A hi power 6S setup is IMO the best setup for this jet.
Good to know regarding the 5000 or the 4000mah 7s pack. Like you, I was thinking the 4000mah is a good trade off, plus its probably not bad to cut the run time by about 1 min especially if your running a maxed out stock setup.

Which 7s pack did you go with?

Zippy 45C 5000s and GenAce 60-120C 4000s.
With the GAs 4 minutes max flyingtime. One fast 4 minute flight didn't have enough juice left to taxi back to the pits so don't forget to set the timer!

Sounds good. I am looking at that particular Gens Ace 7s pack. I have been happy with the other 65-120C packs from them, all with very low resistance.

Good batteries for a good price.
I use 3S and 4S packs in series for 7S.
A single 7S pack limits my options for use in other airframes.:-)

My 25-50c 6s, 5000Mah nanos have just started to swell just slightly and I have noticed a slight drop in watts as well so it is time for replacement. What c rating are you all using. I am thinking of new lipos with a higher c rating, perhaps 45-90 nanos. We dont get nothing for nothing so the higher c rating means heavier batteries and I am hesitant to just add extra weight to my F4 unless there is a real benefit to do so. I beleave a higher c rating will also give me a small increase in wattage. what do you all think?

I've read a ton of these posts and sorry for asking but how does this F4 fly with the stock setup? If I were to get one should I immediately get different motors & fans?

It flies ok but sounds like a dentist drill. Using a Jetfan-80 or a Stumax SM80-45 instead will fix that problem.

Well, not a bad thing. I can close my eyes while @ the dentist and pretend I'm flying...

I was fortunate enough to watch Castel101 maiden his F-4 this weekend. We have a short runway and he successfully deployed his custom brake chute. Very cool! Check it out:

Hey Wisdumb nice flying and vid!

Did you use flaps and or brakes on your F4 or was that all chute stopping it?

Thanks,

Dennis

Castel101 bought the airframe from me and added all his magic touches and equipment. He was the one flying. He didn't use flaps on the maiden. I believe the chute really was the stopping force… you can see it pull the airframe to the right a little when it fully deploys.
I have to say all the talk on here about going to 8s, etc… this thing few beautifully on 6s and was very fast. Of course I wasn't the one flying, but it seemed to have plenty of power to spare from my perspective.

Ask Castel101, he is the designer of that mod. I know it uses a rubber band, a pin and a servo and works like a charm.
