Futaba T6PV Officially Presented
The new 6PV mid-range transmitter from Futaba, previewed here just over two weeks ago, has now been officially presented.
According to Futaba Japan it will be available by the end of January.
Translated product intro from Futaba Japan:
T6PV – High-middle model with fastest response function
This is a mid-high class transmitter that adds elements of the T10PX to the operability of the T4PM Puls. The full-color display allows for intuitive operation. In addition, by supporting the fastest system “F-4G”, it is easier to feel the “feeling function” that gives stability to operation.
*The T6PV is a transmitter that supports “F-4G”, “T-FHSS”, “S-FHSS” and “MINI-Z”.
*The R404SBS and R404SBS-E are receivers that support “F-4G”.

Closer Look @ IFMAR Worlds TRF421
The IFMAR ISTC Worlds was held early November at Finishline RC Raceway in California, with Souta Goto from Tamiya Japan participating and TRF421 designer Takayuki Kono joining him as his mechanic.
During the Worlds we got a look at (one of) his cars(s), and his actual race car was then later displayed at the 2024 Tamiya Challenge Cup Final Race in Kakegawa.
Further pictures of this car have now emerged, allowing us to see more details of the car and setup used at the end of the Worlds week.
Compared to the Red RC Worlds photos, this appears to be another car, as there are slight differences in the electronics setup/layout.
The Red RC photos are from practice, and like most drivers they will have had a couple of cars to test different setups during practice.
On this actual race car there are several small differences, with for example different springs and a rear chassis flex plate.
In addition you can see setup differences if you look closely at spacers, screw positions used and so on.
On some of the photos the lower arms also appear more greyish, which would indicate a different material, but this might also just be due to light and reflections.
Personally I used the TRF420X rear chassis flex plate during testing this summer, but the one used here is specific to the TRF421 and longer.
In the photo below you see that it is attached with one screw in front and one rear, both on the centerline.
Above you also see the soon to be released aluminium chassis for the TRF421 (#42290 as reported first here).
The upper deck braces used front and rear appear to be 1mm thick.
All-in-all it’s good to get a more detailed look at Souta Goto’s TRF421 as it was finally run at the Worlds. Thanks to Rockwave RC for the photos!
Let’s hope that Tamiya in addition to the alu chassis also plans to release some of the other parts seen here, like the heavier battery holders, rear flex brace, knuckle arms, upper deck braces and/or different upper decks.
Kyosho TC Prototype – December 2024
Just a couple of new spy shots of the the Kyosho TC prototype.
I have already posted several times about this TF-8 prototype, and it still looks the same as in the last photos. But these most recent ones (December 2024) are a bit better quality so you see a few more details.
Still no information on any possible release, but these cars are raced by some Kyosho drivers in Japan for some time now.
TRF421 After Season Inspection
This year was obviously the first with the new TRF421 chassis from Tamiya, and I did quite a bit of testing with it during the summer, with around 150 packs or 3000 laps.
I recently took my TRF421 apart to check for wear after one summer season, and was quite surprised to find a very minimal amount of wear.
During testing I did not replace any major parts (except one broken rear upright and one wheel bearing), and the only real maintenance was to clean and re-grease axles, as well as rebuild the dampers a few times.
Above you see the motor mount and center pulley. The pulley still spins super free and there is only minimal wear on the side flange, but no visible wear on the pulley itself.
Despite coming with alu outdrives, these also show minimal wear both on the front spool and rear diff.
The diff, built with original o-rings and gasket, has also stayed consistent throughout all the testing. When checking weight now after the season it was 0.1g lighter compared to new.
The driveshafts are where you would expect most wear, but these still look very good.
There is some slight wear on the low friction cross joint and pin, but no real wear on the driveshaft itself.
The blades are the same that I built the car with. The “wear” you see is from sanding them when building the car, but wear during use has been minimal.
For the front DCJ’s it’s more of the same, with the wheel axle showing some wear, but the other parts show almost none. Most surprising is to see no rear wear on the alu cross joints!
The front blades that I used when assembling the car were some older stock ones that did not need to be sanded down , and on them you see there is almost no wear marks.
Both the front and rear driveshafts still have not really developed any play.
Both belts still look quite decent as well, but I will replace them for next season.
Damper shafts show some wear, but less than on some other cars I have used. Damper parts have for a long time been of really good quality on TRF cars.
What’s not so good though is they often leak a bit too much when built with standard o-rings. This I sorted early with using Axon OR-SO-001 o-rings, but I plan to experiment more next year.
One thing to note is that the ball quite quickly gets a bit tight in the plastic damper ends when dirt is built up (like in the photo), so it’s important to keep an eye on this as you want these to be free.
………………………………………………………………………
Overall the TRF421 shows very little wear after one season of outdoor running, which is good to see.
There is a bit more play in the steering, but for example the lower arms – or really the complete suspension still feels super good with no excessive play anywhere. Obviously the upper arms could be a bit tight from new, but if you want to remove this fully you can cut them like I did. On the other hand I also heard that the latest batch of these to come from the factory don’t have this issue anymore, but that’s just second hand information and I have not seen these myself.
Having now inspected the car, I know that I don’t have to replace many parts for next season, which is great news going into next season.
Hopefully Tamiya have some new TRF421 parts coming so I can instead spend that money on those!
