They are a great plane to fly when all the rest are in the hanger, good vid cubber1 have you thought about using a gyro linked to either one or both of the airelons to steady the plane. Helps with the video and really makes take off and landings a little less stressful in extreme conditions. There is a very good thread explaining how to set them up here https://www.rcgroups.com/forums/show...fitting+gyro+s I placed a cheap Hobby King HK407B on my AXN and it has help prevent some potential disasters on landing in strong winds.

By the way.. today i found the CloudsFly wiki, tons of info ans sugestions.. but one particular line puzzled me.. " Replace stock 20A/25A ESC for a safer more capable 25A or 30A, using a higher rated ESC than necessary will run inefficient, less flight time although cool ESC, now comes with 25A ESC stock " Taking out the weight issue.. does that means that using a 40A ESC rather than a 30A will decrease performance? |

The extra weight is how it can decrease performance - every extra gram increases the stall speed. However, 10-20 grams extra is not exactly a problem with my style of flying. If used as a motored glider looking for thermals, I guess all extra weight is a no-no... The sentence you quoted did not make much sense, on the one hand it asks you to replace the stock esc, on the other it tells you that a higher rated esc than necessary will decrease performance. As far as I can see, the stock setup runs cool enough on a 25amp esc, but will not run any worse on a 30amp, except that it may have a few more grams of weight... |

If you feel the weight of a slightly larger ESC is a detriment, you REALLY should go to a smaller 3 cell lipo. I can fly mine with an 18A ESC (HK Turnigy "Plush" model) for at least 30 minutes of climb and glide style with an APC 6x4E prop on the stock motor with a 1300 mAh 3S lipo, which weighs over 2 oz. (about 60 gms) LESS than my 2200 mAH packs.

I would not be worried aout the SLIGHT extra weight of a bigger esc. I just started flying with a gropro and fpv tx attached to my CF that added about an extra 190 grams! Granted it does fly alot slower, climbing has decreased signifigantly, and it stalls alot easier...but it does fly smooth as long as you handle it properly.

An hour in the air with one.... my neck gets very stiff looking high over head after 20-30 minutes! |

Flew my AXN yesterday in 15 - 20 knot winds (blustery) and got some great height at my friends farm in this valley. Had 20 min flight (timer) and when I brought her down each cell still read 11.95!! (I usually plan to get to about 11.8) This was a buzz for me because even in those windy conditions I had good lift and lots of gliding with no motor. But like you said Tom, that is about as long as I can stay focused with my neck craned back like that.

I run with a 2200 3s lipo which fits nicely in the plane, esc is attached to the underside of the cockpit cover. With this arrangement I can easily get an hour and ride thermals no problem but yes the neck gets sore, need a nice banana chair to lay back in
When I upgrade the motor I will probably place the esc outside in front of the motor pylon to get more air and add some air scoops to the front for better battery cooling. Cut plastic spoons will be most likely the scoops. Can't wait to get home next week and fly! |
