I need help solving a radio interference or malfunction problem. I decided to try electric power so I put together
a Valiant(a very good flying airplane by the way) with a Plettenberg 30-10 motor and Spin 99 controller.
The radio is a one year old Futaba 2.4 Ghz 12Z,new 6008HS receiver, new 5.2 volt regulator, new on-off switch, and a
Thunder Power 1390 receiver battery. I used Rhino 4900 flight power batteries and 5.5 mm bullet connectors.
I made sure there were no cold solder connections. The receiver battery was mounted in the front of the fuselage
behind the landing gear. I ran the battery cable and the controller cable in parallel down the same side of the fuse
about 0.5 inch apart. There were no filters in either cable.
I started flying the Valiant and was very happy with the way it flew and how well everything worked.
Now, thinking about it, during the first five or six flights the plane went into fail safe a couple of times for a second or two
but at the time I didn't realize it. I thought it was just my bad flying.
After about 10 or more flights with no problems it went in and out of fail safe for more than two or three seconds on one
flight. I was lucky and regained control. After landing I shook and pulled on all the cables while the motor was running
but could not get system to malfunction. I replaced the receiver, on-off switch, battery and regulator with known good
components from another airplane. I oriented the receiver antennas in another position but the same thing happened
and the plane snapped in on a landing approched breaking the left wing in half. After the crash everything seemed to
work o.k. on the ground. Thinking the problem could be the transmitter I put the receiver,battery, and regulator in an
old Venus 40 and I've had no problems, solid as a rock.
Thanks in advance for any ideas or suggestions.
Bill
