Charlie, any i/c model, except extremely large ones, may be converted to electric.
The "works" TSUK Telemaster 40 was powered by a 3547/800kv electric motor fitted to a 13x8 prop and 60 amp speed controller, powered by a 4s LiPo. I used a 6000 mAh LiPo because I used the model to train beginners and wanted to be able to fly for 20 minutes at a time. A smaller cheaper 4S battery should suit you. What this means, if you are a novice to electric flight, is that the motor is 35mm in diameter and 47mm in the length and that 1 volt will turn the shaft at 800 rpm.
This sort of set up will suit an LT40 or Senior, the smaller Seniorita will suit a 3542/100,12x6, 45 amp speed controller and 3S LiPo. Picture of "works" TSUK Telemaster 40 below. Of all of the Telemasters the electric T40 was my favourite. Flaps are not essential.
What are they flying as trainers at your local flying club?
