Hello,
I've been looking at this excellent site since I purchased a used MX400 on ebay about a month ago. It's a hybrid between the 400 and the 450, most of the metal and carbon fiber upgrades minus the 120 degree CCPM. The purchase included some new spare parts and some wreckage, from a total of three airframes including the 120 degree upgrade. I've spent the last few weeks going over the model rigging, setup and replacing parts as required. It's currently in the 90 degree 400/400pro swash plate configuration (as received), I can handle the mechanical "fix what’s there" but the radio setup for the 450 120 degree CCPM looks intimidating. What I mean is it looks like the previous owner was having a tough time with the 120 and switched back. I gather from reading on this site that it is a more advanced configuration. Don't laugh too hard, this is my second helicopter (ever), my other bird is my little Blade CX. OK, I got the MX400 re-rigged, double checked, stock blades balanced and tracked and then I went out in the backyard and lifted off into a nice four foot hover for a few seconds and then went into the damn death spiral (like a boat in a whirlpool). Right skid broken along with one of the solid plastic blade grip (dog bone) links. Tower order on the way. I added the Castle 35A speed control to make me feel better. My confession to make is my lack of simulator time. I bought the FS1 but the sim for the Blade CX is impossibly harder than the real thing and the collective pitch model is ridiculous. I’m looking for help. A friend with the Real Flight says I need to delete the simulator and reload it with a custom-limited number of models selected? Any help would be appreciated. I'll post photos when I'm repaired and before the next flight. Thanks.
