Trim.  My and I think Simon's ailerons had quite a bit of twist to them.



I was working on mine and noticed that as well. The outboard edges of my ailerons are twisted up. With a bit more on the left side than on the right.

Not sure if this can be corrected. Any thoughts from some of the more experienced builders? Or should I just be prepared for a bit of a wild ride on the maiden flight?

Additionally, I'm having a bugger of a time with the single aileron servo setup. lots of play in the linkages and fitting everything under that spacious canopy is a bit of a task as well. I'm debating just going with the dual aileron setup and move on from it.  Are there any hard and fast rules for where wing mounted servos should go? I'm thinking of putting them right on the CG line and about 1/3 of the way out from the fuse.

Takeoffs are optional. Landings are mandatory.

For the warped ailerons there is a chance that some washout was built into the wing/ailerons.  This would improve the slow speed stall but I doubt it will be an issue with the modern equipment.  I removed my warps after with a nice hot iron and holding the warped surface a little reflexed past where straight was and let it cool.  Takes a little time but the results are noticable.

As for the dual aileron locations you dont want them to far out as it makes the wings heavier in roll dampening and also the wing becomes thinner making for less room for the servos between the sheeting.  I installed mine and now Simons as shown and the result is rock solid and simple.  Yes there might be a little more drag but I would take that over the slop any day!
Yea 400W/lb should about do it.. But wouldn't a nice round 500 be better?

Thanks Ed.

Looks like I'll be needing some more sharp blades for my hobby knife.

Plus I noticed there wasn't a whole lot of "down" on the ailerons (or elevator for that matter). With a single servo that can't be good for the servo as it tries to drive the down aileron into the trailing edge of the wing. With two servos I can set some differential. As for the elevator, I suppose as long as I don't try to fly the course inverted. I should be ok.

You can put in differential with a single servo too  :)

finished!   Simon is cheating though!  he is 2g under the required weight!  Lets all hope the new spinners weight just that much more..   Nice looking planes if I dont say so myself. 

PS this is my 666th post.  Oh how I wish that number would stay there LOL!!

Thanks again Ed. 

I think mine definitely looks faster.  And I will make good use of those 2 grams! ;D

So I bit the bullet and went with the dual aileron setup as well. Was't too much trouble to install them. New linkages are in place and as Goldmember would say "they're toight, toight like a tiger"...toight like a tiger

Also glued in the motor mount. But I'd rather not revisit that particular barrel of fun right now.

I agree that the slop / drag trade for the dual aileron servos method is worth the work.  Possibly its easier that farting around with torque rods and that little space under the canopy!  Heck ive done Simons TWICE!  As for the firewall yes we all enjoyed that battle.  some how there has to be an easier way.  Oh and if you didnt struggle with it Robert we dont want to hear about it.

I belive there were 12 models where are the rest in the build?  Will any others be completed for the weekend?? 

Ready and waiting.

Well, I WAS going to tell you my technique, but not now.

I'll let you know how it goes when I get to my Nooner.  Right now it's in a plastic back, hangin' on the wall.

just waiting on some aileron linkages ... but with all this talk of dual aileron setups it makes me wonder if i should also use dual ailerons...

I want to cut a small air-intake in the 'chin' fuselage, about 8-10 mm wide and 2-3 mm tall.

Does anyone see a problem with this?

Yes it does, photo on page 2.

Thanks.

I'm going to circumcise mine too.  ;D

Almost ready to go... Only thing left is to install the elevator servo..

That looks like a fast one, Mike! Nice work.

It's Darth Nooner!
