I fly mine with 14x6 for about 1000 wt total, most people go for 15x6, about 1200 wt. The nice part about it is, you can double these 4s batteries for an 8s setup on a 65-72 plane for about 2kwt total. I'm going to go 5s (or 6s.. not sure) with the EF Edge, though.
I know what you guys are saying, but!!!!!! I got to fly this little gem, and IMO you NEED to go with the recommended setup... When I was hanging out with Chris we talked allot about setup and tuning, and that's a big concern of His.. That allot of people will never experience the full potential of his planes because they don't get setup properly...

One of the big advantages of 6cell with a 14x7 or 15x8 is that you can pull crazy watts with very low amp draw! Something like 1300watts and 50 amps, WO!!!

I'm swinging a 16x8 on 5cell that produces 1000w and 60amp


Like I always say "you can put a bigblock in a VW beetle" "but that dosent make it right"

Yea.. I have finnaly figured that out.. When I started. I was like MAN.. This thing is pulling like 80 amps.. SKORE... Chris was telling me that was very inefficient... I will be running 6S on this.. FOR sure..

Perhaps Chris could post some general guidelines - weight of the motor/ESC, prop size, watts. It does't matter all that much how you get the watts, as long as your setup is efficient and can take voltage/current. Obviously, the less current you have, the easier it is to have an efficient setup, so on average high voltage is better. Still if you already have 4s batteries that can take 80A - e.g., 4 A*H 25C - a 4s setup may make sense.

i completely agree with you that 6s is the most practical and best option, but i was just pointing out that other similar sized planes run on 4s fine. sorry, i really didnt mean to start a huge debate

If someone wants to go 6s on their edge I've got a NIB Scorpion 4020-16 for sale. They're good for up to 1500 watts. Make me an offer.

No... It's not like that.. From time to time we have these discussions, and I'm not saying anyone is wrong.. I've done many modifications to my planes, that I wouldn't recommend to the masses...

Hey Tim so are you going with a 5S setup on the edge?

I'm swinging a 16x8 on 5cell that produces 1000w and 60amp

I do think the "trend" is higher voltages make for easier higher efficiencies.The availability of he higher S packs at more decent prices are making this a reality.I think back about 3 years and we were trying to pull all the power we could from a 3s pack lolol.So we can fly these planes light and powerfull.I believe this is a trend to go higher voltages.It is a philosophy being used now by lots of folk in the RC industry.Kinda makes sense too.My "plane setup" philosophy is to try to get an equal amount of balance between motor weight/power to battery weight/power.I dont like to add weight to my planes.CG makes these planes.If you can get a great CG for your flying preference for the plane you are flying without making the plane too heavy or too light,you are in the game.keeping temps down and power up is the new cool tho it seems .

Yes, I have the 5cell (3600 35-45C) setup in my 58" with the recommended torque motor, and a 16x8 Xoar.. 5cell is the light setup for this plane..


(this is from page one of the thread)

"Extreme Flight, We've done a lot of experimenting with this power system and various batteries and props. Here are some interesting details using the 4016/500 and Airboss Elite 80 Amp ESC:

16x8 XOAR on 5S TP 3850 mah~1100 Watts at 65 Amps

16x10 XOAR on 5S TP 3850 mah~1300 Watts at 73 Amps

15x6 XOAR on 6S Turnigy Nanotech 3000 mah~1250 Watts at only 53 Amps!!!!

15x8 XOAR ON 6S Turnigy Nanotech 3000 mah~1400 Watts at 71 Amps."

I have some 5cells may get a couple of 6S to try it out.

What type of flight times are you getting on the extra with that set up.

Im reading all the suggestions on batteries, I have the combo pack on order but I don't want a plane that is crazy on power and to much for me to handle. It looks like the 6s will do this, Herc says it feels like it has to much power on 5S, so what would the suggestions be?

5cell, and prop down if you feel like it's to much...



I flew one pack, with my 58" this morning before the teams showed up and I had to leave the ballfield..
Now I'm sitting in front of a local club waiting for a member to show up and open the gate... I wana fly!!!!!

How do you figure a 5S setup has less power than a 6S.
