I wanted a longrange cruiser and I was not very successfull with my Spectre build. So I decided to go even larger and bought 7" Freestyle frame from AmaxInno, new KISS 4in1 25A esc and KISS v2 FC hoping it will be peace of cake. It turn out to be bit challenging build because the body of the frame is really small and I wanted Micro MinimODS because of RSSI. That required adding 5v BEC. Matek VTX-HV also did not fit in so I bouth TBS Unify instead.
I managed to fit all in and hover test was fine but the real first flight was a disappointment. Way too much vibration. I had to play with PIDs a lot and it took me a week. Finally I am getting somewhere and the tune is getting closer and closer to desired state.
Other than that this quad is great. I really like how it flies and how effective 7" is. It seems like you can fly forever.

I was not very successfull with tunning and I almost gave up on this frame but then AmaxInno released v2 which has 6mm arms that made the frame stiffer and jello went away. It is ofcourse havier but it is worth it.


I moved the KISS parts in between my frames and they ended in my Rotorama Spectre. So I have grabbed some older spares and put them into this AmaxInno v1 freestyle frame with thin 4mm arms. It will be nice test platform for upcomming Betaflight 4.0.

hi, very nice setup. i would like to use the 5" amaxinno fresstyle frame with kissv2 and wolf pdb. do you know if it's possible with this frame? thank's you

I am wondering about WolfPDB aswell. I am not totaly sure about it. You would probably need to put the nuts that are securing the arm from the bottom and then it could work.

Hi! Nice build! I want to make something similar to this... Kiss fc v2 and 4in1 kiss esc 25A with chameleon ti and steele motor... But I have a question, fc and 4in1 esc are connected throught only one cable? this one
And your xt60 cable for lipo is connected to the esc or directly in the fc?

thanks in advance :)

miromir237   Aug 28, 2018 

FC and 4in1 esc are connected throught included cable. I am powering the FC from the pads on 4in1 near the cable connector but you can use pads for xt60 as well. The KISS v2 suppors 2-6S.
My xt60 goes to 4in1 esc.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
