Punctilio Props

 Back to home page
 
We use the same timber, materials and attention to detail for the Smart and Airflow ranges as is required for props that are used for Target and Surveillance drones - smaller ones do, in fact, 'use off the shelf' Airflow propellers!

World wide, very few manufactures can match our experience!
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

These are what we are famous for!

All our props are made from European beech wood on our purpose own designed machines to ensure accurate machining and consistency of performance. Once made, each prop is hand finished and sprayed (sanding between coats) with a fuel resistant, protective clear lacquer.

We make two different shapes;

  • Airflow - These are our original square tipped two blade airscrew. Now with yellow tips for better visibility.

  • Smart - This is our scimitar blade airscrew producing equal thrust with slightly lower tip noise.

NOTES ABOUT GETTING THE BEST RESULTS OUT OF YOUR AIRSCREW

Balance: There are several differing opinions about the way to balance. Some advocate sanding the front of the heaviest blade so the back and hence the pitch is not altered, others suggest only sanding the back so the front airfoil section is retained

Both methods will necessitate the blade to be re-lacquered. We at PUNCTILIO are rather lazy and like to keep things simple -

Lightly sand (fine garnet or wet & dry) the lightest blade or rub with fine steel-wool this gives a key for a Two-pack fuel proofer and coat until balanced - simple and neither the section or the pitch is seriously affected.

Even simpler is just to apply a coloured tip as on our AIRFLOW pattern.

Remember

Wood is compressible, when tightening onto your motor shaft, so if you leave the airscrew in-situ check for tightness before flying, better still remove it when you pack up there is also less chance of it getting damaged - many an airscrew has been knocked and sustained a crack at the hub inside the spinner

We only supply airscrews with the single hole but as our hubs are substantial they will accommodate drilling for multi stud fixing, in our view a single nut attachment to the motor shaft is rather ambitious for the larger and powerful engines now in use especially when opening the throttle sharply. If you need to drill out or bush aim at a smooth sliding fit - not loose and never tight.

TAKE EXTREME CARE WHEN OPERATING AND KEEP SPECTATORS WELL AWAY - THEIR SAFETY IS YOUR RESPONSIBILITY!

DO NOT WEAR SCARVES, TIES OR LOOSE FITTING CLOTHES
