I woke up this morning at 8 and could smell something was wrong. I got downstairs and found the wife face down on the kitchen floor, not breathing! I panicked. I didn't know what to do. Then I remembered Wetherspoons serve breakfast until 11.30.

There are two statues in a park; one of a nude man and one of a nude woman. They had been facing each other across a pathway for a hundred years, when one day an angel comes down from the sky and, with a single gesture, brings the two to life. The angel tells them, 'As a reward for being so patient through a hundred blazing summers and dismal winters, you have been given life for thirty minutes to do what you've wished to do the most.' He looks at her, she looks at him, and they go running behind the shrubbery. The angel waits patiently as the bushes rustle and giggling ensues. After fifteen minutes, the two return, out of breath and laughing. The angel tells them, 'Um, you have fifteen minutes left, would you care to do it again?' He asks her 'Shall we?' She eagerly replies, 'Oh, yes, let's! But let's change positions. This time, I'll hold the pigeon down and you sh-t on its head.'

A man walks into a bar and sits next to a man and his dog, after a few minutes the dog turns to the man and says Hi there matey, can i buy you a drink and have a chat, i have lots of great stories to tell you,.......such as the time i spent travelling with a team of Huskies to the north pole and back in temperatures below minus 50 celcius,..........or my time in the Hilamayas when i carried all the gear for a ten man team for their assault on the summit of Everest, now that was a real struggle i can tell you!,.......or perhaps you'd like to hear of my heroic action during the Gulf war when i single pawedly rescued a squad of soldiers from certain death by pulling them to safety with these very teeth, (points to teeth) after they were ambushed by insurgents"? "Wow", the man says to the dog, "you can talk"!! .........Wow the man syas to the owner of the dog, "your dog can talk"!!! "Yep" he says, "d'you wanna buy him"? "What"? says the man "how could you bear to part with such an obviously intelligent dog which can ACTUALY talk"? "Easy" says the man "he's always lying"!! Edited By Vic.

What's the difference between a dead banker and a dead cat on the motorway?.. .. There are skid marks in front of the cat.

DEPRESSED PM A man on his way home from work in central London came to a complete stop in heavy traffic and thought to himself, "Wow, this traffic seems worse than usual, nothing's even moving." He notices a police officer walking back and forth between the lines of cars so he rolls down his window and asks, "Excuse me Officer, what's the hold up?" The Officer replies, "It's the Prime Minister, he's so depressed about all the recent corruption scandals that he's stopped his limo in the middle of the street and he's threatening to douse himself in petrol and set light to himself. He says the whole country hates him but he can't resign yet because he hasn't got a big enough pension to retire on. I'm walking around taking up a collection for him." "Oh, really? How much have you collected?" "only about a hundred litres so far but I've got a lot of folk still siphoning." _______________

Japanese scientists have invented a new type of camera with a shutter speed so incredibly fast that they are now able to photograph a woman with her mouth shut.

Looks like i'll be fitting these back on the Sebby with more snow forecast later this week.Got to say it's much smoother off snow with skis than with wheels rattling on a frosty frozen flying field.

JP Prangster converted to electric?
Vic. P. replied to Vic. P.'s topic in General Electric Flight Chat
Thanks for the replies Tim and Plummet We had a feeling it might be a bit underpowered so we should really be lookig at something around a 40 to 50 size electric set-up for it. -
Hi folks,A friend of mine is building a JP Prangster and wants to convert it to brushless powered. I have a Hacker power set with an A30-14L motor and an Xpro 40 amp esc going spare and i'm wondering if it will be enough to power this model with say an APC 14x7e ? Although the Prankster has a higher AUW than the Sebart Katana which the power set is recommended for, would this set be enough to power the Prankster comfortably as a trainer? Has anyone else converted this model to electric and if so what power train did you use? Any input would be much appreciated and thanks in advance

Hi Tom.Is this beginners guide intended for contra rotating helicopters only? If not then there are a few points which need to be clarrified. First, it says " Never drop the throttle stick or let it spring back for the landing" the bit that's wrong here is spring back. The throttle stick should not have the spring engaged at all and therefore should not be able to "spring" anywhere, if it did, then it would make for a very dangerous set-up!!! Second, when it says "throttle off immediately to save the motor and the rotor shaft." this would be fine for a contra rotating helicopter but not for a collective pitch helicopter. A collective pitch heli should have a properly set up Throttle hold switch and pitch curves. By using throttle hold, you cut the engine or motor but keep control of pitch allowing the pilot to flair the heli close to the ground as with auto rotation landings using 9 to 12 degrees of POSITIVE pitch which will also slow the main rotor blades down much quicker resulting in less damage to the drive train and blades. Suggesting that cutting the throttle is the way to do it is in fact wrong for collective pitch helis because in "normal - hover" flight mode this will give you 2 to 3 degrees of NEGATIVE pitch at zero throttle which will encourage the blades to keep turning and increase the descent rate resulting in a much harder crash.

Oh, and one more thing Michael...........if you haven't already, then i'd suggest you join RcHeliAddict.co.uk you'll get far more advice on all things heli related

Hi Michael,The servo ball link is in the right place, don't change it, it's there for a reason and the travel adjust menu should allow you to set the end points, you don't need to do this mechanicaly. The reason it's at 10mm is to avoid the servo having to use a large arc of travel to achieve rudder deflections, with it set at 10mm the servo dosen't need to travel as far and therefore you get a faster rudder response which you need if the gyro is to be efficient at making corrections in Heading hold and rate mode. The travel adjust should remove the difference in travel on right and left inputs due to the tail offset at neutral, ie, it will usualy have more travel to the left than the right once the tail offset has been set. Press and hold the "set" button for 2 secs and then press it again (about 3 times i think) until the travel adjust led is on, now move the transmitter stick carefully to the left first to the point you want the travel to reach which should be just short of full travel, then move the stick to the right until again it's just short of full travel and then press the "set" button. Now switch off the reciever and switch on again waiting about 5 secs for the gyro to re-initialise and you sould now have the travels set. Bear in mind that once you have adjusted the rudder offset in "rate mode" by moving the tail servo mount to get the correct deflection to enable the heli to hover without any tendancy to yaw that the travel end points will have changed so you will then need to reset the travel adjust points again. Hope this helps.Vic.

Sounds good Dan!!Just remeber to use the space bar after commas and full stops and you'll do fine

Last Sunday i decided to prepare my Sebby for the snow so i set about designing some skis for her. I made the skis out of 1mm thick ply laminated to 3 layers to hold the front curve and glass clothed and epoxied the undersides ready for wax. I designed the mounting and damper to fit the original axles so they are an easy swap when needed.The skis are angled nose up so that the back of the ski contacts first on landings and stay reasonably horizontal during flight. they also pivot on the axle with a small strip of high density foam between the ski and rigid plate to act as a damper. The tail ski is a 2 ply of 1mm and is a tight fit over the tail wheel (not the original Sebart tail wheeel) and the unsightly elastic band is to keep the ski nose up. I intend to improve on the lacky band. I went out yesterday to test them and was pleasantly surprised to find that they worked really well, and it was a much smoother take off and landing than with the wheels and spats on a bumpy footy field. It flew very nicely without any nasty surprises. Some photos of the skis.......oh, and i added the pilot (a cutout photo of me) because it always looks odd with an empty cockpit Front ski close-up Tail ski close-up Edited By Vic.

Yep, that's some pretty awesome flying and amazing reactions!! Many, many years of practice and a large bank account for the inevitable repairs. Check out Alan Szabo flying a Trex 600 ESP electric heli, similar moves, different style. Edited By Vic. P. on 01/01/2010 23:29:57 Edited By Vic. P. on 01/01/2010 23:30:29

Hi Garry, I would have a go at re-binding the reciever as it may be that the failsafe is not set correctly. The throttle stick should be in it's lowest position during binding. Hope this helps, Regards Vic.

Hi Allan, Generaly, if the tail is hunting,(left-right oscillation on pirohet stop) then the sensitivity is set too high. Reduce the sensitivity slowly and test between each adjustment until the tail stops dead after a rudder input.. For "normal" flight, the sensitivity is higher than for idle-up flight and a value of around 70-80 percent for normal and 60-70 percent for idle-up should be a good starting point.. If your gyro has a "delay" function as well, and you are using a non-digital tail servo, then this may also need to be adjuded to suit the servo's speed. If you are using a digital tail servo then this needs to be set to zero. Hope this helps. Vic.Edited By Vic. P. on 03/11/2009 07:33:34

Hi David, The rear switch Thold/mix on top left of your transmitter should work to switch off butterfly and allow the throttle channel to become throttle. Assuming you won't be landing under power, this can be switched back to butterfly for landings! This of course assumes that this switch has not been assigned for another channel. Hope this is of some help Regards Vic.
