I recently purchased both a 250 and 450 and I"m not sure of the correct hex driver sizes I'll need for both heli's. I know the 250 uses at least a .9mm. What other sizes will I need for both heli's?

Recommendataions for the best price and source to buy would also be appreciated. I was going to go with a set of Wihe drivers but now, I'm hesitant since I found a bad review on them. Anybody tried these? Although Thorp drivers are top quality, they seem a little pricey.

Thanks guys!
Dan

Easy way out
I just figured this one out the other day " and I'm known too be a tool pimp" Didn't even remember I had a few set's

Pick your self up one of the cheap kung foo screw driver - "multi point tip set kit's" Little plastic case with at least 20 or better different tips that fit into the 1/4" hex drive of the handle.

My set's have SAE, Metric, JIS, Torx, and Security Torx, beside the Phillips and flat blades in them.

Just the bit alone in your finger tips is usually adequate.

Best part one of the kits I have has a extend able magnet and the handle has a smooth reversible ratchet clutch in it.

The 450 uses mainly the 1.5mm. 2mm for engine mounting bolts and 2.5mm for main blade grip bolts.

I have the align hex driver set, and I like them and would recommend them. I've heard good things about the mavrikk set though.

As for the 250, I don't know. 0.9mm, 1.3mm?...not sure
