Believe It,This is the motor I'm ordering form them too.It has more power and higher rpms too.then my .21.My .21 is the older model.The 7220m is the newer model.Its 65 dollars shipping is 10 dollars.I'm waiting to here from them.I'd emailed them about two days go.The exaust is side mount.I'm not saying there the best motors on the markets but the way I rev that .21 before I put my boat in the water,I'd should blowend the conecting rod by now.I do some guick revs to clean the carb out before I throw her in the water.I inspect my motor every fith run.No sighn or cracks or anything wrong.I does have a heavy conecting rod.I'm new the nitro motors and if I'd blow it up or recked it,What! I'm out of less then a hundred dollars! then being out of 300 to 500 dollars!Unitl I'd mastered in them realy good,Then I'll get the 300 to 500 dollars motors.
When I hear from them I'll let you know.[8D] I did get a marry christmass email from them.
