Plastic basher

A black-and-white plastic basher!

This is my first build and the goal was a cheap basher to get some more acro experience on 5" quads before I build something lighter but more fragile. The frame is an HDPE  classic X and weighs in at about 180 grams with the extra cap and frame hardware. Total weight without battery is 416 grams and this little thing feels so snappy compared to my other miniquad (a junky Eachine Racer250 I flashed to Betaflight).

As you can see in the picture of the 4-in-1 esc, lessons were learned when cutting wires. Measure twice, cut once. Unfortunately I didn't have any wire to spare except for the cuttings and it's impossible to find halfway decent wire around here, so a temporary patch was made. I will probably be replacing components due to in-flight lessons learned in the near future anyway. Also anticipating a lesson in antenna vs prop, so the second antenna of the R-XSR is inside the center of the frame, safe from harm.

Modifications were made to allow the battery cables to exit in the rear as the frame is designed for side-exit power connection and I didn't like the fit of the esc rotated that way. The camera mount was a little too deep for the Eagle 2 and blocked about 10% of the left and right edges of the screen so the 3D-printed hood had to be trimmed a bit. The only problem with the frame is that it doesn't have any access to the FC's USB port so it has to be partially disassembled to connect to the computer. Once everything is set up, the LUA script for tuning via Taranis will reduce the need to access the USB so it isn't much of an issue.

Looks like a great build, you have made some GREAT choices. The back to back $30 for the VTX/FC and 4-n-1 is particularly good (but lets not count the rad $10 motors out). I think you are wise to choose the 3-D printed plastic frame, a lot of people listen to youtubers that have tried a LOT of things. The downside to that is you rarely hear the commentary from their early days, and someone might have spent a year or more in a plastic frame with NO REASON to complain, then you hear them freak out about how their new lighter frame feels more nimble. That doesn't mean that the plastic frame was anything less than spectacular, they just preach the new hotness cause' they're excited about it. The thing that a new pilots frame needs to be are: durable and servicable. BTW that black canopy on the top is super slick!

It scales in without battery at 416g but is still drastically more nimble than the Racer250, which scales at 412g as I've got it set up. The 2207 motors and 35amp escs are a huge difference but there's also the change from CC3D with PWM on the Racer250 to an F4 with Dshot600 in this one.

I really enjoy the research/build/tweak process involved with FPV multirotors but I need to get my flying skill up so I don't end up building something amazing to smash into the ground at 100mph.

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..
