RE: Savage 3.5 RTR or 2WD alternatives.
You're in the UK, so the Thunder Tiger MAT4 S28 should be available for a good price - in the neighborhood of the Savage 3.5.. It's bigger and has a more powerful engine. Parts are generally cheaper than HPI parts too.. The MTA4 has a reputation for being really tough too.. Look into it.. Thunder Tiger just came out with the new bigger S50 model, so I would guess you can find the S28 for a good deal..
In not MTA4, then get the Savage 3.5.. Those other 2wd trucks are too small..
And electric is like watching an action movie on mute... AND if anything, once you've got a couple sets of good bats, etc...., easily more expensive than nitro...
