Traffic, Park Flying, and my new Futaba 14mz
Friday, June 27, 2008
West Linn, Oregon
In the Process of going out and about, I got stuck in a horrendous traffic jam that put me far from where I wanted to be. Yesterday I decided to purchase a Nikon D60 with and two lenses to keep up the picture quality for this site, and I set out earlier today to take some pictures with my new camera. My friends in Oregon City at FlexPro were going to work with me to get some pictures, but we ran out of time and they had to hit the road for an appointment. My friend Spencer Scott and I set out on what should have been a 10 minute drive to Clackamas, but it ended up taking 2 hours. By the time we had accomplished our menial errands, and gotten an ice cream to cool our nerves, it was time to fly!

I stopped at Meldrum Bar Park in Gladstone Oregon to fly. The park is situated on the Willamette river, and the ball fields are commonly used for park flying. I flew a couple of packs with the MSH Protos 500, and Spencer took the pictures. I recently started flying with a Futaba 14mz radio, which is proving to be much different than the JR X9303 2.4gHz Spektrum radio I had been using. The Futaba feels great, but I am not used to it yet. With the Futaba, it feels like my rolls are much more axial. The interaction seems to mostly be eliminated with a feature the Futaba has, the servo speed compensation in the swash mix. This setting gives you a number from 0 to 100 to compensate for the fore-aft/ cyclic interaction. When you rock the swash plate fore/ aft very fast with a 120' CCPM model, the center servo has to travel further than the side servos to get the same position, so the slower the servos are, the more interaction you will see as the swash rises and settles with fast cyclic inputs. With really fast servos you won't see any interaction at all, but even servos with a .11 sec transit time will show interaction with fast inputs. The Spektrum gives you a exp function in the swash menu that can be turned off and on, but it only helps in some situations. With the Servo Speed compensation feature, I am able to all but eliminate any interaction with any speed servo. The results are dramatic as I am able to do rolls backwards, stop, go forward, stop and start going backward again. I can pop the model up and do vertical rolls. I can do forward and backward rolling circles and rolling loops now, where as all those maneuvers were out of my range with the other radio. Being so much more in tune, it is taking some getting used to.
My 14mz is a hand-me-down from a friend, and the folks at the Futaba service center had to give it some TLC on it before I was able to use it. Its on 72mHz, but the system has 2048 resolution, and I am able to change to any frequency on 72 mHz. The cool thing about the newer Futaba module system (on the 10c, 12FG, 12z, and 14mz) is the radio outputs the raw data stream to the module, unlike the older systems that sent the PPM data stream to the module. The result is I can use my 72 mHz module now, and switch back and forth between the Futaba 2.4 gHz FASST system. Both systems with provide 2048 resolution with the high end receiver. I simply love the look, feel, and performance of the radio!
until next time, happy landings
