Haven't bought anything yet, but here's my initial setup:

Scorpion 4025-12 (I have one to use, otherwise I would go with the ZS4025)
Phoenix 80
WR SuperMini BEC
Turnigy 5s 5000mAh
XOAR Sword 17x8 or 18x8
Not sure on servos yet.

I know everyone said 6s is better than 5s, but the scorpion calc shows the 17x8 pulling 75A and 1465W and the 18x8 pulling 87A and 1712W. Also, I have six 6s 5000mAh batts for my 89 Slick and those seem just a little big for the Samson. So I figured if I used 5s 5000mAh batts I can always parallel these up for my Slick to try out since the 6s setup is way too much power anyways. Any thoughts, should I stick with 6s and just get smaller cap packs to stay with weight limits and go with a lower kv motor like the ZS4025-16?

I prefer the Extreme Flight spinners over the Hyperions as they have an aluminum backplate and they come in black. But the MPI Aluminum spinners look even better.
Have you ordered any of these Maxx Products Spinners, Chris? I think that the 2 3/4" are the right size. Do these fit the Hyperion prop shaft? The nut has to thread on to attach the spinner.... says (1/4 inch 28 thread). What size is the prop nut on the Hyperion motor?

I have not yet as I need to put a bigger order together for them.

I need to check, but want to say it is 6mm.

Don't want to hijack this thread, but y'all seem to have the most info on the new Hyperion ZS motors.

Has anyone run the ZS 4025-16 on 8S maybe a 17x8 prop? I'm purchasing one for my 3DHS 70" Slick AUW 8.5-9 lbs and am hoping to get in the 1800 watt range with my 3700 25 C packs.

The prop data on the allerc.com site list a 16x10 APC at 71 amps and 2186 watts

Prop type #cells Volts Amps Watts RPM

APC 1510E 8S 31.08 59.5 1851 8168
APC 1610E 8S 30.62 71.4 2186 7748


Thanks for any info you can provide

Ron

Scratch that, 6mm motor shaft and 8mm for the prop shaft adapter.

Well, settled on some servos today. I ended up with Futaba 9551 low profile servos. They weigh 1.6oz ea and put out 120+ oz at 6volts. What servo arm lengths work for this plane? I'm thinking about 1.5" arms for the Ail/Elev and I have a SWB 2.5" double arm for the Rud.

I think I'm gonna give the scorpion 4025-12 a go with some 5s 3700mAh batt. If the 5s setup works then I'll get some larger cap 5s packs. Has anyone else tried a light motor/battery setup? I'm wondering if this combo will work with the CG???

I've decided to go Hyperion on everything..I really like the specs on the DS20-xTMD's. My friend went for the xSMD's for a Heli project. Will run 5S-5000's and the 14 turn ZS motor. At less than 10 oz. per sq. ft. wing loading, it should be fine, I'm anxious for the trial.

I did order some of those MPI Spinners 2.75 inch spinners as well as the 8mm prop nuts, so I will have a few in stock and will test to make sure it fits the Hyperion prop adapter.

maiden today

I maidened mine today using the reduced control throws listed earlier in this thread. Knife edge was fine using the reduced throws, as was landing. For tumble and inverted flat spin higher rates as listed in build manual will be required.
For those interested in lower $ and lower weight build, I used a Scorpion 4020/14 and TP 5S/5000 bat. with slightly over 1150 watts @ 70amps and APC 18X10 prop. Take off roll on a rough grass field was very short. Vertical performance is not impressive with this power setup. Most of my flying was at low throttle setting, so I think I'll try 18X8 prop and maybe get a higher prop speed and better vert performance.

17x8 on the Zs4025-16 with good 8S (maybe 4000-4200mAh) pack will be really excellent, imo. I've seen it fly with that setup and it is pretty impressive. The only drawback is the HV ESC needed. On the other hand, if you have a DUO or 2xNET chargers, you can SYNC charge 2s 4S packs faster than you can charge a single 6S pack (if the packs support high charge rates, like Hyperion G3 do....).

Batts will need to be all the way forward, and you may want to add some weight to the front edge of cowl for the fist flights. If 5000mAh+ 5S later, no weight should be needed.

Managed to damage mine on the weekend. I probably shouldn't have been flying in the wind I was flying in but hey you live and learn. Will post pic's of damage so others might learn later today. Damage appears to be confined to lower wing and body were one of the landing legs tried to rip out..

Note: going from 5s to 6s turned this thing from a fun scaled aerobatic plane into a 3d monster

EDIT: All fixed, now as soon as I find my camera cable I will upload pics. For those that asked I am running the Hyperion Z4025-14 turning a 19x8.

EDIT: found camera cable; http://www.rcgroups.com/forums/showt...1#post12947892

I've been thinking about putting Gorilla glue in the landing gear plate area on mine. (still under construction.) Now I know that I will. Do you think that would have helped with yours, Flyingrally?

Not really. I am a big fan of gorilla glue, but not so much these days in balsa planes. If you have a problem it is a bugger of a stuff to get off so you can get at the broken bits.

The design of the landing gear in this model is actually very good, although a big hit is a serious fix as it all ties back into the firewall and bottom wing front mount.

I think the current design will see damage to the wing happening when ever the gear is damaged, but I think in my case and probably others that this was/will be a good thing as it minimises damage to firewall and bottom wing front mounting area.

IMHO it doesn't need the gorilla glue.

I agree that the L/G plate is very robust. It is also hard to get to for a re-enforcement, but I did it anyway. The landing gear strut covers will impact the leading edge of the wing in a mishap, no matter what you do since they overlap. I can't beleive that more people haven't jumped on this one.It is a super well done offering. After the attention it has received in MA, I'll bet there will be more activity. A lot of Bipe Lovers are missing out on a really nice ship!
