[Manta Ray advice needed]

Cheers chaps, i did wonder if the Top Force would make more sense, maybe just throw a Racecraft body on it and pretend, i am assuming there is someone out there who would make a shorty lipo adapter for it? 

[Manta Ray advice needed]

When we get back racing again i am giving some serious thought to trying some vintage, there is a nice scene in my part of the world, all the usual suspects car wise so i figured why not try a Manta Ray for something different, is this ill advised? My main concern is what batteries you can get in it, am i looking at investing in some old fashioned stick packs if i go down the MR route?
