Don't worry about a caller, go to the contest of your liking, let the CD know that you don't have a caller, ask if he can introduce you to someone that will call for you during the contest. I'm sure he'd be glad to hook you up. Hope this helps, Dan.

RE: Extra airfoil thickness
The thinner airfoils on the tip are done by design. These help the plane to start and stop rolls and snaps more crisply. Other models (extras, edges, yaks, etc.) have the same.

RE: aileron throws
Mr. Hanson: Your post is very accurate. BsSmith's post #4 does not mention any bias influences other than vanilla landing. I assumed he just lined up with the threshold and flared. IE slipping the plane in was not mentioned by BsSmith when the tip stall happened. It always a great read to take in your post and give them thought. We share a common interest. My thoughts on tip stalling in a crab do not involved one wing flying faster than the other. One wing flys faster only for a second when the rudder is applied, and the forward wing moves into position. If the plane does not tip stall at that point, you have enough airspeed over both wings to survive that rudder input at such a slow speed. If your plane tip stalls after that the wing in the rear postion stalled due to two (2) factors: 1. The leading edge of the rear wing is more swept than the forward wing (depending on design). Most Extra's, Yak's, Caps, etc have 5 degrees of sweep per wing. In a crab the forward wing becomes a straight leading edge wing, while the rearward wing goes to 10 degrees sweep. Assuming a 5 degree crab. 2. Part of the rearward wing (inboard part) is hidden by the fuse as seen by the flight path. That makes for less squares lifting on the rearward wing. Put 1 and 2 together and we get stall of the rearward wing at slow speeds. Both wings are traveling through the air at the same speed once the crab is established since both are attached to the same fuse. Just my thinking on this, I do love to read and take in Mr. Hanson's post on these "flight" questions.

RE: aileron throws
If it's tip stalling, you have an incidence issue with one wing tip. IE a warped wing. Tip stall is just that, tip stall. Not tips stall. One tip is stalling before the other one does causing one wing to drop suddenly. This is caused by the leading edge of one wing being at a higher angle of attack than the other. Put an incidence meter on the tips and be sure they are reading the same. If they read the same, then one wing is heavier than the other. Hope this helps,

RE: Carden 37.5% Yak Build
Here's my cowl former (or like). This type of cowl is "front" heavy. The brace shown really does help with all the cowl shaking caused by idling engine. There is ZERO slope and ZERO play in the cowl now. It's as if it were connected to the fuse solid. Two of the screws on each side of the cowl (same screws that hold the halves together) go into the stiffner. From the outside it is completely hidden that it's there.

RE: roll coupling on knife edge - problem
Tall fin and rudder is scale on the Edge, the full scale has a very tall fin and rudder also. The competition pilots are using a mix to fix that problem. We will have a different value for right top rudder than left top rudder. Putting negative dihedral will make that plane look odd, and create other bad flight habbits in other flight attitudes. Dan,

RE: Are aircraft themselves judged in IMAC events?
Since we are on the subject, I can't think of any stock built aerobatic planes (arfs or kits) that would not be allowed to fly. I know there are a few out there that exceed the 10% rule by just a "pinch", but would fly in a contest without causing concerning. Excuding pattern planes that look somewhat like Extras, what are your thoughts Mr. Bubba and Mr. Silent.?

RE: Discussion - Scale aerodynamic characteristics
First things first, be sure your model is 1/3 scale in weight for the test. Not total weight either. Scale weight wings, scale weight rudder, etc. You'll have to cube the weight down to your size.

RE: Span-to-length ratio: Question for Rocco
Dan: Some of the Aero-works planes are flown in competitions. IMAC has a 10% rule where as the model must be within 10% of the full scale plane. This limits what designers can do with the span vs. length and still be legal to fly in IMAC, Invitational, freestyle type events. Hope this helps. Dan Baker.

RE: Two different airfoils on a bi-plane??
The model is done this way due to the full scale being done this way also. On the Ultimate 20-300 (full scale) the top wing is thicker than the bottom wing so the top wing will stall last on landings and spin entries. This will keep the entire plane from lossing attitude in the roll axis upon stall. I.E. turning your bipe into a high-wing trainer at the most critical moment. See pic, you can clearly see the thicker (different) airfoil on the top wing. The plane shown is the trainer version of the Ultimate 20-300.

RE: 2009 Basic Narrative
Flimsy is slang for a call sheet that has been laminated so it can get wet, be laid on the ground, fuel get poured on it, etc. Some take the aresti and laminated it also. Anything laminated that is used as a call sheet.

RE: Nose lenght?
Nose lenght in sport planes (full scale), warbirds (full scale) and all others (full scale) was determined by whatever the engine weight was to balance the plane. That's why most warbirds have such a short nose, very heavy engines in those days on the full scale version.

RE: 2009 Basic Narrative
Most all pilots are also callers for their fellow' pilot. One thing I have learned when I went to "calling" the manuever straight from the aresti sheet is: Now there's time for me to look up and help coach my pilot through the maneuver. As an example, my pilot may not see that his humpty is falling off track since his eyes and his plane are so high up and all he sees is blue sky. I can now tell him, " right rudder over the top", and my pilot will do it, trusting me that I've looked down at the treeline or the runway and determined that he's tracking off. If we are reading text from a written sheet the caller will have not have the same amount of time to give "in the manuever" coaching. I used to call off a sheet of text, switch to calling off the aresti a few years ago. Will never go back. I will say, that when I started out, I called off written text though.

RE: 2009 Basic Narrative
There won't be time in the contest flight to "call" any scoring criteria such as, "be sure to center this half roll on the downline". Your pilot will be in the ground before you "call" that statement and then call for him to push or pull to exit. There are judging schools going on all over the country over the next two months or so. Check out the IMAC site and you'll see one near you. Have all your guys that you are helping there. Actually it's the pilot that needs to know aresti as well as the coach. The pilot needs to have the scoring criteria in his head as he's flying. This way the "call'' can be shorthand words like in the previous post. Judging Schools will teach your guys more than you or I can teach them in two months of flying every weekend.
