    DB01-R "Evo"

    I'm skipping Step 2 for now as I'm still undecided whether to leave rebuilding the diffs as they feel pretty good. Step 3 is putting the rear gear cover and shock tower together. Im fitting a new shock tower as the one on the car was scratched from some "wrong way up" driving ๐Ÿ˜‰: I've gone for the kit standard carbon reinforced as these are super tough and stiff. I also have brand new wing support parts as these were on the parts tree that the chassis insert came on: The carbon plastic is incredibly tough, I should have pre-tapped the shock mount holes but I didn't have the tools to hand. The screw got pretty hot as I screwed it in! The first deviation from the R manual - following the RR instructions, in order to fit the big-bore shocks you need these little 3mm "stand off" nuts. The pack came with 10 but I only need 4 for the shocks. Some of the left over nuts will come in handy for another modification idea I have: The finished gear cover/tower assembly including new ball connectors: You can see the difference in plastic types here - the shock tower is carbon reinforced:
  2. I usually run RW in all my cars. Currently running one on a DB01-R with 6.5t motor with no ware issues.
  3. Just wanted to get some thoughts on this. I'm in the process of rebuilding my DB01-R (I have a separate build thread on the go) and I'm wondering whether to leave rebuilding the ball diffs as they are both super clean and smooth feeling. They were never an issue when I was running them in the car either, so I'm just thinking, if it ain't broke don't fix it. I guess I've put around 8 packs through them all told, so not sure what's best to do really?

    Tamiya DB01-R "Evo" Step 1 I Managed to grab 45 minutes this evening so made a start on the rebuild. I'll be working through the DB01-R manual as I rebuild but will refer to the DB01-RRR manual for the shock fitment and rear upright conversion. Firstly I'll need to remove the new parts from their packaging: Steering posts are first. I already had the Hop Up alloy ones but they were slightly worn, so I added a new set to my shopping basket while I was over at Plaza Japan as they were only ยฃ2: Next up are the alloy front suspension mounts. I'm re-using my existing ones as they had minimal wear: Next is this little fella, which I had to buy an entire parts tree for! It's the little plastic insert that sits in the bottom of the chassis. No idea why Tamiya added a slit in the chassis here, it's not like you can access anything! Anyway, you need to add epoxy over this once fitted, as it's still leaves enough gap for dust and debris to enter the drive train. My old one was epoxy'd into my original chassis, hence the need for the new one: Here it is fitted, epoxy to follow: Next we add the lower motor cover. I decided to re-use my existing part here as the wear doesn't impact the usability or performance, and I intend to run this buggy so it will end up scratched anyways ๐Ÿ˜‰: Moving to the rear of the chassis we now fit the alloy rear suspension blocks. As these were a bit more worn I decided to replace them with a new set: And fitted: In case you're wondering, I'm using thread lock for all screw to metal parts: Finally for Step 1 I fitted the new Hop Up alloy motor mount. These seem to be really expensive, around ยฃ35 - ยฃ40 here in the UK, and I've seen them as much as ยฃ60 in Europe. Luckily I spotted this on Tamico.de for ยฃ17! Aside from the slightly lighter weight and the lovely blue anodising I was surprised that this part wasn't actually as good quality as the original kit part. The kit mount has more intricate mouldings and just feels better made and more sturdy to me. I'm sure the Hop Up version is up to the job, but I was a little disappointed with the comparable quality. Either way, it looks awesome: This completes Step 1 of the build. I'll leave you with a few images of the main chassis at this stage. Till next time ๐Ÿ‘

    DB01-R "Evo"

    Teardown is now complete, so everything is boxed and ready for cleaning: Also, some parts turned up today ๐Ÿ˜‰: I'm still waiting on some spare belts and front and rear arms, these are due to turn up on Monday. As mentioned at the beginning of this thread the main upgrades will be the big bore dampers and the RRR rear upright conversion (this is what the TRF bearings are for). I was considering upgrading to the RRR full hex wheel conversion but I already have 2 really good sets of stock wheels and tyres, and I've never really had any trouble with the standard setup (even though it is a bit fiddly). Any thoughts on whether it's worth replacing all the bearings, as it's clear that some lube has escaped them and they're all a bit dusty, or is it just a case of clean and re-lube? Also, if anyone has any upgrade suggestions before I start please let me know, though they'll have to be cheap because I'm pretty much maxed out on how much I can spend on this now! More updates soon hopefully ๐Ÿ‘
  9. Hi Any build tips and oil weight setup tips for the buggy big bore shocks. I'll be running them on a DB01-R Thanks ๐Ÿ‘

    Teardown progress: Everything seems in pretty good order, though there's a fair bit of lube leakage from the bearings which has attracted a load of dust. Think I might sell the TRF dampers as they're being replaced by the big bores ๐Ÿ˜‰

    I have a very large consignment of parts waiting for me in UK Customs. Waiting for the inevitable customs charge letter to come through, hopefully early next week so I can get these delivered ๐Ÿคจ
  12. This is a known issue with DB01 hubs I think. The bearings are correct, standard axel size, used on pretty much all tamiya cars.
  13. Thanks chaps, that's really interesting. To be clear, the bearings are not worn, new bearings are loose in new hubs, so it definitely seems like this was deliberate by tamiya?
  14. I'm in the middle of a rebuild on my DB01-R and I've come across the fact that the bearings are loose in the front hubs. This isn't because anything is worn, it's like this from new (have tried a bearing on a brand new hub). The outer race is not a snug fit, basically has too much clearance. Now I'm thinking this isn't just an issue on my particular buggy, I'm guessing other Tamiya chassis suffer from this too. So I'm toying with the idea of actually gluing the bearing into the hub to stop the movement issues. Does anyone see any potential problems with this (aside from sacrificing the bearing and hub if they need replacing)?

    Does anyone know why my embedded photo's are appearing blurry on a PC browser, is it to do with Photobucket?
