Does anyone know where I can get CVD's to fit my GT4? I don't care for the originals I have the hardened ones and they keep bending. Any idea's?

Unfortunately, the dogbone/axle setup is the strongest setup. I agree, the Yok universals bend very easy.

However, the Mugen MTX-2 front universals fit in the same bearing size for the front hubs. Another ex-GT4 owner has tried them with Serpent front one way outdrives and says he has ran this setup. I personally have not tried it. I think they might fit with the stock outdrives but you'll have to grind the dogbone ends to see if it will fit the Yok outdrives. I do know if you want a stronger axle, the MTX-2 front axle fits perfectly.

My Nova- 5P engine has lost its compression recently, it is a good idea to replace new sleeve & piston or might as well get a new engine for good. Will it get back to its original perfomance if I replace those parts??

Laugh if you need to.

Providing the bearings are in good condition still I would just replace the piston/sleeve but if the bearings are in poor condition I would get a new engine. It would cost you more than the price of the engine to replace both a piston/sleeve and bearings.

I think it all boils down to how much you can get the piston sleeve set for and how much you're willing to pay it... I find it unacceptable that you need to pay like 2/3 of the price of a new engine.

You can use any combination to mix and match the gears and pinions. Most people think you have to run the same number split between the pinion and spurs but this is not true. You dont even have to run the same colour bells together. The best solution is to test different combinations to find out what suites your track and how well your engine can pull the gearing selected.

The lowest gearing ratio being 15/18 and 46/49 with the high response set

and the highest gearing being 18/21 and 44/47 without the high response set.

Most engines have no trouble pulling a 4 tooth split in the pinions but some motors struggle when you go to a 5 tooth split. For most tracks a 3 tooth split is adequate.

Hi guys ! ...

Well ... i installed the 2 speed shoe type transmission and was time to test it ... its SHIFT FLAWLESS !! ... wow !! ... every time at the same point ... good job yokomo guys ! ...

Now ... after 1 hour or so of testing i decided to race on the local championship here in Sao Paulo (Brazil) ... its my first official race in almost 1,5 years after run in Spain on a Kyosho Cup. I was SOOOOO NERVOUS but the car handled like a dream so i decided to give it a shot ...

The race its a 15 minutes classification plus 30 minutes main (11 pilots tops). Through the all practice time the engine were running 230-240 F and running out of fuel at 260F tops so i was ok to the classification time ... i started and WOW !!!, the car dont even move ! ... it was running sooo slow that dont even the 2 nd gear kicked in ... i did 2 laps and entered to the boxes when my pits-man yell me ... "the engine its on 350F !!" ... ohhh my god !!! ... i run down the pilot stand and checked all ... the engine was SO HOT ... so i give it some air from an air compressor and put all the needle on closed position and re-positioned ... i dont know what happened ... once the engine was cool enough to try to start it i tried out and was ok, gave it 1 minute full throttle on the car stand and the temperature was Ok ... what happened before ?? ... I DONT KNOW !!! ... well ... all done and 13 minutes of the classification were out ... i did a couple of laps and stopped ... my racing position ... 10th.

Then i checked out all with my pits-man and all was ok ... its my first race after so much time that i was not preocupied about the finishing position so 10th .. "was good" heheheh ...

The Main race started and all were ok ... i did a great start and my position after the first 15 laps was 5th ... starting from the idea that the first 4th positions were ocupied for guys with national level and the 2 first ones with guys that have been national champions ... a 5th was ok for me so i tried to maintain the position ... i retained the 5th position for the first 17-18 minutes of the race ...

And then the unthinkable (it exist such word in english ?) ... one guy hit me on the rear going out from the last curve and I LOST A WHEEL/TIRE !!! ... wow man ... 1 lap without the rear-right tire and then a lot of time in boxes looking for a locking nut and on the process of put back the thing out and re-setting the toe-in rear right setup ...

After this i was back on the 10th position so i tried my best of not making errors and scale up a couple of positions ... at the minute 27 or so i was on 6th positon just by one lap over the 7th one ... and othe problem ... i started to feel that on the curves the car was opening itself ... ohh my god the batteries was my first though but i was pretty sure that they had full charge ... i started to drive a little on the slow side just to finish that 2-3 minutes of racing ...

Finally i ended in 7th place (yeah ... a big BUHHHH!!! for me but im still happy with the experience and adrenaline) ... when i went back to the boxes after the race i found the reason for the wide open curve problem ... the front right tire opened up (un-glued it) and I LOST THE INSERT !!! ... wow ...

Anyway ... now im relaxed and VERY HAPPY ... this its all on this hobby uh ?, a big rush of adrenaline ... i will work to improve my piloting and my problem-anticipation strategy ... i just checked out the car and i just have to change one front ball bearing ...

Thanks a lot guys for all your advices that always you gave to me ... i feel proud of belong to this community ...

by for now ...

Here are 2 things ... the link to one electronic car-racing magazine here in Brazil with the coverage of the race (im PATRICIO, the only guy refered as piloting a Yokomo) and a full view of the track layout for this weekend ...

bye !

Thanks for sharing your race story.
I guess, if you had fun, that's what counts more, huh?
Is it true that you're the only guy driving a Yokomo
over there?

Nice track! Seem like a lot of opportunities to overtake..

Tabushi was the only Yokomo driver in South America in area for a while but a local guy has just taken on the job of Yokomo dealer there and has been setting up a race team which Tabushi has been a part off.

I hope they do well.
