RE: Pay It Forward Build Thread!! Sig LT-40 build
With the power options of electric components there is no reason in the world you can't electrify a LT-40. In fact, I think it would be a great combo. The HUGE wing on this trainer will give you ample lift to get the battery in the air. Converting the mount to an electric motor should not present any problems either. The only downside I can think of will the initial expense of the batteries and a charger. If you want to get a decent amount of flights in on a training session you will need a minimum of 2 battery packs and a good charger that can use 12V DC power so you can recharge at the field. But even this will be a bit limiting as each battery pack is going to take an hour to charge. 3 packs and a charger would be what I would go with if it were me.
