Default Adjustable pitch Prop

Hello, i've seen some years ago in one on my magazine, a prop manufacturer which made multiblade prop in plastic whith a metal hub. I don't remember their name at all .. it's not soloprop i think it's a german manufacturer.. Can you help me please?

Default RE: Adjustable pitch Prop

Check the classic pattern section; do a search there. There are a couple of threads in that section.

Ramoser Varioprop
  • 2, 3, 4, 5 blade adjustable pitch props
  • Righthanded or lefthanded
    (note that CW/CCW and pusher/puller are not prop properties)
  • Scale blades and adjustable folder hubs too
  • 5,1" to 31,3" prop diameter
  • Electric and IC versions
  • Replacement per blade, not per prop
Either direct order or e.g. via www.aircraft-world.com

Note that changes in setup can have surprisingly considerable/huge effects.
Always check current in a new/changed setup!
Motorcurrent drawn is proportional to pitch¹, voltage², Kv³ and diameter⁴.
Power-drawn is proportional to #blades, pitch¹, voltage³, Kv³ and diameter⁴.
E.g. doubling voltage will four(2²)fold current, doubling Kv will eight(2³)fold current and doubling prop diameter will sixteen(2⁴)fold current.
