Default Cargo plane - Twin engine project

This winter is creating a build frenzy ....

I've built the Mosquito ... then the Vulcan ...and now I want a cargo twin to do candy / poppy drops. A C130 / A400 style would be fine - but they are 4 engine jobs ... I have a couple of small 930kv motors that I reckon a 1m span Hercules style could do.

Sketch out plans :





Cut the parts



Lite Ply source for strengthening formers



Sides and formers ready



Gluing up





3D print some motor cowls



fuselage continues



Basic wing cut and checked ... will be flat bottom wing with curved top sheet added



Testng ideas for wing spars ..



She will have servo operated cargo door at rear .... flaps ... and the usual 4 other ch's ...and I will add a Stabiliser Gyro to give me slow capability for the 'show drops' its intended for.
U/C will be like the C130 ... twin outer wheels on fuselage and a front steerable. All fixed ...

Initially it was just an idea ... but once I started - the bug has bit deep !

Just sorting out how to mount SS3 tag for video recording.And wait weather of course.

The 8x4.5 props ..... 3S 1800 = 18.5A ...... WOW !! Pulls vertical ... on 2S 3000 = 11A and decent pull and of course nice long flight time.

Braved cold blustery wet wind ...............



The 2S on the 8x4.5x3 proved only just able to fly with this wind ......so I have now swapped back to the 9x4.5x3 props as I want that weight of the large 2S pack in there.
