The RD logics is a re-badged Nanda swift. It is actually not too bad but spares can be a problem and with most low budget buggies some problems can arise. Do a search for SHO or swift on here and look at what owners have problems with.
I personaly would go for the Hyper 7 as its the same price, there are tons of spares and hop ups available, Millions of owners worldwide should you have any problems and they are absolutley bombproof (well as near as you can get anyway).
