Thanks Trashcar for confirming the spring order.
HarkonnenD about those Novamega engines I can not really say anything yet. It's my first 1/8the car (I also run electro cars) and I can not compare the power to another engine. For me it is plenty fast for the moment and the car runs great.
I do know the engines have the reputation here to be a little difficult to tune. For the moment after 3 liters of nitro gone through, no complaints. The car starts beautifully and runs without problems. In a few weeks I am going to compete in my first race and then I will now more.
I am going to buy a higher priced Novarossi motor in the future which will only be used for racing.
You can not beat the price of the Novamega for practice though. If it holds up, it is a great engine for that price.
In respect to roll center I found a great article here
