SURPRISED about the questions around the large holes in the bottom of the fuselajes in ELECTRICs
they are purposefully designed to eliminate the progressively expanding hot air that may accumulate
off motors/ esc s / batteries etc.
They have ABSOLUTELY no bad effects on flight and/or performance.
Enclosed pics taken on this T-34 I just finished for my student (the one who DISSAPEARED into thin air
and has never been heard from since)
Anyone care to BUY a T-34 ?- this plane becomes my property (thru abandonement) in 2010 - HA !
