I have the carl goldberg .40 size cub and i got a magnum 70 4stroke for it for christmas but i could put the 40 on the cub and the 70 on the dazzler i have been doing the sim for 3d and i am a very fast learner i had two buddy box times and i was already doing rolls and loops and touch and go's so i just need to practice 3d just watching videos and doing the sim. thanks
