hah andrew another nice addition... think i can add one from this mornings park session -put the bungee peg in the ground and stretched the bungee out.then thought i better check the trims again on the fling so facing away from the peg stuck the fling between my legs with the leading edges against my thighs (marvelled at my own on the fly "genius" ).basically what i didn't take into account was how soft the ground was after the rain and also how much a plastic peg stings when it hit's you in the a*se at speed! let's just say i said i few bad words,hobbled around like a madman and made a couple of loitering school kids giggle

I'm afraid bungees have a very high potential for producing klutz moments of the most spectacular kind. One such incident happened to me today... I thought I'd try launching my dad's Bee with my bungee - being pretty light I figured it'd go ballistic. I decided to use my own TX rather than dad's, because his doesn't have dual rates and the elev throw is too much, which could be a big prob at bungee speeds. So with the right channel selected and the elev throw dialled in on my TX, I hooked one end of the bungee to a barbed-wire fence post and the other end to the Bee and gave it a nice long stretch. After release acceleration was pretty crazy as expected - but alas it just kept flying straight, pitching down slightly - all the way into, and through, the barbed wire fence at warp speed . Oh oh... this could be ugly. When I got to the grief-stricken Bee amazingly it didn't look too bad, the worst damage was to the elevon hinges which were torn on both sides, a few dings and scratches here and there, but nothing severe. Hopefully a fairly easy fix . I couldn't for the life of me figure out why it didn't release - the hook was the same one I use on my Skua. Then I moved the sticks on my TX and... the elevons were working backwards! D'oh! So when I pulled up to release from the bungee it dove into the fence instead... I had what felt like about 0.5sec to figure this all out before it hit the fence - needless to say that was not enough time!

That had me chuckling to myself, I thought I was the king of backward servo operation. I'm glad it all ended ok though!!!!

Good work Sean! When I was fairly new to the sport I got my first hot lo-wing aerobatics plane. I was probably 15 or 16 at the time. It had a 45 fsr-abc with a tuned muffler so this plane had nearly adequate power (LOTS). Anyway I took off, and it rolled a little. I corrected it but it got worse. Then I thought "aileron is reversed" and I leveled it off. It was slowly rolling (needed a couple of clicks of trim) and I remembered the effort I went to checking it and promply rolled it into the deck at nearly mach 1. DOH. Fortunately it survived and I went on to have much fun with that plane. It's the only time I've ever done that

About a year and a half ago, my son was excitedly waiting for pre-flights to be completed. An experienced flyer at our little club was giving him a buddy-cord flight on a fuel-powered trainer. The owner had flown it a few minutes earlier, then took off the aileron wing and put on the dihedralled no-aileron wing, ready for my son to fly it 3-channel.
They went out on the field, plugged in the transmitters. The experienced guy brought up the throttle, it rolled nicely, nosed up, then went into wild low-level aerobatics. Those of us back in the waiting area thought this was a bit radical, especially as an example to a young impressionable boy.
The radical manoeuvres became more radical (a short period of 10s or so, but seemed longer), then finished with a crunch and bits of balsa fountaining out (OK, I exaggerate here a little, but it was a spectacular mess). I was in shock - I really hate the crunchy aspects of flying. My son was stunned, and very disappointed. The other guys were, um, cynically chortling, as I recall.
What had happened was that on the guy's Tx, he had two model settings both with exactly the same name. One was for this trainer as 4ch, the other as 3ch. And, you guessed it, the rudder-connected-to-the-aileron-stick setting was a servo reversal compared to the 4ch setting! So when it tilted left on takeoff, he corrected softly to the right, but it tilted further left, and so on, and in the short time he (didn't) have for thinking, he tried some elevator to get him further off the deck while he tried a little harder to correct the tilt. Nose up, wing down, round it came, crunch. Sad.
Don't you just HATE servo reversals?

I did it recently when I took the old Bee over to SC for the first time in ages. I think I quickly copied another model memory for it, had a quick fiddle to check the throws, and in front of Mark, Mike, and a few other guys chucked it off and pulled up harder and harder as it arced down to crash onto the beach below. Elevator reversed!!
Greg (a flying mate from Peachester) had his huge Bird of Time , balsa builtup rud/elev at Pedwell Rd last year and threw it out ... soared away beautifully, slight left turn, which got tighter and tighter and it flew back into the top of the rainforest trees behind us! Rudder reversed. Took ages to get it down.

Yesterday I managed to get my Skua stuck in the top of a tree - not once but twice. First time was in a low tree and was fairly easy to get down but second time it got stuck in the very top of a very tall tree. There was no hope of getting it down so i just kept flying but with a different plane. The wind managed to dislodge it a little and it fell down a couple of branches but there it stayed and didn't move any further. So I was forced to drive home with it still up there, and resigned myself to the possibility that i might never get it back.
I drove out to the flying site this afternoon and thankfully it was on the ground directly underneath the tree it had been stuck in. It was really windy and raining here last night, so it was a little damp but in perfect working order. Phew!

andrew knows of a little video i have of him launching his reaper up at Bald Knob... For my safety it's not on the net, but stored safely away in my private little stash... "Andrew... can i send it into Funniest Home Video's..... Pleaseeeeeeeeeeeeeeeeeee???"

Most recently. the wind was blowing nice S.E being at a loose end went to Binna burra o fly a new design. Of course the hanggliders were out in force plus associated tourists. So I string my plane together range check and chuck it off, all looking good, steep descent to get up speed(no just incompetent trimming) lift takes it above the Hill, so a steep left hand turn over the cables, oops forgot the two big norfolk pines. The pines are now rushing up and there is loud sound of branches sucking in glider. OOps so what o do, well not much, several people are laughing, not me ,Im distraught, ,so if you go to binnar bura and think norfolk pines have yellow flowers your wrong, it's my glider which now resides in the top of th tree.

Oh no!!! Are you sure you can' t get it down?? Once you're up into a Norfolk Pine there are plenty of branches??
Also this raises the question: where can you fly at Binna Burra? I didn't think it faced SE. More information please!
I also have to add that I've done so many klutzy things lately I've had to hold back from posting on this thread or I'd jam up my bandwidth.

Hey Andrew, Binna Burra is actually Beechmont. Beechmont is on the road to Binna Burra. Actually surprised you don't know Binna Burra, as you are a keen bushwalker/climber etc,. You'd love it up there. Take warm clothes though. Beechmont is 2500ft above sea level and the lift is known as some of the strongest in Australia. Good to go up there on a strong wind from SW to E as the hangliders and jellyfish don't fly then. The down side is the trees off to the side are huge. I mean, massive plane eaters! I guess like Mt Mee if you lost it out to the side. SF2, may be no use but, if you look in the bushes below the powerlines there is a large stash of different sized conduits. I have seen guys tape several together and get down planes from amazing hieghts. I have used these several times myself. Eric

Flying maleny last week end. Had brandenburg( spelling?) rd to my self for awhile till parra glider showed up. Rang girlfriend up to say thermals unreal and would be back bris late only to have parra mumble something about me getting stuffed after he bombed out and was getting his breath back after walking back up saddle road. Rc one parra glider Nil. Kept telling him rc is fun with him mumbling something under his breath probably get stuffed again. I reassured him the sea breeze would pick up around 12 and he just glared at me with a mean brow with beads of sweet laying upon his forehead.Well i had enough of thermals with 2 meter fling and got zagi out and carved up the sky only to hear cars pulling up, with at least 6 over grown kites beginning to set up. Out numbered stopped flying to have chat. They reckon they would leave slope to myself and wow wings and young fella (sorry bad for names) as they would get up and fly eagles nest slope. So they did.Well young fella launched and I checked his tx to see what he was flying with, Ahh short aerial must be 2.4. He was flying close then out from slope, back down wind with major glitch in control only to recover back close. He made comment about glitch and i glanced back at tx again and I told him not to bother with range check as he had just completed. Yes been there done that . Once with perfect launch of bungee with brolga not responding. Perfect glide and landing only to have cow spooked and tread on after so many paddocks crossed. Yes quick control check always. Not as bad as hang glider pilot not hooking up before he jumped out off rainbow at comp few years ago ! ! good days flying with good company. brought back memory's
