So I am off and running, well sort of. It was great until in the large garage I got too much height, lost co-ordination and, yes, the first crash. So am waiting for the replacement blades (and spare set now of course) and outer shaft main gear which has a few ripped teeth. In the meantime the Phoenix sim is doing sterling work.
This gave my my first chance to get to grips with the mechanics of the thing and use it as a starter-for-ten on RCH mechanics. At the same time I had (somewhat naievely it now appears) followed the manufacturer's recommendation and bought a heat sink for the motors, so thought I might as well fit that.
I took the guidelines for dismantling a CX2 from http://www.s5000.net/phpBB2/viewtopic.php?t=17746, which, of course, are excellent.
The CX2 instructions for fitting the heat sink simplistically say remove the right hand motor and then the heat sink will fit. Yes, but the gear wheels at the bottom obsure good access to one of the screw heads retaining the motor, so the gear wheels have to be removed!
Just a couple of points I found for anyone who hasn't done this before.
1) The inner shaft retaining collar has two retaining screws. These are very tight and I found that a jeweller's screwdriver does not give sufficient purchase; there is also the danger that it will slip out burring the cross head screw in the process, so I used a proper Phillips screwdriver which you can make sure is firmly seated and kept there whilst applying considerable turning pressure.
2) After removing the lower rotor head there is the outer shaft retaining collar and a bearing to remove. As might be expected the latter is very tight fitting. So tight that where screw for the retaining collar goes against the shaft it has displaced some metal so that this is proud to the surface and this needs to be carefully removed before the bearing (not forced) will come off.
Getting to fitting the heat sink it transpires that both motors need to be 'free' and some manipulation of wires is necessary and then, with care, it all goes together nicely. Use cotton buds to appy the heat sink paste and use meths on cotton buds to remove any excess paste.
Refixing the left motor (with heat-sink attached) is no problem. The r/h motor is then fitted to the heat-sink but check on re-screwing it that it is fully seated against the base-plate (main-frame) or else the cogs for the grears will not be in their correct positions. Again for anyone new to this make quite sure the motor screw holes are accurately aligned with those in the main frame and that the motor mounting screws are turned the reverse way first until they 'click' so avoiding stripped threads on the soft metal casing of the motors.
Finally, I am tempted when putting things together to add some lubricant to the area between the inner and outer shafts, for example. Does anyone have any comments on this please?

as the blade is such a good beginers heli its good to post every thing you do no matter how big or small. you never know you may have just saved sombody a christmas in the casualty dept with a screw driver through their hand!!!!
