You must be extremely good at throttle management. I was flying my 60+ amp max static 5S 4000 planes today and was only getting 7 1/2 minute flight times. Even with 5000mah if I was pulling 100+ amp burst my flights would be about 5 minutes and the motor and esc would probably be nearly on fire when I landed. If it works for you though more power to you. That means you can fly planes this size using a very inexpensive power system and not have to deal with doubling up packs for 8S. I'm afraid with my undisciplined left thumb I'd melt the whole thing down within a few flights.

Thanks,

Sean

If you want to fly around WOT sure this isn't the setup for you. This is a 3d setup WOT runs are short. This motor with a smaller diameter prop on 8s would be great for sport or IMAC.

That's not to say the don't fly great because they do and there's plenty of video and satisfied customers around here to prove it. I also noticed it seems like a number of people are putting 8S in them these days. IMHO 7S or 8S i a more natural match when pairing the Slick with an outrunner power system. I'm sure it stays nice and cool and keeps the amps down so flight times aren't too short. All that said though the numbers you've mentioned below are very good. If you're hovering at under half stick throughout your flight and after 8 minutes you're only down 70% on a battery that's nice performance and reasonable flight times. What motor/esc are you using?

Thanks!
Sean, I'm not sure what setup you've seen, but the 9 lbs Slick works great with the 6S 5000 setup. If you watch Andrew's video, then you should know that he likes to keep his power level close to what a scaled up 150cc version would be.

There are TONS of people running this setup on their Slicks, and they have all worked great.

The only difference b/t 6S 5000 to 8S 4000 is whether or not you want to double up to make a 12S (50cc conversion) setup, or halve it to power the 55-57" planes.

To be honest, I rarely ever use WOT and yet I was still only getting approx. 7 1/2 minute flight times yesterday. Not saying you don't have a great setup because you do and it obviously works great for you. For me, I need more cells. haha

Hi BoneDoc,
Yes, I've seen the AJ videos and of course they are amazing and it's quite obvious how good the 70" Slick can fly on 6S, I'm not challenging that in the least. I personally think 7S or 8S is optimal if you're using an outrunner to power a plane this size though. Even if these motors can handle brief periods of use far in excess of their max current ratings that doesn't mean they don't become very inefficient at those levels and lose a lot of power and potential run time to heat. Again, I know people are using 6S and love it and they should continue to use it. Personally, I'd spend a few bucks more and set it up for 8S 4000 because I think that would be the right setup for me. No one loses here because the 70" Slick and presumably the yet to be released 70" Extremeflight Extra (sorry I didn't intend to turn this into a Slick thread) are versatile and can work with a multitude of power systems.

Thanks guys,

Sean

I think either setup works well. I intend to go 8S on this plane.

Again,

What I'm challenging is the fallacy that you need higher cell count to power these birds (be it EF / 3DHS).

If you do the math, the total energy delivered / available on an 8S 4000 equals the energy on a 6S 5300. One delivers it through higher amperage, while the other through higher voltage. Each works just as well, and produce just as much power. IMHO, the decision should be based on whether or not you have aspirations for bigger birds (like the EF 88" Edge, Extra, or Yak), or smaller (like the EF 58" Extra). Bigger packs will have less resistance, as well as a higher rated ESC (like the ICE 100). And again, an outrunner with a hotter wind (to take advantage of the lower voltage of the 6S with a higher KV) will have LESS resistance as well.

I've just found through personal experience that higher cell count generally gives me more power and cooler running components than propping up and pushing tons of amps(of course that's a generalization and there are a lot of variables that come into the equation). So long as a motor can handle lots of amps then yes you get more power by raising the amperage. You certainly get more input power with higher amps but I would have to think efficiency starts to suffer at a certain point doesn't it? Also, I never said you need 8S to fly this plane. We are in agreement that 9lb Extremeflight or 3DHS 70" planes will fly on 6S or 8S and people will probably be happy with the results either way. I personally think it would run cooler, a little longer, and have a bit more punch on 8S but there is no question it will fly on 6S. Hey, in the end maybe it's not enough of a difference to matter to anyone other than me so I'll keep quiet now. I'm just looking forward to seeing some video of the plane in action no matter what the power system.

Thanks,

Sean

Stay tuned to Extreme Flight there is more in the works that is so awesome. In fact, there was a little leak at the XFC over the weekend. (Take a look at RJ Gritter's plane!!!)
