It the blades were undamaged then it's probably not the main shaft, nine times out of ten the feathering shaft would bend before the main shaft anyway (so it's worth checking the feathering shaft). A bent tail shaft is a possibility but usually you can see it when you turn the blades. If you...

Good post Randy! Biplanes can be fun because they usually have low wing loading, couple that with their relatively short wings makes them 'turn on a sixpence'. Wing loading plays a big role in the way a plane flies. 3D models trend to be built very light with lots of wing area making them...

I dont own an iKon but virtually all FBL controllers (except Align 3GX) dont use swash mixing in the Tx, you just set to 'single servo' Setting up a FBL is just about being systematic and following the instructions: Do all the swash servos move in the correct direction to Tx input? Have you...

+1, it looks like it hit the ground pretty hard. The steel in these shafts is (or at least should be) hardened, so it won't stretch/bend much before it breaks.

Your right Phil, the wire lengths and routing are optimised for a FBL with 'end entry' rather than 'top entry' like the Axon or Spirit. Fortunately for me the Vbar has end entry servo connections in the main processor unit, so it all worked quite neatly. I'm sure you will figure out a neat...

I dont have 0% throttle on any of my flight modes (except throttle hold), far too great a risk of accidentally selecting that flight mode when you are flying and finding yourself in an emergency auto! If you wanted a failsafe throttle kill then it's easy to set a mix from some out of the way...

That looks like a pretty good option Phil. I managed to install the Vbar in the forward position without any extension leads but the end orientated connections helped. Today's good news.. i think I've sorted out the spare parts for my repairs. I've found someone selling a new unflown 700X...

I hate extension leads and try to avoid them whenever possible. If the edge mount really does work out best for wire routing (and that orientation is supported in the software) then it would be relatively easy to make an 'L' shape bracket from a bit of aluminium or similar that would allow the...

Nice! As you know I have a 600 Pro but it's been upgraded through the years to the same spec as the Dominator, plus a few of my own customisations. I got mine originally as an assembled but unflown airframe, so I didn't have the pleasure of the full 'build from a box of bits' experience. One...

Phil, If the wires reach then perhaps option #2 is the best compromise? I'm not so keen on standing it on it's end as it might be difficult to make secure, the very last thing you want is the FBL unit coming loose and flopping about, that will spoil your day for sure. My Vbar is a bit different...

More videos as promised: 2nd flight - all seemed to be perfect at this point: Wobbly spoolup on third flight attempt:

Truth is Phil that with bullets you do need to constantly be careful of cross connection, they aren't inherently safe in the same way two pole connectors are. One thing (once you have swapped to alternate polarity); when connecting series batteries up on the helis always connect the wires from...

Yes, on many two pole connectors like Deans, XT-60 or the Supra x they have both + and - connectors on the battery 'same sex'. The plasic case of the connector will in such cases be designed so that you can't accidentally connect in reverse polarity. Usually with bullets they would be wired...

Phil, the connectors in the picture are two pole type, so you need a link wire. With single pole bullets usually the positive of one battery would simply connect direct to the negative of the other. I can see from your photo that the wires are long enough to do that without an extension. Sorry...

Phil, those Supra X connectors look great. Only thing i'm curious about is why the need for extra wire on the series connection between batteries.. Is that because the connectors on the batteries cant be couple directly? (they can with normal bullets)

Phil, some things that may save you some time that i learned from my two flights : If you wire up the motor with matching colours on ESC and motor it should spin in the correct direction (or at least mine did). ESC timing was left default (15 degrees), this worked fine I set the Governor to...

Maiden flight: https://youtu.be/lFZ6RdlsUIc Second flight to follow

'capacitor bank' was perhaps too grand a title. The reality it is just two 4700uf 10v electrolytic capacitors wired up to a short servo extension cable which connects to a spare port on the FBL. This helps dampen out momentary dips or surges in voltage. Mikado did lots of testing which showed...

First think I thought of was the tail pitch rod coming disconnected but I'd checked it before the flight and all was secure. Ball links were all connected after the crash except for the main rotor pitch links which popped off as result of the crash. The link on the tail control arm was still...

Rodney, Between flight #2 and the fatal third flight I didn't adjust anything at all. All I did was give it a good look over for any loose screws etc. (there were none).
