FYI on the GR-60:

Watt metered it last night with a Turnigy Plush 80a, 15x7, Turnigy 4s-3600 30C

1 sec burst
97.3A
15.6V
1513W
I didn't want to sustain that for 10 secs because I pulled so hard. The power on the bench is tremendous. Haven't weighed it either so I don't know my power to weight, but I didn't do anything non-typical so I expect standard weight. Killer power though, can't wait to fly it. I might need to prop down. I will try it on a 14X8.

For control throw setup and CG, I went straight out of the manual.

As far as the power system, lots of guys have Torque 4014 motors left over from their SHP, Yaks, Katanas, etc, that they flew on 5S. That what I've got in mine, and dropping to 4s didn't hurt it a bit.

In fact, I've still got just a little too much power because the new Pro Power batteries have a lot more punch than my 4s Extreme V2 packs. I think I can get around that by working on my throttle control and trying to inprove that. I might also try 30% expo on my throttle channel.

I've become a believer in lower power systems. The 4014 on 5s was just stupidly overpowered. It was so much power that you not only couldn't use it, but it was hard to modulate and control. I am much happier flying the SC on 4s than I ever was flying the SHP on 5S. At the time I just didn't know any better.

I'm not afraid of high powered planes at all. In fact, I used to race Formula One, so I like a badass plane. For 3D, though, too much power hurts your ability to keep the airplane in a post stall attitude. It's too easy to blast off when you are overpowered.

This isn't my idea either. I got this from Andrew Jesky, and since he's the man, I figured I had better give it a try. I think it's made a better pilot out of me. It's certainly made things much easier.


For those who haven't been to the blog lately...........

Doc,this i think is one of the smoothest flights ive seen you do.This is a compliment and im not slaming your balls to the walls previous vids either..i still dont know how you get away with what you do with thos planes lolol.But the SC looked rock solid and good stick work by the pilot.i really think you should move to the cochran ga area soon.

Thanks, Manta. I can always count on you for something positive.

However, check out vid #4 because it is the smoothest of this batch.

Oh, that's ok. I'm sure those people will show up eventually.

Well, it is. The lighter weight makes the plane easier to fly slower, and also more agile and stable at those lower speeds. Everything just slows right down and there is more time to deal with everything.

Comparing that to my SHP videos, the really big difference is the power-to-weight ratio between those planes. The SC is much, much more manageable with the 4s power. 5s was just too stupid much overkill...way, way, way too much....much more than you could even use.

Looking back, by comparison, I think I was just hanging on with the SHP, and now I'm flying the SC. I feel much more in control, and much more confident. The SC almost feels like a 47" SHP in how easy it is to toss about, but it retains the SHP's big plane feel without the overbearing awesome power.

Of course, I was pretty confident and at ease with the SHP, but at the time, I just didn't know any better that lower power actually gives you more control. I always thought more power was more to get out of trouble with, and it was. More power, especially too much power, makes staying in post-stall flight much more difficult. The whole idea of 3D is to slow the plane down, and more power works against that.

And I think that's where the SC came from. I think the SC is just the lightweight 130-170wpp philosophy grafted on to the SHP. The SC is not a completely new plane....it just flies completely different.

Is 15x7 pulling 97 Amps too much prop for the GR-60??? Max amps on the website says 80 A!! I guess I can run it and see if it gets hot.

I met up with Hypersprint and Charles Allen at the Parrish club and put a few more flights on my new SC. I wasn't on my game at all and didn't give the plane a very good ride, but at least I didn't hurt it and I did enjoy hanging out with the guys.

I borrowed Earnie's (the club president) plane for the full contact combat and scored a full tilt kill, unfortunately on one of the nicest dudes in the club! Of course, killing the other guy is what you're supposed to do, so we all had a good laugh over it.

Next Thursday will be the last Parrish Thursday Cool Guys Throwdown with cookout, Combat, and Night Flying until daylight savings time returns in the spring, so I hope to make it down there.

I flew pretty badly today, so it's a good thing I held back one decent SC video.........

That just doesn't seem correct to me but I could be wrong. I run a 15x8 prop on my Reaper 60s with Airboss 80 ESC and have never seen the amps that high.

I wonder if there is a problem with your watt meter? Which one are you using?

basically the same as the "Wattsup" meter

I took two readings. It was very clearly 97 amps, 15.6v, and 1513W

I have a turnigy plush 80A. It does not have the auto-timing feature like the Airboss, which is plug and go, so to make it sync at WOT I had to change to timing to HIGH. I contacted Scott and he said to prop down and the timing was giving me high numbers.

It definitely sounds like you need to prop down, but I'd be more worried about the ESC myself. It seems like there would be a good possibility of it frying pretty quick pushing that much current!
