Currently I'm using a Summit 120HV ESC (waiting for Castle 160 to be in stock). With 24x8 it's barely pulling 100A WOT and power is quite good. New wing lock system is VERY convenient, if I were removing stabs I'm sure I would be excited about that as well. The color scheme is stunning, every person that saw it commented. Looking forward to more flights!
Congrats on the maiden. Looks stunning. If I hadn't bought the 85 Edge this year I would have had this one. I have the Xpwr 60 in the Edge and also run a 24" prop. I have the 24 x 10 Falcon Carbon C2E and in flight I rarely see 100 amps WOT. I would think a higher pitch would give you a lot more performance as 160kv is quite low, the Xpwr having 200kv. Better suited might be a 24 x 12 to make more use of the low kv of the GA6000.

Lovely plane, wish you many more awesome flights.

85" Extreme Flight Planes


Perfect day out today flying our Extreme Flight 85" planes. I have the Edge with a DA-50. Jeff has the new Slick with a GP-61 and Chris's Extra has a DLE-55 rear exhaust.

Great flight Jase. And as I'm building that same plane I'm curious, I know a lot of guys are building them Pull/Pull Rudder. But I thought I noticed a Push/Pull rudder setup in that one. I'm planning to run a pitts muffler on a GP61, and (oh my goodness) a 24oz fuel tank. If you John or Tim have a opinion about my setup what would you guys recommend for rudder servo placement? I'm thinking Push/Pull, but nearly everyone has more experience than I do at these setups.

Just got my new tube of Hysol yesterday (McMaster-Carr) and I'm really getting excited about this one. Too bad winter is getting so close.

FWIW - my setup is electric (Dualsky GA6000 - 1194g) and I put the rudder servo (HV777+) in the rear. It balances well but I do have my batteries pretty far forward. I suspect I could have done pull-pull and still balanced OK with the batteries in the over the wing tube tray? There is a lot of flexibility in placement.

Thanks Chris! I may have to give the 85 Edge a try as well when back in stock. So far this Slick is my absolute favorite 8X" inch plane. The 160kv GA6000 is doing very well even with 24x8 (which is all I had around in gas thickness, which the GA6000 is made for). It stays very cool and seems to be running very efficient (good flight times). Recall that the Hacker A60-18L that was the standard for the 87" SHP was a 149kv, I loved 25" props on that one and enjoyed the feel of the big disk. I will try higher pitch 24" props soon but suspect I will end up 25" again. I'm currently up to 23x10 on my GA4000 85" Extra and 87" SHP, I had to switch to Castle 120HV ESC to overcome the sync issues I was having with the Summit 120HV even at 23x8 (a bit surprising). The Summit is currently doing well with the GA6000 and it would be nice to not require a larger ESC.

If the 85 Slick is as good as my 74 size Slick then it is awesome. The 74 is simply the best mannered plane I have ever owned so I bet the 85 is just as good.

I think it's interesting that Dualsky still say "no electric props" on their GA6000 motor. My Xpwr 60 is using Falco carbon electric props with no issue and I have the Mega Bushmaster with one of Aeroplayin's StinGr drives in it driving a 28 x 10 electric prop. That is mounted like the GA 6000 with a 4 bolt hub and again no issues. Plenty of guys out there using both Carbon and wooden electric props in all sizes. I would have no issue running an Electric prop on a GA6000 if I had one. It may help with your sync issues with a lighter prop allowing a bigger pitch/diameter for more thrust. Less amps for the same size too and less mass to accelerate giving your ESC an easier time.

The issue is that the shaft isn't threaded far enough to hold a thinner electric prop. When tightened as far as the nut can go, it still is not holding the prop. It's possible a spinner backplate might add enough thickness to allow electric props, I plan to give that a try eventually (*that* might finally be enough reason for me to use a spinner ). I just happened to have 24x8 GAS prop I could use. The sync issues I have on the GA4000 are using larger props than recommended, a 23x10 works well using Castle 120HV but the Summit lost sync sometimes even with 23x8. The Summit ESC is working great so far with the GA6000.

Bottom line, yes the 85 Slick is awesome. I've been flying it near constantly since getting it.

Congrats JFV!! - GA4000 vs GA6000

Congratulations JFV on your beautiful 85" Slick!! Can you please share how is the performance between your 85" Slick w GA6000.9, and 85" Extra w GA 4000.7? It may not be apples to apples comparison, but I'm trying to understand between GA6000 and GA4000 if one is more suitable than the other on similar 85" airplanes. I got the GA6000.9 for my new EF 85" Extra, but now wondering if GA4000 would be a better choice - looks like you have experience with both. Thanks in advance.

Either is a good choice IMO. The GA4000 is good power for this size (I have it in both the 85" Extra and my vintage 87" SHP). But, it's not the kind of extreme power that some seem to want these days. I tried pushing it with larger props (23" and 24") but the Summit ESC would lose timing. Most recently I switched to Castle ESC in the 85" Extra and am able to run 23x10 well. So far, the GA6000 has been excellent and I'm only running a 24x8 (will try 24x12 soon). I purposely choose lower kv as I like the larger props. I may move up to 25x8 or 25x10 eventually on the GA6000. The Slick seems to handle the added motor weight very well and the motor runs efficiently. I assume the 6000 can be pushed to ballistic power levels if desired but currently I'm running the Summit 120HV so keeping the amps well below 120. That said, I'm very happy with the power even at 24x8.

Bottom line, if you have the 6000 already I'd just stick with it and prop appropriately. You likely want rudder servo in the rear.

I used almost every electric prop on my GA6000-160 KV with 14 S and single centric screw. They work, I had like over 1000 flights.

Falcon 24x10 c2e
Falcon 24x13 c2e
Falcon 25,5x13 c2e
Mejzlik 24x10 EL
Xoar 24x10 pjn
Xoar 24x13 cfk E
Xoar 24x12 pjn (my favorite 24 prop)
Xoar 25x12 pjn (my favorite 25 prop)
Fiala 24x12 e3
Fiala 25x12
They work perfectly well if KV and cells are matching. My Dualsky GA6000 160kv, 14S has like 130 Amps on some props. HW200.

But now I am changing everything to the StinGR85 as I have one minute more compared to a rewound GA6000.
