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.


How to replace model engine bearings



Although modern glow-plug model engines can last almost a lifetime, the bearings in them eventually need replacement.

Sometimes they are attacked by rust or corrosion, other times they might simply be worn out.

The average model engine might turn at speeds of up to 15,000 RPMs which means that in an average year's flying of (say) an hour per weekend, that's a total of almost 50 million revolutions!

It's only natural that no matter how good the bearings are, and no matter how fancy your fuel is, sooner or later, those bearings will need replacement.

Fortunately, replacing those bearings isn't rocket science and can easily be performed by the average modeller with access to little more than an oven or gas torch, a rag or glove, some basic tools and a little space.

Because pictures are worth a thousand words, I've created a couple of videos that take you through the process:

As you can see from these videos, there's not really much to it.

Where to get your bearings

I guess I could charge various bearing-suppliers a lot of money to advertise on this page but instead I'm going to let you in on a secret...

There are plenty of places that will sell you new bearings for your engine at highly inflated prices. Sometimes these companies have very flashy logos and websites that serve to create the illusion that their product is something special.

The reality is that, if you're looking for the best value in model engine bearings then you really can't go past RC Bearings. I've regularly bought my bearings from Paul at and have found them to be far better than those provided as standard equipment in reputable brands such as Saito, Thunder Tiger and Magnum.

Paul's prices are extremely good, his service is second to none, and he is straight as a die. I strongly urge you to compare his prices to those of mainstream bearing suppliers before buying.

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?


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?
