Yeah the compression isnt the greatest when hot
so it might be worn out come to think of it. I've been around nitros for many years now and this sh.18 has always been a bit finicky,got better after sealing but still a problem child. Thinking a new O.S 18cvrx would make a good bday present to myself
. So far the only problems I've had with this Caldera are the front knuckles (probley the bigger tires and constant crashing) and the engine.
