FX070c - Fixed, and somewhat flyable

The assessment.

The assessment

Since the last post,

I’ve been able to rebuild the Littlebird to a point where it fly’s again.  I’m still waiting on my laundry list of replacement parts to arrive, and I’m having some communication problem with BangGood.com’s customer service.   Since the May 5th delivery and discovery of damage during shipping, I’ve had replacement parts on order.  Some have been delivered.

2015-05-16 20.12.45I received my training gear, It is something totally worth the cheap investment, because now, tipping over the helicopter becomes difficult.   I like to put full control during take offs and landings, where I’m controlling the throttle pitch and yaw precisely for fast changes.  Wind is a major factor in a successful landing.

Fully assembled and attached to the Littlebird, it helps balance the helicopter for takeoffs and landings. I’ve only been able to fly indoors lately due to the thunderstorms and windy days lately.   2015-05-16 20.17.02The length of the supports and the balls on the end, balance very well for my needs.  I had to readjust the front and back support to side to side, because of tipping. I strafe side to side with my heli, and tipping is a risk.

 

Besides the amount of tape used, to rebuild the frame/chassis/head cover the biggest problem I’ve encounter since day one, is the electronics/motor supports.   Internally some of the screw points that connects the chassis to the mechanical motors and servos, those points are broken/stripped and loose.

This side took most of the damages from the nose dive.

This side took most of the damages from the nose dive.

So rattling is probably the lead cause as to why my helicopter flies so “wobbling”.  I used more electrical tape on the inside to help support the frame.

However it flies, and I have to constantly counteract the issues from the 3-axis gyro being affected by rattling, and bouncing.

I received my balance charger for my batteries. I’m learning quite a bit about the R/C world. I plan on picking up a few more batteries for my heli, because to fly for 30 minutes is what I want out of this thing in the long run.

Eventually we will go Brushless Motors, with ESC controllers, CC3D flight controller. I’ll add heat sinks to help the motors stay cool. With a Open Pilot CC3D flight controller, I can program settings using my laptop.  Possibly a bluetooth/wifi module to receive telemetry data.  Eventually a FPV camera with proper lighting, and I can fly longer distances watching through a wireless connection.   Oh the possibilities. 2015-05-16 20.24.27

The spare battery I ordered, is a slightly larger battery, and I expect it to help my fly time last longer, and provide the power I need when I have to counter act wind.  I’ll need the power… MORE Power!   The little electronic thing attached is the voltage alarm/buzzer. This will help me at least know how much fly time i have left on a battery.  I’ve really only been able to fly indoors so it’s safe bet I land before the battery truly dies out.

I notice the lack of power issue, after about 7 to 9 minutes on the stock battery. 11.1v 1100mAh 3S, 20C LiPo battery.

With the new battery, I get 10 – 12 minutes. 11.1v 1500mAh 3S 40C LiPo battery.  This battery is rated to push more power towards the end of its “juice” cycle. Which pretty much means, my Volt Alarm sounds at the last moment before the battery is dead and I have a flying brick coming down.  (Hasn’t happened, yet)
