Helifreak Fun Fly

This morning I headed up to the Palomar RC Flyers field to check out this years Helifreak Fun Fly. This is the biggest helicopter fun fly in the San Diego area, with some of the best pro pilots in the nation attending. The flying I saw was unbelievable! I hope that some day I can do one of those maneuvers. :)

Eric took a vid of me practicing side in hovers and slow forward flight today at the SEFSD field on his new iPhone 5!  Thanks Eric!

Repair and upgrade parts for my 450!

I crashed my 450 a few weeks ago due to the tail belt slipping causing me to lose control. So I decided to change the tail drive to a torque tube. Let the rebuild begin.

5 Blade heli! Updated!

Another guy showed up with a 5 blade head scale heli! Cool!

UPDATE!

Added a vid of the heli that I shot with my iPhone 4s.

Another great day for flying!

At the field again. This time trying some different throttle profiles to get certain head speed, which I will measure using my optical tach. Hmm. A little hard to measure the head speed with the sky tach. But my iPhone app says I'm at about 2200 rpm at 80% throttle.

Going back to normal throttle curve as a few times I almost shut the motor off while I was trying to descend. Also I don't think I got a full charge on my batteries for some reason, as my lvc turned on with about 30 seconds left on my timer. Or the batts have a large voltage drop under load, since when I checked them later, the still had 65% capacity left?

Day 2!

At the field again trying out some different speedo programming and throttle curves. Way more power and response than yesterday! Happy with the setup now :)

Update: Hmmmm, now that I've thought about it some, I think I'll try governor mode in the speedo again, but this time turn up the throttle percentage until I get the pop and power I like. This way the cyclic control will feel more consistent. Now I need a shutter style tach to get an accurate head speed reading.

Maiden Flight Day for my Align 550e 3GX!

Today was the first day of flying for my 550! This was the first time I've flown such a big machine. On the first spool up I checked the blade tracking and it was spot on due to using a digital pitch gauge during setup to make sure the pitch was equal on each blade. On my first attempt to lift off, the tail was reacting weird, so I shut down right away. Turns out I got the rudder movement backward during setup. After reversing the rudder servo, resetting the sub trim, establishing the gyro limits, and verifying the gyro response, I was ready to try again.

This time everything was responding the way it should, so I lifted off! The heli was super stable and needed very little input to keep in position. I just hovered, looking for wagging of the tail or swash plate, and getting a feel for the controls.

For the second battery I increased the flight time by one minute. I also tried some collective climbs. The response felt slow compared to my smaller 450 heli. I think I'll reprogram the speedo and redo my throttle curves for next time. I may also get the bigger 550 mm blades.
