As Mike stated it will do some limited 3D , but you really have to work at it . Get a cheap profile to throw around for 3D . The S.B is a great airplane ,but 3D is not it`s sweet spot.
The OS 110 would be a nice engine , the crank vent to carb should really help on the glow fuel mess. Not sure what they weight , but with a Saito 1.00 , mine balanced with out any additional weight .
If you intend to pound on your Bolt really hard , I would epoxy the servo tray in really good and reinforce the firewall . I pulled the fire wall just about out , hovering and had the servo tray come loose .
