The ship, if I'm not mistaken, is tiny and made to be piloted only by the little Utapau guys that refueled Obi's ship... It's not scaled for a large character like a Magna Guard or SBD to sit in it and drive it... At least not that I recall from its description.
For the sake of the discussion, here's the rundown on the P-38 from the "Complete Cross-Sections" book. Of particular note is that, as you said Jesse, the pilot is one of the Utai (identified as "Utai Air Commodore Senin Vant" who "leads the bi-species Utapau Skyforce", possibly implying that the Pauans are also involved in the force). That said, here is the "data file" for the ship:
Manufacturer: Buuper Torsckil Abbey Devices

Dimensions: length 12.7m (41.7ft); width 12.88m (42.3ft); height 2.71m (8.9ft)
Max acceleration (linear, in open space): 3,300G
Max airspeed (in standard atmosphere): 61,000K (37,905mph)
Hyperdrive: class 2; 3,000 light-year effective range
Consumables: 20 days air, fuel, and food

Armament: 2 laser cannons
And before LFL sees me reprinting information from one of their books and sends me a cease and desist order, I recommend everyone go out and buy the "Complete Cross-Sections" book for information on the P-38 and all kinds of other ships from all six films.
