problem is, ive had range issues using nimh x8 so i had to use 9x nimh to fix this (i had dead energizers which wouldnt hold their voltage.)

lipo = best option. u could do it if you can cut out that plastic bit and move anything which is housed in it at the moment, u may need 2 flat packs as the pack ive got is like a square (cost $16 from HC)
