@Rob Cherry,
The prototype 516s look like they're using standard MKS servo arms on cyclic.
Is the cyclic setup compatible with the CF arms that Matt includes in the kits for the bigger helis?

No the CF arms are 20mm and the recommendation for the 516 is 13.5-15mm depending on your setup. 15 is the go to.

Xnova have posted specs for the Xnova 4020-1350kv motor.

Claimed is:
max continuous power 2500w, peak power 3200w
max continuous current 125A, peak current not listed
weight 340g

That's a lot of mumbo!
Enough for me to opt for a hobbywing platinum 120a V4 ESC over the 100a V3 that I was planning to use.
Weight of both ESCs is similar and I expect the 120 will be able to handle the expected current, can mount a fan if it gets too warm.

Guys I'm going to use my e5 motor 4025-1100 with 5mm shaft, thanks Rob) should I use the talon 90 it in my whopper or I have brand new cc 120?

Talon 90 is plenty. Castle 120 would just add more weight and you'd need a BEC.

Thanks Chris, forgot about the bec

[Cliff Chmiel]

will the bk ds 5001 fit or the 3001 ? any one know who has a sale on servos?

If u run the Talon90 and gear it properly.. so that the gov is optimized at 100%’ish... u’ll be fine. Matt has a variety of pinions available to accommodate different desired headspeeds. This is the best way to set ur machine efficiently and keep amperage & heat in check. U can however opt for a fan to help with heat if u so choose w the Talon90. I used a fan from Tekin designed for their RX8 ESC used in 1/8th scale buggies. Just use the short screws that typically comes w servos for mounting and line it up with the grooves of the Talon’s heat sink. Power it off ur RX... my particular fan is a 5v, but I’m running 8v thru my system and so far it’s fine. All this said, proper gearing is the way to go on any setup imo. Check the Synergy store for ur pinion of choice!

I'm using the servo arms that came with my Kingmax servos, which all have spacing of either 13 or 16mm. The Brain 2 I'm using is happy with 16mm.
