ok, the only tools you will need are usualy allen wrenches, it's best to have all the small METRIC sizes at home (1mm up (not sure how low it goes but pretty small, I do think the smallest is 3mm though)) Also it's good to have a case of jewlers screwdrivers avalible. If you remove the frame it uses (I think) the largest size screw head avalible for glasses, Just make sure you have a size small enough to fit in the holes on the frame and the four sizes after that. The Jewlers sets are invaluable for this and if you don't have one I'd suggest going out and buying yourself a case, belive me, they're VERY hand to have when playing with electrical devices, Also all the screws on the heli are MAGNETIC so a few 2x4x5mm N50 Neodymium magnets are WONDERFUL for keeping track of those screws as it's really hard to pull them out otherwise. not a nessity and if you buy extras they're the best refridgerator magnets you'll ever buy. (don't be fooled by their size they can hold twice the weight/thickness that any magnet you have currently, unless you already have neodymium magnets....)

blade higher? is it PHISICLY higher as in the spindle shaft in the rotor head (remove the blade grips to see) above the other, or just the PITCH is higher? if it's just pitch I explain how to adjust above, mainly just by twisting the ball links on the rotor head on more or off more.

PS: please make sure you read through the whole manual, first before adjusting anything, and ENJOY, I hope this helps ease a few frustrations that come bundled in this machine.
PSS: need some magnets? just look here, this a great place to bargan buy magnets, and I think the guy will actually custom make magnets to order, real friendly, just email the number of the magnet you want. http://www.engconcepts.net/List_Of_C...ce_Magnets.asp
remember the higher the N rating the stronger they are, size affects how far they pull/surface area of pull.
