detail Feb 1990 column particular column brought lot reader comment especially regard products market billed trainers Sometimes suitability term grave doubt Personally Ive always held Basic TrainerElectric otherwiseshould model design having inherent stability no ailerons moderate power Well folks has just occurred Vintage planes Ive described above Beam Esquire exactly Seniorita Dont misunderstandIm advocating re-introduction outdated control systems Rather Im suggesting representative models airplane designs exactly what feel basic trainer should equipped modem radio particular Beam Esquire represent model designs capable sustained stable safe flight themselves because day radio control often off condition Some have described RC early days free flight occasionally interrupted radio mis-control case regrettable similar designs days past no longer kitted Continued page 133 128 Model Aviation RC Electrics/Kopski Continued page 128 leads propose true test model design contemporary otherwise determine whether qualifies basic trainer wet must successfully fly rudder-only escapement Id allow MC safety too Such test would surely separate designs really basic trainers claim Now didnt someone think before Manufacturers take note Ah Finally Truth advertising new Astro Connector mentioned last month best can recall makes fifth connector variation Astro has used over its twenty year history very first Astro connector no connectorjust wires emerging battery motor Shortly afterward Astro incorporated large Molex two pin connector followed smaller Molex version soon followed gold-plated variant proved woefully inadequate Astros motor line gradually developed impressive powerful product array today As growth taking place Astro began using Tamiya-style two pin connector popularized RC cars serious Electric modelers routinely used Sennos connector system instead new Astro connector appears significant upgrade over earlier Astro connectors As shown
