Enough Rear and Mid motored buggies!

Regardless, the project looks fantastic and once you have it all completely finished perhaps you might be able to sell a conversion kit?

I have an RB5 and the Durga parts are easy enough to get so I'd love to drive one

I guess this buggy meets local rules as far as width is concerned. But that said, I'll take a look later... I have some ideas that should be easy enough to execute to shave off that 5mm or so from the width.

Would love to se a action video of this car on a track

[BloodClod]

Re-cut the white delrin parts in black instead!





Hopefully a video to post soon!

[SHY]

Wow! Übercool!

I'd love to try one!

Name suggestion: "The FrontRunner"

[BloodClod]

Frontrunner is quite interesting!

Everyone's asking for a video so here you go!

In the vid the buggy is being driven by different drivers having a go at it.



Not too shabby?






In case youtube is giving errors playing here, you can view it direct on youtube here.

[MHeadling]

I'm well impressed with how it goes!

Good work dude!

[JensK]

Not shabby at all.. .I`m super impressed..
Thought it would nose-dive more on jumps, but obviously this isnt the case at all.. I`m in love with the concept and have to make me one for myself..

Looks like it gets around marvelously.

[OldTimer]

Looks pretty good, and the black parts look a lot better

I think i have found a project for the winter lol.

[ojoloco]

Nice video! It looks really good on the track, i can see this car starting a "fwd fever" here to forget about "mid" conversions

[samd]

Good work!

Thanks guys, the weather's been decent the last two days so the car's done a few batts worth of laps on the track and been run by different guys. So far everyone thinks it's a blast to drive. The consensus at the track has always been "4WD is easier to start with than 2WD" but the guys who've tried the FF buggy think this is the easiest buggy to drive yet. One racer commented that even a 4WD will spin out on certain surfaces because the rear wheels are still "pushing" the car, but for a FF this doesn't happen.

So far the car has been the easiest to drive consistently around the track in a variety of conditions and I think that's it's huge advantage. Since there's no worry about the rear breaking loose, one just needs to concentrate on getting the line right to carry the most speed through the turns.

One other pleasant surprise is... the car cleared the triples today a couple of times! I initially thought that the wheelspin was causing problems for the car getting up to speed for the triples but now I'm pretty sure it just needs a bit more motor. It's currently running with a 10.5T but I'm going to try a 8.5T to see how it goes.

Hiya folks,

I've just had the opportunity to drive the v2 version of bloodclod's creation....

The truth is, it drives so incredibly well, it's insane.

The traction today is loose and extremely rough. I was expecting the car to slide but it never did.

If anyone has driven a tamiya fwd mini on a high grip surface... it drives just like it...
Point where you want and peg it! Coast just before the turn to transfer weight forward and peg it immediately after to negotiate the turn.

What's there not to like?

Taking orders here!

I hear it weighs in at only 1400 grams.

Hi,

Congrat to your nice creation...

I love FF cars,,, in my very early days I drived a FF tamiya,, was always fun.

The ability of your car is impressive!!!!!!!!!!

GUYS!!! Time to think about something new

Hope youll kick some medals on the events

[j.m.]

Using a standard production rear suspension arm would be nice to see if you could come up with an appropriate rear hub system that allows you to adjust toe. Like the turnbuckle system on a predator or the other homebuilt pictured.

Camber would still be hard to adjust with this system, but it could possibly be done with shims under the arm mounts on the chassis.

Not sure if you caught this, but the HPI_Kogaff has a saddlepack configuration. The chassis also is much lower compared to the other cars because the rear arm mounts are so elevated from the lower deck.

How did you get enough clearance on the front steering to use the wider rear rims/tires?

Cool car!

ive always wanted to make a fwd buggy but looks like the yokomo yrf2 sp touring car but never knew haw well it would really go but after seeing in the video haw well a front wheel drive buggy can go i might have 2 give it ago

Thanks guys - this project has been a lot of fun!

Please do build your own FF buggies and post them up - I guarantee you the drive will more than justify your time put in!

Thanks! I did think of a production arm but I really wanted to use the trailing arm for this project just to see how it would run. I think because of the unique characteristics of a FF buggy, a trailing arm would work better to retain traction and handle bumps. If nothing else, the runs so far suggest that a forward weight bias is key to forward traction on this car... and the very long trailing arms certainly ensure the rest of the weight is put far forward in the buggy.

Using the standard steering parts from the DB01/501 don't pose any clearance problems with the wider tires, the problem was more track width which had to be narrowed by moving the inner hingepin mounting positions closer to the center of the chassis.

[j.m.]

I'm saying use a standard arm FOR the trailing suspension setup, like the previously pictured homebrew.

I know the steering setup would be rediculously hard, but a mid-motor front wheel drive car would be awesome.

Looks great!

AFAIK front wheel drive is not legel according to EFRA rules though

But should be BIG FUN for club racing though!

How do you cut those delrin parts? CNC machine?
