Internal parts just look as the vintage (2009) GR180 engine developped by Gerald Rutten.

Proof here: UT-160 turbine? Feedback please?

A bit dated and expensive design, btw.

So much contempt prior to investigation. I applaud the OP for keeping a good attitude.

The reason for build to order is so each turbine could be tested precisely and made sure that ever run as they should and customer doesnít end up with any issues, worst thing is getting a new turbine and having issues right from the get go because some little thing wasn't donít correctly and causes you headaches. Customer as of now will not experience any delays because of the built to order, will get it, maybe even quicker then some of the other brands out depending on where you are in the world. Reason for proper clunk is a get clunk is required to work properly, I have tested this with a normal brass clunk and then switching over to felt clunk, I did all the flips and roll and anything I could throw at it and had no flame outs with either but with the brass it would sputter a bit and I did not like that.

Seems to me that you have it backwards sir. Lots of investigation based upon OPís pics, statements, and even questions heís totally dodged. Meanwhile his positive statements are whatís largely unverified.

Red herring, much? Read the thread again please and be careful what you ask for sir.

IF one simply must rely on data NOT provided by the mf’r or the OP, then I refer you to the June/July RCJI test report.. If one simply must rely on data NOT provided by the mf’r or the OP, then I refer you to the June/July RCJI test report which has no more + than - commentary overall and ranks the subject 180 thrust:weight ratio of this “New” engine as 5th of 7 in the class, only beating engines from tests conducted between 9 and 10 years ago. Engines ranking 1-4 on the other hand are from as many as 12 years ago.

The RCJI report aside, the only “testing” required in order to reach negative conclusions regarding this product line are the OP’s OWN PICS AND COMMENTS, coupled with his deafening non-answers and/or side-steps to specific questions. And if one’s product must resort to claims of no need for a UAT as a “highlight” -a claim actually based on 15+ year-old felt clunk innovation rather than the engine itself- or to outright false claims of superior service intervals, then there are warning signs here regarding both the manufacturer and/or it’s representative. By these standards, one might as well claim Kero start as a “highlight”. The smoke being blown up our skirts here is glaringly obvious.

There’s little or no reason IMO (and apparently others’ as well) to purchase a poorly launched/represented engine from a new, untested manufacturer. All the more so when those engines, as per the manufacturer’s OWN SPECS AND PHOTOS (!) offer no new technologies or performance gains, are heavier, and cost more.

But hey, man. Free Country, so no judgement here on your own conclusions. If your rosier world view compels to spend YOUR OWN $ on these engines then please do. Meanwhile, you might do well to refrain from impugning others judgements of the matter.

Hey all, I visited this guy’s FB page. What I found were some pretty outlandish claims for this line of turbines as having better specs than ALL others, TWO SECOND acceleration time, etc. This, according to what one may infer from his photos and posts is a very young guy -one might even say a kid- with little or no real expertise. Maybe I’m 100% wrong, but I have tried and failed to find a reason to explore the brand with my $.

I wouldn’t go to the trouble of extending this absurd thread one post longer if he hadn’t been even more dodgy on FB than this forum (if that’s possible) when asked a simple question regarding performance.

I feel genuinely bad for this “Rep” (just not bad enough to hand over my $) because by all appearances, imo -and I truly hope I am wrong here- it seems like he is basically just some young dude in over his head who misjudged then audience here as unsophisticated and therefore vulnerable to weak marketing tactics.

Once again, I will say that I hope I am wrong…

Ok so I was reading most of the comments about the turbine, so this is my one first hand observation because I have chance to touch and look at the turbine and yes the turbine is bigger than those days 180 size turbines and look definitely different than what we see around but as a performance itís kind of like the big block engine with small turbocharged engines, it works perfect with very fast response and pushes the jet very well so the job is done, yes there some stuff that I would charge like the big all in one box that is much larger than for example the jet central power box and I will never advertise that the uat is not needed because as long as I fly jets this was a very helpful device no matter what turbine was used specially with multiple fuel tanks setup, so the turbine is maybe different but it works perfectly and only time will show if we the Rc jets enthusiasts going to accept and like the new product, just remember when the first Kingtech was announced what everyone was saying and tell that this is the next junk just like jetjoe from China but after the 2011 jet world masters everything started better for them and the beloved jetcat is not the first choice specially at this moment.thatís it and I wish Piter great success with this new brand.

Someone asked a question and I asked them to please refer to my more recent posts, nothing dodge about that just seems like laziness on your part because you could hav exist clicked on my name and seen more about the turbine. The two secound response was a spec on the engine but since has been bounced up to 3 sec. Nothing fishy thatís how it was.

Thank you Sysiek and I agree with you. This is a launch of a turbine, obviously itís going to have some stuff needing updating. Nothing is perfect and I appreciate all your guys comments so I can tell the manufacturer what they should work on to make it even better.

It's usually wise to do the updating before it's launched...

Other brands also update their turbines many times over the years after they have been released. Guess that isnít wise on their part either.

Sound like the old turbine that jeff Semore was selling in [ Neenah wis] when he was alive, he was making the first drone for Nasa. back in the late 80s.

Hey guys, so I did some investigating to see what the specs are for all the major turbines on the U.S market for the 210 size turbines(some brands have a bit larger or a bit smaller but more or less around the 210 mark) and I got to say the a-210 is a real competitor comparing to all the normal specs that the turbine mfrs have on there websites. Starting off with price, it is very competitive considering some brands are asking over $4000 for less powered turbines but we arenít here to judge. A-210 has the smallest diameter at 109mm followed by jc-200 at 111mm. It does have the longest length at 330mm but this includes the cone at the end not the actual can, again some brands donít have it even specified. Has the smallest amount of consumption rate at 450ml/min at 100k rpm, some companies, as you can see below donít, donít even mention at what rpm but alm meca has that specified. All around the 21kg mark since they are all around the 210n mark. Is the the second most heaviest followed by the p-200 but again some companies donít specify complete weight. On the high end has the highest rpm out of all the other engines at 124k, and has a 3.5sec acceleration from 33k-124k, again some of the companies donít have times specified(almost none actually) and has almost the lowest idle rpm at 33k, Jc-200 at 32k.





So to come to a conclusion, the A-210 is like I stated above very competitive in the 210n market. Also has some key specs specified even with other brands not having anything you guys have mentioned like 5000ft tests. Some brands donít even have some basic specs specified. Soon I will be making comparisons for the A-180. So all in all most of you guys made this turbine seem like itís an ancient artifact that doesnít have any specs but like I have proven has many key features that beat some of the other larger brands on the market. All of these came directly from the companies websites not making any of this stuff up.

Not going to jump in on this too much and I wish you guys luck but how is it competitive, its older tech? Its 180 thrust, weight and size of turbines that produce more thrust? If you run the numbers of fuel consumption at full RPM vs about 60% its going to be thirsty as well.
Im generally curious not being rude and base my comments on whats been shown about this product.

Here are the 180 comparisons for some of the most popular that are currently on the market and a lot of people run in the U.S. So again starting with price, very competitive priced at $2850 with most brands being around that price. But again some at almost $4000 which is a bit steep. With diameter it definitely isnít the smallest, but definitely not the largest, it places third in the line up k-180 being at the smallest at 103mm and largest being in-180 being at 113mm. Length is the largest at 330mm but tied exactly with p-180 at also 330mm. Has the smallest consumption at 370ml/min at 100k rpm by a long shot to the other brands; closest being sw-190 at 380ml/min at 103,5k rpm and p-180 being at 610ml/min. It is the heaviest at 2000g, k-180 being at 1540g but most donít say what that includes, Alm-meca includes that. Doesnít have the least idle rpm, x-180 does at 28k but does come in second tied with sw-190, and p-180, but again some brands donít state idle rpm but Alm-meca does. Doesnít have the highest max rpm, k-180 does have 130k but does come in second at 126k. Alm meca does 33-126k in 3.5 seconds which from what I can see is second in line behind jb-180 being at 3sec flat but again most donít include it, p-180 claims 1min which seems the highest but again others donít specify.



So again all these specs come from the mfrs websites and again the alm meca A-180 is very competitive and proves itís not a ancient relic like most of you portray it to be, but it could truly hold its own. Again alm meca has many specifics that most donít even specify. So for all you guys out there talking all this crap this just proves you guys have no idea what you are talking about and shows what this turbine can actually do.

Im generally curious not being rude and base my comments on whats been shown about this product.

Im sorry but I donít understand your comment, the 210 has the same thrust as all the others out there with the least fuel consumption at around the same rpm with some brands not even specifying what they consume! This is the case with both the A-210 size and also A-180. Both consume the smallest amount at the rpmís specified by other brands but again other brands donít even specify.

And Iím not sure what you mean by older tech? Seems like the Alm-meca run at or even better specifics then most of the ďNew generationĒ turbines out there. This includes the xicoy x-180 from what I could tell you are the dealer of?
