As luck would have it I managed to pick up a new unbuilt Durafly Hyperbipe biplane from RC Trader the other day, so another bipe gets added to the collection.
They were sold by HK about 5 years back and a guy in NSW had purchased one but never built it.
Anyway it duly turned up (undamaged) and has now, in between working on the Archer 650, it been assembled & set up ready for when we can access our flying field again after all this rain finally goes away. It uses an 800 to 1300mAh 3S battery and I’ve managed to find one in my collection here but if anyone has and spare 3S LiPo’s in the range of 800 to 1300 mAh I wouldn’t mind obtaining a couple more.

Hyperbipe repair 2023
After a minor mishap (hatch came off & stabiliser fell out) the Hyperbipe is all straightened out and ready to fly again.
The nose area needed to be removed to allow for repairs & straightening as it was almost turned inside out
however after some boiling water it was almost back to its correct shape.
After some straightening of the motor mount it along with the straightened nose pieces were glued back together and back onto the plane.
All good to fly again (and I taped the equipment hatch in place this time).
Once it has been test flown I’ll repaint the stripes on the nose to replace the water slide transfers that came off during repairs.

Hyperbipe Mods.
The Durafly Hyperbipe is a great little biplane to fly and excellent for practising 3D flying however due to its super lite construction aggressive flying (along with a prang or two) tends to make the plane lose a lot of its original rigidity.
To counteract this I have added a 4mm solid CF rod to the lower wing for stiffness, this has been glued & taped in place between the two aileron servos & close to the COG.
I have also added dyneema braid to tie the top and bottom wings together through the wing supports and epoxy coated the foam supports for extra strength.
The landing gear has been removed as its not needed for either takeoff or landing and a 3d printed block fitted in its place just to give the prop a bit of ground clearance on landing.
The foam battery hatch (lost in flight) has been replaced with a 3d printed version with twist lock to secure rather that the original magnets that failed.
The cheap 9×5 plastic prop has been replaced with a decent Graupner 8×6 which seems to suit the plane far better
Currently painting in all the water transfers that have peeled off in some places and it will be good to fly again.
It may need another CF spar added to the upper wing if I still get wing flutter but hopefully now that the wing supports are much stronger it may not need it.
