Tarrant Tabor ( world largest aircraft at the time ) had similar features about decade before; http://en.wikipedia.org/wiki/Tarrant_Tabor

This is a fact..my plane was intented to take people on sightseeing and land on frozen lakes etc.

But I got mixed up with lbs and kg when doing the thrust calculation with propeller and engine power. I have a new top speed at 289 km/h (180 mph ).
262 km/h ( 163 mph ) for the 75% power. Even at the economy cruise it will go 200 km/h ( 125 mph ). Well thanks for bringing this up…I might have forgotten the whole project, but now it started to look good again.

:rolleyes:

It also means that it would take 37,5 hours to beat Dick Rutan record from 1979 ( Anghorage Alaska to Turks Island ) using 419 kilos of fuel…leaving just 450 also for the aeroplane to keep it under 1000 kg with 2 pilots ( I may have to modify it a bit …when knowing how tight it goes ).

It is like half sized DH89 in many respect..a tad faster. Wing area per occupant is pretty close too.

Rapide beats all commuters in economy ?

I did some calculations and I figured that only the big jets flying high fully laden beat the economy you get when operating a DH89 Dragon Rapide….all faster prop planes are less economical.

Is there a lesson to be learned from this ?

Thanks..that is a quite a bunch still.
