I have a Brison 3.2 for power, 1200 NiMH for rx and the same for ign. Motor weight is not really too much of an issue on mine because I am still tail heavy. If my motor was lighter I would still have to add weight. I don't put too much stock in manufacturers weight because they are hardly ever right. There is no way to get this plane anywhere close to the 14lbs that they have listed on the bottom end of their scale. I know mine could be lighter but it would take redoing the plane to get the weight up front.
