Hi folks
I've been flying for a while and recently got into multirotors, built a tricopter to David's design, then made a few changes and now I am up to version 3 of my own take on David's tricopter.
It flies great and is the most stable and responsive tricopter I've built yet. However, I've had a problem in that the last two flights it has unexpectedly crashed.
I've put probably 5 batteries through the tricopter testing hovering, going up and down and general flight, with no problems. However when you fly FPV you do tend to fly further away! My suspicion is that my radio link is dropping out which is causing the crashes. I'd like to confirm this by checking with some experts here
The tricopter flies fine and then suddenly spins out of control.
In both crashes, I was at approx. 90 degrees to myself, eg:
---------------------
---------------------
-----me------Y-----
---------------------
(Y is the tricopter)
In both cases I think I am less than 250m away from myself, and with no obstacles.
I think this is relevant because my DX6i antenna points at 90 degrees.
Here is a video of the most recent crash - it was a fairly windy day but the tricopter seems to fly quite well until it suddenly crashes. Listening to the audio, the motors sound like they just switch off. As I was flying, once the tricopter had rolled over upside down, I killed the throttle so as to avoid flying into the road or some other obstacle. I'd rather have a crashed tricopter than someone hurt!
Currently I am using a DX6i with an OrangeRX R620 and Satellite receiver.
Motors are 888kv CarbonBird from MultiWiiCopter
Props are 9"x5 Triple Bladed Props from MultiWiiCopter
ESC's are 18A Turnigy Plush as recommended by David
Control board is a KK2 board running firmware 1.2 I believe
Battery is a 4S 3700mah
Here's a picture of my tricopter which shows the placement of the receiver. The FPV transmitter is on the rear tail boom.
If anyone can give me some idea of if they think it is the OrangeRX receiver that is the problem, or if it could be something else that would be great, as I don't want to replace the receiver and then have to rebuild my tricopter for a third time!
Thanks for your help!
