    Could use better instructions

    The happy model site has just short of zero info the VTX port was not configured to be accessed in betaflight, and I could find scant info about the fc. Luckily I came upon a review of the mobula7 and caught a glimpse of the ports tab. Issue resolved. I used this to build a rekon3, which is not what the FC was made for, so I understand the rx and VTX range are not able to keep up. Had I build a micro whoop, I would likely love it.

    Very lite, vtx is iffy

    This thing is great... Except I've a couple that the vtx is having issues. Less range, so move them to whoops

    Good idea but...

    I can't understand if the motors are soldered why doesn't the camera have a solder point?

    Stupid

    This has got to be the most worst setup for soldering I have ever seen unless you are a professional at soldering do not buy this board I have never seen this stupid of a design I bought the acrobee 75 was suppose to come with frsky reciever it had crossfire bought new reciever it wouldn't work fc goes to shit then I buy this fc and it's a load of crap I'm out so much money when all I wanted was a 1s drone to fly around the house with my son. I can't believe how difficult this has been for what started as a bnf setup

    Great weight and value AIO

    I have two of these in my whoops, great value and low weight. I have not had any issues running LiHV on this FC. Easy to flash BF 4.2.9, tune, and go!
