I really don't get Jinma Rides. They've been in the game for so long. The principles of making smooth and exciting coasters are hadly state secrets. They've had so much times to learn the ropes and find their own style.
And yet their style is invariably "some other manufacturer on a bad day". It's B&M, but with bad track profiling. Vekoma, but with uninspired layouts. Intamin, but hungover. I have yet to be made aware of any of their coasters that looks like their own distinct, and good, product. I know the term "knock-off" is taking it too far, as they do make their own designs and there are other manufacturers whose coasters resemble somebody else's to the same degree or more, but Jinma coasters usually end up reminding you of a sub-par, slightly "off" version of something you've seen before. And I don't really see any good reasons why it is like that.
As usual I'll play the roll of devils advocate for GH
No one else is going to do it.
I think their rate of improvement has been consistent and almost meteorically quick
I agree their rides so far are often Janky looking versions of western rides but go back just 10 years ago and they were pumping out only terrible clones of wild mice. Yeah the current rides arent much to shout about quite yet but they are way way better than they were and if they carry on they will get there sooner rather than later.
The first really very good GH coaster i rode was 2013s Expedition Volcano at HV Tianjin which is a lovely custom mine train and was the point i think they really started to improve. So that was only 9 years ago.
2016 (6 years ago) saw them take a big jump in ambition and saw them open Battle Of Jungle King the first GH Tilt coaster. Now i dont think anyones ever going to call it a good ride but by all accounts 2020's Broken Rail Coaster in Suzhou is a decent improvement with better suspension fitted trains and vest restraints giving a much better (if admitedly not B&M level ride experience) than the 2016 ride. And that happened in just 4 years.
The SLC's see a similar rate of improvement. 2007 saw their first addition of their first SLC at Fantawild, a Kumali clone that rides like crap. It admitedly took 10 years until they released their mk2 rides when Dragon opened at Long Gu Wan Dinosaur Park with their new track design. 2017 also saw the custom layout Happy Angel at Sunac Harbin open and saw their first step away from cloned western layouts for their inverted coasters.
Now they had their own much smoother track design it took Just 3 years before they worked on the missing link and added vest restraints and reworked suspension on their custom junior invert at Yinxian Resort which seems to have sorted out many of the issues with the older models. This is to the extent ive seen plenty of Chinese people comment they are now considerably better than the Vekoma originals like the SLC's at HV Beijing and Shenzhen.
----------------------------------------------
Taking a side step for a moment there is another issue at play here. We havent seen any more custom GH Inverts since then and I'd suggest thats not GH's fault. Big Chinese mega parks like Universal and Happy Valley go for western built rides because they have the money.
This leave GH supplying the mid and lower level parks. Now if you're a mid level park in China with a limited budget usually being built by a company more interested in real estate are you going to get a stock model invert like the Mk2 Kumali layout or shell out for a custom layout which probably costs millions more? GH are stuck in a bit of a hard place there, Their main customers will always go for the stock models because the big parks that can afford the custom stuff are going to go Western. its a difficult Niche to fill at the moment until they can prove they can compete. But they cant prove they can compete until they can built some proper custom rides.
----------------------------------------------
Going back to the actual coasters theres certainly misteps on the way so far. Their Dive Machines while custom look like poor mans versions of B&M rides and the same can be said about the new flyer in Xia'n however could they have built these just 9 years ago? Not a chance.
I actually think the LSM coasters they are starting to produce actually look rather good. The Blue LSM coaster in the previously posted video looks pretty solid. I mean the proof will be in the pudding but the rides currently being constructed at Silk Road in Hainan and so far it looks pretty damn good. The shaping looks solid and with their new trains I'm genuinly interested to see how this goes.
And hey if they ever get to build this thing it looks like something Mack or Intamin would produce. I dont know who they have designing layouts now but they dont look half bad.
I'm certainly not saying they are world beaters yet and maybe not for a while but theyve come one hell of a long way in the last 10 years or so. And hey how many years did it take Arrow to produce a genuinly non janky actually rerideable smooth multi looper in Tennessee Tornado? And even big companies have missteps.
Looking back Intamin built Z-Force in 1985 as their first big proper extreme coaster, They admitedly did much better with Shockwave (SFMM) the following year but it would be hard to say those stand ups were great rides and they certainly had loads of room for improvement. The much more refined Drayton Manor Shockwave was.... well 9 years later in 1994.
Are GH rides great? no certainly not at the moment. But I honestly think they could be soon.
TLDR:
Its a learning process building coasters, you need the experience, The manafacturing knowhow, the staff and the technology and that doesnt come overnight. You cant go from Crap Wild Mouse to B&M flyers overnight. 10 years down since they really kicked on and they arent doing too badly so far. 10 more years and ask the question again They'll either be great or I'll agree with you
. The next 10 years will really show what GH are made of.
