Ok well I also will say that I have aTWist 40 3d that was electric with a power 46 and has since been pulle out and put to nitro due to the cost factors in electric. I had over 900 into a 40 sized aircraft after the batteries bec and all the other equiptment. I am not a beginner pilot by any meens. I just think that a trainer should have longer flight times to get used to flying and my opinion for the cost to flight times is nowhere close. Its just my opinion that the nitro is the best to be trained on the you can fly whatever you want. Our club are all firm believers in nitro training and invest later when you can fly.
