I am flying mine with a Thunder Tiger .91 4-stroke. It is lacking in power for sure. I plan to change engines in the near future to a TT 1.20 2-stroke, probably overkill but I have heard alot of good about that engine so I want to get one. The 1.08 should be a good match. I have not used any Magnum engines but I have many A.S.P. engines which are apparently exactly the same as the Magnums, made in the same factory too. The A.S.P. engines are great, very reliable but seem a bit heavy. If you don't mind putting down the extra cash get the O.S. 1.08 that is an excellent engine. Make sure you use decent servos in this thing if you want to 3D.
