Written by: Jeff Eveleigh

We fire up X-Dyno to get some hard numbers on the Reedy VR-ST .21 nitro mill. Former factory Yamaha Supercross mechanic Brian Kinney is at the controls hacking out a perfect tune and maximizing output. BK has also designed nitro engines for the RC hobby and really knows his stuff. Check out the full Reedy 121 engine review with dyno charts and graphs in VRC_004. The dyno info in this video wasn’t maximized yet, below was the strongest pull we got out of her:

Final X-Dyno Data
HP: 1.30 @ 24,300rpm (peak corr. hp)
TQ: 55.42 @ 23,900rpm (peak oz. in. tq)
Peak Dyno RPM: 43,000 (peak rpm measured)
Low Avg HP: 36.07/.58 (oz. in. tq/corr. hp)
High Avg HP: 31.53/.86 (oz. in. tq/corr. hp)
