Hello
My 10 year old son Otto made me promise to help him build a model to replace his small profile scale Kawasaki Hein Ki61 (with OS 15 ) after I finished my Viking classic stunter before our Nationals on the 3rd of January here in New Zealand. We only had 2 days left for the build after I finished my Viking but he was not giving up!
We used all the tricks we could think of to speed things up including some old Titan combat wing cores for the outer panels and he just cut and sanded the flat inner wing section out of a solid foam slab. Suspended bellcrank with dihedral wing worked out fine. One coat of clear two pack on the fuselage and then Acrylic Enamel paint but this did cause the card covering on the foam to bubble as we did not use oil based paint and did not seal it properly first.
K&B 40 engine with 10x6 3 blade and 2.4 Ghz control of the throttle. He was still painting the canopy on the night before in the Hotel before the event. Other then the Tatone muffler working loose it flew well on the day and he got 4th in profile scale.
I have not flown it yet (yes he did all the test flights) but he is very happy with the way it flies even if it looks a little rough!
Regards Gerald
