Just used the normal micro Eagle in this build. If your lens diameter is wider than the mounting holes on the sides, somethings not right?

I can't have tried hard enough, it does actually fit in perfectly, i was just trying to slot it in from the wrong angle> Very happy it fits in. thanks

Good to hear, happy building ! :-)

Hi, just used m2 metal screws.

You use m2 screws in the m3 holes?

Indeed. the head of the screw is larger than the m3 hole in the frame. You could use rings as well.

i see. thatk you!

doe sthe stack move around at all?

No, with 4 screws and plastic vibration grommets it's fine

thanks. great help!

Hi AirFrame, Initial tests are OK. With the default Blheli32 config It had some problems with max throttle but after changing PWM Freq to 48kHz and Demag Comp to high, it worked fine. The thing is same tunable as 4s but need some adjustments in the upper throttle range. Fiddling with TPA did help. I do need to take some time for fine tuning the PID's.

The 6s throttle curve is based on a excel calculation sheet which you can find on youtube (search for 4s motors on 6s). In the excel sheet you can enter the kv you have and the kv you like to have on 6s. It will output the throttle curve. When testing, you can than validate ESC amp load and motor temps to see if you can push it even further. So theoretically, you can surely go with the 2800kv motors and possibly even higher to give you the wanted 4s performance. If you do go with the higher kv on 4s, you need to be sure to monitor the ESC amp load and motor temps more closely but you will have more headroom to play with as long the ESC and motors can take it.

Let me know how it works out :]

Without lipo 171grams and currently testing with 1000mah 6s which are a bit on the heavy side .. Think I'll settle with 850

I'll find out this weekend. Let's hope it returns in one piece :p
