![]() ![]() Most racing/freestyle quads I've seen on YouTube are using somewhere between 20kv motors. Motors are spec'd based on the diameter and height so 1806 is 18 mm diameter and 06mm height, they are also labelled with a "kv" value for the rpm per volt applied, so a 2300kv motor with 4S (14.4 nominal voltage) then you get 14.4*2300 = 33,120 rpm. Regarding ESCs the 32-bit BL-Heli based ones are I think relatively fresh and from my experience so far have worked well, mostly you need ESCs that will deal with the amperage the motors will pull at peak for whatever time you expect to be full throttle, I believe 35-40A is "good enough" for most applications/hobbyists. Currently F4 is basically old news and best to have at least an F4 based board since F3 can't support all the features Betaflight offers anymore (basically the software/cpu time for functions has become too much for F3 boards to handle without disabling some things). The links for the motors etc seem to still be active there as well. If you do decide to go the print it yourself route I know that this one works and flies pretty well moving to a bought frame from Amazon or elsewhere is pretty easy as well since it's a pretty standard style for most modern 'racing' or 'freestyle' quads. If you are doing this as a project to build skills for building and fixing the quadcopter then it makes sense but otherwise if you just want to dip your toes into this hobby would suggest doing something like suggested and just get something small/cheap ready to fly (make sure this isn't a quickly passing phase/fad that you'll regret spending hundred of dollars and time on). ![]() I don't mind spending a little $$$ if there is a much better/improved body to start with (in terms of weight, or supporting more payloads/electronics "out-of-the-box", etc). If I need to go larger in order to have something that's a bit more than just 10 minutes cruising around in the backyard, then I better know that sooner, rather than later? The T4 appears to be about the largest body my 3D printer can support. So given all that - should I bother to continue investing in the T4 Quadcopter as a body/frame? Or as a learning platform, is it as good as any (for its price)? I am experienced with the cheaper (<$100) FMV mini-drones, so I get the idea of them jumping into the air on startup, trimming out the rotors, basic idea of the challenges of lift versus current draw, and how that class of quad is just battery limited to 5-10min flight time (afaik). I don't mind a heavier build that is more stable when flying outside, prefer >20 minutes flight time, and has decent range (maybe 1/4 mile in both flight and video stream). I see some nice commercial kits for under $400 (even at Fry's and elsewhere). We're not looking for a super fast racer. My main question is - how efficient or suitable is that T4 design versus what is available today? Obviously the videos prove it can be made to fly, but how "strong" and stable is it really? ![]() Brendan may have moved on from the scene, and the parts list posted is mostly dead links now - that's understandable, it's now a 4+ year old design, parts vendors move on. ![]() We're printing a standard T4 quadcopter from Thingiverse (thingiverse item 261145). My daughter is curious to build a quadcopter robust enough to operate outside, and I do have an engineering background so I think I can help her out. ![]()
