Just thought I share My Arrma Infraction probably a little late on picking one up. But it was on sale over the holiday and figured I grab one since it was cheap. Anyhow I added a new Brushless Motor and ESC by Castle Creations 7700KV motor Copperhead Series 14 I believe. Link it with a 3S Battery and DX3 Transmitter with AVC an paired with a SR315 Receiver.

Nice and Clean conversion. 👍
 
Nice build,nice to see something other than a firma150a 6s system in one...nice array of parts...7700kv is up there...may overheat on 3s,gear appropriately an I think it'll be okay...with hot racing spool I've tried many motors 2000-3900kv has worked best for me for 3,4s speedrunning with vendetta....

I was actually looking for something in a range of 3900KV but then I ended up stumbling onto this one on Horizon Hobbies website. All I know is this thing is nasty fast lol

I love nasty fast,my vendetta is currently the world's fastest 3s vendetta,used tp4050cm 3800kv. It's also world's fastest 4s detta,used tp4060cm-3480kv on 4s...both great motors that are also stupid fast...I imagine that 7700kv just keeps building rpms...ever ran it on 4s??

That’s my next challenge 4S 14.8V battery I’ll get one and see how much more faster this will be.

Cnhl 70c are about the best bang for buck.do you parking lot rip it or more speed???

4s would probly blow it up...only pay attention to volts an rpms on calculator....ya need to find out max rpm for that motor..4s would put it almost to 100,000rpms🤣😂😆it's probly a 80,000 max rpm motor..so I'd watch temps close an often on 4s

Here's my detta on 4s with 3800kv,47,000rpms..I believe the highest rpm pass I've ever made...

Here is just a short Video of my Infraction just testing the speed, the torque is crazy.

 
I'm building mine just now. Also 150A esc coupled to a 4274 3600kv brushless. I fitted the 20T pinion / 50T spur combo. Want to run it on 3S. Now, after putting it all back together the drive line is much heavier... Still have to test it though...
