I find it Hard to believe but i think the exb 8s chassi at least the first batch are made of poop Aluminium. How easily it bended vs the m2c with an hammer. The m2c didnt even flex. The exb one just bended in camera like it was nothing.

I know it's stamped junk for sure & it can bent like any other stock chassis. As per the vid, I found a local company that will cut me a fresh 1/4" bar 3.25" x 19" of 7075-T651 that I will slap to the chassis. It was $35 shipped. I can buy 3 of them for the cost a one finished "bash bar".I find it Hard to believe but i think the exb 8s chassi at least the first batch are made of poop Aluminium.

I'm about to switch over my O8S to a M2C crusher. I He-Manned the crusher over my leg & it did give a bit - very slightly, still bone straight afterwards. I did the same to the stock O8S chassis & it has permanent bow in it right in the center. The ribs did make it hard but it definitely couldn't handle all my weight like the crusher did - less than half before I felt it bending. Since the EXB is flat without any supports, I could probably bend it with very little effort at all. BTW, when I tried to bend the 1/4" bash bar wannabe, all I got was some pretty red marks on my handsI can bend mine with my hands. No hammers needed. And I was a sucker who bought the bash bar. Should have just got the M2C aka REAL 7075 chassis.
Are you referring to the radical rc UK bash bar? I really hope not because as of a few hours ago I have one shipping to me for my K6S EXB......I can bend mine with my hands. No hammers needed. And I was a sucker who bought the bash bar. Should have just got the M2C aka REAL 7075 chassis.
this ^^^for sure.How do the bend creases look? Is the surface around the bend smooth, or does it have micro fissures around it? If it is smooth, then no question, they forgot the T6 part (heat treatment!). If it has fine cracks, then it is indeed T6 and the 3mm thickness is not up to the task. 7075 is a bit stiffer than 6061, but it's not steel... Everything has its limits (unless you run a limitless). Maybe Kevin Talbot is right about it being too thin.
Yes that’s the one I bought. At the time M2C didn’t have a V5/EXB chassis yet. I should have just waited.Are you referring to the radical rc UK bash bar? I really hope not because as of a few hours ago I have one shipping to me for my K6S EXB......
Crap....oh well. too late now. Is it good quality atleast? I'm not a 100' jump type of basherYes that’s the one I bought. At the time M2C didn’t have a V5/EXB chassis yet. I should have just waited.
Yes it will for sure hold up. It’s just almost 75% of the cost of the M2C chassis. It is a thiccc boiCrap....oh well. too late now. Is it good quality atleast? I'm not a 100' jump type of basher
Yes it did seem a little pricey for what it is but oh well. Thanks so much for reassuring me that I didn't waste my money haha.Yes it will for sure hold up. It’s just almost 75% of the cost of the M2C chassis. It is a thiccc boi

The bends are by far the hardest thing. True 7075 doesn't like to bend. Front kick up can be done well in a garage type shop but the length wise bends to stiffen up the center section need serious tonnage. At least I haven't come up with a good way.A piece of 4mm 7075 sheet for a 6s chassis is about $30 at rip-off retail mail order prices. The chassis is a profile outline, a few holes and countersinks, and a wee little slot or two. The wings and rocker can be face milled or bent in a press brake... I haven't paid enough attention to the nuances, but either way it can be done in the home shop. I have a big mill, and there are a lot of other people out there with mills in their garages, university shops, work places, whatever... If I toast my chassis, I think I'm going to give knocking one off a shot.
