Muchmore Masters

May 13, 2013 Leave a comment

I haven’t posted in a little while but the site has been getting a good amount of traffic since I posted the 417 raceberry article, so I thought I would post a brief follow up. Since doing the conversion I’ve been busy testing both the hard and soft raceberry chassis and having good results with each. My lap time has improved by around 0.3s and I’ve been able to shave 4-5 seconds off my 5 minute time compared to the V5. The car seems both more predictable, and also more agile – it’s easy to drive fast and it changes direction better than before. This weekend is the first big test for the car with the annual Muchmore Masters event at the SMA track, and I need to spend the club race tomorrow evening and practice day this Friday deciding what chassis to run for the event. I’ll try and post some photos of my newly rewired car tomorrow, and some updates during the event as well. I believe times will also be streamed to LiveRC.com.

After the masters I’ll be packing my bags and heading to the US for the Reedy Race of Champions at Norcal Hobbies in LA. I’m really looking forward to seeing all the factory guys race again, and also to test my skills on what is sure to be a challenging track. I’m going in with really low expectations – I never race on treated surfaces or tracks with hard barriers, but whatever happens I’m sure I’ll have a great time and make some new friends.

Sorry for no media in this update, I’ll do some pics tomorrow! Also one shameless plug for the event we’re running at the end of the year, head over to http://ridenswtitles.wordpress.com for more details.

Raceberry 417 conversion

April 7, 2013 3 comments

I recently jumped on the raceberry bandwagon and ordered the 417 conversion kit from Tonisport (http://www.fast-webshop.com/tonisport). I must have set some kind of record in international post because it arrived at my house in Sydney 4 days after being shipped from Germany!

The pack contains (almost) everything you need to complete the conversion, including 2mm top deck, 2.25mm “standard” bottom deck, yokomo motor mount & centre shaft assembly, frond and rear belts, and some 1.5 shims. The only included instructions are for the yokomo pulley assembly but the build is straightforward – I did consult the BD7 manual to make sure I hadn’t missed anything. The belts included are a raceberry branded front belt and a yokomo rear belt. I did a little research and found out that the front belt is the same size as the long optional belt for the Corally PHI’09.

Image

I purchased the optional soft bottom deck too, which is also 2.25mm but a different weave and should provide more grip in cold and low grip conditions. Compared to the TRF417V5 bottom deck, the standard raceberry deck is noticeably stiffer, while the soft raceberry deck is a fraction softer than the V5 deck. This photo shows the different weaves – the soft deck is at the top.

Image

I’m using a 417X for the conversion so I can test it back-to-back with my V5. ┬áThis means there is a bit more shimming to do, namely 0.5mm under the bulkheads, and 2mm rather than 1.5mm between the bulkheads and top deck. I will order another V5 servo mount soon but in the meantime the Smokem mount also fits the raceberry chassis.

Image

The Yokomo motor mount is keyed into the chassis and everything fits very well, and the quality of the raceberry carbon is excellent. The internal ratio of the car changes from 1.94 to 1.85 due to the 20t centre pulley, so I’m using a 116t spur gear to get the desired FDR for modified racing. One thing I encountered was that the conversion does not include the 3x5mm button screws needed to mount the spur, and 6mm screws will bottom out in the pulley. I didn’t have any 5mm screws, so I had to dremel some 6mm ones to fit. The pulley itself has a bit of slop between the two pulley pieces, I’m not sure how to remove it so if anyone can help please let me know. The side-to-side play was good and I only added one 0.1mm shim. The rear belt fits well, but the front belt seems a little big and requires the eccentric holders to be turned 2-3 notches from centre – hopefully it doesn’t stretch!

Time for the suspension and electronics. There is less space to mount everything because the motor is further forward, but all my gear still dropped in fine. Something I noticed is that a normal antenna tube doesn’t fit through the middle of the top deck easily, so for the first time ever with a tamiya I’ve had to use the outside antenna mount! There is no hole underneath the chassis to adjust the pinion but you can reach it from the top – more or less.

The flex is quite different to the TRF417V5 when checked by hand, the raceberry car seems to flex from the motor mount forwards rather than straight through the middle as the V5 tends to. How will this differ on track? I’ll find out on Tuesday (weather permitting).

Imagep.s. I ran out of light to take a nicer photo, I’ll take some more of the final product in the coming days

TRF417 V5 Kit Setup

November 30, 2012 Leave a comment

Arn0 from Petit RC (www.petitrc.com) was kind enough to make an editable setup sheet for the V5. You can find it in the 417 setups page http://www.petitrc.com/reglages/tamiya/SetupSheetsTamiyaTRF417.htm

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 (www.rcmarket.com.hk) 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.

Image

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!

Image

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

Image

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.

Image

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.

Image

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.

Image

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!

Image

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.

Image

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.

I’ve been using Reedy batteries since TITC and I’ve been really impressed with their quality and performance, so when I was offered a deal with Ace Hobby Distributors to represent the brand I jumped at the opportunity. I’ll be running Reedy products at all major meets including MuchMore Masters and AARCMCC Nationals.

Reedy is a great company with a long and distinguished history, and ACE are big supporters of the Aussie racing scene. Click the images and check out their websites!
