Hobbyking H4 Quadcopter motor mount repair

Just a quick tip on the fixing the weak motor mounts on the Hobbyking H4 quadcopter, i mentioned it in an earlier article, but thought that i would dedicate a small article on this matter.

I purchased a set of aluminium mounts off ebay at hobbycnc for £9 + shipping, he has the original H4 equivelent in alu, but at the time of ordering, his stock was depleted so i opted for another design, this required that i re-drill the mounting holes on the tube.
The package comes with 16 screws for mounting the motors.

I weighed the original mounts as i thought the alu version would be much heavier.

It turns out to weigh exactly the same 10 grams.
I weighed the mounts for the Hobbyking X60F, which were currently mounted on the quad, they weighed in at 33 grams, so a bit of weight saving can be done here.

Mounting required drilling a new hole through the arm.

Simple.

Mounting the motor was pretty easy compared to the original H4 mounts, the motor aligns nicely and the screws are easily mounted.

Bought some replacement square tubes off ebay, for $8 http://www.ebay.com/itm/300774845368?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 for future needs, in case of bent or broken arms.

Have now had these motor mounts on my quad for about 1 year, they are solid and almost unbreakable, they bent under heavy crashes, but can quickly be straightened with a rubber hammer. They can take a lot of strain from bending and straightning without structure breaching. This is a five star upgrade to your quad.
