Rebound 75 — cinewhoop frame for FPV drones (black)

Twice as long in the air. That is the reason this frame exists. Typical 75 mm class whoops fly on 1S batteries of around 450 to 650 mAh. The battery bay of the Rebound 75 is built for an 1100 mAh 1S HV pack — roughly double the capacity, and therefore roughly double the flight time, without moving up to a larger class.

Then there is the battery swap: push the clip out from above through a slot, change the pack, push the clip back in. No hook-and-loop strap stretching out over time, no fiddling between the ducts. Fly longer, swap faster — that is what this frame is built for.

Enclosed ducts, not prop guards

The Rebound 75 has four fully enclosed ducts rather than open prop guards. The propellers run inside continuous channels instead of merely sitting behind individual bumpers. That is the classic cinewhoop shape: at home indoors and when filming close to people.

Annealed — the benefit and the cost

Every frame is baked in the oven after printing. This annealing makes it noticeably stiffer and more dimensionally stable. The benefit shows in propeller protection: the ducts flex less under load, so the props take far less of a hit on impact.

The honest flip side: a stiffer frame absorbs less energy through deformation and breaks sooner in hard crashes than an unannealed one. That is by design — the frame is the inexpensive wear part that protects motors, props and electronics. A replacement frame costs a fraction of a set of motors.

Specifications

• Class: 75 mm whoop / cinewhoop

• Weight: approx. 12 g (frame)
• Propeller protection: four enclosed ducts
• Battery bay: for a 1S LiPo of 27 × 57.5 × 8 mm — sized for 1100 mAh instead of the usual 450–650 mAh
• Battery retention: push-in clip, released from above through a slot
• Motors: 1102 whoop motors
• Post-processing: oven annealed
• Colour: black

What you get

• 1 × Rebound 75 frame (black, annealed)
• 4 × battery clip — it is the part most likely to go missing, so four come in the box. Need more? Select above; each additional clip is 0.50 €.

Motor screws are not included. If you are moving the frame onto an existing build you will usually have them already, so you do not pay for screws that end up in a drawer. If you do need some, simply add them above: six for 1.00 €.

Electronics are not included either — motors, flight controller, camera, VTX, propellers and battery come from the build of your choice. The photos show a fully assembled drone to put the frame in context; what ships is the printed part together with the clips.

Components that fit

The drone itself is a DIY project and a good starting point for newcomers to FPV. This combination has proven itself:

• Motors: BetaFPV 1102 13500 KV
• Battery: GNB 1100 mAh 1S 60C HV — the large pack the bay is built for
• Charger: VIFLY WhoopStor V3 (1S)

Please note: we print and anneal this frame and ship it ready to use — it is not a printable file for you to make yourself.
