[RCSE] Skeg Source?
I am looking for a skeg source. I have been using the tape on superskeg skegs but they are small and did not stop as good as others @ SWC and Fresno this year. I am also looking for some fellow (MRCC) club members as well. We need something for some Zenith nose cones and also some Soprano nose cones. Thanks, John D.

Re: [RCSE] Skeg - rod or blade?
For got Tom. You don't wont to be longer than an 1" from the end of the rod to the nose cone. If you go much over an inch you will start to see breakage especially in shortly cut grass where the rod is sticking into the grass roots or if there is a gravel base to the grass.

Re: [RCSE] Skeg - rod or blade?
Hi Tom I have used 1/4" carbon dowel from CST for the past 4 years. I would not suggest a carbon tube because it will not hold up to the forces that occur during spot landing. You can see my installation on my Escape Lt. at http://www.rcgroups.com/forums/showthread.php?p=3174690#post3174690 Go about half way down the page. If you have any questions that I can help answer please let me know and thank you for all the help you've been in the past.

I would be afraid of breaking one. That could cost you your landing points at Nats by shedding parts on landing.

Try it, other than looking like a TD plane with a drippy nose/head cold, it might work just fine. ;-) Bill RCSE-List facilities provided by Model Airplane News.

[RCSE] skeg, er Servo question
Hi all, Has anyone ever used the non-digital Hitec wing servo (HS-125?)? I'm looking for a thin, reasonably priced servo, and that looked like a good compromise - any neqatives, positives, suggestions? This is for a 1/3 scale ship, aerotow, thermal flying only - for outboard aileron ( on a 3 surface wing). The inboard aileron will probably be controlled by a medium to standard sized BB servo, the flaps: a 225-MG or larger. Thanks,Brent

[RCSE] Skeg Story
Last year I decided to take in a contest in Florida..Iva and I need some warm weather..I called the CD and ask if skegs were allowed..All he said was "I think any one who needs a skeg to land needs more practice." I should have ask a more blunt question..So being the cooperative person that I try to be, I cut off a permanently mounted skeg..When I got to the event "EVERYONE" had a skeg but the C/D and me... I like them mostly for flap protection, but I have no problem complying with the call of the C/D for that event...Brian Smith RCSE-List facilities provided by Model Airplane News.

[RCSE] Skeg Flap
Dana - I hope that you are right. Unfortunately, I am not at all sure that it would work out this way. I have seen things like this go wrong too many times. The CD might forget to act in time (I can certainly see myself messing this up). Folks can legitimately argue that "if it's in the rules, we should abide by it, especially at the Nats." I know of several who will make this argument. They can escalate past the CD and Event Director, and the AMA Staff will back the rulebook every time. I am lobbying to kill this rule before it gets any further. I hope that you will join me. I think it's easier to get it now than have to live with it later. happy trails - Rob Glover Rob, When we were putting the CD rule changes together for last year (particularly the landing task), we took a little bit of a verbal beating. The final arbiter of whether or not a change would be accepted (no matter how much people agreed or disagreed with it) was whether or not people knew early enough to practice with the rule change. I think changes are possible at the NATS, as long as there is sufficient lead time for people to adjust. Knowing the people who have been in leadership of the NATS in the past, I would suspect that this rule, even if it passed, would be quickly overruled/changed by the affected CD and the powers that be, early enough that it would not affect the NATS. Wish I could be there. just my 2 cents. Dana Flemming 2002 Nats Event Director > RCSE-List facilities provided by Model Airplane News.

[RCSE] Skeg Rules for RES Sailplanes
Title: Skeg Rules for RES Sailplanes A point that has been overlooked in the skeg rule discussion for rudder/elevator/spoiler airplanes is that if skegs are outlawed, designers will find a way around the rule. The optimum duration sailplane fuselage might feature a drooped forward fuselage that aligns with the upwash flow into the wing. The aft fuselage might also droop to align with the downwash. These angles are on the order of several degrees at thermalling speeds. There is a serious landing problem with the drooped nose. If the model lands straight and just a little hot it tends to bounce back up. If it lands a little hot in a crosswind, the yaw moment imparted by the ground on the nose both bounces the airplane and yaws it at the same time. If the model has ample dihedral, this action can result in a rapid and uncontrollable roll followed by an immediate inverted collision with the ground. Hobie Hawks are well known for this behavior. The drooped nose is a problem even for the most perfect landing. When the model is sliding on the ground the wing is at an angle that produces substantial lift. This reduces the friction with the ground and the model slides a long way. This is like putting on a fast green accuracy is reduced. One solution is to mount a skeg behind the center of gravity. Touching down on the skeg pitches the airplane down, reducing lift, increasing friction and shortening the skid. It also tends to straighten the model out in a crosswind landing, a possible advantage. In any case, the Hobie Hawk flip is eliminated. A skeg would be an excellent improvement to the Hobie Hawk. Another solution is to reshape the fuselage so that it has a deep belly that bottoms out aft of the CG. If this belly starts from a high nose, the model is able to touch down aft of the CG and pitch down. This can have essentially the same function as the skeg. Mark Smith did this with his popular and successful "Windfree" design from the mid-1970¹s. Shaping this belly so that it is aerodynamically clean is a challenge for the designer. Shaping it so that it is aesthetically pleasing is a greater challenge! Outlawing this shaping may be challenging for the rules-makers, but as long as great emphasis is placed on landing scores, the designers will find a way. Lastly, a simple solution is to mount the wing at a lower incidence angle on the fuselage. This causes the fuselage to touch down on the aft fuselage or tail, and reduces the lift during the skid. Of course, the model will thermal with the fuselage pointing nose-up. This is not too pretty, in my estimation. For my money, the skeg is the most effective, aesthetic and aerodynamic solution to the problem. It also protects the bottom of the fuselage on hard or abrasive fields. I suggest permitting the best solution to the problem as opposed to forcing a second-best solution on the competitors. Blaine Beron-Rawdon 1/27/00
