v tail mixers

just wandering which ones will allow the speed controller BEC to reach the receiver as the ones im using dont seem to let the power get the the receiver

I have one of those and although I haven't had BEC issues it did give me failsafing issues.

lol that's odd cos my failsafes seem to work fine

Haha, why is it such a mystery!?

What if you bypass the v-tail mixer? Although it may need power to work. Alternatively you could have a dedicated battery pack for you Rx.

i just tested it again and it seems to be working but it originally didn't want to when i tested it before but if i put it going forward and the reverse suddenly the power to the receiver cuts out but it works fine if i use a receiver battery

Interesting, I was having an issue where there was a massive delay between fwd and rev, I wonder if what's happening is the Rx is cutting out?

I have since bought a GWS mixer, so I'll let you know how I get on.

i thinking there isn't enough power available from the battery so it cuts the bec power so i either need a lipo battery or i need to use a battery for the receiver and put a switch in somewhere

i have just thought of something else that might work if i fit a capacitor in it will store some charge and then when it cuts the power it might last long enough till the main power comes back

the cap did improve it a bit i think the uf rating was to low or i need to try it on the rx side of the bec

I'd start by eliminating what components it could be.
The ESCs could have unreliable BECs, try running without the v-tail, then with a seperate battery pack, etc....

Those el-cheapo v-tail mixers also have very long leads, could be shear distance of the thin wiring.

We are using the BEC from one of the 85a Botbitz ESCs, powering a R6M receiver (one that comes with the Planet 5 set) through a v-tail mixer (this one) without any problems at all. Failsafes perfectly and doesn't have any fwd/rev delay issues. :)
