Hey guy’s has anyone run the RCMK in there RC boats. I’m thinking about the Sikk motor from DDM and heard about this one comes stock @ 5.2hp and has the same mounts as the Zenoah G260. $260.00 turn key seems like a great deal. You put a 5.2 hp with a wet tuned pipe and were in the 6+ hp zone. That’s when boating gets interesting….. :eek:
 
That'll work......boating's always interesting......right around 40mph is when it gets hairy....depending on the wind and waves.....flipped mine coming out of the hole hot, too much prop wash on the rudder, got sideways, cavitated and flipped....brought her in as quick as I could with her bow 3ft out of the water...must've had 2-3 gallons in her.....oh how I miss her :(
 
getten sideways @ 40mph is hairy for sure. i run the futaba fasst system and had the steering set at 100 and hit a turn at around 40 also and flipped one of my boats:confused: full of H2o got it started pretty quick and saved it:D Scary for a few moments. i want to beef up this 52" WHH man of war hull so that why i'm asking about motors that maybe you guys have used.
