Otis311 196 Posted March 28, 2019 I'm reading it as the motor mounted in front of the rear axle. Should help fit more bodies. Share this post Link to post Share on other sites
geniusanthony 361 Posted April 4, 2019 Looks like a proper chassis for those MX5 and Fiat 1000 TCR bodies. From https://tamiyablog.com/category/future-releases/ 6 1 Share this post Link to post Share on other sites
Superluminal 3750 Posted April 4, 2019 It actually does! The other m chassis always looked like a collection of cobbled together bits to me whereas that looks like a proper chassis Share this post Link to post Share on other sites
geniusanthony 361 Posted April 4, 2019 I like the stabilizer bars on the rear body posts, should help keep hatchbacks from getting all wobbly. Oh, almost forgot about the R5 Turbo 2, Alpine 110 and countless others which were on the "wrong chassis". My mind just went to a twin motor M with M07 front and M08 rear gearboxes... then I stopped. 1 Share this post Link to post Share on other sites

TwistedxSlayer 1290 Posted April 4, 2019 I'd love to see that in a none M sized chassis. Proper touring car sized so I could have a real mid powered RWD Ferrari. Share this post Link to post Share on other sites
TurnipJF 9192 Posted April 4, 2019 Not as overt an exoskeleton as I was anticipating, but it still looks like part of the family as it were. I wonder how many hop-ups it will be able to share with the M-07? Share this post Link to post Share on other sites

Couldn't someone enterprising design a longer spacer to get 257mm wheelbase for 3D printing. There was that fantastic M04RR XL conversion in the builds a whole ago that used tl01 suspension and a 3d printed bracket to make a rear motor RWD touring car.

It’s definitely more of a tub chassis where as the M07 / TA07 do not have the raised tub edges, instead have stiffeners on the outer edge of chassis. On this, the chassis stiffener runs down the centre is chassis All of the suspensions hops ups of M07 work.. eg up rights, suspension mounts that set rear toe etc 1 1 Share this post Link to post Share on other sites

Always wanted the Alpine too and this chassis is perfect for it. I think I’ll have to get one of these. 1 Share this post Link to post Share on other sites

Also, do you reckon that it follows the M-07 in using longer touring car shocks, or the rest of the M-chassis range in using shorter ones? If the former, I hope that the low profile shock towers from the M-07 will fit it, or that low profile shock towers will be available soon, as I don't see any reason to use longer shocks when shorter ones will work just as well while providing a lower centre of gravity along with compatibility with my existing set of M-chassis springs.

ThunderDragonCy 7881 Posted April 5, 2019 12 minutes ago, TurnipJF said: Interesting? How does the gearbox layout affect traction? On RWD mid motor cars a 2 or 4 gear layout spins the motor the same way as the driven axle so the torque reaction squats the rear of the car 'pressing' the rear wheels into the floor. A 3 gear spins the motor the opposite way so the torque reaction acts in the opposite direction, tending to load the fronts. A track grip levels have increased in buggy racing this is why the 3 gear mid (so called 'Laydown' and 'Layback' drivetrains) have gained prevalence, as you're rarely traction limited at the rear on a buggy due to the size of the rear tyres and the grip available on astro or carpet, but understeer is an issue, so the motor driving torque forwards loading the fronts on throttle is beneficial. 4 1 Share this post Link to post Share on other sites

Ah, that makes sense. With my M-chassis cars I am usually trying to shift the grip bias towards the rear so this should be a good thing. Share this post Link to post Share on other sites

Has the added bonus of being easier to handle than 3 gear in my experience. The on throttle offloading of the rear wheels on a 3 gear makes them quick spiky to handle on corner exit in lower grip conditions, whereas 2 and 4 gears or rear motor 3 gears (which have the same effect because the motor is behind the axle) just plant their rear tyres and go on the throttle. As I said to a friend about wrestling with my 3 gear laydown over the summer "it's a *******, but it's a fast *******!" Looks like a super compact transmission but still uses the TA06 diff (as do the later 2wd TRF buggies) so could be some scope for adapting it to buggy use too. 1 Share this post Link to post Share on other sites

TurnipJF 9192 Posted April 5, 2019 Unit 21 in Sleaford has a regular Mini class, but they are on a temporary hiatus due to having lost their venue. Hopefully they will reopen soon at a new venue and racing can continue. 1 Share this post Link to post Share on other sites

Thanks for that, good to know (and so well explained). I will have a chat to some of the other RB6.6 drivers tomorrow (weather permitting) so see if they have tried the 4 gear transmission. I never have but its is probably worth it based on your explanation. Umm, in the M08 that I will be sure to get later when its around, or something, rather than highjack the thread...

Raman36 1656 Posted April 11, 2019 Preorder is up at tower. $198.49.. $1.50 away from $30 coupon lol. I added a $2.99 tube of grease to get there haha. $170 is not bad with the stupid MAP they implemented. Stella and RCMart with shipping may still come in lower.. will hold off for on pressing buy for now. Share this post Link to post Share on other sites
