    Differential Tilt rotor build with EDF (it will crash fast)

    Going to post my build plans, and some of the revisions soon, but basically I got a crappy off the shelf tilt rotor frame and was originally going to just make it usable, but with my new 3D printer and some wish to go fast I'm doing a tilt rotor with differential tilt and an EDF strapped to the...

    3D Printed designs?

    Well I finally joined the ranks of many hobbyist and got myself a 3D printer. I always thought I'd end up with a CNC first or build my own 3D printer however life changed and a 3D printer was my only option. That asside lets get to the important part: What successful 3D printed racers have...

    DRL sim for Linux

    Quick question for any Linux enthusiast out there. Will DRL run on Linux even if it needs to be in wine, and will a Taranis be usable as a controller in Linux. If DRL won't run then can I use the Taranis with Linux on free rider?

    Shuriken 180 Review

    Here is a review I wrote recently on the RTF Shuriken 180 from Holybro for Oscar's blog, I'll just link to the full review from here out of respect to Oscar. The Shuriken 180 is a medium priced racing/freestyle ARF (almost ready to fly) quadcopter, that would be great for indoor/outdoor...

    Battery Connector placement?

    Totaled a frame and I'm rebuilding while addressing my previous problems (screws too close to corners, unnecessary slots that weakened the frame, and some added holes for mounting) one problem I have run into is figuring out where to place my female battery connector. Any ideas? Looking for...

    New to electronics?

    Here is a couple of videos on electrical theory. A really simple explanation on capacitance, inductance, and impedance. This kinda explains why VTx will burn up without an antenna too. A touch up on the basics And if you don't have a lot of time here: If you want to learn more...

    new toy, need experiment suggestions (sensitive chemistry scale)

    So I just got a new toy for a great price, and need to learn how to operate it (I have an operators manual, but have not really tried to go through it yet). I need experiment ideas you guys might like to see. The toy is a Mettler H10 Analytical Balance, and apparently is for accurate...

    Some OT Plane stuff and Meta discussion

    I see no problem posting this type of stuff under general as it is somewhat relevant, and I'm sure some people on here dabble in R/C planes (well at least I've started to hahaha). Perhaps an Off-Topic section with other RC stuff like Planes and helis would be nice if there are enough people...

    PIDs and stabilization

    I wrote this answer in response to this question("Why are quadcopters so stable?"), and decided I might as well post it here also. Multirotors unlike helicopters or planes are inherently unstable like a rock. If you were to power each motor up to the exact same speed it is unlikely you would...
