My Race Revo

[rchippie]

Dafni your DVO 2 (as i call it looks great) .

My first post here - I've been looking to start another project, decided to do a BL conversion on a Revo, and found this place. I do alot of custom machine work on my own projects, but I must say Dafni, I'm impressed with your machine work. Very clean and simple.

A vew questions: I don't know much about center diffs vs. shifting trannys - the Ofna diff you show; does it use a slipper clutch of any sort? Is this just a direct drive (no gearing reduction)? If so, I assume all the gearing is accomplished with varying spur/pinions?

I was going to go the e-maxx tranny route, but definately like the looks of the center diff instead!

Thank you Hippie!

And thank you too, Cadtech. And welcome to the forum, nice to have you here.
Well, those 1/8 buggy diffs have no slipper, unfortunately. The lack of a slipper is a downside, but I hope it just works. Some other people have used this kind of diff setup without problems.
You are right, this is a direct drive setup. The front/rear diffs offer some reduction, of course, as well as the center diff with its big spur. The pinion on the motor is the only place that let's you change gearing reasonably.
With a center diff truck, compared to a tranny, you need to select a different motor. Just calculate your overall reduction and choose a motor that gives you the desired speed at your particular voltage.

I guess you have seen my first Revo with the E tranny. This was done over one year ago, and I have learned alot about BL and RC since then.

Cadtech, how about showing some of your work? I always enjoy to see custom RC stuff.

Cheers

Thanks for the welcome, and the primer on diffs.

Lack of a slipper is a concern - but hopefully the diff-action from the center and ends would save the driveline. Although I imagine the Revo driveline is fairly bulletproof anyway (suppose axles are about the weakest link, eh?).

Without hijaacking you post with my pics, I'll point you to my webshots page:
GP-Maxx - a gasoline powered Maxx:

This album shows some of my other things (bl rusty, stampede, etc.); also have a bl Losi XXX4 (machined custom cf towers for that) as well as large scale gasoline powered boats I machine alot of parts for that aren't shown.

You're welcome. And don't worry about hijacking, I myself are a wanted hijacker, gotta hide out in the woods. I guess they had put a reward on my head.

Thanks for sharing your pictures. I can see a BL revo would fit right in.

Yeah, the slipper is a concern, indeed. But, as you said, the center diff will be a bit of an insurance, and I think I have a well controlled throttle finger.
The weak link, for acute impacts, will be the rear diff I suppose. And for wear over time, the weak part might be the yokes. Just my opinion, only time will tell.

Have you put together any more of this beuty? If so, please do show :) :004: :004:

[Dafni]

Working on it as we speak :) Just put the file down to type this.
It will soon be finished, and I make sure to post some pics.

If only those days could have a few extra hours....gotta go to bed soon, but I hope I can get some work done over the weekend.

Thank you for your interest, Sylvester.

Good to hear:) If you dont mind me asking, what shock setup are you running? (spring/oil combination). What do think or want the weight of this G3R to be?

[Dafni]

No, I don't mind you asking, not at all. But I really can't say much about the weight yet. I expect it to be low, it will be my first Lipo truck. The motor is heavy, though. 360g for a 1950. Let's see. I'll give you the exact number when I'm done.

As for shocks, well, I have more than a year experience on my first BL Revo, and I would guess on the G3R 50 or 60wt oil and stock pistons would be fine. The springs on this one will only be one step apart I figure (weight bias will be different as on a stock chassis). I guess something like tan front and gold rear, or one step more or less depending on track.
BTW, on my first Revo I run the LT rockers, and I love it for "brawling" (bash-crawling :) )

sounds good DAF cant wait to see the updated pics

[coolhandcountry]

Yeah dafni has some good ideas in that head of his. If I could just get over there to get some of them. :D Oh well. I have to stay here and read about them i guess.

hey if dafni comes over to the get-together you can get them then chc

Amazing project, Please keep us updated
