Compass eXo electronics setup discussion

[simplechamp]

Hooray, the eXo is here! This is a thread to talk about electronics setups. What works, what doesnt, ask questions and give suggestions.

I'll start with my setup (pulling out of 480XX):

Hobbywing Platinum 100A V3
Stock Rage motor or Pyro 600
MKS HV9767 cyclics, Xpert 3302T tail
Spirit Pro FBL

My question is about motors. Does anyone know if Pyro 600 was tested? I know some pictures show a Pyro mounted, but not sure if it was 600 or 650? Think it will do the job?

I ordered the Rage motor combo kit, just wondering ahead of time if the 600 is even feasible.

[Chris Nifty]

According to at least one of the vids on YT, a Pyro 600-09 was used. The weight savings sure would be nice. Even the 650 Pyro is lighter than the Rage, and the kv is even spot on.
I'll be trying the Rage first though.

I haven't tried my self but im sure the pyro 600 would work just fine especially if your looking for a light efficient setup

Im building one with rage motor, hobbywing 120, kst servos, spirit fbl, frsky taranis with vario sensor that will be used to setup a hard deck with the spirit rescue. If it gets within 20ft of the ground it will level itself and climb back to a higher altitude

Just got my eXo home and tore into it. It looks like my Pyro 600 doesn't have a long enough shaft to utilize the counterbearing. But for this size heli and how I fly I think it would be OK without. I'm tempted to run it with my 3300mah packs and see how it does as a lighter setup.

On the other hand the Rage motor looks very nice and solid. Definitely makes the Pyro 600 look a bit small. But I feel like if I'm going to run that I will need to get some 3700-4000mah packs to really unleash it and still get decent flight times. Decisions decisions....

Is it possible to get the weight of both motors? Would be nice to know how big a difference in weight between motors exists. Hopefully Scott can also post the weight of the Scorpion 4025-1100KV before he mounts it on the eXo.

I am still deciding whether to go with a lightweight setup (with a lighter motor and plastic bodied servos like the MKS 9660As) or with a heavier, more powerful setup with either the Rage or Scorpion 4025-1100 and the metal bodied MKS servos.

The Pyro 600 is 220 grams and according to the specs the Rage is 365 grams - pretty much the same as the Xnova 4020.

I do know that a scorpion 4025-1100kv is insane Because I use to on my 6s 6hvu spinning 600mm blades and its still has power so you could run max pitch (probably 14+ degrees) spinning 520mm blades and still not bog it down.

I dont want people to think that the scorpion 4025 is necessary in the exo but if you want an insane amount of power go for it

I saw Henrik flying a Pyro at IRCHA in the EXO. He had a magnet come loose during flight so I have no other information.

That rage is heavier than my 6HVU motor! That machine is easy enough to bog if I try, but still got plenty of performance with good collective management.

Wouldn't a Scorpion 4015 or 4020 be more appropriate? Trouble is both seem to have 5mm shafts, while the Exo wants 6mm.

The 4025-1100KV is probably one of the strongest motors from Scorpion pound for pound. In addition to raw power it also has lots of torque. On my 550U it is unboggable from 1400 rpm (3S lipos) all the way to 2500 rpm which is insane.

After you build your eXo maybe you can swap the Rage for the Scorpion (on your 6HVU)... A video of the eXo on Rage vs eXo on Scorpion would also be nice to see.

Here are the weights I got: Pyro 600-11 at 231g, Rage at 313g. Add a few grams for the Rage as it doesn't have bullets or heatshrink yet and we are looking at about 90g difference. Interesting that the Rage weighed 313g for me, but specs quoted at 365g, quite a big difference. After seeing them side by side the size difference doesn't make the Pyro 600 look quite as small. I think I'm going to start with the Pyro and 3300mah packs and see how it goes.

Anybody know this guy? What flybarless unit he's using?

Compass eXo 500 - low rpm test - 1600 - 1450 - 1300rpm (4 min 18 sec)

Excellent post Simplechamp. What you did was what I was hoping for... Post the weight of the motors atop a weighing scale. Oftentimes weight posted in the tech specs do not exactly correspond to the actual weight of the motor. It looks like the Rage is lighter than what is posted in the specs. Is there a longer shaft available for the Pyro?

That might be either Keven or Sebastian.

Yea, it's Keven; anybody know what flybarless system he uses?

That's Keven Shauz... He posts here from time to time. Hopefully he will see your question and answer it himself.

Great. I would love to know his setup.

You can also PM him to get more info on his setup. Typically the German Compass pilots use Spartan Vortex FBL controllers on their helis.

[dominator]

He is using a spartan vortex

From what I can find, no there isn't. Guess it comes down to how important the counterbearing is? Of course I'd always prefer using it if the model offers it, but I think with a lighter motor and battery, and my milder flying style it should be OK. Only one way to find out!
