I've got a HPI Savage 21 with an OFNA .26 motor in it... haven't ran it in a long time but that thing was insane... Ran over curbs AT full speed like they were nothin'.. Last time I drove it we had setup a skateboard ramp against a dumpster... it was atleast a 45 degree angle.... that thing went ATLEAST 35 feet in the air and landed so perfectly... It's just too bad those things are so damn expensive... i got $700 invested in my one r/c..
