So recently I bought a cen matrix TR arena. I purchased it online, and was forced to wait over a week and a half for fuel. Now this is understandable, as it is not cens fault at all. So i was obviously a little anxious to run my truggy. So i start up my TR. 28 once i get fuel, and run about 10 or so minutes of the heat cycle method. Then of course my one way bearing breaks, i literally saw two needle bearings fall out of the bearing, and i looked with a microscope only to find out that the holes where the needle bearings should have been, were enlarged and there was no way of putting them back in without them falling back out again. I talk to cen they say that they dont have the one way bearing for sale and thatt I will need to wait a month to purchase one. Then the person I am speaking too puts me on hold, and then informs me that they will ship me one right away. They take down my address etc. and say that the part will be at my house with 6-8 days. So i wait, until the 7th day and then phone to check on the part. turns out they have no record of sending it, but informed to check my engine for metal shavings of an internal damage. I checked my engine and discovered that there was a peice of metal shaving rubbing slighly againt the con rod, I then talk to a neighbour experienced with motors and he tells me that my engine would likely seize within a hour or two of running, so i am now forced to send off the TR 28. to cen. cen simply told me to put it in a box so i followed their instructions and sent it off. Now i sent off the engine twelve days ago, on a friday, and cen received it last thursday. I phoned them on friday to confirm this and they said that the engine would be sent off as soon as they get the SH: 28 in stock which the customer service represenative said would be a couple of days. So here I am just off the phone with cen mad as hell, because I found out that it will likely be a week or so until they receive an SH 28 for me. And also, the one way bearing they said would be sent to me, I never received. So in total I have spent over 500 dollars on cen products, only to get a tank of run time through it. Now I understand that because I live in Canada shipping will take a little longer, but this is ubeleiveable on cens part. I can say that unless they give me something to make up for all this time they have failed to go by their word, I will never purchase a cen Product again. In total ive waited
7 days for a bearing that never came,
11 days for the engine
and then supposably another week for the engine to come in
and then another six days for them to ship the engine back.

Ive tried to deal with this as maturely as I can, but I am simply i disbeleif that they cannot find one SH 28 to ship to me. They should not have promised me a SH 28 in the first place if they will have to wait this long to get one in. Now cen could make it up to me by either shipping me an old TR 28 or Nx 26 now and I will glady pay the shipping on the engine, and then send me a Sh 28 when they get them in stock. I am not buying another cen product again, unless they give me some reason to beleive that they indeed care about their customer
For those who feel like calling me immature, feel free but I have told you my story truthfully.
