Ok.. can anyone posts reasons... (sorry I should have been clearer in my thread starter...)
Ease of use?
Reliability?
Lucky Speed with SP noid compared to Blackheart???
Stuff like that?
Between those two it should be no contest. The blackheart is hardly even an upgrade board.
Id like to make it clear that my opinion is biased but to the best of my knowledge factual.
Ease of use:
Display: The stage 4 has a Multi colour LED which shows red for stop, green for go, yellow for error (blue for eyes disabled).
Much easier to remember and easier to tell at a glance than varying frequencies of blinks.
Interface: The interface is in real numbers, so you want 16ms dwell, set the dwell to 16. You want 25bps, set the MROF to 25. No need for an online settings calculator with Spitfire.
Also the interface has preset firemodes for all tournements. The presets change all necessary parameters which affect the firemode.
Its a no hastle way of making your gun legal in under a minute.
No need to become an expert on millenium firemode rules, just choose the millenium firemode and your away.
Reliability
Short term: The spitfire eye logic slows down the gun once the eyes have failed, the blackheart does not. Spitfire eye logic also picks up if the hopper suddenly stopped force feeding and would briefly adjust to gravity feed settings.
On the blackheart in the event of a hopper or eye problem you have to manually slow down your rate of fire by not pulling the trigger so fast, to prevent further breakages or problems.
Long term: If you keep the stock solenoid then they will be equally reliable in the long term. (ie the noid will fail first).
Speed on assisted modes will be the same. Both boards have the ability to fine tune the ROF closely around 15bps. The only difference is there is no mathematics involved when setting up the spitfire board...
Speed on 'semi' is alot different.
The spitfire board has 2 million trigger scans per second and shot queuing.
The blackheart board has neither of these, so if you set your mrof to 20bps in semi (for example), any trigger pull within 0.05 seconds of the previous one will be ignored, resulting in a much slower semi.
The spitfire board on the other hand NEVER forgets a valid trigger pull.
Additionally the spitfire board has 3 debounce parameters, which allow you to set your gun fast and legal.
Stuff like that: Membrane pad... the Stage 4 accepts a membrane pad with no soldering required. (adapter needed)
