I reckon this one would be worth a try as it has active free wheeling

I use these in my big Yaks, I think it's the earlier version tho

you'll also need one of these. I use one in the HK 72" Yak. The Other Yak, the yellow one from super and cheaper has a dualsky twin regulator and twin battery system. You can also put two megga 8's together with two lipo packs for extra bullet proof reliability but it's not needed.

and I also use one of these, it lets me know not only that the radio link is on but also the pack voltage, which is a handy safety feature. I like to run a seperate pack for the radio link that way you still have controll if you loose motor power and it also supplies your reciever from a nice noise free source. (the motor and ESC can be pretty electrically noisy when you get up to these voltages and you dont want to connect your reciever to the same power source as all the noisy stuff)

and you will need one of these as well to power your BEC so that it can power your reciever and servos

I use a switch harnes between the 2s lipo and the BEC

Here's a switch with a voltage display built in, looks a little heavy have to check the weights verses them seperatly

Just some suggestions This is the way I've set my machines up and they have been good, safe and reliable so far. I also use FRsky for the radio link which is a super reliable system.
