Thinking back to my gliding days, where you have very simple control surfaces - rudder on the tail and ailerons on the wings.

If you tried to turn using the rudder alone, you pretty much just carr ...

Ah, I see it all now Idea

Simplistically, the control surface on the front provides (say) lift and the fins at the back hold the back down causing a rotation force through the centre of mass thus ch ...

Part of Newton's first law states that 'An object that is in motion will not change its velocity unless an unbalanced force acts upon it'. Surely it is because the steerable front or rear fins cause a ...

In the nose, a GPS receiver and computer controlled aerodynamic directional fins keep the round on its programmed trajectory. Folding fins in the tail provide stability.

That makes perfect sense an ...

Then how on earth do laser guided smart bombs with steerable tail fins work then?

By having support control surfaces on either side of the centre of mass.

I can't for the life of me see how it works.

If it is a standard mortar shell then how can it control its trajectory once it is out of the launching tube?

"The GPS and an accompanying computer c ...

The 10AW is plenty big enough. The one that I have is exactly the right height, the zip does up easily. Width-wise it is a bit wider than the A10, which lets you get your fingers down the sides to l ...

I have Zagg protectors on several devices, including cameras and a pda and I have never had any real problem in applying them following the instructions given.

I took the outer cover off my Satmap ...

I watch it, but only from a recording, so that I can fast-forward through the rubbish bits (of which there seems to be a lot more lately).

Thanks Robert - I think we may be in danger of confusion, but perhaps it is only me . . . . Laughing

A 1:25000 map of Jersey is available on paper, published by the States of Jersey, Planning and En ...

We did some walking on Jersey recently (Channel Islands that is, not N.Y.) and I looked for a Satmap map before we went, but couldn't find one, so I left the A10 at home and used 1:25000 OS type map. ...

It looks like the "Options" in the new SatSync version released today my fix this problem.

Yep - I take it all back - have just loaded the new version and at first sight it works perfectly.

Exce ...

Yep - I checked mine carefully this evening and I get a very similar effect.

The Satsync screen shows the route name alloted to the imported file, but on the Satmap I just see "Route name". If I i ...

I have had some problems with Satsync, but assumed that as a new boy I was just being incompetent . . . . . Shocked

I'll have to make better records of what happens next time.
