Flyer Posted February 9, 2016 Share Posted February 9, 2016 I reversed the elevons on a delta; launched and it completed a full roll before dropping it into the long grass, unscathed. I make certain these days I waggle the bits in the right direction!!! Quote Link to comment Share on other sites More sharing options...
rcaddict Posted February 9, 2016 Share Posted February 9, 2016 yes we all wiggle the throws just before flight but how many actually stop to think about the direction of ailerons Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 9, 2016 Share Posted February 9, 2016 I've done it on a test fly with my own model, and yes I did stand and do a pre flight check, sometimes the brains otherwise engaged and it don't register.

Martin Harris - Moderator Posted February 9, 2016 Share Posted February 9, 2016 A favourite is changing a servo - and not realising it works the opposite way. Hitec seem to rotate opposite to Futaba for example. I once stood next to a 1/12 scale pilot (well, normal sized pilot of a 1/12 scale combat model) who immediately after hand launching exclaimed (in words probably unacceptable to this forum) that there appeared to be something awry...then said words along the lines of, "whoops, wrong model" - and proceeded to reprogram his transmitter as he flew...with reversed ailerons AND elevators while avoiding the attentions of other models chasing his tail streamer! ...and yes, of course I was one of them I did once get away with reversed ailerons but it was on the maiden of someone's Nova trainer which had a lot of dihedral and quite low rate ailerons - after some mental head scratching and adding lots of rudder when "turbulence induced wing dips" failed to respond to aileron, it dawned on me that the ailerons were reversed and I just left the ailerons alone (most of the time...and recovery was fraught and very nearly terminal) while I negotiated the circuit on rudder. The cause - an eager volunteer rushed to carry the model onto the strip after the range check, I didn't call him back and I missed my customary control check before taxying out...but my fault entirely.

fly boy3 Posted February 9, 2016 Share Posted February 9, 2016 Hi Geoff, hope you do find out what happened to reverse the ailerons, I,m on edge LoL. Cheers Quote Link to comment Share on other sites More sharing options...

That's what killed Roy Chadwick, designer of the Lancaster. I wonder how many similar accidents have happened. I thought the Tudor went into an unrecoverable stall. **LINK** Bottom of first page.

Nigel Grant 1 Posted February 10, 2016 Share Posted February 10, 2016 I had a luckier escape when I retro fitted a servo for nose wheel steering to try and improve ground handling on take-off. The fit out went OK and even the programming to take the most of the 5 point curve and setting a switch. It all looked good, the nose wheel responded nicely. But I was focussed on the nose wheel and never watched the rudder direction. My first attempt at a take off run was bit confusing, especially when rudder input against the torque effect just made it worse. After a second attempt standing behind the model, it dawned on me what the problem was. No damage as the plane hadn't built up speed to tip over. Quick servo reverse for the nose wheel and I was in business and my take-offs were much better than they had been. Quote Link to comment Share on other sites More sharing options...
Braddock, VC Posted February 10, 2016 Share Posted February 10, 2016 Geoff, I always attribute such anomalies as age related ie reverse experience. It makes me feel better anyhow. I damaged one model to the cause but my most painful ones related to forgetting to extend the aerial which I've done on several occasions but never since I went 2.4.

Braddock, VC Posted February 10, 2016 Share Posted February 10, 2016 Posted by Geoff Sleath on 09/02/2016 21:34:20: In my case I was on the right model so model match wouldn't have helped. In addition to my little faux pas at the field my Taranis navigate buttons did the sadly all too common trick of disappearing into the case (it happened on my other Taranis). Then, to add insult to injury, I broke the fragile plastic as I was gently (as I thought) cleaning it with Ultraclens before glueing it back in place. Still T9 (hopefully) have come up trumps and some new buttons should arrive tomorrow. Well I never! the taranis does have warts after all. And there's me led to believe it was as perfect as Kylie's derriere. Quote Link to comment Share on other sites More sharing options...

Shaunie Posted February 11, 2016 Share Posted February 11, 2016 Way back in the day, probably Kate eighties, on 35MHz I flew two models on one Tx (not at the same time) had a guest fly at another club took off (hand launch from a friend) it was a Blob, a modified slope soarer with a .15 on the front. Problem was the ailerons needed reversing. Pressure of trying to impress led me to forget, the moment it needed a correction it rolled straight in, hit the deck before I even worked out what had happened. Ever since that I don't just waggle the sticks, I hold it over to the right and check right aileron up, pull back stick elevator up etc. Piling in a perfectly good plane makes you a little more diligent. Never had a problem since. Shaunie. Quote Link to comment Share on other sites More sharing options...

Kevin Wilson Posted February 12, 2016 Share Posted February 12, 2016 I heard an old wives tail about holding the tranny upside down. Although I doubt I would have the presence of mind to do it. I can see it helping with the reversed ailerons but the reversing of all the other controls would probably get me. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted February 12, 2016 Share Posted February 12, 2016 After an acceptable length of air time, showing a way to fly using the buddy, we hand the tranny to the rookie for further practice, standing beside them. During these flights, the new boy has the luxury of handing over the transmitter when the model gets away from them. On this occasion, after a number of successful circuits, the model gained speed towards the ground, and as usual my response was “ lift the nose……..throttle back……lift the nose !”. In these few seconds, the model was racing towards the ground at a high rate of knots. My prodigy promptly turn towards me and thrust the tranny into me……………up……side……down…………….THUD ! ! !

Leslie Crane 1 Posted February 12, 2016 Share Posted February 12, 2016 Hi Geoff I have done this/had it happen to me a couple of times and one of those was on my Riot. The interesting thing is that on both occasions I had done nothing to the plane or the transmitter since previous flights which were fine. On both occasions I was using a Spektrum Dx6i. I have had others say this has happened to them with their 6i and that it is a known fault. I haven't checked this out but it would be interesting if you also used a 6i. Good job it didn't happen on your recent DB Moth maiden you told me about. Les Quote Link to comment Share on other sites More sharing options...
Geoff S Posted February 12, 2016 Author Share Posted February 12, 2016 I was much, much more careful with the Tiger Moth and everything was checked and rechecked several times. I guess I was getting a bit blase with the Riot after a few 100 flights. No, I was using a Frsky V8R4-II with my Taranis. Somehow the weight of the aileron channel had been changed from 100 to -100 as I discovered when I examined it carefully. It must have been me when I was messing with the settings with gloves on in the cold and wind. In any case I should have checked the controls before I took off as I usually do. It was short exciting flight Anyway the Riot didn't owe me a lot and I like it so much I've got a new airframe and it's ready to go again.

Geoff Isnt it funny how we say it doesnt owe me anything yet we still go to the bother of a patch up, I have a 25 year old fun fly that has been repaired so many times that it is 90% epoxy - still flies mind - but aint too pretty - I would never post a piccy of it Quote Link to comment Share on other sites More sharing options...
