TWIG - Racer X - with RPM filtering

By JimmyProton on Nov 05, 2019

17 920 10

Racer X Speed Racer TWIG build. Running BF4.1 with RPM Filtering. Flashed J-esc firmware. BetaFPV AIO supports J-esc...
Also, to avoid confusion if you are looking at my wiring as a reference, I am running F-Port on the R-XSR.

Fly's great. Very efficient and FAST.

Cheers!

update: Switched to HQ 3x2.5x3 from the 3x3x3 props. Slightly less current draw, lighter. Improved performance and better prop wash handling.

Nice build. The third picture helped me wiring one of R-XSR that's acting up, I couldn't wiring it on the SBUS pad, but uninverted + TX2 worked (sorta, still no telemetry)

Gorgeous! Did Jared inspire you?

JimmyProton Jan 07, 2020

Yes he did!

Can i angle limit this drone?

JimmyProton Nov 27, 2019

If you like. You can angle limit ANY quad running betaflight (Assuming you have the accelerometer enabled). But whats the fun it that!?!

LucaFur23 Dec 03, 2019

I have experience to fly. but it's been awhile since i've ever flown a FPV drone, so i would need to angle limit for a little before i rip the boom off my drone like i did the last time.

hows the performance of these motors? i saw the test numbers tested at 98 C on just 2S. Do they not get hot on 3S?

JimmyProton Nov 18, 2019

So far so good on 3S. I've flown it pretty hard outside and have not noticed the motors coming in more than luke warm.

LUV YOU JIMMY!

And yea, before anyone comments, I intentionally put only one screw in each prop initially to create an imbalance in order to test the rpm filtering.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
