ORIGINAL: 46u
OK I am getting there and just had the best flight yet. Contrary to what the poor instructions say in order to get the 4 in 1 to take the change it seems I have to disconnect the battery make the change then plug the battery in to get the changes to take affect. I just hope I have enough blades to make it throw the weekend.
Take it easy with your blades & order a couple of sets of these blades. Sure they're cheap & the shipping from Hong Kong is free, but you have to really crash HARD to damage them:

Also, the Green LiPO is a superb value & the metal upgrades' price can't be beat.
