Couldn’t resist.
The RFM M50 Mk2 seems very nice.
I’m afraid
to read any reviews on it after Opus 4.7 pulled information on the RFM JS-2 #5160 kit. I wanted one regardless etc.
Anyway, here’s a summary of what Opus 4.7 reported…YMMV
RFM RM-5160 IS-2 Mod. 1944 — the short version
Expecting a clear step past the old Tamiya kit.
It is not that.
Pulling the main points together for anyone still deciding, drawn largely from Holger’s teardown at tigerscorner and the Scalemates thread.
The core problem: RFM copied the 2005 Tamiya kit’s geometry and improved it in two places while regressing in several others. Turrets, mantlet trough, mantlet jacket, and gun cradle are effectively Tamiya twins. The RFM muzzle brake even drops onto a Tamiya barrel because the seating is copied to size.
What they fixed vs Tamiya (the entire list):
- Driver’s periscope spacing on the front roof — now correct
- Commander’s cupola viewing slits — now correct
Both real, both small.
What’s wrong:
- Running gear is the worst area. Cast wheels crude, tread surface oversized. Balancer brackets hopelessly overscale. Bumper nut molded plain instead of castellated, flanking ribs too thick. Balancer arms lack the weld bead though the groove for it is tooled in.
- Ammo loading hatch wrong thickness, hinge laid on top instead of seated in a machined cutout.
- Lifting rings molded integral to the hull on a 2026 tooling.
- Coaming-box-to-rear-hull bolt pattern misplaced. No Plant 200 casting number on the left coaming wall. Drain holes scribed, not pierced.
- Marker lights wrong. Gun travel lock is the post-war pattern. Driver viewport housing oversized.
- Weld beads and cast texture token at best, no Plant 200 character.
- Cupola insufficiently oval (copied from Tamiya) and undersized — should be 27mm minimum at scale, real ones run closer to 28.5.
- The anachronism that breaks every build out of box: late oval-slot rear hinges (Dec '44) combined with a radius-cut turret roof rear edge (discontinued late Nov '44). These never coexisted. Pick one to correct.
- Workable plastic tracks are clunky — worse than Tamiya’s older semi-workable links. The announced 3D upgrade set looks crude in the render.
- PE intake screens are diamond chain-link. Wartime IS tanks used woven cloth mesh (1.4mm wire, #49 type S-1). Holger’s strongest call-out because the error keeps getting repeated by reviewers.
Decals: the “БоЯвая подруга” typo (should be Боевая) is decade-stale — it traces back to Zaloga’s 1980s Osprey plates and the 90s Dragon kit. Worse, none of the marking options can be built accurately from the box; every one needs a turret, cupola, or hull variant the kit doesn’t supply, and the Polish “Berlin” attribution is wrong.
Plus side: molding quality and fit are excellent, separate fenders are well thought out, the 3D muzzle brake is sharp, clear parts and a usable copper tow cable included. The PE frames work as a substrate if you back them with fine nylon filter mesh (60–70).
Holger’s verdict is “mediocre,” and his recommendation is to wait — Zvezda has a cast-nose IS-2 confirmed, and they’ve already corrected the balancer ends and crown nuts on the shared suspension sprue mid-run.
Bottom line: if you want a buildable IS-2 today, Tamiya plus an Aber barrel and EVM cupola is still the safer path, and several here (the other forum per Opus) cancelled RFM pre-orders on exactly that logic. Zvezda Lobnya is the most accurate out-of-box option currently. The RFM kit is for builders who specifically want workable tracks and great fit and accept reworking the running gear, cupola, loading hatch, the hinge/roof anachronism, the PE mesh, and the markings.

YMMV - RFM is my favorite kit manufacturer. I think it will build nice based past RFM build experiences but I shouldn’t have bought more than one copy of this one.
