RE: Would this be a good field box?
I think I understand you are buying this through your LHS. If so, see if they will swap the starter for a higher torque version of the same starter: Hobbico TorqMaster 180. The extra power will come in handy some day and it is only a few dollars more. The HobbyTown here has done this for several local new fliers.
Oops, that was Derek who bought local. Have you checked your local LHS? Sometimes if you show them Tower prices they will match them to get the sale. Asking is free and it shows them that you want to support them too. Saves shipping charges but adds taxes.
