Blade 450 3D Blade Tracking Problem Fixed!

[helicc16]

Hi, guys. For those of you who are unfamiliar with this thread. I had ( at least I thought I change) a problem with the main rotor blades keeping going out of track. At first I thought it was a loose part or a bad feathering shaft in the head assembly. After changing the feathering shaft and making sure that all the parts are all nice and secured, I now had a problem of the blades changing from as much as 1/2 inch lower to 1/2 inch higher than the other blade with just half of turn of the link rod!

Thinking that I might have hit a dead end, I just sat there spinning main gear hopelessly. Suddenly, I realized that the motor is not a stock motor ( 420 rated at 3700 kV). It is a 440 rated at 4200 kV ( stock motor on the Blade 450 X).

This explains everything. At 75% flat throttle curve, the blades was over spun. The stock wooden blades flexed excessively because of much higher head speed, making them change the tracking so much with just half of turn of linkage adjustment. This also explains excessive power consumption.

Lowering the throttle curves about 13 points across the board solved the problem.

Good deal bro. Now with your flying skills, you need to upgrade to some CF blades. Shoot for a 2800 head speed max.

Wooden Blades??? I must have missed that in the original post... .... well if you had mentioned that ...... They are notorious for tracking issues due to their high flexing under load and are not good at high head speeds.

Good Spotting! ..... Well Done!

Thanks, guys.

Westy, I should have described the problem more thoroughtly

Tony, I am not as good as you think I am. Just crashed the ESKY D700 3G this afternoon. I have the strong wind to blame but ultimately it was me -- trying to flip bird too close the ground.

Now that it's been fixed, the Blade is on sale on eBay.
