vtx1800,go over to hobby lobby. then find ACTRO brushless motor's. Actro 24-4 will suit your needs and then go to Freudenthaler folding props and pick out what you need
.The actro motors are very high quality german made motors.I seen the same video with the 163 on the train track.Also Joe Nall tape 1999 ,the first plane to be featured is a 108" version Me163
Good luck,stefanP
