Arn0 from Petit RC ( was kind enough to make an editable setup sheet for the V5. You can find it in the 417 setups page

As promised here is the full kit setup

TRF417V5 First Look (part 2)

November 28, 2012 2 comments

I continued the build last night with the front and rear uprights. Apart from the inclusion of DCJs there is nothing new to speak of until I encounter the floating servo mount. This is a great looking piece of aluminium, chunky as hell and stamped with the TRF logo – nice!

Unlike some of the aftermarket mounts available for the 417/417X, the V5 mount has a much larger offset between the two screws and includes a large peg that keys into the chassis. The result is a very solid mount that will not move in a crash.

With the servo mount secured the car was basically complete, so I attached the shocks and body posts and installed my electronics.

All that is left to do is solder my motor and put the car on the setup station. I followed the kit setup exactly on this build so I’ll take measurements of droop and toe and update the setup sheet. I also noticed I made a mistake on the setup sheet I posted yesterday – the kit setup does not have a bump-steer spacer on the knuckles, I’ll correct this once I have taken all the required measurements.

My first test with the car will be this weekend. After such a great build I can’t wait to see if the car is as fast on the track as it looks on the bench.

TRF417 V5 First Look

November 27, 2012 1 comment

Thanks to RC Market ( I was one of the first private buyers to receive my TRF417v5 so I thought I’d post a quick “first look” at the kit and it’s features. Apologies for the low quality of the pictures, I wasn’t taking them with this in mind.


The box is the nicest tamiya box yet with Jilles’ WC winning car on the cover. The box mentions some bonus parts but there is nothing beyond the features we already know. I can only assume Tamiya will do a lower cost non-premium package which will forgo some of the pricier option parts like the DCJs. Regardless, I didn’t buy this for any bonus parts, the value is great and it comes fully loaded as is!


First up are the carbon parts. As most people know the car features new top and bottom decks, but a surprise to me was the new front tower which sports extra inboard holes to allow the shocks to be further laid down compared to the TRF417X


The next neat feature I come across are the diff outdrives. These are all new for the V5, and have been updated to accept a 3.5mm delrin blade, compared to the 3mm plastic blades of previous models. I’m also pleased to mention that the tolerances have been greatly improved compared to the old outdrives. Tamiya supply a 3mm shim now (instead of 0.1mm shims), and with this in place there is the perfect amount of play without the need to shim the outside of the outdrive. The O.D. of the shim is still quite small, so I continued to use the TDX shims in my diff and the Kyosho #ORG05 o-rings.


In addition to being wider and made of better material the new blades are also much chunkier. This will no doubt be good news to anyone who has ever run the existing blades in modified.


The spool now features Tamiyas own steel outdrives. They appear to be excellent quality and are black coated. Unlike the Arena and Square cups they only sport a single set of slots, but they do feature 2 sets of pin holes for when they start to slop out. Time will tell how they wear.


Finally, I get to the highly anticipated “buggy” shocks. These are a big departure from what are generally accepted as being the best shocks in the business – the Tamiya TRF HL dampers. Compared to the HL dampers the new aeration style shocks feature 2 o-rings and a rod guide, rather than a rod guide/o-ring/spacer setup, and use an aeration cap with no bladder and a bleeder hole. To build them you need to drill/ream the hole on the inside of the cap, fill the damper with oil, screw down the cap, push the shaft in (oil spills out the hole) and then plug the hole with the small screw. The outcome is a shock that is very very dead, and in fact if you build it correctly you will get full negative rebound with the shaft being sucked back into the shock body. I found the more oil I put in the shock the more negative rebound I got. The shock itself takes a lot more oil than the old shocks, and I still found it best to shim the piston by 0.1mm to remove a little slop.

One other thing to be careful of is that the shocks mount with a 3x5mm button screw. There are only 4 included with the kit, so you need to be careful you don’t accidentally pick one up by mistake when you are using the many 3x6mm screws that come with the kit!


Another neat feature (not pictured) is that the motor mount and centre shaft stand both key into the chassis now with a small pin. This ensures they do not twist and allows the top deck to be mounted with only one screw each side in the centre bulkheads.


This was as far as I got with the build. I should be able to finish the kit in the next sitting. So far the build has been a dream, with typically excellent Tamiya fit and finish.

Last but not least, here is the kit setup. Note that the front shock position I have listed is for the X tower. On the v5 tower this is hole 5 (I think). The kit comes with blue and yellow Tamiya springs, but for asphalt I will start with HPI Silver.
