DolphinRC PRISMFLY X2 — A Tiny Frame That Skips the Soldering Iron
A 115mm 2-inch combo kit with a built-in ELRS receiver on the flight controller, so binding is the only setup step before you fly.
Is the PRISMFLY X2 worth buying?
For a 2-inch micro build, it's a genuinely convenient combo — the BETAFPV F4 20A AIO stack has ELRS built in, so there's no separate receiver to solder on, which is usually one of the fiddlier steps on a build this small. At 79.7g without battery and a 3S 450-650mAh recommendation, it's positioned as a light, punchy micro rather than anything long-range.
A micro frame that leans on integration, not add-ons
The PRISMFLY X2 pairs a hybrid carbon-aluminum 115mm frame (3mm carbon plates reinforced with 4mm aluminum) with RCinpower GTS V3 1203 8000KV motors and a BETAFPV F4 20A AIO flight controller that has a serial ELRS 2.4G receiver built directly onto the board. That integration is the headline feature — most small builds still require binding a separate receiver module and soldering it in.
What makes it stand out
Built-in ELRS — no soldering required
The BETAFPV F4 20A AIO stack includes a serial ELRS 2.4G receiver on the board itself, so getting this in the air is a binding process rather than a soldering job — a real time-saver on a frame this small where solder points are tight.
Hybrid carbon-aluminum construction, 79.7g
3mm carbon fiber plates reinforced with 4mm aluminum keep the 96×96×34mm frame light (79.7g without battery) while adding some crash resistance that pure carbon frames this size often lack.
RCinpower GTS V3 1203 8000KV
DolphinRC notes hovering throttle as low as 30% with these motors, which points to a reasonably efficient, responsive setup for a 2-inch build rather than one tuned purely for top-end punch.
BNF kit with two propeller sets
It ships as a BNF (bind-and-fly) drone with two sets of Gemfan 2023-3 propellers included. A 3S 450-650mAh battery is recommended but not included, and no FPV camera/VTX system comes in the box.

Pros & Cons
Pros
- Built-in ELRS receiver removes a soldering step that's genuinely fiddly on 2-inch frames
- Hybrid carbon-aluminum frame adds some crash resistance at a light 79.7g
- Motors tuned for efficient low-throttle hover, not just top-end speed
- BNF configuration means less setup than a full component build
Cons
- 3S 450-650mAh power range means short flight times compared to bigger frames
- No battery, FPV camera or VTX included — budget for those separately
- Small 2-inch frames are inherently less forgiving of hard crashes than 5" builds
- No independently verifiable customer review data on DolphinRC's own listing

A convenient, well-integrated micro build
The built-in ELRS receiver is the standout here — it turns what's usually a fiddly soldering step into a simple bind. Just go in knowing this is a light, short-flight-time 2-inch platform, not something built for range or long air time.
