No good deeds go unpunished.
About the flaps, I dont know what you have for deflection, but very often I see much more flap applied than is needed or safe. Every plane will be different. Maybe just 20 degrees or so is all thats required.? +-

The other issue you may be up against is the large prop, which equals large amounts of P-factor. This will certainly show up on takeoff and when you are slow and add power.
Just a few things that may help get you going in the right direction. Thanks for being so honest and forthright with your experience. Most guys would not have the guts to report when things go bad, especially if it was their fault.
Kudos to you.

Len,

Thanks for the kind words and the tips. It helps soften the blow of todays flight. I will take them into account on the next outing.

The flaps were set full at approximately 80 degrees at the time of the stall and I just wasn't used to a plane that had that much flap. I wanted to see what kind of response I would get with that much flap and well....I guess I found out.

At 45 degrees she came in smooth and still under control before the mishap. The 19x12 prop was pulling at half throttle approximately 25 to 30 amps and at that setting she was flying level and smooth. So I think I'll stay with that prop/battery combo for the time being since it seems to perform very well.


Employ your time in improving yourself by other men's writings, so that you shall gain easily what others have labored hard for.

Hey Rudderman, sorry to hear about the mishap. Flaps can be a challenge with certain planes but that's what makes this hobby so much fun. I have a Pawnee with flaps and have to remember to keep some power while landing or it will drop like a rock. Keep it going. I am still going to get one of these.

Got quiet here. So what's the verdict? Would you recommend this plane?

Hi Harry,

Sorry for being absent from this thread but the weather here and work has kept me from taking her up again for more shakedown flights.

I would recommend it. It's a great plane and when I'm not crashing it, it flies good. Took a bit of tweaking for eflight but I'm confident I have ironed it out.

Apart from the minor little problems, it is a well put together plane IMO.

I like it.

I had the chance to fly the review plane this weekend. All in all its a pretty nice flying plane. We towed a little Cularis for fun. The plane looks good in the air and on the ground. I did find an issue with the plane when landing. You need to keep the speed up on your turn to final or the wing will drop. This happens on my big one too, it must be due to the narrow wing cord. Also, when in ground effect, land the plane. If you try to drag it out and get it too slow, it will drop a wing also. I think setting the flap to about 15 degrees will help a lot.

This is a real nice plane for the money, no harder to fly than an intermediate style plane.
I would recommend beefing up the ply landing gear plate right from the start.

Here are some pictures

Thanks Perry. I was waiting around to hear a little more before I pulled the trigger. Bang Really glad you like the Wilga. I am so busy with work and it's frustrating as we have excellent weather. Have to drive up north tomorrow and threw a plane in the truck just in a case.

Good report Perry and Len ! The weather and timing for my days off are just wrong down here. If it isnt raining it's too windy. I'll get it out eventually but our club field is a problem too. The weeds have taken over on our runway and with the drout and heat we had last year it's really taken a toll on our field.

From what we've heard about the flight reports, I've sealed all the flight surfaces on mine and will add VG's to the wings in front of the ailerons. Hopefully that'll help with the tip stall problem. Perhaps deviating from scale a little and adding a few more rib bays would probably turn this one into a nice flying plane.

Yes, 26cc will fly the plane. The plane is very light overall.

Would really like to know about any experiences you've had with VG's on RC models.

Hooverup,
There's some intresting results on this thread -
http://www.flyinggiants.com/forums/s...ad.php?t=69690

I'm still waiting to test fly this Wilga before installing them. If I do I'll probably remove the slats.


Also start at post 157 here...
