Hi Mike, and again thanks for the answer John..

To be honest I don't know about getting them apart.. I have not had to at this stage..

I may have a different mind set to most though.. I have been flying RC planes for over 30 year and over 10,000 flights in that time.. I onlycrashed once due to pilot error and that was the first flight at the age of 15..

I'm not saying I have never crashed since, I have, but they have been due to mechanical failure, radio interference or structural failure.

Same deal with the Helicopters I have been flying themnow for over 6 months.. over 1000 flights on everything from a coaxial to the 450 Pro.. Again, the only 2 crashes I have had was on a Blade 400 due to Servo failure

and a "near crash" on a Blade SR, which also had a faulty servo - I have since replaced the stock servos in the Blade SR with good quality Hitech HS65 MGs and have had over 100 trouble free flights since.

So when I build my 450 clones, I build them as bullet proof as I can.. Good quality servos, good radio (Futaba FASST) and I solder the motor to the ESC etc.. I then Hot Glue Everything so it just can't move and it can't come loose. Ihot glue the servo leads coming out of the back of the servo to secure it against vibration.

I even hot glue the servo leads to the side of the frame so there is NOchance of vibration failuress.

All my screws are locktited or secured with liberal amounts of Foam Safe CA..

I guess some people may scoff at my philosophy, and yes, it may be more sensible to build with the ability to "UNDO" things as required.. but my system works for me.. and the Clones and components are so cheap that if I do end up destroying a heli due to pilot error, I'll happily just throw the entire thing, servos, gyro and RX in the trash and build another with all new components..

At the end of the day.. if a heli crashes I would never re use thecomponents anyway. I'd just bin the whole thing and start again.. All new parts = Cheap insurance..

I guess if I have to remove a screw at any stageI will cross that bridge when I come to it... but my mindset is that if I build them properly, and use good quality components they will never crash and I'll have them for years.. Which has been a proven formula with my fixed wing planes.. I have one plane that has been flying reliably for over 24 years.. No crashes..

If I get1000 flights out of each Heli I'll be happy.. and am already 15% of the way there with most of them.. sothe cost efficiency is alreadyless than $1 per flight.

Hope that helps.
