FPVCrater Racer
By DoubleJackOnTap on Apr 02, 2020
Update 4/5/20: Hover test and FPV maiden flight went great. I flashed the FC with Betaflight 4.1.5 and turned on RPM filtering. I left the default PIDs and rates for the maiden. I was very impressed with how it flies. Propwash was almost non-existent. This is the best flying kwad on defaults that I have ever tried. Im exited to see what a little tuning can do for it. First flight was on a 850 mah 4S battery, so I wasnt able to push it too hard. The next flight was on a 1500mah and it absolutely rips. Very fast and very responsive.
Weight is 324 grams with lipo strap & without battery.
Weight is 420 grams with 4S 850 mAh Turnigy battery.
Weight is 503 grams with 4S 1500 mAh RDQ battery.
This build was constructed entirely from parts out of the FPVCrate subscription. (except for the receiver). The canopy is very finicky to get lined up with the mounts for the camera, otherwise the build was relatively straight forward. My solder joints on the ESC are terrible, so please ignore those. The ESC that arrived this week from the March box did have some issues. ESC #3 wasnt flashed properly and it caused me fits, until I figured that out. The sun is supposed to show up later today or tomorrow, so I hope to maiden it then. I will post an update after the maiden flight.

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..

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..

Can you tell me where to put the FrSky R-XSR? Diagram has the RX Port (right side) with a GND/5V where in what UARTs go S.Port and SBUS out?
SPort to T1 and SBUS to R3.
Here is a link to the FC. They have two images of wiring diagrams. I tried to upload but cant for some reason.

I have a TBS Unify Pro32 VTX connected with the Smart Audio to the TX3 Uart pad by the VTX connections. I don't think I can connect SBUS to R3 and have two different functions (Smart audio/SBUS) on Uart 3? (Smartaudio on T3 and SBUS on R3)? Or can I? Sorry somewhat confused. Maybe I can have two different functions on the same UART because one uses the Transmit function and one the Receive function?
Ports tab: Uart3 had Serial Rx ON which I assume is the R-XSR because now my Taranis X7 is working in the receiver tab. Also, it appears SmartAudio VTX switching is working (throttle mid/yaw left/pitchup) because I see it on the screen and it works (haven't set VTX table up yet for UnifyPRo32). Yet I don't have "VTX (TBS SmartAudio)" selected on the PERIPHERALS column in the ports tab for any UART? But it still works?

Think I figured it out. MOved the SBUS from T3 to T5 and now both the receiver and VTX work :) Nothing like trial and error!

This thing posts weird I mean R3 to R5 no double tap
Glad you got it working! Are you going to post the build?
Sure what do I have to lose only a little pride but everyone starts somewhere LOL!
