Please BE-WARE!
Just recently purchased the VMAR Engine Test Stand from Richmond RC for what looked to be a nice piece for the shop at $17.95 plus shipping. This test stand, quoted as "Accommodates 2 and 4 stroke engines from .09 or less to 1.80 cu. in. or more!" just isn’t true at all. To start off my test stand endeavor, I removed the semi-assembled pieces from the box to reveal a less than expected quality in craftsmanship (my over expectation, I’m sure). While assembling the structure, to the crude at best set of instructions, I noticed that many of the pre-drilled holes were off center from what was obviously designed at one time, etc. After assembling the stand and looking for dimensions for my Saito 1.80 4 stroke engine I found that the stand would indeed house, but just by a sliver at the maximum range of adjustment for the stand. Point #1: (the test stand it not large enough for anything bigger that 1.80 MAX and not even that, as I will describe in further detail). After “SECURELY” mounting it to a heavy table and rigging the fuel and throttle linkages, verifying the balance of my new Mejlik carbon-fiber prop, I started the engine and began to tune away. After running it at high throttle setting for less than 3 minutes my brother also standing behind the engine (thank GOD) noticed in a matter of 500ms that the engine was coming loose of the stand. After we both ducked and headed away (maybe 2 seconds total) it was all over. The engine was in the lawn and the prop was in pieces, along with half of the aircraft supporting holders on my brothers flight box that was on the ground in front of the occurrence. The two laminated wood adjustable engine supports that were ADEQUATELY sandwiched together as engineered, separated, and that was the point of failure. Needless to say, and with pictures to prove, (will be posted along with this thread in a couple of days all over RcUniverse) Point #2: I will contact Richmond RC and let them know that I will accept the REPLACEMENT cost for the (Engine Test Stand $27.50, the Mejlik 17x10 prop $40.00, and a new flight box $48.00, Dirty underwear (no charge)) to be made to myself within a timely manner or I will bring suit against them. Money is not an object and is never more important that principle in these types of situations. They have misrepresented a product that is insufficiently engineered for their specifications of engine allowances. I am glad that I have not bought any other VMAR product nor will I ever !!!!

I must disagree. I bought this stand a year ago and have broken in about 7-8 motors on it from 46 size to saito 150 size. The smaller engines I just hold the thing to a platform with clamps, The larger ones I screw in. For the money It has been great. Of course you allways need to be aware of screws coming loose due to vibration etc and you may have to add a bolt here or there but for 18 bucks it has served me very well. Personally I wouldnt put anything bigger than a 150 on it though. I also ran wood screws thru the bottoms of the wood engine supports for extra strength.

Dolby I had the same thing happen to me as I was breaking in my Saito 100. One of the wood blocks holding the engine mount seperated as I was running the engine. It loooked like there were just two dowels holding the top and bottom of the block together. Luckily I was able to shut the engine down but it was scary watching the engine tilt to one side held up by only one side of the stand.

Dolby is my bro, I was there....and let me tell ya...I definitly needed to change my shorts after that one. Its exactly as you say...the wood mounts for the engine came apart at the "lamination point" where the 2 dowels were...on BOTH sides at the SAME TIME. The engine just "Walked" upwards when me and my bro dove backwards just as the engine flew off the mount (wood blocks still attached to the motor mount) and corkscrewed 25 feet out into my lawn...cutting the top off my flight box. Scary

I for one will NEVER purchase anything from VMAR. So much for the first link that pops up on google when ya type in "RC Engine Test Stand"!!!!!

Glad that no one got hurt with the incident! I almost had to change my underwear just reading your account!

I realize this is a little late, but if your still in the need of a really quality test stand, I would highly recommend you try the folks at PSP Inc.! Their test stand is more expensive, but I can't imagine ever having any problem with their equipment. I have one and I
guarantee you will like it. I also have a friend that has run his ZDZ 80 on his stand with the attachment for the bigger gas engines. Very nice folks too!

Take a look: http://www.pspmfg.com/

Comparing a 80 dollar stand to an 18 dollar stand isnt really fair. I will agree VMAR should probably change the wording and limit there stands to 120 size engines for safety sake. You can just look at it and know it's not strong enough for a 180. But once again for breaking in smaller engines I have found it to be worth the money

Sorry about your problems with the test stand - I also purchased something from them and although its not even close to your situation I noticed in your article you related that you had "contacted' them. How did you do this? There isn't any E-mail address or phone nbr on their website. I ordered a Balsa stripper from them for my Grand-son three weeks ago and haven't heard anything from them. I would appreciate any info you have --Thank you Mike Burnett e-mail [email]amissville@outdrs.net[/email]

It is time to resurect this thread! After a recent positive review of the Vmar test stand, a friend of mine purchased the item. The holes did not align, the wood blocks were different thicknesses and the L brackets did not even measure 90 degrees. The spacing between the L brackets is far to wide to even contact the wood blocks, which is a must for a solid mount. It is literally impossible to put this stand together without a total rework. The stand is on my workbench, and I would not trust it with anything over an .049, if you could get it together. It is terrible! I can't believe there have not been serious injuries from this product. It should be removed from the market imediately! Anyone that has had a positive response from this product got lucky! It is obvious that the inconsistent quality from Vmar continues!
