Not to argue the point of saftey by not using mineral spirits. Mineral spirits is petroleum based product and so is most plastics. To sit there for five minutes with a hair dryer is kinda long to remove a couple of stickers. All I do is peel the stickers off the best I can and then get a rag and put a little mineral spirits on it and wipe off the gummy stuff that was left behind. Less than a minute to do both blades. A hair dryer and heat wouldnt that have a greater chance in warping the blades ? Even in a crash Ive never broke a blade where I removed the sticker using min spirits. As far as saftey is concerned, theres alot of things involving a helicopter that isnt safe. Especially with the nitro helis. what about fuel, spills, flooded carbs and the danger that presents when hooking up power to your glo plug. Spark could cause a fire couldnt it ? When I got my heli it was dangerous trying to start the thing even looking at the suggested methods in the book. Also trying to start the heli while holding the plug igniter on and holding the starter at the same time. i still havent found a glo starter clip that will stay on by itself. Safty issue concerning z links, those things seem to be notorious for comming off, even in a boom strike. There is alot more pressing saftey issues to rant over than about someone using a little mineral spirits to remove sticker adhesive. For as long as Ive been hearing about the difficulties of getting the stickers off, I would have thought that LiteMachines would have remedied this by at least going to an adhesive that was not as sticky. To put this on the level as flying the heli in the house is like comparing apples to oranges. Flying the Heli in the house and or around people is in a class of stupidity by itself. Especially around kids who dont have the perception that those spinning blades will hurt and cut if it hits you. i can remember one time flying in a park all by myself and all of a sudden i see this lady bring a herd of daycare kids to the park. Immediately they ran toward where I was because of their attraction to the heli. I litterally had to stuff it into the ground because these kids were running toward me fast and it was all I had left to do to be on the safe side of someone not getting hit. Of course I gave a lecture to the lady who was responsible for letting them run up to me like that. She just really wasnt aware of that danger. Oh Yes, Im glad it was a LiteMachines I put into the ground and not another Heli.
