OH NO man, so sorry for you! 6 months from the 1st ordered parts, and... Straight home to let Jim Jefferies do some 'language' for you!?

The tail mechanism attaching screw that fell out was still loose in the tail which of course will take a massive amount of disassembly to get back in place.

At least on the surface I think part of my issues relate to the relative immaturity of iNav when it comes to Tricopter so I'll switch to Clean or Beta flight (maybe even Triflight) in the hopes that I can leverage some of the support forums.

I'd suggest giving the latest Triflight beta a go. Betaflight really isn't very tricopter friendly (or Cleanflight now that's it's effectively the same thing) as the yaw D-term isn't there any more and it really is needed for a tricopter.

If it's any comfort to you, the S800 Skyshadow flying wing that I spent the weekend building now looks like a similar pile of parts after four unsuccessful attempts to launch it.

Ah well, "build, fly, crash - repeat" is the RC flight mantra after all.

There certainly is an issue with the yaw servo control - effectively it was thrashing constantly and to some extent I think the FC was so confused it had little capability to allow control of Throttle or elevator.

I must confess to be considering walking away from the idea and just enjoying to robustness of my first build 250mm which now just works.

As you can see I've been busy!



I've even pretty much got the top cage patched together!  It needs reinforcing though.  

I will say the low quality of the supplied screws means the next big hit it take will probably ground it for longer as I'll have to source all new hardware for some of the hex head screws.

Anyway, the Loctite on the tail retainer needs to set, I need to reinforce the upper cage and remount the GPS and then I'll plug in and have a tinker with FC firmware and start proceeding towards another test flight.

Bad news. A few components on the Receiver were crushed in the crash and while looking complete they're not intact. This includes on of the choke coils under a heap of resin and a few capacitors.

The RX wouldn't even power up.

Which leads me to the FC, it does power up with USB but there's some charring on the regulator or transistor right next to the USB port. I'm going to presume that this feeds the 5v supply for parts of the board because the power for the RX is flakey. At a guess we had a short circuit during the crash and let some magic smoke out.

So I've ordered a replacement SPRF3EVO AND a SPRF3 Deluxe from myrcmart.com.

While I can probably repair the EVO by reading the part number off the EVO in my 210mm I think a fresh board is a safer bet for now.

The Turnigy iA6C receiver is able the only one that will fit neatly on this build, and give battery telemetry. There's not enough stack height for an X6B receiver unless I use the extensions on the cage. Maybe that's not a bad idea?

Otherwise it's a choice between AUD20 (iA6C) from hobbyking or AUD15 from Banggood for the X6B

So at 3am I jumped on hobbykings site and ordered two X6B's for AUD10 each with the token AUD6 next day delivery.

I'll take the iA6C (replace with X6B) from my 250 and use in the Trifecta and have a X6B and SPF3Deluxe for my next build!
