Just a bit of an update, I received the Dirt Hawgs on Friday and glued them up Friday night. First observation is that they are big and look a bit goofy, second observation is that the insert if soft leading to a pretty squishy tire.

Saturday morning I ran them in front of the house and proceeded to traction roll twice, I dropped the rear ride height a bit and that seemed to help. I also found them to not be very progressive on asphalt and if you tried to get into the power to early the B5M would lift the inside rear wheel and "diff out". I think this is because the tire/insert is so soft and the tire folds over under load. When I do "diff out" the tires balloon like crazy, kind of wishing I had put a layer of tape inside them. I played with the diff a bit and went a bit tighter then I had had it and that helped a small amount.

Yesterday I ran down at the beach and the outcome was much better. The parking lot is packed crushed rock and dirt. The Dirt Hawgs were hooking up pretty well and in straight line acceleration were lifting the front wheels when hitting a bump or undulation. I also had times where I was able to hold a pretty decent drift and they felt progressive. On the packed sand of the beach itself they did OK and the suspension got a workout running with all the undulations, it was actually super fun and really showed how much better the suspension is on the B5 compared to the old RC10, the B5 was just so much more composed on the bumps.

The last thing I can comment on is wear. I ran 6 packs through the B5M this weekend and the tires barely show any wear at all where as with the previous tires they would have been bald by this point.

In closing the Dirt Hawgs do not handle nearly as well as a true race tire But I think some gains could be made with a firmer insert and maybe a layer of tape to keep the extreme ballooning at bay. With that said for my purposes they work and I will not go broke keeping tires on it. Once these are done I will try another pair and see if firmer inserts help at all.

Cheers,
Jim

If you are on a typical 10th scale track, leave them off for maximum steering. If you run oval, on large 8th scale tracks, or don't have any tight turns you might want to install them.
Ok, now I get it.

Default B5m Fronts from 12mm Hex to Bearing Wheels

I have several of the bearing front tires mounted from my B4.1, what would be the best way to convert a B5m to use the bearing front wheels?

Take a look at shapeways.com you can convert to imperial front axles using a dex210 conversion insert.

Starting to really get a hang of this buggy almost to where I’m almost over driving the set up. I think I need to go to stiffer springs due to two wheeling at times in the hook style turn at the end of the straight and lifting the inside rear wheel

I bought a new transmitter+receiver.
Now Im having problem fitting the new receiver(Futaba R203GF), its bigger than my old one. Ive been thinking of having the receiver mounted on the servo or maybe on the battery strap.
Has anyone done this?
Please post some pics about how you did do this if you had the same problem.

I'm using a old Futaba fm receiver and had the same problem. I have a 3D printer and created a box/cage that the receiver would slide into. I then mounted the ESC on top of the cage. The ESC sits right in the windows of the body. If you don't have a printer you could fab up something like that plastic, screws and spacers.

This is how mine is set up. On its side back up against the Servo. I ran into the same problem switching receivers. Instead of laying flat this is how it ended up

Looks good.
I see that you cut that plastic piece(the one inbetween servo and esc) on the front chassis plate to install the receiver that way.
I think Ill try that.
What kind of battery strap do you use?

I would assume that the battery is held in by double sided tape.

How well do these do in low to medium dirt track compared to b4.X or the rear version or even a b6? I want to get a couple of buggies for the family to play with at the track, ages 10 - 15. Also looking for best durability or inexpensive parts. The B5M seem to have come down a lot in the used market only a little bit more compared to the b4 I'm seeing. Thanks

I highly recommend the B5m over the B4. The B5m is much more durable and will work great on low traction surfaces with a little tuning.
