[RCSE] Spoilers and Crow program for Jr 8103?
I would like to be able to run a crow configuration from the left stick and raise the spoilers part or all the way using the three way switch on my JR XP8103. How should I proceed?

Re: [RCSE] Spoilers-Elevator
>Computer mixing should not be required for properly designed spoilers. This is an artificial requirement. One could just as well argue that elevator mixing should not be required for "properly designed" flaps, since this just might allow you to use a somewhat simpler radio. It could be done... just move the landing flaps sufficiently outboard. For RES I always use one very big center spoiler, and mix in whatever amount of elevator is needed to minimize the change in pitch trim. The mixing is really a convenience, and could be skipped if manual elevator compensation is used. On landing you're always closely controlling the elevator anyway, so the manual mixing is hardly onerous. There are many advantages to having only one center spoiler: * There is only one spoiler to build and set up, not two. * Only one wing servo is needed. * It's near the CG, so it doesn't add yaw inertia (a handling-killer for r/e). * Outer wings are clean so there's no degradation of roll control on landing. - Mark RCSE-List facilities provided by Model Airplane News.

I have never used elevator coupling on any thing but models with flaps. When spoilers are extended at normal speeds, the model should drop the nose slightly to maintain air speed while increasing the rate of descent. If your model doesn't do this then it has a design deficiency. Chuck Anderson RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]

Should spoilers be computer-mixed with some up elevator, or do most guys flying RES, add up- elevator manually on landing approach? What setup is used by most RES pilots?

The Victory RES is 121" (3M) and I'm >concerned that the 15" spoilers are going to make it drop like a rock when >deployed. > I would install the spoiles as is. My 132 inch span Sirius II had 1 inch wide 14.5 inch long spoilers and they were definitely too small to control airspeed when landing. I had to add 4 inches to the length to get enough drag to control airspeed on landing. Just remember that spoilers can be used just like a throttle on a power model if controlled by the throttle stick. Don't extend them fully unless you need the drag. If altitude is not a problem, I normally extend half spoilers on base leg. That way, I can retract the spoilers if low or need more speed or extend them fully if I need to loose altitude or slow down. I hook the spoilers up just like the throttle on a power model; push the throttle forward for high speed and pull it back to slow down.

Re: [RCSE] spoilers in an olmpic 2
The spoilers shown on the Oly II plans are quite adequate. Since we now have small servos and computer radios I would activate the spoilers with servos. One servo in the fuselage and string, tubing etc. works well if you want to go that way--a little more trouble rigging is all. Mike Clancy RCSE-List facilities provided by Model Airplane News.

With servo in fuselage, spoilers activated by strings as shown on plans. Spoilers seldom closed properly, and a hassle to hook up at the field. Very inexpensive 2. Servo in fuselage. Spoilers hooked up with Very Flexible Sullivan control cables. Works very well, spoilers open and close in a very positive manner. Still a hassle to hookup at the field. Slightly more expensive, but much better than option 1 (above). 3. Hitec HS80 in each wing. Hooked directly to Servo. Y harness to hook to throttle (spoiler) channel on four channel receiver. Works best, Easy hookup at field. Most expensive. Hope this helps.

Re: [RCSE] Spoilers
Dave, I just bought a set of each size from my friendly Multiplex dealer (www.polecataero.com) and they look very well made. They are all aluminum with plastic connector arms, and are actuated by a servo which pulls on an arm inside the spoiler. The servo can be mounted at most any place and uses a cable to activate the spoilers The weights are as follows: 250mm long set weighs (for both sides) 2.44 ounces (for 2.6 to 3.6 M span) 370mm long set weighs (for both sides) 3.58 ounces (for 3.2 to 4.6 M span) Well worth the price, very classy. They have a lock when closed, to prevent them from deploying on launch.Bill Grenoble RCSE-List facilities provided by Model Airplane News.

Does anyone have any comments on the Multiplex 'contest spoilers'? What do they weigh? How are they activated? What is the justification for the cost ? Dave RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]

I think you'd better go back and study basic aerodynamics and maybe start with one of the soaring manuals for student pilots, because what you've said here is very misleading to someone who doesn't know better or is just starting out in this hobby Keith M RCSE-List facilities provided by Model Airplane News.

I have also seen a Sailaire strip the gears in one of the small servo's when it was allowed to get into a vertical dive. Always use the largest and strongest servos you can.

[RCSE] spoilers
I have a question about sailplane design and hope this is the correct forum. With all the discussion of politics and personalities, one can never be sure. ;-) This discussion is focused on open class, large sailplanes. If I understand it correctly, dropping flaps results in increased lift and increased drag. So when the flaps are down, the plane slows down but has relatively high lift for the speed. Then if the flaps are raised, the drag goes away, but so does the lift and the plane drops out of the air. Hopefully this happens a few inches above the ground immediately over a landing line. Given the same plane cruising in, if one were to raise spoilers instead of dropping flaps, the plane slows down and lift is destroyed. The plane slows down and starts to descend. If at that point the spoilers are retracted the plane is going slow, but the lift is increased relative to the spoiler deployed setting. It seems that you could maintain a higher degree of control using spoilers instead of flaps for a final and not risk striping gears on flap servos. Is this true? Bottom-line question. With modern radios and the availability of lots of channels and light weight servos, why don't more open class planes use spoilers as an option for speed control Just curious. Thanks for all opinions and discussions. Bill -- The one good thing about repeating your mistakes is that you know when to cringe.
