After one year of FPV training and long nights diving into forums, I'm finally getting ready to start buying parts and slowly assemble my first professional multirotor. Since I will be putting a considerable amount of money on a pro level machine, I'm considering building a Cinestar8 heavy lifter that could carry up to a RED, giving me a very flexible work horse for all kinds of jobs. But since I'm quite new to Cinestar builds, I still have many important questions like: Does the Cinestar 8 can be mounted in "+" and also "x" arms configuration without any mod? Since I've got used to small quads and hexas I do prefer X configuration and I also noticed in many Cinestar8 raw videos the front boom (+ build) frequently showing down on camera frame. Is that something I should worry? To carry the RED would I need to make permanent mods to the Cinestar 3axis gimbal or the RED configuration can be quickly changed back to normal for carrying other smaller cameras like the EOS 5D or CX760 ? Regarding motors choice, recently many pancake models made specific for multirotors have showed up in the market. Some shops now have their own branded versions for multirotors. I know most Cinestar8 HL users have been using AXI or more recently 3515 T-Motors (usually rebranded) with good results. The AXIs seems out of my budget and I was wondering if anyone using the new pancakes can say if they perform any better than the 3515 motors. I imagine they can offer lower amps and better efficiency, probably resulting in less expensive distribution boards and longer flight times without sacrificing the required power for a serious heavy lifter. And what would be the maximum propellers size to fit in the standard frame? Actually I like better smaller props and faster motors for stability, but just in case I decide to go with pancake motors that require 15" or even 16" props for heavy load, would I need longer boom arms? If so, can I get a frame kit that already comes with them or that would have to be bought as extra? Last but not the least, In order to make this bird ready asap, I was considering using a cheaper Hoverfly gimbal control board until I can afford the 3 axis Radian system. Is anyone using it with good enough results on a Cinestar 3axis gimbal? And is the Radian really worth almost 3x the price of other controlers? Thanks everyone!
