Bolly Helicopter Products

 

Heli Products have been discontinued.

This page will soon be moved to an "Archive" page.

We have an exciting new product to release ... largely unseen by the Heli world, and a specialty of Bolly's Carbon Composite manuafcturing ..... what is it. Sorry, but you must wait until 2009 for more details.

But first some news, we have decided to suspend the manufacture of the Bolly "Speedrotor" Heli Blades.  To understand more, read the below history of Bolly Helicopter Rotor Products.

 

A History of Bolly (Model) Helicopter Rotor Blades.

In about (we forget) 1980 - 1982 Bolly had developed the World's best Model Helicopter Rotor Blade. It is a tall statement, but it is true. Unfortunately very few people ever got to see it, and due do the complexity of manufacture (no lead inserts were allowed back then), it was uneconomical, and we sold the tooling. We never saw another blade, and unfortunately we never kept a sample. To this day I believe it would hold its own for performance.

We forgot about making Heli products until one of our staff took up Heli flying to become an extreme 3D expert. Still we resisted as the mathematics told us it was not a viable proposition with Australian wages. That was until we had an offer to go to China, to develop a product range there. It was all too tempting, and we did just that.

We deliberately started slow, and through some extensive testing derived at a unique tapered blade design and airfoil that featured on our original 1980 product. It was a real winner, with one of the biggest names in Heli reporting to us the CJ-700M was perfect for F3C. The below list of products was the result from there, with new sizes popping out every month, but ....

Then the carbon fibre crisis hit (world wide shortage), and we had to quarantine our supplies (we needed 1,000 square metres) to ensure we serviced our existing propeller customers. The very first production run was stopped in it's tracks.

But that is not the main reason we have discontinued production ..... the first production run is sitting in a warehouse in Hong Kong (or so it is claimed), undelivered. Why, well you need to ask the ~!@#$%^&* (insert all appropriate swear words for the low life Hong Kong / Chinese businessman who has chosen to "steal" our tooling, materials and stock). Despite repeated promises it has never been returned, and probably never will. The stories of the Chinese shafting westerners can be true, we know it firsthand. Mind you we are slowly getting our own back at the !@#$%^&*, but we won't go into that.

Not to be deterred we have CAD files or Patterns for all these products, and have rebuilt / or could rebuild the tooling to re-commence production. Indeed we have been making Heli product for OEM customers since mid 2006. However, the new product we have been working on has us very excited and is now our priority.

The below products have been suspended from manufacture and sale. 

All Bolly Heli blades are made from top quality epoxy resin, aerospace grade carbon fibres and post cured for optimum strength, stability and durability.

Our core design uses a very low drag but stable airfoil and tapered blade. We do not use fancy paint schemes as the weight of this detracts from the overall strength or weight distribution. Note, the photo's featured on this site are not the same as the production items - which will feature our Speedrotor logo at the tip.

We are however working on an exciting new Heli product that is in testing .... stay tuned.
