When i purchased it was second hand and i rebuilt it with the mid44 chassis .
You dont have to go that far , ive fitted the 4mm thick Atomic carbon front shock mount .
Also the Associated Lipo holder in cf. I run the Reedy saddle packs as they fit nice an neat .
I believe the Vampire range are pretty much the same size and a tad cheaper.
Motor selections up to you i run a Lrp x12 6.5 which is plenty fast with the lipos.
Hope that helps.
