3DHS 60" Yak-55

[gyro]

+1, though 3dhs 60'' birds are setup around a 4-cell pack. so you would want the 714kv wind. I am going to try one of those Geckos next time I need an esc.

Yes.... BUT... They work just fine on a 6s3300. Check out Brian's flight on 6s3300:

Not sure about the edge, but I know the 57'' extra battery tray is fairly weak. I am certain it would not support the extra weight of a 6-cell pack. I am hoping they are improving the motorbox and battery tray on the 60'' yak.

Good point. I hadn't factored that in.

I've also begun reinforcing the battery trays of my electrics so that's a possible solution.

....if you run a 6s2600, it would be the same weight as a 4s4000 (or very very close)

Would hs 7954sh servos be to much? Also, would this plane be better on 4s or 6s?

Yes, they're too much, and way to big.
You'd need mini size servos, and the Hitec HS-7245MH are about the best all around that are available.

6s is more efficient, and can produce a little more power (watts) at the same or lower motor temps.

What c rating is the best for this size of plane? Has anyone considered running it on 5s?

[MENTION=2684]AMO FOCO[/MENTION], I use 35-40C with no problems. I usually fly 6 minutes and batteries are just warm to the touch. I don't measure actual temp.

7954's are too big, but mks and bk servos have some servos that are absolutely killer in this size range(I'm going with bk's for my 57, they have 147 oz torque, .03s). Right now I'm still trying to work out what I want for a power set up, because it's too much power in my opinion on 6s on the torque motor, I'll be going either 4s on the hacker a40-10s or the motrofly(don't know the model #)

I run the BKs in my 60 laser. Cody runs a RJX servo that is slightly slower (like .06) and has more torque and seems to hold up better to being used in a airplane. They are all around the $100 price point. They also weight .5 ounces more each. I like 7245MHs and I will probably use these next time I do up a 60" plane.

You can never have enough power. Motrolfly 4315-480 is apparently the way to go.
