The reason I wanted to do it with a Rayven shell is because it would be able to have a quad motor setup as the rs would not.
And why not? You are going to take a Rayven and do fabrication to mount a pusher box and cycle control hardware which flat has nowhere to go, but you consider a RS unable to accomodate an afterburner cage?
I see you also used part of a
Rayven in your build am I not right?
A grip frame, but all the problems got cut off and went into the scrap bin. Rayvens are known for alignment issues and general poor fit, And bad ergonomic juju with that thumbhole+battery box deal. Seeing as you want to build a burner, you obviously want performance, so I wouldn't risk the dreadful feeling of getting the build almost finished and finding you have 30 inexplicably missing FPS, which I have seen from Rayvens on multiple occasions because of some bad interaction between the magwell, cage and inner barrel. The RS receiver has WAY better cage mounts and all that. Much less trouble.
I want to reach about 720 ish rpm. Thing is, I want this to be like a REALLY overpowered primary. If not 720 rpm, I would say, 600. I want to keep the stock pusher and just run 2 or 3 trustfires in it. I have an extra blade which I could use for the pusher but then my trustfires just won't supply the current.
There isn't any reason for the trustfires or any other dedicated battery for the pusher. You really should run it on a/the main battery.
A RS motor will never be able to stop at 600, let alone 720. You would have to run no cycle control and then you have an unpredictable, uncontrollable, jammy rig. Plus you would need carbons to run 3S+ on that motor. Definitely run the 180 if you want 600-720.
I have 2 more 16 amp microswitches that i could use for a dual throw and then have the afterburner 2 blades run on my 40-50c 2200mah 3s pack and the startup blades run on a 2s 1800mah pack. The pusher could probably use a diode drop and a 3s from the front flywheels.
Now we're getting ideas. This is a good plan, actually that was one of my concerns, not enough speed on stage 2 to make a major difference in velocity at the muzzle. The 3S would solve that and 2 switches would solve that problem too.
The pusher would go good on the 2S, eliminating the diode drop requirement or reducing it to one diode for 600RPM. You need only use the 3S for the pusher if you want it faster than my vulture mag dump video shows, and again, then you are getting to the point of instability.
