Two kit built radial powered Waco biplanes

[clare_grace]

The yellow Waco built and flown by Greg was built from a Barth kit (Germany) and the other Waco was built from an American AMR kit at the same scale. They weigh 23kg and the 29kg respectively and both are powered by Blackstar 250cc 5 cylinder 4 stroke radials from Tomahawk Aviation throwing 32x16 propellors. Both Wacos use Futaba radio with Powerbox sbus systems for guidance.
