Yet another Mid Engine XXX Buggy

[col1nw3bb]

Hey guys, im new on here. Been out of the RC loop for about 10yrs, recently dragged my old stuff out and am trying to get back up to speed. So i have a XXX BK2 and i normal XXX.

After reading on here about the benefits of mid motor conversions i decided to give it a go on the normal XXX. So far ive flipped the trans and trimmed the chassis. Also ive stiffend the chassis with some metal reinforcing bars and plastic weld (pro stuff thats used to hold car bumpers together).

Ok will get pics up soon but now its question time, excuse the crappy diagrams (and the fact its the wrong side) best google and my paint skills could do. Which one of the following laylouts would you say is best? The advantage to stick packs is my other XXX uses them, but then my rally weapon uses saddle.... I cant see a major difference in weight distribution from either design either...





Cheers
Colin

Cheers i have seen that one before. Have also read that the mid converted cars have a tendancy to nose dive more, so i didnt want to keep the original battery layout, in order to minimise weight over the front wheels.

Neither layout!
Put the esc & rx where you have them in picture 2, but use the saddle layout as per picture 1, except move them to the centreline of the chassis
And then you have a CR2!

Do you mean like this?

If so can you explain the benefit of this design over either of the other two for me? Like i said ive been outta the game a while and alots changed, so i dont just want an answer i want to understand the answer.

I'm not in anyway technical, but I'll try!
I believe it's all about keeping the weight central to reduce roll whilst keeping it as close the rear as possible (but I'm sure someone will correct me if I'm wrong!)

The way you have it shown there is the same as in the Atomic Carbon CR2 & S2, the Centro, the X6 and the new Cougar SV2 - so there must be something good about it!
