Default DB02 cheaper alternative to TRF502 announced tamiya 58507

Tamiya release schedule:
58507- RCC Middle Class Shaft Buggy DB02.

Might help get some cheap spares, also looks like they are moving away from belt off road buggies

I had exactly the same thought when I saw this: The excitement about the fact that Tamiya will release a new buggy, but the disappointment that this is probably the end of the line for Tamiya's belt driven buggies.

no pics yet, the info is from a shop stock release list (along with a load of tt01's and a VW camper van on a lunchbox chassis)

I hope it comes with gear diffs instead of ball diffs. I'm tired of rebuilding the diffs in my 502X.

I talked to someone at Tamiya America and he said there were no plans to discontinue DB01.

There you go! Seems like this car will have a centre diff? I hope it will be one that can be filled with oil then! I see a slipper clutch in the design as well, so there are hopes Tamiya will finally release a club racer/high end basher with a slipper clutch!?

I do think they need to re-consider that body - hideous! The wing seems to be the TRF501X/DF03 MS one.

From Tamiyablog...



Very wide shell. Why?



Because it seems to be concealing a transverse motor with a complicated central gearbox. Superficially it looks like a centre diff, but I think it is actually a dual-gear drive, one for the front gearbox, the other for the rear.

Interesting solution, rather like one of the possible ways of building the Awesomatix touring car, and evocative of the classic Tamiya 4wd chassis. Puts the motor in the ideal orientation for getting the power down, but also hangs it out off the side of the chassis.[/URL]

it looks as if it will have two counter-rotating propshafts. I wonder if tamiya have done some computational modelling on this design - looks quite a complex thing to try at random.

I thought that at first, but if you look a the relative position of the bearings for the output shafts, they are offset, so the two pairs of gears are not meshing together.

Appears to have enough space to take a third saddle pack under the rear drive shaft
What would make this really awesome is if they had designed the body shell to emulate the manta ray!!

They seem like the small LiFe batteries they're trying to use in all of their new releases - or it's a stick pack with two braces over the top of it, making it look like 3 batteries I just hope they make it compatible with regular size batteries as well or this chassis won't sell.

Anyway, I hadn't spotted the offset on the gears yet. I don't see though why they didn't use a single shaft and two gears less instead then if it's not a diff, this just results in more mass, and in the exact spot where you don't want it: Your drivetrain. It also doesn't seem to result in any advantages for moving the motor more to the center.

The best things from the 502X and the 511 combined in one car.

The position of the electronics and the steering geometry from the 511. The gearboxes from the 502X.

Slipper is not included but optional:
54336 DB02 Slipper Clutch set

ah yes - you're bob on. the offset is maybe 3mm & there's a solid layshaft to the opposing pinion. wouldn't it be cool if tamiya took this opportunity to introduce some sort of torque splitting device on the layshaft?

I love it, Tamiya madness! So does that mean the rear propshaft is high up in order to clear the battery? Can't quite make it out?

Like someone mentioned, question then will be if Lipo's will fit, either a saddle either side or a stick underneath?
