Wiring up 5th scale with dual servos

[MisterK71]

Hey All, Finally got to take my FIveT out for practice this weekend and had a freaking blast, only issue I had was I smoked one of my servos for steering in about 15 minutes of run time, dual set up, ran a single the rest of the night. Pretty sure it had to do with running the second servo on an Aux channel and adjusting steering trim and not the aux at the same time... my bad. Anyone have recommendations on wiring up this set up that would avoid this issue? Dual steering, single throttle/brake. Really just want it to be bullet proof, not sure a Y harness can handle the draw?

I have a y harness on my 5ive B running 2 hitek 845's. Have not had any issues yet.

Ohhhh pretty. They look so nice before you run them, LOL. I will give the Y harness a try and see how that goes, thanks!

The harness from the MTXL is probably your best bet.

I use this on my mcd`s 3x hitec`s running 7.4v lipo....http://www.feetechrc.com/product/el...power-supply-connector-with-bec-x-4-fe-dpc-4/

I got another one here to go on me 5ive

 

[Whoduh]

Lol.
Its been run. Just kept it clean.

 

[evssv]

same as my 5ive....

I'm running three Hitec servos, can you kind of explain how that would set up?

Not 100% sure I understand how/what this does, can you explain a bit more please?

Where do you run it to keep it clean? Your garage?

ok...so u connwct the rx lipo to this lead...and then 1-2-3-4 servos have direct power from the lipo with out going through the rx....basically..if u Google it u can see a diagram of how it works

Does this unit in turn plug into the RX then? Is this a kind of voltage regulator to stop from frying the RX?

 

[evssv]

which is what the mtxl lead dose aswell

yes....servos plug into the lead....which then plugs into rhe rx as normal....but there's no power going to the servos from the rx's servo ports.....make sense

 

[evssv]

yes this way u take all the strain off the tiny rx circuitry by by passing the servo power bits...so ur running all 3x direct from the lipo

You're awesome, SOOooo, what would be the benefit of running either of these options? Seems like the MTXL set up is a lot less burdensome, the BEC 4 unit must have some extra benefit??

 

[evssv]

bec is the best one imo...but both do the same tbh

Thanks for your advice, I appreciate it!!! Still learning about these big bad 5th scales!

 

[evssv]

no probs dude so am i tbh
