Catalyst Macine Works Merica frame caught my eye. I had to have it. I had to redo the original build as the Agard Aio was being difficult come time to add the RX. I installed a Revolt and Bolt and could not get RF1 on the FC so in went Betaflight 3.2 .i did the Sbus workaround and was able to finish the build. Care must be taken when mounting the 4 in 1 tp ensure the battery strap has enough space. Otherwise i love the looks of the Merica. I will be building a 6 inch too
