Goblin 570 › Building a 570 I need some advice

I'm getting my first brand new in box kit(Gray color scheme) so it will be my first ever build. I'm planning on transferring the majority of components from my Goblin 500 into this airframe. One of my biggest questions is if I move my KDE 500xf 1350 Kv motor to the new air frame what motor pulley should I use?

I have already purchased full size BK servos for this kit, I will be using my Castle 130 Amp ESC, and futaba tail servo from the 500.

Any tricks and tips would be appreciated.

I'm in the middle of this build so I just did the math not too long ago. First off the motor you were using on the 500 is slightly undersized for the 570. A motor of 1050-1200 is recommended.

However. According to MrMels Calculator to run a headspeed of 2400 rpms with a 6s setup you would need a 18t motor pulley and a 21t tail pulley for headspeeds of 2400rpms or lower

Tricks and Tips

Use Loctite 243 and 648 as specified
Grease Thrust Bearings
Tighten Pitch Arms Before Tightening Spindle
Page 12 make sure to use 15mm screw on radius arms and 18mm on washout arms. They can easily be mistaken.
Linkage Rods are turnbuckles (Install one ball link Clockwise and one Counter Clockwise) I bottom out the ball links and then have someone hold them while turning the rod. This way the ball links are even. Yes OCD. lol
If I think of anything else I'll update the post.

Enjoy the build.

I'm not trying to argue. The new manual I got with me 570 I'm building now.
Electric Motor: 6S–1000/1400 Kv
Your motor will be OK for scale to sport flying. Lots of bog for 3D.

Doing the math for your motor and not using a calculate.
18T = I get. 2619.75
17T = I get. 2473.38

(22.2 volts x ? kv) / (206main/ ? pinion)= HS

Remember you will need some over head if your running gov. (I'm sure you knew that. )

I talked with Bert about my build at IRCHA this year. Bert don't like calculators they all very a bit. Take the time to do the math.

Think you will be ok but you will want to upgrade after a short time. Why not just upgrade at the build and just build and tune once.

If you want to stay 6S as I did. (share packs with my 550X) I personally see/spotted for Justin Cook throwing a 570 around like a rag doll on 6S with a new Quantum 4125-1100Kv.

Sold me on the new Quantum. That's what I'm putting in mine.

But this is all just my thoughts.
Happy building and flying.

I got my kit... I haven't opened it yet... I think I'm going to just go for the 600xf g3 motor. Get the right tool for the job.

Forgot to mention. Every esc has a sweet spot. The g/r that is used on a castle may be different on a Jive or even the new Jive Pro. The calculator takes this into account. The footprint of the Jive Pro is the same as the Kosmik. The difference may be 1 tooth on the pinion but will alleviate strain on the power system.

Good choice on getting the right motor for the job.
