I created this video that explains a simple setup of a gyro on the Dx7

Well look at the video it says it all, but I got this gyro and pulled it apart and found it was identical, also when I mounted it onto my HK450 the gain was also exactly the same as was the travel adjustment.

Gyro Mounting Which Way

Well this is a simple video to explain how a gyro reacts, you have probably seen gyros mounted on the side of a heli and some underneath well it all comes down to which way the gyro reacts. Look at the video and then you will understand what I mean. Then once you work out which way it reacts you mount that reaction angle parrallel to your rotor blades, it doesnt matter if it’s at the front of the heli, the back of the heli top or bottom of the boom mounts that is, but so long as you mount it the correct angle, if it is wrong then the moment you tilt your swashplate you tail will spin into a piro and flip the heli around and you WILL CRASH, so make sure it is correct, and ask ask ask, most gyro have the writing and adjustment pots face the ground / or the sky depending if you mount under or over, but there is no upside down for a gyro just horixontal or vertical, work out which way it reacts and imagine your heli turning in that direction then you want the servo reacting in the opposite direction well your tail really…

Green Loctite HK450 Tail Gear Fix

I was at a field one day with my new HK450 heli and was doing some pop up when the tail gear assembly slipped sending my helicopter into a wild piro as I was going up, I immediately backed off the throttle and regained a little tail still spinning mad but I managed to land the heli without any damage.

I pulled apart the heli to discover that the tail gear had slipped, so I went about changing the gear but before I did I pulled against the gear to see if I could make it move, well the result was scary, just with finger pressure I was able to pop the gear from the shaft, so I went about getting some green loctite and found that it held perfectly, never to move again, even to the point of using a vice to apply pressure I found that the gear would start to show signs of snapping off but no signs of it moving from the shaft, I then proceeded to fix all my other spares in the same way and recorded what I found which is shown below in the video, needless to say I wasnt the only person who had suffered the tail gear slip, but now everyone is using my fix to the gear and not one person has had it slip since doing this mod.

I highly recommend you do this before you fly.

Turnigy Plush 40A ESC 3A BEC for the HK450 Heli

I was curious about the performance of these cheap ESC’s and pulled it apart only to discover that the ESC was a lot more than I expected.
These Turnigy Plush ESCs are perfect, they use a switching technology to provide the output for the BEC and still call it a linear output, to put it simply it is a buck converter circuit and it is capable of supplying all the current you need for your servos gyro and receiver.

Take a look at the video and see for yourself this is a quality built ESC, oh and dont worry I simply finished off the ESC by putting some more heatshrink back on and it has been flying ever since.
