exactly it isn't the same engine. and alot of the engines on the market may actually be the ones previous to all the changes, so hence they are for all intensive purposes the old "inferior" design. the kyosho one, being a newly branded crf, has all the good parts/additions. or revisions on it. it is the latest version, ie the best version.

unless you can find a shop of course that stocks the very latest, team orion silver head crf. Unless you can see the product code you have no way of knowing, so a good way of knowing that you have the latest crf, is to just get the kyosho one.

simple. The CRF therfore in simple terms, is a different engine. Many people remember the old CRF as having issues, this is a easy way to dispel the concerns, and make people at ease with the purchase of a new technology motor.
