Sure here is post from my build thread:

Outlaw Update
Been really ringing out my Outlaw and the new Hyperion Z motors are awesome setup.
the evolution of my Outlaw has shown the need to insure no vibration at high rpms and summer heat temps allow the bell housing to flex. My cures to date is running the new 3020 Zs motors and a custom X mount of aluminum in which I can add an additional bearing in the mount, by stacking two together the added bearing is almost .750" away from motor back. As an added bonus it is heat sinking heat out of the motor and the mount is warmer than bell.
My current setup is:
Hyperion Zs 3020 8 1135KV
Exceed Momentum 100 amps ESC
Graupner G-force 9X8 prop
6s Lipo 30C 5000MAH
20.8VDC, 102amps, 2146watts 21700 rpms
Dans Outlaw in the video was Scorpion and is now Hyperion setup as the Scorpion motor does not allow for a bell mount prop shaft and ends up knocking magnets loose. The Hyperion shaft comes pressed into bell and is oriented to backplate mount allow a simple bolt up to my X mounts and additional bearing.
Dans Setup: (IE he likes the noise)
Hyperion Zs 3025 6 1287Kv
HobbyKing ?? 100 ESC
Graupner Nitro prop 9X5
6S Lipo 5000MAH
20.7VDC 110 amps, 2331watts ??? Rpms
I've simplified an E conversion to a simple carbon hatch cowling mod, takes less than an hour.
I am selling the X mounts blanks or drilled for Hyperion with bearing installed
Carbon cowling with carbon tab
The pyle drivers and flat spins WOT are nutz. I put a velcro strap across the bay to insure the battery stays forward, removal requires it to go almost 2" rearward to get it out thus the velcro to itself acts as a wall spanned across ribs.

RE: BEST DELTA EVER! Post your deltas
Cool, thanks c/f. Thgat's a big honking battery pack! To think I was fussing about the weight of a 4s 3700, which I don't own yet, only 3s.
Obviously when you go looking for 2kw, 11.1V is a little impractical without copper barstock for wiring..

I have actually peaked my 3.8 oz inrunner at 1300+ watts with my 15.5 oz 4S 4000mAh battery and they still work. A little less prop but the 34,000 rpm makes up for part of it.

RE: BEST DELTA EVER! Post your deltas
I agree Mike - I ended up thinking the biggest I would use is a 4S 3700 or something of that weight. I think 1200-1500W into an SD would result in some pretty strong performance. My lekkie SD that is slowly coming together will peak at around 1kw and probably fine at sustained 800-850W, so I am not excpecting blistering speed but it should be a nice quick sport flier.

RE: BEST DELTA EVER! Post your deltas
I am amazed that at near 4lbs, to launch this 36" Delta all I do is hold on to the Vertical fin and power up to 2/3 throttle at a 45 deg angle and just release, The thrust is amazing, I remember my nitro days trying to launch a DD with OPS 45 RE marine and it was a gamble. launding is also a non event, will do a 3 point full flare to stall.
My flying bud even tried an 8X6 APC nitro prop on his E-Outlaw at 2400W and it too launches straight away, same technique so even a 8" diameter at these wattages are a non event at launch.
I would have no reservations of putting this kind of watts in a SD, as the powerplant definately can get it out of the hole shot.
Remember the ole Whiplash needing a catapult??

I am sure a SD would fly with your setup but a large battery compartment would have to be built on top of the 6% wing. Also an inrunner clam shell mount would be simpler as there is no firewall. I have seen an outrunner installed on a SD so it can be done but I never seen that big of a battery in one. Your setup would definitely provide the necessary thrust. [X(]

RE: BEST DELTA EVER! Post your deltas
I may have exceeded the limits but will know this weekend. My Outlaw with the Jett .40QM is ready to go
I was mostly concerned about weight and balance however these turned out to be none issues. The Jett is 2 grams heavier than the OS .32 and I put a bladder type tank in....I have an APC Carbon 7.4 X7.6 prop (same as I have on the Demon with the Nelson engine).
Update - We will have the fiberglassed Demon with the OS .46DF ready by Thanksgiving and are in the process of looking at an electric solution for insane speeds. The biggest problem always comes back to the batteries?? [] Any ideas out there?
Blue Skies,
Jim

I just lost my BTE Vortex, slow but hadled very nice.
So now I have a .91 OS with tuned pipe sitting on the shelf, also a .61 Rossi with rear exhaust and pipe.
And I want something faster, what's available for those sizes?
Something like the Robbe Delmo would be great, they are just hard to find
