FLYING SQUIRREL
PORTO FPVBuilt for pilots who want to fly digital without compromise. Run it on 1S for classic whoop feel and flight time, or step up to 2S when you want the punch. Whether you're bashing around indoors or ripping outside, the Squirrel is built to keep up.

What Makes It Different
Carbon-integrated motor bumpers
Each arm tip has a built-in horn that takes the hit when you crash, shaped to absorb impact before your motor bell ever touches the ground.
1S or 2S, your call
Most 75mm frames pick a lane. This one doesn't. 2S runs on the 2mm frame only. We do not recommend it on the 1.5mm, which is cut for weight, not for the loads 2S puts through it.
Pick your camera, we've got a canopy for it
HDZero Lux, HDZero Eco, Caddx Ant, Pinch, and DJI O4 Air Unit are all supported at launch, with more coming.
A cover that does three jobs
The honeycomb Flight Controller Cover protects your stack, self-locks onto the stack screws, and routes both your receiver and video antenna.
Ducts optional
Want prop guards? The Squirrel supports ducts, worth a look on 2S, where crashes land harder. You'll need to drop to smaller props to fit them.
Direct swap from your current whoop
Already flying a BetaFPV or HappyModel whoop? The Squirrel is a straight swap: your motors, props, and electronics come right over.
Build Reference
Motors
- 1002 (1S), the sweet spot for this frame. Check the mount pattern, not just the size.
- 1103 / 11000KV (2S), the KV the whole 75mm 2S class settled on. 2mm frame only.
- All motors should have a 1.5mm shaft.
Props (45mm, 1.5mm shaft)
- Gemfan 1610-2, bi-blade, best efficiency and flight time.
- Gemfan 1608-3, tri-blade, more thrust and grip.
- HQ Prop 45MM×2, lightest at 0.25g.
Batteries
- 1S: 300–750mAh depending on flying style. BT2.0 recommended.
- 2S: 300–450mAh, 2mm frame only. BT3.0, or XT30 for max current.
