Havent even seen a venture, but the Raptor seems to be fully capable, easy to work on, easy to get parts for, stable... I've been very satisfied with my R39, so i decided to get an R50 too. If i had it to do again i think i would go with the 50 from the start. It comes as a kit only so if you chose the R50, the Arf vs Kit decision is made for you. There are lots of upgrades available, but i hear they only make a small difference. I'm just going to built it and fly the heck out of it. no upgrades needed.
