Darth,
What I meant is what is say's in my post. Just because it works doesn't make it safe. By using a product such as mineral spirits which robs objects of moisture, does the same thing to the blades. Now I'm not saying it will lead to failure what I am trying to point out is the obvious we are playing with very dangerous products here, why should you take a chance on possibly oinjuring yourself or others because you wanted to save a minute of time. Lets take an example.... say that the injection molder was turned too high before the plastic became a blade, now it's injected and in your hands and you put a product on there that takes away its elasticity even more than the heat did, now your in your back yard flying and loose control. The helicopter hits the ground and doesn't appear to do any damage but it creates a strees fracture in a plastic part that is already a little brittle. Now you start flying again and the blade where the stress fracture occured breaks off. Now forget all about your helicopter and yourself and stop and think about the neighbor or spectators watching. Granted this is a hypothetical situation but we've all seen the gearboxes that we're breaking over the last few years. We tracked it down to being overheated plastic. And guess what? The MR blades are the same material! Don't for a minute think it's safe to use products other than what's recomended by the manufacturer which nby the way the hair dryer trick is recomended by Lite) they might work faster but who knows what it's doing to the plastic. My little rant here is because of all the phone calls I had over the years with people doing just BAD!!! things to their helicopters or flying them inside their living rooms.... I could go on and on...What I'm really trying to remind everyone is that no matter what your skill level something can always go wrong. It says all over in the Lite Manuals that this is not a toy, now stop and think about it next time you use mineral spirits, etc.
