Hello Simon I think model planes are a personal choice and your dad will like somthing different than you. Also, choosing should be fun and half the problem if shared with your dad. I remember starting on a 0.15 IC powered glider, and have trained new members with electric gliders. But I recommended to join a club and IC powered models are not park flyers. Also you will need insurance for IC engine models and I would recommend it for electric! If you want to make a surprise of it, then get a "BladeRunner II" or a "Micro Mosquito" they fly in the house and cost £69.95. No insurance needed, no club needed, no building, and you can both take turns. Search and see the web videos. That's father-son bonding.. :-) You will realise that model flying is great fun. Get him membership at a club is the place to start. Join the BMFA for insurance. A good club will usually have a free trainer to learn with. ie someone will give you an old trainer they no longer want. email me if you need more info.. Take Care Andy
