Suggest check out ecalc.ch is great for getting some in theory numbers just takes some time to understand the interface but plug in some close parts and see what it calculates.

If you haven't flown before might want to pick up a tiny hawk or similar small prebuilt as well since they are more durable and can be a lot of fun (just get a lot of batteries). Also simulators like lift off or velocidrone can be good to get feel for how much you need to tweak around with...

Ah dang well the soft mounting should actually help, I wonder if betaflight filters are preconfigured for the frame resonance of CF with soft mounted FC like you have but the aluminium frame is causing some issues? Basically the tpu or soft mounting ideally physically filters out the small fast...

Ah yah that should be all good actually it's a bit confusing because the stm32 chips get used in lots of different flight controllers (f3, f5 or more recently the f7 chips). The main chip on the flight controller board is probably that chip but there is board config that tells betaflight which...

Yah if you arm the quad and it has stabilizing mode on then the motors will sort of drift around in speed on the bench but if use motors tab to control them individually then they should basically ignore the stabilization and pid loop is just sending throttle signals more directly. Same with bl...

Would bench test where run each motor individually either from betaflight or from blheli suite (props off). Basically if everything responding as expected when using sliders in the motors tab of betaflight or bl-helisuite then can know the signal from FC to ESCs is working fine and see if...

Sims are great for getting overall stick motions figured out for like power loop or split s or going through gates at weird angles in real life tricks tend to result in exploded quads if I haven't got them locked down in sim. Real life risk adds a lot of pressure for sure and sims never match...

Also if you are suspect of if some motors or part of a ESC or individual ESC fried out can swap motors, if the problem moves with the motor it's a motor problem, if the problem doesn't move with the motor it's probably an ESC or signal from FC to ESC problem.

I would guess this could cause the ESC to fry, they are pretty sensitive to spikes in systems and if the free wire shorted things between the outputs or otherwise caused some other part of the ESC to short then the ESC is likely fried. One thing might not be aware of if new too is the CF frames...

Simulators like "lift off" or "velocidrone" save lots of time effort and cash in rebuilding but no sim gets close to real world in terms of locations (ms flight sim aside :) )

Yup agree just bring a screw with is your best bet to get a match, but just heads up most of the screws I've seen on quads are m3 (3mm diameter) or occasionally m2 or m2.5 (smaller quads usually use the smaller screws). If in the US Ace Hardware stores usually pretty good about stocking metric...

Discharge charts if for a specific cell can be used as well but each lipo has different discharge rates in reality so ymmv to some degree but in general a discharge chart from trusted third party probably gives pretty good baseline (the "idle or hover draw" due to power to weight of a given...

Depending on the rx/tx being used you might be able to get telemetry data back that includes the current battery voltage usually can make a table for a given battery of voltage to rough percentage based on total flight time and recording the voltage as time passes (it varies depending on...

Encryption really important for like email you want to stay private or sharing credit card info on forms to buy stuff etc. Less important for public domain stuff you're just trying to distribute.

Yup is same issue of no encryption I tried explaining above in some cases like here where not really sharing personal info the only issue might be someone stealing passwords that people might reuse elsewhere but if use a password manager or separate more important accounts with different...

Oh one more thing, if not familiar with soldering small wires onto pads suggest getting "hemostats" for holding wires without burning yourself and always tin both the wire and the pad (cover each with solder first) then cut the soldered part of wire to be a little nub and solder it to the pad to...

https://www.getfpv.com/diatone-mamba-easy-f722-mk1-flight-controller.html ^^ should be good and fits in the price range basically any F7 FC has the same processor at the core of it so is just variations on the other components on the board (IMU mainly) and layout of the pins/pads (some have...

On computer side can use a keylogger for capturing input from keyboards I imagine there is some similar kind of joystick input logger could use on that side too but the problem still exists regarding how do you plan to use the data?

FC doing black box logging can capture the data or if want to go direct from transmitter can use a special function to save the telemetry data including sticks to SD logs (on the transmitter then no FC involved)... How you play them back or use that data is the issue then

You seem to be missing the part that the FC can pass through the signal to a computer to use for Sims?
