I think you are absolutley right there with all the rules and regs. We have been doing this slow combat using .15 size engines for over 8 years now if my memory serves me well and to date we have not had any whining, complaining, etc etc about our slow combat rules. Everyone comes out and we just have fun. Only major rule is safety of course.
Interesting concept using old trainers for slow combat.....definately slow for sure...... I think that there is merit in that concept.
For those who want to get into AMA combat, well there are many venues for that as well, but for the rest of us....slow combat with minimal rules is the way to go.
I would be interested to see how you guys make out with the slowcombat using trainers.
