Sweet Green - Toothrip stretch!

Intent was to have a clean, minimalist, and "organized" stretch build. 3" is larger than I have been flying as of late and wanted to do something different. I really like the thin arms that are thick approach as well as the grassroots company/design through T4bee and Armattan Productions. I chose the reinforcement arms to build in some strength and establishing a planned break point when I crash. The canopy is VERY tight fit on the camera, but some smoothing and a lot of warming of the TPU enabled the tight fit. Surprisingly there is enough room for camera and the VTX03 in the canopy.

Have two different props to try... more to come when I can report.

I cannot find the link for the buzzer holder, but I do that the STL file. I apologize for not being able to attribute as I clearly did not design it.

You will need 10mm M2 hardware for the motors. Landing feet, motor pads, the think 4mm frame and the cross arms.

I know that there is one stand off missing, was tuning with BF and it needs to be removed for USB access

Battery pictured is a 850 mah 3s with XT30

I really liked this frame when I first saw it on RC Groups but was extremely dissapointed that on Armattan Productions the carbon is NOT cut with the carbon weave going down the arms (extremely disappointing given the frame cost), so in a hard crash the arms could easily crack. I just broke two frames with a total of ~40 flights using light 8.9gram 1108 motors due to improper carbon orientation on the arms. It's good you have the braces - they'll go a long way to strenghtening it. I just saw the new RCX X120 FPV frame which is almost a 100% copy of this frame. I don't like supporting Chinese clones, but this frame has two major improvements: it has the carbon orientated correctly (yeah!) and second, it improves the motor screw hole area (an area likely to crack). Best of all, it includes the 3mm frame, TPU canopy and hardware all for $16. I'll post my build with it when I receive it in a month.

works well... tight fit, warm it up a fair bit

Oh man, this thing looks MEAN. I didn't realize RK had put out new 3" props; what do you think of them?

Wait, I just realized those are iFlight props in your photos. How are they?

I do not have anything other than "hover" experience in the basement just yet. Finished up the build... work trip... then we got 20+ inches of snow. Because of that, it might be a bit until I can fly for real. First take as soon as possible. I have had the RK 3076 and it made a set of F20 motors kinda angry and warm

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
