Tail areas

Hi guys,

Has anyone increased the areas of the elevators and/or rudder ?

If so by how much ?

What travel are you using for each control surfaces ?

The manual shows the factory settings where to connect the clevisses but my Radian pro had a couple of different positions out of the box.

Thanks for any information.

Zor

I also have an ALES switch thingy installed and programmed so it automagically cuts the motor at 100 or 150 meters (depending on the conditions), which simulates a small hi-start launch pretty well. I generally don't use the throttle for anything but launch and the occasional electric thermal, so having it on the throttle stick was just a waste of a good control for me.*

One thing though, don't try the launch trajectory of those super slick overpowered ALES birds, the RP is needs a little chance to build up airspeed before she can climb away, but it'll still get to altitude fast enough. I usually try to keep her nearly level for a second or two, and then she'll start climbing out on her own, and you maintain a good airspeed in climb with the elevator (again, just like a small hi-start.)

Also, forget the high energy spot landings (you know what I mean ), that's where the expensive parts are!

*Typical caveats apply (Your mileage may vary, don't try this at home, professional driver on a closed course, not to be used in hospitals, etc.) Enjoy!
Good info, thanks, Jimmitude. I have never been a big fan of "high energy spot landings", anyway. One question: what is ALES, other than really special beer?

Cool pics EC. The flaps down pics are my favorite. The lights reflect off the flaps...way cool!

I got my lights and new batteries, switch, etc in the mail this week. Will be working on them this weekend if the chores don't overwhelm. (it's been so wet here that the lawn needs mowing twice a week! Last year was a drought.)

Hi, Moose.

ALES is a competition format called Altitude Limited Electric Soaring. One is allowed 30 seconds or 200 meters, whichever comes first, with the motor on and then it becomes a 10 minute duration event.

A very small flap deflection (just a couple of millimeters and not enough to see in a picture) is used to increase lift in some conditions and is called "camber". Pilots use camber on both the flaps and ailerons to eke out a little more lift.

The main use of flaps is to get it to come down, and they are very effective. They lower the stall speed and increase the drag. They literally drag the plane out of the sky, and are great for landing in small fields or doing spot-landings in competitions.

Yes flaps make a huge difference. Usually if it's windy I use 45 down with or with out crow.
Sometimes I don't bother as the wind well kill your airspeed

But when it's calm, full flaps at nearly 80 degrees down is awesome. Sometimes I throw crow in there for a little jazz

Thanks jumpy, the lights are awesome and adds a whole new feeling when flying. The pic your talking about is now my new desktop screen shot

I was thinking about adding the switch I got to.
I just need to make a adaptor to go between my esc and battery so I can run the switch from that instead of chopping up my esc wires

But I forgot all my channels are used on the orangeRX

To some extent it depends on you and your radio set-up. On my full house gliders (R/E/A/Flaps) I use the flaps throughout the flight as part of my camber and reflex mixes. Then I use them during landing to help me hit a very precise landing zone.

On my radio I can also set them to follow the ailerons to give me more roll authority. I have this mix on a switch so I can turn it on and off.

Very useful devices, flaps.

I don't have enough mixes on my DX6i to make the flaps follow the ailerons, but I am curious...when do you use it? What type of conditions make this increased roll control necessary? One example I can think of is when coming in for a landing and the winds are gusting all over the place. I am guessing the extra roll control would help you keep the wings parallel to the ground.
