I recieved a twistcarb on my new replacement SH.18 from the Redcat warehouse and when I was told to comeback and get the right one, insteadI was given my old pull carb. and told that they no longer stock the pull carbs and that i could find one online. Breaking in my new engine on my 2 mo old Caldera was a total disaster. I'm switching to EXCEED they have a SH.21 on a 1/8 scale truck for $199.00 and their new .21's are 60 bucks. Redcat has lost my trust.
