Anytime i look up the hilliard flame it's always talking about the l206 but if i just change the engagement speeds then i should be able to put it on a stock predator right?
No problems at all -- but you WILL need to change the springs to get the engagement considerably lower.
With white/black alternating, you'll be around 3400-3600 rpm for the L206.
Depending on how "stock" your Predator is, I would think that engagement will be nearly 800-1000 rpm lower than that.
