| First of all, thank you in advance to everyone who tries to help.
I noticed this problem yesterday afternoon, and have not had much time to research completely.
I have a Hirobo Sceadu 50. As I was increasing my throttle to begin a set of hovering practices, I noticed that my rotor head speed never increased even though my engine RPMs increased. I quickly shut down and begin going through inspection procedures.
I noticed no glaring issues such as breaks, loose parts, etc.etc.etc. I took the blades off and restarted and slowly and carefully watched the main gears as I slowly increased throttle speed. Everthing seemed to begin well, then I noticed a spot where the gears seemed to be spinning properly, but the rotor head RPMs had hit a point where it was no longer increasing. It almost seemed to be slowing down. It was getting dark so really couldn't spend any more time watching it.
This is not a maiden flight; there are about 40-45 flights on the engine and bird.
Tonight I will try to go through the kit instruction book and parts list to see if I can identify some likely culprits. I want to break down the gear and mast sections; but an experienced heli pilot friend has offered to help me out later in the week. However, I just can't sit and stew on this; I want to be able to have some idea of what I am up against.
If I am missing something obvious; try to be kind.. I just finished up tax season; so I obviously have not had much chance to fly or peruse RR until now.
Again, thank you in advance.... |
