I like the Arreaux due to its versitility and durability. It is a solid little rocket and it can fly on a 29mm H with no propblem should you desire. (A H97J will put it up to above 3700', and has a nice black smoke trail which with this rocket is helpful!.... although If your going to fly it on a H make sure to put a Tracker in it!)
The Fin-Lok system seems to work well, and the fin fillets are cast into the fins, however you may *want to (not need) to perform some touch-up fillet on the fin roots as there may be some very small gaps between the fins and airframe. (See photo below)
The mesh cooling system does actually work, and is replaceable. I haven't even so much as singed a chute (yet). but I use a small nomex blanket in just in case. The inside still looks almost new, despite several flights, and still has only minimal ejection residue / discoloration (See photo)
I personally did NOT put it togethor with CA as per the instructions, but used 30m epoxy instead. Also, I ditched the shock cord that came with the kit and replaced it with kevlar instead, and added a bit of vinyl (or whatever the stuff is made of) gas tubing at the point it exits the Airframe as protection against the edge (Zipper)
You *probably* could fly it on an Estes' 29mm motors but you would need to build a thust ring from tape, (or a small piece of motor tube glued to the end of the Estes motor casing.
DISCLAIMER: I have heard of this being done, but have never actually done it myself so I *don't* actually know if this is legal with respect to rules not allowing the modifcation of motors.) but AT anb CT make lots of 29mm stuff that would work.
Its also a fairly small rocket, packs well, and because of its fins, is pretty car friendly in terms of being bounced about during transport!
Anyway, I like it!
