Build, shape and firmness the reviewer highlights
The channel describes the Siux Electra ST3 Stupa Pro as a hybrid-shaped racket — essentially a rounded teardrop — with a medium balance. The faces use 15K carbon and the frame is a double carbon tubular, a set-up that aims for stability without adding harshness on impact. The core is noted as EVA Black with a medium response. While many have labeled this model stiffer than the previous ST2, the reviewer stresses it is not excessively hard in play and offers notable comfort for its class.
In short: it’s a pro-spec frame chosen by Franco Stupaczuk, but it doesn’t punish the arm when rallies get long.
Verified specs and small but relevant measurements
- Measured weight: 357 g (brand-stated for this unit: 355 g)
- Balance: 27 cm (medium)
- Shape: hybrid/rounded teardrop
- Face material: 15K carbon
- Frame: double carbon tubular
- Core: EVA Black, medium feel
- Vibration control: ShockOut dampeners installed as standard
The small weight overage is within normal tolerance, and with the protective film accounted for, it’s effectively on spec. The mid balance at 27 cm and sub-360 g build explain the standout maneuverability noted throughout the test.
Volleys and net play: easy acceleration and bite
Up at the net, the reviewer reports an excellent “ball exit” with clean, predictable response. Volleys come off the strings with enough pop to press and finish, while the surface and layup take tagli (slices/cuts) well. The relatively light test unit at 357 g made quick reaction work feel natural, reducing effort on reflex blocks and quick punches.
Comfort is a recurring theme: despite its performance DNA, shock is well managed and the hand stays relaxed through repeated exchanges.
bandeja and vibora: controlled cuts with accessible power
From shoulder height, both bandeja and víbora benefit from the racket’s blend of grip on the ball and stability in the head. The creator points out how easily the Electra ST3 takes spin and maintains line, then delivers extra pace when the swing speed rises. This particular lighter configuration amplifies that sensation: the head moves quickly, yet it does not flutter on contact.
Groundstrokes and lobs show pro-level comfort and control
On basic strokes — forehand, backhand, and lob — the ST3 Pro feels “very professional” without being unforgiving. The channel notes a high level of directional control when guiding the ball, and a clear gear change when accelerating through contact. For players who like to build points with height and depth, the control window is notably wide.
Wall exits: forgiving sweet spot and stable response
On lower wall exits under pressure, the sweet spot is described as “ample, not huge,” with the benefit of tangible stability and practically no vibrations. The installed ShockOut dampeners help mute residual buzz, and the mid-balanced, sub-360 build keeps the racket nimble when feet and timing are late.
On higher wall exits, the frame shows two faces: touch precision when caressing the rebound and easy acceleration when asked to punch through. Even slightly off-center contacts or balls caught too close to the body remain controllable, which raises the overall confidence in defensive-to-offensive transitions.
Smash and por tres potential for aggressive finishers
With proper mechanics, the creator finds the remate remarkably accessible — including the por tres — thanks to the quick head speed and a solid, stable impact. Players who hit flatter smashes are also “accommodated”: there is enough free power on a direct, linear hit to pressure or end points without over-swinging.
Feel and firmness compared with the previous Electra ST2
The reviewer addresses the common narrative that this ST3 is significantly harder than the ST2. His verdict: it is a touch firmer, but not dramatically so. In hand, the feel leans slightly to the firm side while preserving comfort, which is why it suits a wider range of advanced and improving players than the “harder” label might suggest.
Who should choose it and ideal weight range
The channel recommends the Siux Electra ST3 Stupa Pro to intermediate to advanced players who want a fast, stable hybrid with controlled power and reliable spin. One caveat concerns unit weight: he advises avoiding heavier specimens around 370–375 g if you are sensitive in the arm or prefer maximum maneuverability. The sweet spot, according to the test, sits up to about 365 g, with 355–360 g offering the most universally friendly handling.
In practical terms: pick the lighter range for speed and comfort; go heavier only if you specifically seek more inertia and can manage it physically.
Key takeaways from the on-court test
- Net play: quick acceleration, excellent ball exit, clean slices.
- High shots: bandeja and vibora combine spin hold with accessible power.
- Baseline: easy control on guides, extra pace when accelerating.
- Walls: stable on low exits, forgiving on high rebounds, minimal vibrations with ShockOut.
- Finishing: strong smash and por tres potential with correct technique.
- Feel: slightly firm but notably comfortable; not as harsh as some suggest.
For a racket carrying a pro’s name, the Electra ST3 Stupa Pro manages a rare balance: brisk and dangerous in attack, yet stable, comfortable, and manageable across all phases of play.
