Engine Slows down after Half Throttle
Hello Men,

Have now adjusted radio and turned down REV Mix to all 0% settings and now the gyro and rotor work properly and have lift now.

This is a big improvement and can get it up a couple feet slightly after half throttle. Now have found another issue with the motor rpm.

The next issue I am working on is the engine speed seems to decrease after that when trying to increase for speed, the engine bogs down and goes down in rpm. Have adjusted the mixture screw to about 2 turns out and will try both sides of this from 1.5 up to 3 and see how she responds.

Can someone give me any advice on what else to check on that problem please?

Cheers

Bill

too much pitch. initially set up your pitch to -10, 0 , +10 then from midstick hover, do a climb out. if you notice rpm slows or bogs down, decrease pitch from 3/4 of your pitch settings (play around with the values until you are satisfied with your rpm and climb outs.team solo

Hi,

Well have 1st done the mixture screw and now at about 1.5 turns out and that has fixed the problem, now have very good power and no loss when increasing throttle. Did not think it would affect it that much as it was only 3/4 a turn difference, but I am a newbie to this.

I will review and read the manual on the pitch values you describe to me and play with those settings in the radio.

thanks for the help, really appreciate the help you are giving.

Cheers

Bill

Hi,

Thanks for the advice and link on the tuning section, very interesting.

Now I have more reading and learning to do. My Hirobo bird is flying okay now and fixed the 2 main issues I had. Now to start learninghow to fine tune things. At least at a better state than when started.

Thanks for all the help everyone, much appreciated.

Cheers
