[INFLATABLE WHEELS]

Brian,
A short length of plastic tubing, the type used for air retracts is suitable, pushed over the brass tube and lead to a remote schraeder valve will provide the necesary connection for inflating the tyre. These bits are not provided with each set, presumably to keep the costs down but are simple to acquire and make up.
My experience is that, having inflated a tyre, the pressure lasts no time at all, so better to make sure that the wheels will support the weight of the model without having to rely on pressure in the tyres.

[What products would you like to see reviewed?]

David,
How about in carrying out reviews we support our homegrown industries who themselves have supported us over the years? SM Services is one little British company who produce all manner of essential electronic goodies to get us out of fixes - servo reversers, servo slows, landing light switches, glow switches, retract sequencers, chargers - the list is lengthy. Most of these goodies are excellently priced for made-in-Britain products. They usually get passed over as reviewable subjects, perhaps because they are not as glamorous as engines or gyros.
I'm sure lots of modellers, especially those who may be new to the game, think that if they buy a bells and whistle radio all potential problems will be catered for. But what happens when you want to drive each elevator (or flap) with its own servo and having installed them, one goes up and one goes down - yes we've all done it! It may not be quite so easy to connect up the output from the other side of the servo - one of those little servo reversers is the painless answer.
Terry Bowden Rourke (who is absolutely no relation or paymaster of mine) has, over the years, steadily listened to the problems and systematically come up with the solutions.
I think an article or two on the little gems he produces, and the ways to use them, may be enlightening to quite a few readers.
