We are interested in your company making our main blades and we are presently looking at our design again and seeing if it requires modification.
We think that we would like to have your company make some original blades like our design, but we would like your company to advise us about our design and tell us if it is correct , and if it will work well in your opinion. We would like you to give us your suggestions on any improvements to our design, if required.

We will require 2 moulds to be made, 1 left rotation and 1 right rotation. We will then need 3 main blades of each rotation. We require 6 main blades in total. This will be our first order requirement at this time because our helicopter is at research and development stage, but we will need more main blades from these moulds again in the future.

The main blades need to be 1900mm long, chord 185mm, thickness 25mm , but your advise would be appreciated on this matter ; the profile needs to be Eppler 186, the blades will need a +5 degree twist at the root and a -3 degree twist at the blade tip.

Please can you tell us what would be the cost for the above, please give a break down of the costs involved ?

Please let me have your thoughts on the above ?
