Thanks for the feedback. Let me know if you think there is something I can add.

I plan to order up a new batch if drive shaft tips tomorrow. If there is anything anyone needs that is non standard (yok SD, Tamiya, large quantities), please let me know via email or PM as it will cut down the delivery timing to about 1 week. Thanks

Erik

I made a few updates to the web site including a picture of the carbon standoff set on a T1FK05.

New batch of TC3 and TC4 shafts should be ready by Monday...

I sold a few drive shafts to two guys from the Netherlands who plan to use them in high speed insane runs in a TC3. The stock aluminum shafts were going into harmonic (bending) at high speeds. Hopefully we will see what the shafts can really withstand -the ultimate test.

I also plan to revise the web site to make it a little more user freindly - all the pics take a little while to load. Let me know if there is something more that can be added. Thanks again.

Erik

I am interested in a carbon shaft for the PRO4. Do you have any?

I have one left in stock, but can make more to order if need be. $35 shipped to anywhere in the US. I also have TC3 and TC4 shafts in stock at similar prices. Email or PM me for more details is still interested. Thanks

fresh batch of TC3 and TC4 shafts just were finished up yesterday. Still working on a few more T1Fk05 standoff sets (should be done by Friday).

Have these shafts decreased lap times and does anyone notice a difference in acceleration and top speed. I run mainly 19-turn about med-high grip and was looking into one for my PRO 4.
Thanks.

Some people have reported a drastic improved accelleration, especially with stock motors. The savings is about 5grams of rotating mass for the HPI pro4 and closer to 9g for the TC3/TC4. I have read that rotating mass savings is similar to a 10 fold static mass savings. So this would be like removing 50g (2oz) for the Pro4 or 90g(4oz) for the TC3/TC4. For a touring car weighing in at 50oz, that is a 4% reduction in mass for the pro4. It is a great way to improve HP/wehight ratio that doesn't degrade over time like powerful motors and batteries.

Any of the other CF shaft owners want to share any thoughts?

I hope to have the web site updated and more user friendly this weekend. I will keep everyone posted when it is up.

I shouldn't worry about breakage than right as far as under stress from motor not meetings with the wall since its only 19-turn?

I have only had two reported broken drive shafts. One I personally watched the destruction to the rest of the car. The driver was having handling problems and managed to break the car in a qualifier. After the initial impacts and damage, the driver repeatitally rammed the car full speed into the wall in discusst, instead of pulling off early. It came off the track with a missing the right front suspension (arm, knuckle and wheel were missing), a cracked left rear arm and other internal damage. The shaft splinted a little on one end and popped the glue. We reglued the shaft and it has been still in service. Infact, he purchased 2 more after that insident (a spare for his car and one for his son's car). Another had a similar issue where the driver hit the wall hard over several weeks. Again the glue just popped free and it was successfully glued back together. Both of the effected shafts were prototypes in TC3s and I beleive I have corrected the issue with stronger adhesive and a slight tapper on the tips. The TC4 FT, HPI Pro4 and all the other double decker chassis protect the shaft much better from impact due to significately reduced chassis flex. No problems are expected in these cases. If you purchase one, I can garrentee it will not break for 2 weeks. If something happens, send it back and I will replace the Carbon Center shaft. That is better than most manufacturers/aftermarket companies as I don't know of too many that will replace parts when the driver breaks them (Traxxas back in the day comes to mind). Anyway, let me know what you guys think.

FYI - I hope to have a report from some lads from the Netherlands running the shafts in 80kph insane speed runs this weekend. Stay tuned.

Hope to have the web site updated tomorrow. A few technical difficulties delayed it from last Friday.

I got my standoffs for the Xray last week. I checked them all and they were exactly the same height. Lighter and stronger than the alumn ones that are stock.

Thanks for a great product.

Glad you liked them. Every set for the T1FK05 are matched to within +/-0.025mm. As every part is hand made, I can touch up the lengths as needed to get them very close to the 35.5mm length (what Xray intended). I found the stock aluminim parts are closer to +/-0.1mm in length.
