Just had a very successful maiden flight. Flies a lot like the smaller model, just lots better! 10s lipo, 2940 watts, 18 x 8 prop, auw 6 Kg. Takes off happily at half throttle. Full power is fun! Very happy with this, flying photos to follow.

John, the photo was taken in Tasmania, Australia. Engine failure and subsequent forced landing account for the gorse wrapped around the aircraft. Apart from crop dusting - top dressing these aircraft were also used by the forestry dept for aerial seeding.

The model is built from a short kit by Laser Design Services in the USA. The tail booms are a built up construction of all balsa except for two carbon fibre tubes in each for the pushrods to run in, that also gives some additional strength. The outer skin is 2mm balsa, wetted and wrapped round a broomstick then left to dry. All up weight is 2.5 Kg. It's quite an easy model to fly, just a bit lively! Flying it in a scale manner just requires a series of very low passes although it is quite happy with loops, rolls etc. This one has been used for removing Gorse Bush. Herbicide would have been cheaper!

I took my model to scale day at my club here in Australia, where the full size Airtruks were manufactured, no one knew what it was either!

Hi Peter, Power will be an electric set up, somewhere around 2500 W should do the job. The model as it is at the moment weighs 1.8 Kg, it will be interesting to see what the flying weight ends up at. If it flies as well as the little one I will be very happy! Edited By Richard scarborough on 15/12/2014 08:33:59
