This is my fourth time visiting there with the club and it is a good day out. Along side the model show, there is a military vehicle show held next the the shows marquee where you will see many different types of military vehicles on show. The entry fee covers you to visit the model and military vehicle shows, but also the aircraft display halls and the tank museum which are part of the IWM Duxford.
It is a full day when you visit this weekend, but it is well worth the money spent. Adults entry is £17.00, but under 16's get in for free. The kids will love it, my grandson did last year, especially the tank ride and climbing inside a few of the aircraft on display (even managed to get in one closed to the public). But don't take my word for it, check out the links below and the video of some RC Tanks and the Armoured Personnel Carrier used for the tank rides.
