I started, after the usual Small and Sim, with Trex 450 belt (3 HK and Align Trex 450 Sport), and then went to an HK 500 then a Trex 500 Pro. I do like the belt for easy repair, but the shaft is slightly better than belt. I did choose the 450 because batteries were same as my planes. I then went to a 500 with 6S batteries, and just bought a Trex 600E because I can use 2 of my 6S in it. In the end, it is about battery compatibility for me.
I added a Bell 500 fuselage to one of my 450 along with a 5 blade rotor. I am about to put a Flymentor on it because it doesn't have a flub at obviously.
Once you start, it seems like it never ends

So would you recommend Trex 450 as my starting point...and then slowly move on to the 500 size?
