Are you running a from mount frame for the motor?

The 8x6 seems to provide the best performance with the motor (Scorpion 3026/1600kv) battery combo. My setup is not by any means the hottest setup for the Sundowner 36, but since I have smoked 5 motors 3 ESCs (including a Castle Ice 100 amp), it has proven to be the most reliable.
Don't need much to fry a CC Ice 100 just plug it into a Lipo and out comes the magic smoke

@ Vantagepoint.... That should have read:

"Are you running a Front mounted frame for the motor?" such as one of these standoff mounts...



Looking at that Scorpion 3026/1600kV it looks to be a front mount motor and would need something like it. Just wondering what you're using.

The 3026-1600 is no longer avaliable the new one is HK-3226-1600kv can be front mounted by reversing the shaft
A better motor to use would be the Hyperion ZS-3025-06 and would have a better prop selection i would think that the SD 36 would need a bigger prop than 8" a 10" inch prop would give it more thust
I run that same motor in my DF Hyperion HS-3026-1600Kv with 8x6E apc 4s 265035-70c lipos it pulls 102amps @ 1452watts my best speed so fat is 251kph
Just my opinion
Cheers

Once again thanks for the great info Adrian! I notice that mount was no longer available, but needed it just as reference. The funny thing is it came from your post as well in the Sundower 50 Fast Set-ups thread

Is it tough to reverse the shaft on the Scorpions or Hyperions? How much work is involved? It would seem on my SD 50 Scorpion 4025-440kv, the shaft protrudes out nearly the same on each end so it can be front or back mounted.




I have noticed in some of the higher power Turnigy the motor comes with 2 prop adapters, one for the shaft, and one for the frame, so you can use it either way...



I'll look into those recommendations as I do want to run a hotter than legal set-up for my next E-F1 build.

Hi Viper i have never done it but Steve C has and someone else
I still think that 1600kv motor on the SD36 would limit you to prop size and no more than 4s
I have been looking at the SD36 and my motor would be the Hyperion ZS-3025-06 or the Scorpion equivalent
But i just have too many planes to build and not allot of time in my hands

Yeah, I'm not really looking to build a SD 36 right now, rather just trying to see and learn what others are using for power systems outside of the regulated E-F1 arena, that can be applied to my current planned E-F1 project.


I'm with you, so many projects I would like to start, but so many that need to be finished too

Hi everyone Just received my SD 36 and I'm gonna be starting the build soon.As they recommend epoxing the horizontal stab in place ,I was wondering if anyone was aware of a nice video to show a good way to do it.Cant seem to find one on utube.All the planes ive built so far have always recommended ca for the horizontal stab,so I have never epoxied one in and dont want to screw it up and make a mess.Thanks for any suggestions. Dave

I use 30-minute epoxy rather than the recommended 15-minute epoxy to give myself a little more time to be sure things are properly positioned before the glue sets. I also use 90% isopropyl alcohol to clean up the excess. The higher percentage rated alcohol is a little harder to find, but it sure cleans up the epoxy better. As far as a video, I don't think I've ever seen one.

Hi all,

also building a SD 36 at the moment.
Unfortunately my elevator does not provide much throw up and down maybe 10mm each direction. Is this enough?

How much power do I need to fly it? My motor let's me use 3S or 4S. My prefered prop would be an APC 10x10.

First pic is 3S second pic is 4S.

I usually look at the watts/pound as a pretty good indication of performance for my electric planes. With your 4-cell setup, you are getting about 150 watts/pound which is normal sport plane performance power. Your airspeed will be about 70 MPH which should be fine for sport flying and aerobatics.

You will not need much throw on the elevator. I had mine set up on a 3 position switch and flew the plane on low rates (approximately 10mm). Unfortunately after more than a 100 flights on my SD 36, it was totalled today as a result of radio lockout. It was definitely a fun plane to fly.

Power 46

I have just finished a new set up for me, I started out when the sundowner 36 was released with a eflite power 46 with a 60amp esc, and a 5s battery and a 12x12 prop. It flew great and I had no problems. I have re-worked the set up by up-grading to a eflite 80amp esc and a 6s 3300 gen aces battery. I should hit my mark of 135+. I will let yall know.
