Ikarus Eco 8 Setup
I have just built an Eco 8 and am having great difficulty with the setup. There's no one locally who flies heli's so perhaps someone on this forum has built one and can help.
Problem: I can't get the tail rotor to compensate for the torque of the main rotor. That is, it continues to spin counterclockwise as I apply more throttle and pitch. The tail rotor moves as far as possible to try to stop the spin, but it can't counteract the torque. I have the Purple Bull brushed motor with a 9.6v NiMH battery and the Ikarus mini gyro (the Hobby Lobby recommended setup). I'm using the mechanical mixer. Pitch is from +1 degree at zero throttle to 8 at full throttle. I've measured all of the linkages and they are within 0.1mm of the recommendations in the instructions. Originally I had the tail rotor backwards but have reversed it so that the Ikarus name on the blades is on the heli's right side. This is such an old design, I'm sure it works. I just can't figure it out. Anyone have any ideas? |

Hi,
I have had a couple of eco-8's flying, and one eco-8 royal still going. I haven't had that problem, but can suggest 1) Make sure the belt is tight enough and not slipping. 2)You can get different gears(different #teeth) for the tail rotor drive. One with fewer teeth will spin tail rotor faster. I have not used the mechanical mixer, but that is a separate problem. 120 deg swashplate from HL is way too expensive, one for t-rex 500 could be modified. THe stock plastic 120 deg swashplate with eco-8 royal breaks easily. Good luck, Steve K. |
