...foams are included...weight is listed at about 1675 grams...It is about right...There is nothing OVERLY heavy on it...Design wise it has everything it needs, (albeit no slipper) but there is nothing on it that is over-built...
...The front and rear towers are slightly flexy in stock form...They are quite high, ie mounted low and the towers are high, so its pretty normal for them to flex but they are defintaely one part you would want to strengthen...Rollon carbon / alloy parts
...The outdrives for the front to rear driveshaft are plastic...They are good and strong and no complaints but they would be better in alloy or steel...Perhaps TAMIYA wants us to buy this upgrade too? I HATE 'planned' weak points [>:]
...It is standing up to brushless so far...
