                  Racer X Mutant 4"

Since im addicted to building quads , I figured i should build my first 4". Wasnt trying to build the lightest nor the heaviest of quads, just something that flew well, and was fast. I think I achieved that.

****Still tuning, might try 1606 4000kv motors.

I did try emax 1606 4000kv motors, and did not notice a performance increase, just less efficient. Put the Brother Hobby 1507 4100kv motors back on. Took a lot of tuning to get to fly the way i like, but must say this is my fastest quad i have. Its an absolute rocket ship, and fun to fly.

Hi there ! I have used exactly the same FC - Mamba mini MK3 , connected my crossfire nano wiring exactly the same as your photo. I have enabled Serial Rx on UART1 in Betaflight but I am getting no stick inputs at all. The Crossfire is succesfully bound - did you have this issue ? Can you think of anything I might be doing wrong ??

Have you made sure your crossfire module & receiver are on same firmware? I use a Nirvana transmitter and i had issues with the latest firmware of crossfire, and had to downgrade to few versions below. When i get a chance ill check my betaflight config, and make sure i didnt have to do anything unusual to get this to work.

Yes - when I bound the crossfire nano to my Tango 2 , it automatically updated the receiver and bound successfully - so i assume they are on same firmware.

Did you ever get your receiver going? Sorry for slow response, haven't even had time to even fly lately.

what is the weight including battery?

Boeseefus   Feb 28, 2020 

Ill have to check. I think without battery it was around 150g. Ill check for you when i get a chance

Would love to know this as well, looking for a beast under 250g to play with

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
