hi,
as my current brushless buggy (low budged german brand ansmann virus w. truggy tires) was in a bad condition and also required some new spares, I decided to do it all new. I am on a budget at the moment, so I got some spares on ebay uk for a hyper7 buggy. These spares are much better in quality then the ansmann-stuff. These parts fit perfectly, and shipping to Germany was cheap.
I have already diffs of the hyper 7, so I now got myself the rear suspension, front/rear bumper of hyperST, center-diff holder, new chassis, front shocks.
The rear shock-tower is made of 5mm epoxy, the front is a sandwich of gfk/cfk and has already proven very rigid. its actually rock solid and survived all crashes, the alu-thing on it is like a skid-plate and protects it. The rear one is 2 grams lighter then the original (weak) one made of aluminium.... wow ;-).
things that have proven to be rigid or useful are also used in the „new“ buggy. The hole for the center diff in the chassis I have glued with a piece of aluminium.
The steering servo will hold the esc, like that I get mass to the front. Worked well so far. I made a kind of top-deck to keep it stable. It's made of 5mm gfk. A little torsion might be possible, but it's stable. Like that I have enough space for the esc in the front and for the motor.
behind the black cfk in the middle you find the center diff, along there it will be the position for the lipo. it kinda leans on there...
I want to keep the center of gravity as low and central as possible. It's all pretty close together, but it worked well so far. Further the solutions have to be simple and stable.
I will use 5s lipo on the 1700kv losi, w. a modded cheapo-200a esc.
To be continued.
