This is a modified version of the PNP Twist 40 made bigger visually and physicaly with an OS .61 FX. It's setup to fly like my Yellow and purple Twist that I fly. It flies very well. Please someone create the yellow Arf color sceme. Please note that I did not create the plane, so I cannot take credit for that. Original is on the Swap pages, give credit where credit is do, Great job to the creator, Thanks
