Stevo Posted June 20, 2013 Share Posted June 20, 2013 Hi All, Flying a Blackhorse Ultimate, you can hear the ailerons flutter at high speed - and there is slop between top and bottom ailerons where they can vibrate. Anyone know of a decent system that can be assembled at the field, that does not result in any slop? Just saves me looking through the spares box and improvising!

Concorde Speedbird Posted June 20, 2013 Share Posted June 20, 2013 Click for larger image. Simply two horns connected with a clevis at one end. No slop, some say this method leads to different amounts of movement but it has worked perfectly on my Domino. CS Quote Link to comment Share on other sites More sharing options...
Stevo Posted June 20, 2013 Author Share Posted June 20, 2013 Interesting and simple CS - I though I said "farewell" to you in another thread! Nice to see you posting. Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted June 20, 2013 Share Posted June 20, 2013 The ARTF "Panic" uses carbon rods with ball joints on each end, the "cup" being fixed into the wings. This at half aileron span. This is a totally slop free perfectly aligned balanced movement easy swivelling joint system that snaps apart for transport if needed.

Dave Bran Posted June 20, 2013 Share Posted June 20, 2013 Correction, carbon TUBES with the ball joint thread sunk into and glued into the tube end !! Quote Link to comment Share on other sites More sharing options...

Steve Hargreaves - Moderator Posted June 20, 2013 Share Posted June 20, 2013 Yes we discussed biplane aileron linkages in CSBs Domino build just here...... I know CSB is happy with the twin horn connections but I just think the geometry is all wrong....maybe its just me.... Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted June 20, 2013 Share Posted June 20, 2013 CSB's uses the same method as my 1.20 Surpass powered Skybolt and I've not noticed any flutter on that - yet! The only difference is that for the larger, heavier 'Bolt I've used 2mm bore carbon tube sleeves for the connector. Quote Link to comment Share on other sites More sharing options...

CS i do the same as this with 2 servos in bottom wing so i have flaperons the only other way is 4 servos or have just top ailerons and bottom wing flaps Quote Link to comment Share on other sites More sharing options...
Stevo Posted June 21, 2013 Author Share Posted June 21, 2013 Thanks all! Sounds like the ball joint idea on the Panic is a good one.. I've a mini Panic on its way right now, so I'll lokk at those when they arrive. in appreciation Steve Quote Link to comment Share on other sites More sharing options...
Paul Adams Posted June 21, 2013 Share Posted June 21, 2013 I have one of the old panics and also a Pits Special. The Pits Special takes about 1/2 hour to rig by the time you have bolted on the wings, bolted in the inter struts (top and bottom), messed about with connecting the push rods between the top and bottom aileron, so it does not get flown very often. The panic however can be assembled within a few minutes, the top and bottom winds as secured in place with rubber bands, the inter struts use large press studs to clip in place (never lost one yet during flying, but if you mess the landing up they just pop off), and the aileron linkages just pop in. I have never heard / seen the Panics ailerons suffer from flutter, and I push it very hard. Quote Link to comment Share on other sites More sharing options...
001 Posted June 21, 2013 Share Posted June 21, 2013 The three Panics I had were fitted with flap on the top wing mixed with elevator. This gives very controllable slow flight and landings plus very square square loops and similar. If you don't want flaps, why not have another servo on a Y lead driving the top ailerons (if the aileron servo is in the bottom wing)?
