Default RE: Engine Size Recomendation?


ORIGINAL: altavillan
It would be interesting to know if a fullsize top of the line aerobatic airplane can hold a KE pass indefinately. I am pretty sure they couldn't just a few years ago. Not untill they were allowed to hop up the IO 540 over about 330 HP.
Nope
Full sized Extra 300 series ("L" configuration) fitted with original IO540 - definitely not
Same plane - retrofitted with Thunderbolt Engine upgrade (330 Hp version of the I0540) and MTV 9-B-C/C200-15 Prop - not indefinitley but certainly for a lot longer.

But then again - it doesn't prop hang, torque roll or have unlimited vertical indefinitley either. Fast rolls around any of the Axes and spins are good fun though

Pilot weight - a little over 125kg. - Aerobatic fuel plus about another 20 gallons on top.
