I also trying to track down a set of Top Flite DC-3 plans and rib sets. I have the part numbers from their web site. So far no luck though. I have motors, ESCs and batteries. So thanks for all the info and advise.

Yes I have this model and would be glad to trace or scan the parts you mention.
How may I get them to you?
What I do not have is the main instruction manual. Can you help me?

Hi!
Before you go to any more length in building the Kyosho DC-3 ....check the wings for wash-out...or wash-in...which is disastrous!
It is rumored that Kyosho discontinued these ships because the wings were wrongly cut/built!
I have seen two of these airplane start...not one leaving ground...they all "snapped"at the moment leaving ground.
If the wings are built with wash-in, which is no good ...this could be fixed with a little labour!
Check them out before you do anything else.
Regards!

Is there a GOOD way to determine the washout/washin on these pre built wings. If there is a problem I would like to correct it.
I would think that at the worst I would need to remove the covering, set in the correct twist, and recover the wings as they are held in position. I like a good challange.
If worse comes to worse It will make a great static display to hang from the ceiling of my home office, so I will still be looking for the assembly instructions just for the practice.

Well you can mount the wing to the fuse and then block up the fuse to a
level/0 degree position. Then starting at the wing root closest to the fuse
side check the incidence with a meter moving out to the tip.
Should give you some idea of what you have.
Not sure of how clear I am here but I know what I mean

The wings are fully sheeted with balsa. You will need to strip the covering, slit the sheeting, twist the wing, block it in position, reglue, sand and recover. I did it. Thats when I discovered that the Kyosho DC-3 also has a problem woth the wing blanking the stab at certain angles of attack. Like on take-off.
You know, when all these separate people tell you that the thing is unflyable, they are probably right.

I still would like to find the assembly instructions if any one can help.

I have had 2 of these kits.
I crashed the first one and sold the other.
All the other guys are DEAD ON this plane has some issues.
I would paint yours up all pink and try to sell it to Hooters for a hundred dollars.
I wish that is what I did .
This plane is like a woman with bad credit....
costs a lot to get into and in the end it just is not worth it.

I believe that if 10 men tell you you are drunk you better sit down.
Likewise with trying to fly this model.
I would still like to get the assembly instructions if anyone has a copy.
As I said earlier I am going to use it for a static display to hang from my ceiling.[&o]

Did you have anyluck finding the manual, I need one also.
I may be a fool, but I have all the necessary stuff to get the bird flying and I bought one new in the box for only $75.00.
So if it does crash, which it probably will, I will make sure to make it really spectacular...

Hey,
I just found the manual for the DC 3 in the bottom of the box, in a day or so, I will scan them and email them to you if you will give me your email address.

HI!
It should not be that much work getting this DC-3 fixed!
The problem with the wash-in in the wings are rather easy to fix.
As they are foam wings they have to be cut lenght wise so that it is possible to twist each wing so that you get wash-out instead of wash-in.
Take a sharp bread knife or Japanese fine toothed saw and start to cut / saw the wing from the inner part to the tip .
I would choose to remove the plastic covering before I do this.
When you have made 3-5 long cuts 3-5cm apart you will feel how flimsy the wing is..or should I say how easily it is to twist the wing.
Now you have to fill the cuts with white glue or Aliphatic resin...or epoxy covering resin.
Use tape to hold the wing in shape and see too that you get the wing twisted in the right direction (some wash-out).
Doing this right is going to make the Kyosho DC-3 fly OK...I hope.
Build it light and I'm certain that this airplane will fly just fine
Here is my scale 3-blade 10x5 carbon prop for my Marutaka DC-3 (span 211cm). Engine is OS FS .26. This engine turns this prop at 9200-9500rpm on 5% nitro and 15% Motul "Micro" all synthetic oil.

The flying issues are true. However they are pretty on the ground and in the air. Mine was hurt on take off when a gust blew her in the air before I had enough ground speed. Damage from the resulting cartwheel was minimal. Because of the flight problems, I'm not sure I'll ever finish the repair to flight ready.
