Hey Jezze!

Your 2W-20 sounds rather high-pitched! I have the same motor running in a Reverb (Mini Hawk) and it definitely does not sound that high running on 3S. The 2W-20 is only rated for 3S and not 4S so I'm guessing you're running a smaller prop than a 4.75 x 4.75.

May I ask what your setup is???

I see you're in Michigan. I was born in Windsor, Ontario, Canada (right across the river from Detroit).

Cheers!

I'm currently using a 4.7x4.7, yes I'm using 4s I've been running this motor on 4s for over a yr. Before it was in a 4s EDF also. I'm considering trying a gm 4.75x4.75.

As you can see I give it a good amount of cool down before I land.

that 2w-20 will get to hot on 4s,,, will it hold? maybee, but not all the way.. I have been running 2w-20 on 4s few times with 4.7x4.7 props,,, to much for the motor,,, if you have really good cooling meaning full airstream threw motor( hole in spinner),, maybee it can take it..

My escape pylon with same setup did go 285km/h , so I guess you see same numbers on your SR 4..

I have same setup now on my HET comet, few burstes only, but the motor is to hot to touch when landed, hehe... I can allready guess it is going bad...

Sebbe,
I have all the cooling holes cut out as you no with the equipment in the fuse there's not a ton of cooling. It does get warm but here in Michigan it's a cold 50*F so this is helping me out. If my Sr v4 is doing 180mph I'm cool with it.

Thanks for the heads up..

It seams fine to me Jezze, the GM folder is nice to save props from being broken!

The Nue or Mega should have it rock on 4S i did 5x5 on 4S, 4.7x4.7 on 5S and a 4.1x.4.1. on 6S (with the Mega)

Victor, thanks

Which mega are you using? I'm definitely a Mega man. I got a buddy selling a 16/25/1.5 which I'm really considering getting. I want to get into the 200mph club..

Mega madness

The Mega 16/25/2 F5D green but not sure if it will break 200mph but try a 5S with a 5x5 APC prop if you can get it. it can still be ordered from mega directly. The 16/25/1.5 sounds nice too, I don't know the specs of it. What's the KV?

I fly my SR on 4S with the even hotter 2W18. I do use a 4.1x4.1 apc prop. The whole 2.3 min flight is full throttle on a 2700 65C TP pack.

Can't believe you are stuffing the 2700 mah battery in there . How do you do it

It all fits nicely, the downside is I have to remove both the wing and nosecone to acces the battery cables.
