As 6s is the new 4s, Armattan 3 inch Gecko capable of running 6s with trottle curve :-) Just finished the build and will need to test soon.

Hey Man, Nice looking build! How did you get a micro eagle to fit in the gecko? I'm guessing you are using a different lens than the stock lens it comes with? I got a micro eagle, with the intention of using it in my gecko, but the lens is too wide to fit between the titanium cage. What lens are you using?

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

how did you mount the fc esc stack that has m2 holes to the m3 screws on the frame?

doe sthe stack move around at all?

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

Hey Diems, How's she flying? Tune-able? I'm in the process of building one and considering trying BrotherHobby Avenger 1507 2800Kv on 6s.

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 :]

What's the weight and what batteries you are using?

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

6S on a 3 Inch?? Holy hell this thing must hit the moon on punchouts lol.

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
