The original Ultimate has a 7X29mm motor mount.
The Ultimate Mini has a stock 18mm mount.
Made the stock mount interchangeable and scratched a 7 motor MMX mount using a cut off 18mm engine casing and a coupler.
Still nekkid, hasn't maidened yet.
(PS motor mount retention is tape wrap).
Any tips/experience with lighting a micro maxx cluster that big? Offhand I would think it would be quite a challenge. My Diminutive Deuce is hard enough to get both igniters lined up with the rocket straight on the rod...
I seem to recall a tip about using the broken off tips of toothpicks to hold igniters in place.
Don't know if that came from the instructions or elsewhere.
Otherwise, I have a small roll of thin Nichrome wire I can use to make extra long igniters. Just have to mash the tip and lower the resistance.
Or..........
Plan C: mini flashpan
Plan D: tiny, tiny little fuses.
Thats a lot of action for micro.........
Flash pan is cool loved it when I was a kid but never heard of anyone else using it. Lots of my rockets when I was a kid were burnt from this.
