I had considered that and ruled it out due to cost, but it seems like getting a "unique" 450 runs about the same cost as a 500/550 size bird.

If I were to go bigger, I think I'd stick with the 500 size though. 500's appear to be able to use 2x2200 3s batteries, which means I don't need new batteries since I already have a bunch of them. Upping to the 550 seems like it costs significantly more in all respects (just my observation though).

Of the 450's that Hirobo looks the most interesting. That servo/linkage layout for the cyclic looks nuts. Plus, I have a soft spot for Hirobo products, as a Hirobo shuttle circa 1985 is what got my addiction started. I flew it for all of 3 seconds before I freaked out, pancaked it, and had a boom strike. But the seed of interest had been planted...

Thanks for the replies guys. I'm all ears for further recommendations.
Atom 500 would work great for you and you can upgrade it to a 550 for only the cost of a boom belt and blades

run it on 6S mind you 6S 2200mAh will drastically limit your flight times think <4min most 500s need more like 2700 to 3200 to get good flight times and not kill packs
i run 3000mAh packs in my 500 and 5min flight times the packs come down ~22.8v and i put pack in ~2200mAh
but this is at a goved head speed of 2600rpm if you when lower like 2400 you could get by with 2600mAh packs at 5min
but 2200mAh your looking at running 2200rpm which is getting on the low end for a 500 to get 5min flight times

really the only helis that share packs well are 6S 500's to 12S 600s and 6S 550's to 12S 700's
any thing else not so much
just add servos, RX, FBL controller and lipos
maybe $1200 all up with Savox/Align servos and AR7200BX + sat and two 3300mAh 6S packs

oh and every one copied the "DFC" rotor head from Compass but left out the part that made it work lol the delrin links to the grips
seems Compass patented that part
