Andreas W 1556 Posted August 31, 2022 Well done. Pics like these are making the TD4 grow on me. It is astonishing how much nicer the TD4/TD2 is looking, when you paint a roof on the canopy. Less spaceship/fighter jet and more car. 1 Share this post Link to post Share on other sites

To be honest, the stock system isn't really that bad IMO, after some getting used to it really isn't that hard. That said, I wanted to see if I could work out a system that: (i) would easily fit a shorty pack (ii) would be easier to install and remove (hopefully without a hex driver or even snap pins) (iii) would allow me to still run the driver figure (which I really like) (iv) would not require any cutting or mods to the chassis itself One added plus to this mounting system is that the space in front of the chassis next to the steering servo is now empty...Let me know what you think. I have some mods to test out to improve the dust seal of the gearbox too - this is a real pet peeve of mine with offroad cars with gearboxes that don't effectively seal out dirt. I've been considering doing something similar (especially considering the TD4 kit includes the TD2 parts for that area)...but, since I don't have a 3D printer, I'll have to come up with something different. Until I do, the idea I already have will work. As for sealing the gearbox, I've done this with other vehicles in different ways - electrical tape, thin foam tape, creating a (very thin) rubber 'gasket', rubbing a light layer of dielectric grease over the seam - all of which have worked. In regards to the TD4, as I haven't yet run mine, I don't yet know where dirt might enter, thus don't know which of my 'techniques' might work best. If you haven't already solved the problem on your vehicle, you might try one (or some) of the methods I use. Share this post Link to post Share on other sites
Panther6834 23 Posted September 4, 2022 Like a lot of us who've purchased, or considered purchasing, the TD4 Super Avante, the location is the battery tray, and how to insert/remove the battery, isn't exactly "ideal"...which is exactly why a number of TD4 owners have come up with ways of relocating the battery to the position it's in in the TD2 Astute. The "solution" several have come up with involves designing & 3D printing alternate parts. Unfortunately, a lot of people (myself, included) don't have 3D printers...so, we have to come up with other ideas. I'll admit I haven't looked at every alternate battery solution others have come up with...but, one thing I have noticed is that none of them (at least, from those I've seen) have used parts that came with the TD4...especially the side pieces intended for the TD2. So, I decided to see if using those pieces is even possible. Obviously, as they come, they can't be used, as they'd cause the buggy body to bow outward approx 1cm on each side. But...what if they could be modified to work? So, I decided to give it a shot...and, out came my favorite power tool for RC use - my Dremel. After removing a little at a time & testing, removing some more & testing again, and so forth, I ended up with what you see below. In all 4 images, the part on the left is the factory part, while the part on the right is the modded part. Yes, the body does still bow outward...but, by only 1-2mm. I realize that, by removing so much from the outer side, it would be exposing the ends of the battery...but, if I glue in a piece of closed-cell foam, it will not only protect the ends of the battery, but will also allow 'shorty' packs to be used without them sliding side-to-side. No need to constantly 'move' the shock tower, and now there's plenty room to install the ESC & Rx up front...all without having to design/print new parts. 1 Share this post Link to post Share on other sites
Panther6834 23 Posted September 5, 2022 Just a quick add-on/update to my previous post. After testing, to see if the above-mentioned mod will truly work, and determining it will, I modded the chassis pan & cross brace, to allow the use of battery posts. After those had been done, I put everything in place (minus the closed-cell foam blocks, which I still have to cut), including a battery, and this is what it looks like. At this point, I'm 99.999% certain my idea will work. 4 Share this post Link to post Share on other sites
BuggyGuy 1106 Posted September 19, 2022 Anyone know if the aluminium steering upgrade parts for the TD4 have the same geometry as the stock parts? And other than removing the stoppers on the front hubs when running universals is there any other way of increasing the steering travel? Share this post Link to post Share on other sites
BuggyGuy 1106 Posted September 21, 2022 Rebuilt ready for the first indoor race of the season this coming Sunday. Now running a Muchmore Fleta V2 ESC and a Speed Passion 13.5T motor. Shorty lipo installed up front with some lightweight foam blocks stopping it moving rearward. It's got DF03 shocks, a Kimbrough servo saver, UJ's, slipper TA06 gear diffs, and alloy servo stays in there too. Recently fitted the steel bevel gears to the props / gearboxes as well. Still got rollbars and a set off Schuey/Lunsford titanium turnbuckles with reinforced adjusters to fit. Not sure what I'll do next to it, it needs to go on a bit of a diet so I think some more alloy and titanium screws are in order, and I'm going to get a carbon brace cut to replace the front shock mount and another for the ESC tray / rear chassis brace. Not sure where else it could easily loose weight from. I also need to get some alternative slipper pads, as the stock ones don't appear to wear very well 7 Share this post Link to post Share on other sites

It looks like you can do a little creative material removal on the knuckles and caster blocks to get a little more angle, and DB01 knuckles look like they’d have correct geometry. Maybe. 1 Share this post Link to post Share on other sites

Carbon shock tower? The TRF201 front arms would be viable to fit I think, but the push rod for the front suspension would need extending about 5mm. Shame they are as rare as hen's teeth! DB01/TRF501/201 rear arms look like they might be an option at the back, but they have a bit of a gull wing near the rear hub, while the TD4 arms are flat so would need to test how that would impact the rear geometry (might require the XV01 rear hubs with an alternative drive shaft) - but the arms are quite easy to get so probably worth a go. Carbon shock tower is deffo on list - but the Tamiya version is on back order or not listed at all the European retailers I've checked yet :-( Exhaust pipes, driver, wheel arch mounts and the rollover bar are already ommited, but not sure I'm ready to take the Dremel to the chassis yet!

I took those battery tray ears off without fear, simply because the chassis is new and spares are going to be plentiful for some time. Also, you could go further and dremel the mounting points for the fender brackets v off of the hubs, because spares are cheap and available. Share this post Link to post Share on other sites
BuggyGuy 1106 Posted September 22, 2022 Anyone looking for turnbuckles for a TD4 - I'd highly recommend these, about half the cost of Tamiya items, and exceptional quality (Lunsford have been doing this a long time, I had their turnbuckles on an RC10B2) Also the TRF tool for fitting reinforced adjusters makes fitting ballcups super easy: A notch is present on one side of the turnbuckles so you can orientate them all in the same way more easily: Done: If you can't source Lunsford items in the right length (try DMS racing or MBModels) then Schumacher is also worth a try - I'm 99% sure they are made by Lunsford anyway and sometimes have a lower RRP and easier availability in the UK at least 3 Share this post Link to post Share on other sites

BuggyGuy 1106 Posted September 25, 2022 Halfway through first club night with the TD4, so far have broken the rear anti rollbar mount / rear bumper support after getting a gentle tap from another driver. This part will need replacing with something cut from sheet CF I think. Also have broken a rear hub, I had a spare with me so I'm not out of the running yet, but had 1 DNF of 2 qualifying rounds. The amount of slop in the car has gone up hugely after about 15 mins of total track time so far :-( It handles nice on a carpet track and hasn't disgraced itself - it's performance is mainly limited by my lack of talent behind the wheel, limited steering, and I've definitely not fitted a hot enough motor! 3 Share this post Link to post Share on other sites

Some other notes: - Though the battery is easy enough to remove, it's not quick enough to do between coming off your race and getting out to marshal. So that's a pain. - If you have rear stabilizer bars fitted, you can't easily adjust rear camber. - The stock TD4 wing kinks way to easily, definitely use the lower mounts, and TRF201 or racing wing kit - This chassis is very hard to work on at an event compared to a proper competition car. - The front stabilizer mount is not particularly good Things that I'll need to work on before I'll take this back to a track: - Part B7 is too weak, slight tap from behind broke this (probably need to get one of these in sheet CF) - Rear hubs are too weak, XV01 carbon reinforced or TRF201 alloy hubs could work here, but will require investigation. - Slop developed over the event that made it impossible to accurately set camber or toe - Mounting the servo on the right hand side of the chassis would help reduce steering slop. - Better mounting spot for an ESC needed in my car, I'm running a shorty lipo in a forward position, so removing the top deck and mounting the ESC on the chassis plate behind the battery could be a good alternative. - Not enough steering - Drivetrain has become super rough, suspect the idler gear in the rear gearbox, or wear on the metal bevel gears that will need to be shimmed out. Not giving up on the TD4, but will definitely be on the bench for a while so I can sort it out. Will move onto a TRF 2WD for racing until then. 3 Share this post Link to post Share on other sites

Busdriver 6209 Posted October 2, 2022 (edited) Just rebuilt my TD4 but wanted to have a bit of fun with it!!!! So we have TD4 chassis with Blitzer wheels( rears) with my last set of Dirt hawgs and my version of the Revive body. I had two plans for this. 1 was a P51D Mustang style with nose art or 2 to open up the cockpit and do something unusual. No 2 won. Made F1 style side panels for the rear wing and tried to do a fade from yellow to BRG. Happy ish with it. Not sure whether what stickers, if any it needs??? Any suggestions welcome. I will re paint the wheels the same colour. Update: Edited October 3, 2022 by Busdriver Missed a bit 6 Share this post Link to post Share on other sites

ThunderDragonCy 7885 Posted February 8, 2023 Any of you UK based TD4 owners upgraded to the carbon rear shock tower and got the kit tower spare? I would like to get a look at one and measure one up for this td2 based project. Would like to see if I can use the stock tower. Happy to cover UK postage and return. DM me! Thanks.
