  1. Thanks for the reply. Nice to have contact with original designer.I will put 15 degrees and use dual rates to have half movement for normal flight. There used to be (20 years ago) autogyro.com page for rc autogyros. It had also a technical page for basic setup, hang angles, balance, basic control movements, rotor loadings and so on. Maybe it was old information, but information gathered nicely in one place. I wonder if there is similar page nowadays? My inspiration for autogyros came from Crimson Skies computer game. There was autogyros. After finding ready made balsa blades from our RC club I started to create a model around those blades. Handwork on wooden parts was not very accurate and models tended to wobble through the air as the bearing was "almost at the center". Nowadays I have access to CNC-router and 3D Printer. That makes life lots of easier to build rotating autogyro things. The first design (one with short red fuselage) flew... about 20 meters before falling to its side. Something was wrong with this design, horribly wrong.   Second design was using blades from 1st design and put it to Blue Stick (red longer fuselage) RC trainer. This was better success. It flew relatively well, did loops and was able to glide with no engine cut off.   My third design was build over modded and self built glider fuselage with electric motor.Aim was to make it lighter. This was achieved. Gyro number 3 wobbled through air and landing roll was often zero meters. Therefore the broken landing gear was just replaced with a carbon tube placed sideways to the fuselage.   Sorry about the bad video quality. To be positive, every video nowadays is better what comes to the quality. The first gyro on the video is gyro number three and the second red gyro is gyro number two.   Edited By Jussi on 07/01/2021 21:23:41 Edited By Jussi on 07/01/2021 21:25:46
  2. Hello, my SAB Goblin Urukay helicopter likes autorotations . However he just can't seem to find any friends to share same interests. So I had to build a friend for him - Revolver 2. It will fly all of the flights autorotating! I have designed and built some autogyros long time ago. After that it took many years doing other things. This year I thought it would be nice to see what ideas others have on autogyro designs. It was a tough pick between Panther autogyro and this Revolver. So I ordered Revolver 2 short kit from Sarik Hobbies and head parts from Coolwind. Maybe I get some nice ideas for my next design from this build The kit will be build much as drawn on the paper plans. Only small changes are made. One of those is visible, the tail boom is not straight. This makes it possible to use 1" bigger propeller or lower the motor. Colors follow the Urukay helicopters colors but some green will be added to the right side to help orientation. How much would you recommend for aileron tilt? Does open cockpit affect much to essential aerodynamics? I think it would look cool with open cockpit.
