I put mine on elevator. I didn't even know it was "supposed" to go on throttle.

Thanks for the link!

Don... If they're put together like the old Futaba Flight checker it should work on any channel. The alarms/trackers are good insurance. I lost a 2-T in a rotor on the slope I used to fly in San Diego and never found the darn thing even after hours of searching. A beeper would have prevented that.

Thanks Jeff, kinda what I thought. I couldn't imagine losing my Oly for the lack of a $16 beeper. It would be my luck to be standing 20' away and never see my fallen angel.

Alright, I need your guy's help.

Is there anyway to set up a spoiler system without cutting into the wings?

I've got two wings I want to throw spoilers on, but I don't wanna hack them up... untill winter.

Are there any suitable alternatives?

Thanks!

I've never seen spoilers that are less than 1 rib bay.

I'd just do something like the multiplex? spoilers, the red plastic ones if you wanna be done in a hurry. Minimal rib cutting required.

Without cutting into them at all? No. The very, very simplest thing that could probably be done would be a flat spoiler. (Think of a thin piece of stiff plastic, with a "bead" along one long edge. Figure out a way to put wire pins in both ends of the bead, make someplace in the wings to receive the pins, for it to act as your hinge, and you have to have a servo or bellcrank installed in such a way that a cam will push the spoiler up, but the airflow will push it back down. It could actually lay on top of the wing (although would do terrible things to the airflow; it would be best if at least the bead leading edge was recessed). But you still have to mount the actuating mechanism and route either rods, pull cords or servo wires to it. If you have all that outside the airfoil, disrupting the airflow, you aren't going to need the spoilers anymore.

Figured that.

I'll just wait. They really don't need spoilers THAT bad. I'll just wait till flying season is over.

Thanks guys!

Hey Wylie,

You dog ... easy for you CA guys to say flying season is never over.

But PA ... the hi starts get pretty stiff and the white stuff fairly deep during Jan.


Here in Ft Wayne, I fly 12 months, but winter time flying amounts to just a few days during Jan if any.

I'm leaving for Muncie AMA LSF NATS within an hour to fly RES, here is today's Muncie weather forcast:


Today: Periods of rain. A few rumbles of thunder possible late. High 67F. Winds ESE at 10 to 15 mph. Chance of rain 90%. Rainfall possibly over one inch.


BTW, I have flown in Santa Rosa, LA and Torry Pines, CA is a great place for RC Sailplanes, wish I were there. Enjoy ...

Haha, and the winds and -10* temps don't help either .

I need some more help .

I did some harder hand launches on the Wanderer today. They went great (as in it didn't break ), and this thing just floats. There was 8-10mph wind. I know this might be partly because of the wind, but whenever I went to turn the tail dropped and it skidded sideways. I had to give lots of down elevator to get it to turn. I tried moving the CG up but only got it to just behind the spar. It still had this problem, but was slightly better. Should I move the CG up more? Could it be a dihedral problem? Even with the motor pod this thing was always a pain to turn, so I'm leaning twords the dihedral issue. I wanted to see what your guy's take on it would be.

Thanks!

Hmm.. I'm waiting to see the answers to this one, too. My first thought was that you're describing a vicious tip stall condition, but I'm not sure I get the tail dropping.

I went back out. Moved the CG to the spar. Dead air now. Turns great. I'm guessing it was a mixture of CG and the wind?

Regardless, I moved my receiver. I now have a perfect space for ballast. I know this is gonna need it. But it flew great. Off of a hand launch I got 30 seconds. I got to the point of where I could throw it, make a large circle around the field then catch it.

Now I just need my new hi-start to get here tomorrow.

Nightowl, hi there.
Night what did you end up doing with the OlyII wing, a while back now you were looking to do a three piece wing. Sorry if i've slipped up and not caught the latest on the build. I'm contemplating doing an electric O2 next year sometime so I'm getting O2 curious.

As a curiosity, I just realised TheNightowl gave me my first reply to my first post here at RCG in 2007, thanks mate. The 2.65m CMPro Discus lived a charmed life by slope and motorbike tow launch thermalling for 6 months before i sold her to a chap from the Sunshine Coast here in Qld. It still flies as of May this year at was the last i heard of it. My LHS has had one dusting on the shelf for the last 2 years.... I'm thinking of doing a deal with them to secure it for the future.

Hey Steve, how's it going?, I haven't been on this tread for a while. Have you mended well yet?
The CQ thermal champs are coming up on the 2nd weekend of september at Woodgate, I'd love to see you there if you can make it.
Catch up soon,
Dale
