DCM, why would it need a crease? its 3mm alloy.
I don't know what all the debate is about, none of you guys are the designers. Have faith, that whatever any brand does, its been extensively tested and its like that as a result of the test, so don't slate it before its even hit a track! Some of you guys set a cars reputation before its even gone any further than pictures.. and others listen.. FFS stop it.

[quote=Lee;91931]Yup, if this car has the precision of the b4 and the stability of a losi then it will be the best car out there, quote]
What an excelent description of the RB5 .... but you seem to have posted it in the wrong thread!!!

It is great to see something a little different out there.
I am not sure what the hell people are on about with the looks of it ..... who the hell cares what it looks like naked .... when it's being raced it will be fully dressed so before we say ugly lets wait till we see it in it's party dress. I think Adam should be congratulated for not doing another clone which seems to be all to common these days. If it's not a decent car I'd be very suprised and I say the more choice the better as not everybody likes the same driving feel. This car will suit some people far better than most other cars, other people will think it drives like a shed .... that's just life! I like the car for the fact it has obviously had some serious engineering thought applied and the fact that surfaces like grass and astroturf will ahve been considered at the design stage not as an after thought. Looking forward to seeing one go on a decent off-road track. Am I going to be putting my RB5 up for sale, no ..... not a chance. Am I going to slate a car that has not had a chance to show what it can or can not do, no.

  Can't this be put in the hot bodies thread? As I keep going to the wrong one.  ....I say, lets wait until Adam bring one to a track and kicks all our arses before people slate it!! And who says ugly can't be beautiful? Hasn't everyone been looking for something different for the last few years? and now its here, everyone hates it!?

There are some things i like, and some things i don't like the look of - but it's always hard to tell from pictures. Don't think you can say a bare chassis looks ugly, need to wait for a shell to say that really.
I have a sneaky suspicion that the B4 geometry is nestling in there somewhere as well but let's be honest, on the whole for most people it works, so why not.The thing i find very interesting is the choice of assembly/materials. Although there is a definite up turn in 1/10 off rd, there still seems to be a bit of a resistance (and oddly from the bigger companies) to invest in mould tooling. Aero and X-fact are relatively small companies compared to the might of Tamiya and HPI and so you'd maybe expect their choice's to be the direct opposite to what they have been. It's all good though.

So I guess it all comes down to material choice and post forming/stamping process that will dictate it's overall strength and rigidity. It is like Carbon fiber, there is CF and then there is GOOD CF. Also, if you lay p the good CF and use an autoclave to cure it, is makes it better again.

TEAM LOSI RACING RULES!
I think it will be a contender in the buggy classes!
 I also think it is a good looking car might have to switch from losi to Hot Bodies? And i own a B4 and have'nt even gave it a try yet!

I'm quite surprised how many people are trying to slate this car?
I really like the fact that there is a new car on the market. Its great for 10th off-road. Its even better to see an unconventional car being developed too.

I doubt it to, but even the stiffest material could be helped by a crease, take a tip from the Nitro chassis makers....

Very interesting. The front shock tower brace is cool. It's nice to see more players in 2WD off-road.

To my mind this is a bad thing as it removes the ability of a driver to choose what suits him best. Think back a few years and the Losi XXX and the B3 where classic examples .... totally opposed dynamically and you'd find some people would prefer the B3 (I was one) and other prefered the XXX, it was all down to their personal preferences. The 2wd's today are much less different in handling terms, although there is still some spread and thus some people like the B4, other the Losi and others the RB5 which sits in the middle. The situation is much more of an issue with the 4wds which all seem to have fairly similar geometry and weight distribution straight from the manufactures, with the exception of the ZX5-SP which is why that is my choice, it suits where the others don't (having said that Gaz Stanton's Yok BX seemed good when I drove it). All I was trying to say is that choice is never a bad thing!!!!!! The HB D2 (or whatever it will actually be called) looks like it should be an option well worth considering, just have to see how it goes on the track ...... well in the right hands I'm guessing.

I must say as a design engineer I have to agree with DCM.
Since they are probably stamping the chassis plate to form the kick-up and cell cut outs I am suprised to see there is no raised material anywhere to give it longditudinal stiffness as well as improved torsional stiffness. It might be the case that the edges of the chassis are slightly bevelled upwards where the side guards attach but we can't see it in the pictures, that is what I'd do as you don't need a dirty great step ... any upturn would be of benefit.

Roger,
I'm a design engineer too (if you check my city, you know at which firm oooo ...), probably the 3mm thickness alone gives an huge amount of stiffness. If you chose a material which allows to bend the edges in the manufacturing process without producing small cracks it has to be softer. I guess they went to a highly alloyed aluminium, very hard but allows no small bending radiuses (sp?). the 3mm thickness together with a higher E-modul gives the strength

Micha, I know what your saying ...... I am assuming that the kick-up is stamped in .. which would suggest a certain range of materials (or a certain other range with some post forming heat treatment) which would make it possible ...... although as you say not down to a very small radius. I was actually thinking something like a 30 - 50mm radius (internal) and only lifting the top surface by 3mm or so above the main surface using that bend radius. You wouldn't want too much of an angle or else people would complain about not having a flat enough surface to mount their electrics off.
Just thinging out loud an making the assumption that the material chossen would be simialr to that used in the HB nitro cars. Does it need to be stiffer ..... very difficult to tell from a picture .. LOL
