My Credentials
So who's doing this reviewing then?

Well I've been building and flying or driving radio controlled models for over 40 years and during that time I like to think I've built up a reasonable amount of knowledge.

I'm also a qualified electronics engineer who has worked in radio frequency, analog, digital systems and software for more than three decades. In fact I designed and built my first RC set back in 1969.

For the past nine years I've also been involved in the design and manufacture of some rather sophisticated engine technology and UAV flight control systems.

So, chances are I've been there, done that and have a huge pile of tee shirts to prove it.

Right now I'm heavily into 3D flying and enjoy all aspects of the RC hobby. I may be old but I don't feel it.

In the Pipeline

Here's just a little bit of what's to come on this site...

RC explained: Demystifying terms such as PCM, PPM dual conversion, single conversion, full-range etc., this feature will explain it all.

Cheap Chinese Engines: Just how good are those cheap Chinese glow and gas engines that sell for half the price of their "brand-name" equivalent? I put several to the test.

Build your own radio gear?: Back in the old days, building your own RC gear was not uncommon and now the arrival of 2.4GHz has made it practical again.

 

Hobby City stuffs up HXT 9320MG Servo supplies

CUSTOMERS NOT HAPPY

 

27 June 2008
The Chinese-made HXT 9320MG servo has proved to be very popular, and one of the cheapest places to buy them has been Hobby City but the current batch of these servos is nothing like previous ones and that's got customers mad.

The servos currently being shipped are nothing like the ones currently advertised on the Hobby City site in terms of power or precision.

Previous samples of this servo had a ball-bearing output, a torque that is very similar to a servo twice the size and more than acceptable precision and centering. The ones currently being shipped are nowhere near as good and appear to be a completely different servo, using far smaller gears (as can be seen in the picture below) and having far less than the rated torque.

One, less than happy customer says "I sent my five servos back to hobbycity.com and told them I DO NOT want a replacement of the SAME SERVO. These servos are no good. THE WHOLE BATCH IS NO GOOD."

Another claims he "received two HXT 9320MGs today and tested them. Both are faulty with centering problems. When left idle, the servo seems to have a life of its own and drifts away from center. I will be returning them. I too do not want replacements of the same unit."

A customer from Sweden posted this video to YouTube, showing the terrible precision and centering of the new batch:

Even the servo case on this new batch is significantly different to the original ones, leading some to speculate that Hobby City may have changed suppliers or opted for a cheaper servo to sell under the same name. However, it would not surprise me if the manufacturer has either shipped the wrong product (please put some damned labels on these servos) or decided to cut costs and re-design this servo using cheaper parts.

Whatever the reasons, the message to Hobby City customers is clear: do not order any HXT9302MG servos until the cause of the problem is determined and there are guarantees that you won't be shipped these decidedly inferior and seemingly defective servos.

Here's a blog that will keep you informed just what's going on behind the scenes at RC Model Reviews and also tells you a little more about myself.

How compatible are 2.4GHz RC systems?

23 Mar 2010
How come there's no compatibility between different brands of transmitters and receivers? Why can't you use a cheap Chinese receiver with your Futaba FASST radio?

Chinese Servos - How do they stack up?

Servos

The Chinese are now churning out a huge number of very reasonably priced no-name servos. But are they any good?

Baffled by batteries?

Batteries Nicad, NiMH, Li-Ion, LiPoly, LiFePO4, A123... the range of different battery types has never been greater. So how do they differ and what type should you be using?
