RE: Crawler or LiPos?
the dynam "icanfly" from nitro planes is great for the price. was my 1st 4ch plane. $120 shipped, RTR with brushless running gear. 3 foot'ish wingspan.
I love my axial scx10, and I have had a ax10, wheely king, rs10 ext. I have had a couple of mini crawlers thinking that indoor crawling would be fun. Well, for me it just wasnt.
If you want to try rock crawling, save up for a 1/10. the exceed 1/10 or the redcat rs10...both are OK for the money and can be made into decent rigs with alittle modding and not alot of extra money.
