well I actually have a 36 (trex clone) so I use those. but you could probably still get them, clip them/shorten them to the right legnth (make sure they're a couple mm longer than your stock ones) and them balance them. once thats done you should see that the hole is a bit big and loose. this is on purpose so when they hit, since they don't end and break as easly they can move a bit and not break your heli. I think the blade slots for the blades are the same size as all micro- med micro heli's so they should work. i'm not positive,but if you can't get the head to tighten on right then it's time for some creative enginering
PS: if you want to try look at grand rc for the blades. you can get a pair for only 10 bucks and shipping for me was only 4.00 for 2 pair blades plus a set of tail rotor ones. shipping time was only 3 days too (if you order before 7 it's would only be 2 days) as their stock is located in the US.
