Designed and 3D printed in-house by MPM Hobbies, this highly detailed R-3350 radial engine is a resin upgrade part for 1/32 scale aircraft modelers seeking maximum engine bay detail.
This part is a universal upgrade and is not engineered to fit any single kit out of the box. Modelers should reference R-3350 photos and be comfortable with minor fitting adjustments. Severed detail wires can be replaced with fine copper wire for a clean result.
