The Redstone IV is the fourth generation of Hirostar's control diamond and the 2027 replacement for the Redstone. It is the twin of the Blackstone IV — same mould, same 18K carbon face, same new Multi-EVA core — with the weight kept in the hand instead of the head, which is unusual for a diamond. It is on pre-order in Australia now (RRP $485), with our first stock due in late November. This guide covers the verified specs and weight, what changed from the previous Redstone, how it compares with the Blackstone IV, and who it suits — with live prices on the cards below.
The short version

|---|---|---|
| Shape | Diamond | Diamond |
| Balance | Mid-low | Medium-low |
| Weight | 360–375g | 365–380g |
| Core | Multi-EVA (layers of different densities) | Black EVA 17 (single, medium density) |
| Face | 18K carbon | 18K carbon |
| Finish | Fully sandblasted face, with 3D and gloss details | Sandblasted face with a gloss logo |
| NFC chip | Yes — authenticity and warranty | No |
| RRP | $485 | $485 |
| Who it is for | Advanced players who win points with placement and fast hands and want a diamond that does not feel head-heavy. | The same player, who wants one today and is happy with the older core. |
The one-line answer: if you build points rather than blast them, play on the right or simply want a diamond you can swing quickly at the net, the Redstone IV is the Hirostar to look at. If you finish points overhead and want maximum weight behind the smash, read our Blackstone IV guide instead.
What's new in the Redstone IV
Hirostar list four changes for the fourth generation, and they apply to the Redstone IV and the Blackstone IV alike.
- A Multi-EVA core. The previous Redstone used one rubber, Black EVA 17, a medium-density foam. The IV layers rubbers of different densities. On the Redstone, Hirostar pitch it as soft and precise on touch shots and explosive when you accelerate — which suits a racket built for placement more than power.
- A wider, more consistent sweet spot. Hirostar and their Australian distributor both describe the IV as more forgiving than last year's model. For a control racket, that means fewer balls dying off the edges and more landing where you aimed.
- A fully sandblasted face. The hitting surface is now rough all over for grip on the ball; on the previous model the logo area was gloss. Hirostar describe the overall finish as sandblasted, 3D and glossy surfaces together, so the frame keeps some shine where it does not touch the ball.
- An integrated NFC chip. Tap a phone on the racket to confirm it is a genuine Hirostar, activate the warranty and reach Hirostar's digital platform. Handy if you ever buy or sell one second-hand. It changes nothing about how the racket plays.
The bridge keeps its precision openings, which Hirostar say channel air through the heart of the racket while the Multi-EVA absorbs the vibration that is left — less stress on the arm over a long match. What has not changed: the diamond shape and the 18K carbon face.
Weight and balance: how heavy is the Redstone IV?
Hirostar list 360–375g. That is a published band about 5g lighter than the previous Redstone's 365–380g, though individual frames of any brand vary by around ±10g, so do not expect to feel the difference on its own. The balance is what defines this racket: Hirostar list it as mid-low, so the weight sits towards your hand rather than the head.
That is rare on a diamond. Most diamonds are head-heavy because the shape exists to add leverage to the smash. The Redstone keeps the diamond's high sweet spot and attacking geometry but moves the mass back, which makes it quicker through the air, easier to manoeuvre in fast exchanges at the net, and kinder on the arm than a head-heavy frame. The cost is less weight behind the overhead. Racket weight and balance explained covers the trade-off, and round vs teardrop vs diamond explains what the shape itself does.
How it should play — and what we can't tell you yet
No independent review of the Redstone IV has been published, and we have not hit one: Australian stock lands in late November. Everything in this section is the manufacturer's description plus reasoning from the specification, and we will add on-court notes when the first frames arrive.
Hirostar call it "the most precise soul of the PRO line". The previous Redstone was built around the same idea: Padelspeed's spotlight review summed it up as "attack plus manoeuvrability" — the attacking geometry without the slow, head-heavy feel. The IV keeps that recipe and adds the two things the old frame was weakest at. A multi-density core should soften touch shots and blocks without dulling the response when you accelerate, and a wider sweet spot should make a quick, low-balance racket more forgiving on the mishits fast exchanges produce. Whether the IV delivers that is what an on-court test will tell us.
Redstone IV vs Blackstone IV
The two IV rackets are twins: same mould, same 18K face, same Multi-EVA core, same weight band, same NFC chip. The difference is where the weight sits. The Redstone IV's mid-low balance keeps it in the hand for speed and precision; the Blackstone IV's high balance puts it in the head for power overhead. Hirostar sum the pair up as precision and power.
- Choose the Redstone IV if you play on the right, win points with placement and volleys, defend a lot, or want a diamond that does not feel head-heavy.
- Choose the Blackstone IV if you play on the left, finish points overhead and like a racket that feels substantial through the swing. The Blackstone IV guide covers it in detail.
Redstone IV vs the previous Redstone
The previous Redstone is Hirostar's 2025 mould, carried unchanged into the 2026 catalogue — it is the racket most searches for "Hirostar Redstone 2026" find. It is still in stock with us (RRP $485). It shares the shape, the 18K face and the low balance, and differs in the single-density Black EVA 17 core, the slightly heavier published weight band and the lack of an NFC chip.
Buy the IV if forgiveness and comfort matter to you or you want the newest frame. Buy the previous model if you want a Redstone on court this week.
Who should buy the Redstone IV
- Advanced right-side player who builds points: yes — this is its job.
- Left-side player who values speed over raw power: yes, if your overhead is about placement rather than hitting the ball out of the court.
- Strong intermediate moving to a diamond: one of the friendlier diamonds in the range, because the low balance forgives late preparation — but it is still built for advanced players. The Horizon is Hirostar's step-up diamond for improvers.
- Elbow or shoulder trouble: a better bet than any head-heavy diamond, but a round frame is kinder still — the Solar is Hirostar's. Padel and tennis elbow sets out what gear can and cannot do.
- Not sure whether you want power or control: read control vs power, or let the racket finder score the options against your game.
Rivals worth comparing
Inside Hirostar, the Alien Core is the other diamond you can defend with: Tolito Aguirre's mould with a softer 12K face and a medium-high balance, so a little more weight in the head than the Redstone IV. Alien Pro vs Alien Core covers that line. Outside it, the NOX AT10 Genius 18K Alum 2026 is Agustín Tapia's 18K teardrop, an all-court racket in stock now, and the adidas Metalbone CTRL 2026 is the control member of the Metalbone family, with a round head for the biggest sweet spot of the three. Compare puts any two side by side, and our Hirostar guide covers the whole range.

Frequently asked questions
Is there a Hirostar Redstone IV review yet?
Not an independent one that we have found as of October 2026; the racket has only just been announced. This guide sets out the manufacturer's specification and what each change should do, and we will add on-court notes when our stock arrives.
Is the Redstone IV the same as the Redstone 2026?
No. Rackets sold as "Redstone 2026" are the previous frame: Hirostar's 2025 mould with the Black EVA 17 core. The Redstone IV is the 2027 model, the fourth generation, with the Multi-EVA core and the NFC chip.
How much does the Redstone IV weigh?
Hirostar list 360–375g with a mid-low balance. Individual frames vary by around ±10g.
Is the Redstone IV a control racket?
It is a control-leaning diamond. The shape keeps an attacking sweet spot high on the face, while the mid-low balance and the softer feel of the Multi-EVA core favour placement, touch and fast hands over raw power. If you want a pure control racket, a round frame such as the Solar or the Metalbone CTRL goes further.
Is the Redstone IV good for tennis elbow?
It is the more arm-friendly of the two IV rackets: a low balance puts less load on the elbow than a head-heavy frame, and Hirostar say the bridge and Multi-EVA cut vibration. It is still a firm 18K diamond, so if you already have elbow trouble, a round, soft frame is the safer choice.
What is the difference between the Hirostar Redstone and Blackstone?
Balance. In the IV pair everything else is shared — shape, 18K face, Multi-EVA core and the 360–375g weight band — and the Redstone carries its weight in the hand for speed and precision, the Blackstone in the head for power. The previous pair split the same way.
Specifications from Hirostar's Pro IV catalogue and the Australian distributor's listing (ASPAC Padel Group), checked 10 October 2026.
