Reinforcement

Opened fuselage hole of Kyosho Sonic Acro 160 was reinforced with 5 by 5 cypress wood rod the other day. This kind of arrangement is an indispensable measure to establish enough physical strength as a maneuver model. Though some increase might be happen if this kind of modifying is performed for the convenience of Li-Po battery replacement, we must keep in mind that the lighter the better for any airplanes so far as the physical strength should be obtained because it is in the air.
