Postal Charges

England, Wales & Scottish Lowlands
75 cm items will be sent in a postal tube by Royal Mail. 150 cm items will be sent in a long postal tube by courier - this increases the postal cost.

UK Islands, NI & Scottish Highlands
All items will be cut down to 75 cm length and sent by Royal Mail unless this postal charge is added to the basket.

Europe and Rest of the World
75 cm long items will be sent by Airmail post at low cost. Longer items will be sent by courier - this will increase the shipping charge considerably.

If even numbers of 75 cm long items are ordered we reserve the right to send half the number of 150 cm items to simplify packing.

Wont Fit

Good product. I purchased the 3,4,5 and 6 mm Dia tube hoping that the 4mm would fit inside the 6 mm Dia and the 3mm would fit inside the 5mm Dia but not a chance.

Structural bracing

I needed something that was light but strong to brace the frame of my EDF VTOL and this performs the job admirably. Easy to cut, strong and very light. Ordering was painless, delivery was quick and packaging (Large cardboard tube) was excellent. I'll definitely be ordering CF products from Hyperflight again when I need them.

Carbon Fiber Tubes for added strength

The 4mm Carbon Fiber tubes were the perfect diameter to add strength to the coroplast body of my home-made plane that w use for combat events. The "Hog Wild" plane maker went out of business so have to build our own if we want to continue combat.

4mm carbon tube order

I was looking for somewhere to get some reasonable lengths of carbon tube to strengthen my large quadcopter.

These looked good to me, and at a good price.

The order was sent rapidly, and the quality fine. It did the job admirably!

I'd order again from these guys - recommended!

Speculative purchase since I was not sure the Tube would suit the purpose I had in mind. Ultimately, and after advice from Hyperflight, the Tube proved perfect for my application. Stiff, tight tolerance and looks good
Quick delivery and excellent service.

Good quality ....

Superb quality very stiff tubing. Using it for wing spar reinforcing in a foamy EDF jet. Excellent!

Great product

A great product used for a couple of jobs. I know this is a glider specific site but the pricing on the carbon tube is the best around. I used the carbon tube for fixing a broken kite and for a mast and boom for a model boat for the kids.

The tube is of good quality, stiff and light weight. Delivery was quick and well packaged. You'll need to pay for a 1m tube if you don't want it chopped down.
