has anyone have tried both PRP and BMI chassis?
i'm looking into getting a set for carpet but not sure whether or not HPI to has their set released yet. which would be better?
any input would be helpful.
Thanks in advance!

awesome craftmanship and quality. best of all the battery slots are already filed down... I'm sure PRP is up to par with BMI.
contact Ray Huang..he's the expert on carpet with the BMI chassis.

racer: I have the BMI on my car, works fine on asphalt, bumpy track, not that i have tried the standard chassis yet to compare it to.. is nice and stiff though! Tower have the 2mm and 3mm chassis on their site now, so thy are out. PRP one looks very nice too
RC-Zombies: R10 = rainbow ten?
I have an order on the way from Tower, and in it is the associated spring and screw/bolt for the diff so i will give them a go, not that my diff has shown any sign of coming loose yet... maybe I will leave it as is and only swap them over if it starts getting loose.

no worries racer
I must get the standard chassis on to compare some time, wouldnt mind trying the 2mm as well
I bought my car wtih the 3mm already fitted up...
A wise investment also is 75144 Pivot block spacer set beacuse the thicker chassis plate will effect your roll centres because the pivot blocks will be .5mm higher than on the standard chassis when you use a 3mm. the pivot block set includes 1mm plates so you can use a 1mm and 1.5mm where you would have used a 2mm normally for instance. Or just a 1mm in place of a 2mm for a setup sheet that uses the 2mm chassis. This will keep your suspension geometry the same.

Good question
Have not measured it.. the standard top deck is 2mm, I think the BMI one is 3mm? It also comes with 3mm shock towers.

Please don't take this as a knock against BMI. From what I've read on here his stuff is very very nice, top quality machining. However, It looks as though the BMI Pro 4 chassis is a copy of the stock HPI chassis but with beveled edges.
Our chassis will be out very soon now, and while it does not have the edges pre beveled, there are quite a few options with it over the stock and BMI chassis kits. If I'm wrong about the BMI chassis, please let me know!
Thanks!

G'Day Ben hows it going mate?
Maybe you should raffle one of them off like BMI did, then I could do an A/B comparison of the two

Can you enlighten us on what the options are for your chassis?
Thanks, Mike

Has anybody out there run a serious top notch mod motor on an asphalt track yet? The reason why I ask is because I have only raced it in the stock class and I am looking to throw a 9 or 10 turn Orion V2 in it this weekend for a local asphalt trophy race and I was somewhat concerned with the cars durability.
Inputs are more than welcome...
Thanks, Mike

Guys I have seen chassis that BMI has made and they are of very great quality if you go with either chassis you will be getting a work of art. PRP does offer more options on the chassis....and going with either one you wont go wrong. Both are 3mm and once you build up a car with a chassis that thick its amazing how stiff it becomes....I think the PRP chassis would be a little stiffer as the top deck that comes with the HTS kit is full and has very few cut outs where the BMI ones that I have seen are cut out a little more so a little more flex.
