Newb, in terms of adequate power, any modern ball-bearing .46 will have more than enough (Super Tigre included). I suggest that you buy one that you can afford & that you can live with easily.

In my opinion the the Winners are: TT .46 Pro (possibly the best all-around .46 sport engine on the planet) & OS .46 AX (another really good engine, but I'm a bit anti-OS at the moment).

Second tier sport engines: Evolution, LEO, Magnum, Super Tigre, & MECOA -- all good, but can be a bit fussier to live with.

Third tier: GMS, Tower -- based on Super Tigre designs, they are powerfull, but can be frustratingly troublesome.

Don't bother engines: MDS, VMax


These are my own personal opinions based upon direct experience, or direct observation. Undoubtedly there will be many more opinions out there.
