    Nick Name Do Do
    While the forum is a little quiet I have a “true” story to tell.
    Several months ago a well-dressed man came to my shop to purchase some set up tools for his new heli. He had purchased a JR Vorsa 450. He told me he has assembled it according to the manual paying strict attention to the linkage lengths in the instructions. After a short time I told him that it was unnecessary to purchase things like swash leveller and pitch gauge as I would loan these items for free provided he left me a deposit should he not return them. Mind you it was the first time I have ever seen this gentleman hence the deposit for the loan of set up tools. After explaining the initial radio set up with a linier pitch curve I explained to him to simply connect the servos to the appropriate channels in the FBL unit and before fitting the arms to the servos to push the throttle to 50% and fit the arms as humanly possible to 90 degrees to the main shaft without using trims of any kind. Then without fitting the horn screw to the servo check that the swash moves in the correct direction, e.g. left the swash moves to the left and to only initially connect one servo arm at a time so as not to get confused .With this single arm connected check that when forward or elevator input is applied that this servo makes the swash tilt to the front of the Heli. If this is not the case either reversing that channel or
    In the swash menu simply change that servo to a minus instead of a positive number if it isn’t doing all 3 inputs in the correct orientation. Once he has successfully got this servo doing all the right things apply that to the other 2 (pitch-elevator) as he has already set up the aileron. After this is completed while the throttle is still at 50% then slide hex key into the blade grip and see if the shaft of the key is parallel to the main shaft and adjust the links accordingly looking and turning the head side and front on. Now you have a level swash and zero pitch at 50% throttle and stick position. Now for the tail I told him to simply rotate the blades in the grips until the tips touch and look they look centered and then adjust the tail rod until they do. I realize that many allow a small thrust to the right but with HH tail gyros it will instantly compensate for the thrust. Anyhow these basic setting suggestions will get any heli to fly. Then it’s just a matter of checking the compensation and direction of the FBL unit to make shore it opposes the swash and tail movements. As Jr helis in their set up manual suggest various flight modes and throttle curves I told him to refer to the instructions and copy them to his transmitter. As normal I offered to him to bring the heli back to me so I can double check his set up prior to his first flight Well a couple of weeks passed and guess what he was at my field on a lovely Sunday morning assembling (forgive me a PLANK) Wow- this model was exceptional and after a small conversation he told me he designed it and had it made in a factory in China. It was as he explained a prototype version 1. After completing assembly of this model he went to his car and returned with his little JR Forza charged up the flight pack. We conversed for a short time and he told me he had vigorously spent many many hours on the sim flying helis trying to lock in his mind the various orientations and corrections required to fly these demanding models. In his words he liked the challenge. He then loaded the battery, done a pre- flight check and proceeded to the flight line ,placed the model a good 10 meters away and got up to a gentle hover, seconds later I could hear the head speed change and “OH MY GOD” it was (the heli) preforming practically every manoeuvre possible. Aproximently 5 minutes of choreography controlled flight he landed retrieved the model and calmly walked back to the pits. Well I confronted him to “explain” as I was led to believe he was a novice. He assured me that in the two weeks since I last saw him he has virtually spent the whole time practising with the model and simming well in to the early hours of the morning to achieve this result to date. In my mind I convinced myself that if I hadn’t seen it with my own eyes I would not believe it to be possible in such a short time. Here’s a link to his Quiet flight taken by his shaky friend who tried to capture one of his flights.

      Not that Do Do needs to progress! my heligod what an awesome pilot. I was watching more of his 3d plank videos, truly inspiring stuff. If i were to fly planks, thats where my heart would be I assure you. But I wonder why some plankers attitudes are against 3d flying? To me 3d is at, super maneuverable, fast, more skill level. How could you not respect that? Why do you think the traditional boys are against 3d @feral?

      Dont really know @smakmeharder I dont think theyre brains can fathom what is happening therefore they just hate it.

      Not all the traditional boys are like that I have a very good friend of mine named Laurence Lo he is 80 years young and hovers 40% 3d planes on the deck with smoke pissing out of it.
      He competed in the 1975 tournament of champions circus circus las vegas
      ( look that up its an invitation only aerobatic comp)

      thier argument is a real plane can't do that so you cant make a model do that

      Real plane can do it the limitation is that the pilot would die.

      Rob Holland is the closest real life pilot to 3D
      Really skilled and brave pilot

      Even if you make a real plane RC I still don't think it can do reverse rollers on the deck. The power just wouldn't be there and the wings will probably snap in a crank shaft or a wall.

      Wow, thats awesome... I have a PArkzone Visionaire and I love it. Cant do anything close to what this Do Do gentleman does though.. scale flying and basic 3D is simple, but when you start getting into the complex maneuvers its a steep learning curve, too.

      The wind and your airspeed goes with you or against you if you dont know how to expect it, adjust and use it to your benefit

      Ido was the 2011 European EXFC champ and is a very nice guy to talk to. I know the club Fred is talking about. The rule brought in stated all pilots who wanted to fly anything powered by an engine greater than 20cc or EDF of 4S and above had to do a proficiency test to prove they could fly the model within the boundaries of the field. This was in the aftermath of a large petrol Yak that went out of bounds and flew into the power lines at the end of the field. Unfortunately drivers on Eastlink got the wrong impression and the emergency services arrived. The frustrating thing about this test was that the CFI and president were the only people who could assess the pilot and they were not always at the field. They did relax this later to allow some instructors to do it, but by then nearly all the large model pilots had moved on.
