the transitions from Left to right are sloppy.... and thats in the hands of a Pro drifter too !

If you do continue to wish to drift, then I too recommend an Electric..
You have to way up running costs VS inconvienience..

1. You have to run the Nitro rich, just to stop it from Blowing the Head.
2. Tyres.. using polypipe tyres on an Electric is fine... but you don't have reverse thrust on a Nitro when things go Bad... you do with an Electric.
so using Polypipe on a Nitro and learning to drift will cost a fortune in repairs..
Nitro's prefer the Hard Compound rubber drift tyres which cost the earth compared to a Metre of Polypipe..
3. Nitro's require tuning... and fuel.. a $20 Battery will out last $20 of Nitro.. so add that to the running costs and drifting an Electric is far more appealing even if you have to walk 200 metres back to the Car to recharge the batts.

Drifting isn't about speed.. Its about loss of Traction with control and kicking that tail out wide and keeping it there.. the Throttle response of a Nitro occurs High up in the rev band, where as an electric has the Power and torque from an instant..making it way easier to learn to drift and giving you a better degree of control...

Consider these options before going nitro for a drifter.. Most guys I know who have had RS4's traded them in on HPI Sprint 2's as they found the Nitro's just cost too much to drift....
