Which region in the Ph still play tech race using those very simple setup (9mm front, 19mm mid, rubber brakes rear)? All of them have identical setup, isn't it a tad boring like that? hmm.gif

When the local racers here attended a big race in Manila, they told me that there was a tech race. The particpants were around 5 to 10 but ea. believed to have 20 cars which took the race 'til midnight O.o The rules were 4 rollers only, not sure if there are motor restrictions.

Later, there will be a unique category wherein cars will bumo each other (1st time trying this category). The cars that will fly off the track or pushed 10 panels back loses.

MS Project update

Finally, I was able to buy T03 / N03 and made a test run. It was able to run on the track 17.75 secs (The best time is 16 secs up to date w/ a VS chassis which I posted earlier) w/o fully charging my battery. The trick I learned with this project is to make both rollers contact on each wall track ensuring stability. Also, since the rollers contact the track wall all through out, no impact during the curve which cause power loss. It was the same setup is done with the Indo cars which are amazingly stable even with their freaking speeds and rewinded motors (best time on same track was around 9-11 secs on what I heard). On the previous races, winners of the high speed make the roller width contact the track walls all throughout which I assume it is the main cause of gaining speed. This setup violates the Japan Tamiya rules regulations, however.

This is how High speed rules defined here in the Philippines I believe because the rules was set since year 2000 (not aware of the official rules back then or not existing on that year, perhaps?) and most of the racers were old school which they maintain the same rule:
8 roller setup allowed
Roller width limitless

Speed tech races are strict with official rules. Not sure only with the roller hole placements as long it complies with roller width.

Technical setup has 4 roller and motor restriction. No further info. about this bec. I haven't participate and no tech race has been organized near our area (nearest tech race is 100 km away).

Front roller angle : 4.5˚
HD3
All super hard
3.5 gear

My VS still can't clear LC. Hahahahhaa.

The organizer is replacing back the rainbow change lane to the standard bridge change lane since the 16 secs best timer is unbeatable. Too bad the MS T03/N03 part came late which I was not able to race it. What I noticed before with the standard bridge change lane, I used black sponge on both front and back of the MA chassis to survive the change lane. I am very interested on testing the monobar setup from Italy which is meant for the change lane. I haven't seen any local here doing that monobar setup. But on the previous races, the winners had roller width contact the walls allthroughout the race.

Hello all,

It's been awhile and here are the outcomes so far:

MS Project is worked like a charm on my high speed races. I almost won but on the finals, my car dropped speed (9 laps) so I won 2nd place.

On our high speed track, we had this very peculiar obstacle, 6 straights > LC > curve. My MS Project was able to overcome that obstacle with a 8 pcs 19 mm roller setup. However, the race organizer adds rules every week. Now, the rules are now 6 roller setup w/ no front brake. Both of my MS and AR are unable to pass the LC when the battery is fully charged.

I am at loss on the 6 roller setup. Thinking if I would try the Italian monobar setup with that obstacle. Any suggestions specifically for AR? I am leaving the MS project as it is since they might put back the old rules. Pics of AR setups will be good too smile.gif

max rollers should be 6 in total.
if youre into high speed LC.
u shud go for italian setup and MS is the best candidate for it. smile.gif

QUOTE(soulfly @ Apr 8 2015, 11:07 AM)
Italian setup is pretty much the solution for high speed LC using fast motors like ultra dash or plasma dash
*
Ah ok. I thought there is a different setup for that. For some reason, 2 racers were able to pass it w/o using a monobar setup. Both of them became finalists and won the race. 1 is using Super 2, the other is MA.

I spend hours on the track making mine stable, but on full battery, it just flies off *facepalm*

My MS project can't adapt the Italian setup I believe. I am using bumperless on both front and back.

Anyone tried 4 roller setup front and 2 roller setup back? Is there any advantage on such setup?

Tamiya Jump Track
Hello guys,

Have you ever tried these set of jumps (see link for pix if not shown)? They added these jumps with the same track setup of 6 straight panels - change lane - curve.

My car is more stable when the rear lands first. I put black sponge brakes at the front to withstand the change lane bridge. If the car front lands first, it tumbles. Any suggestions on how to make sure the rear lands first? My guess is to put dampers at the rear.

Problem with these jumps is that the jump is so low, with a slow speed, it hits the center chassis whent he front tires has passed, and then front lands first, hitting the front brakes and then tumbles. I am already using Ultra Dash with Super Large Tires and 3.5 gear on AR chassis.

Used the box stock 60mm shaft la. Paint marker on the shaft, not permanent marker pen. Paint marker have thicker consistency. Rim locks on nicely on the shaft.

I just want to verify, the pens you are referring is to keep the rims stick on the shaft right? Regarding Paint Markers, do they have types? Or any paint marker is fine? I am just worried if the plastic will melt since we are talking about paint.

Hi Guys,

It's me again with a question. I hope you're still active even though I read a lot of closing shops on this thread.

How do you reinforce the front of Super FM? Speedtech racers here restricts drilling holes on chassis. So the Youtube video I saw is not applicable where in you drill a hole and screw the FRP sad.gif I mentioned to them that Super FM should be at least allowed just to reinforce as we all know it easily breaks. Isn't it justifiable? And then they overprice and hoard Carbon FM from $5.00 to $15.00. *pissed* Even 2nd hand Carbon FM's are around $15.00.

Some sharing on my setup for AO Jump ramp biggrin.gif

I wish you have a video of your car jumping on the ramp. Same here, my car tumbles like on the video on my first try on the ramp. In the end, we all made our cars slower to prevent it to go off track.

take the frp and cut it to shape , or soak some cotton wool in superglue and put it in the front (rule dependent ) or use putty and reinforce the fron area .
*
Any videos or pix about it? I heard about cotton and super glue. You mean you put cotton underneath the FRP plate and inside the front bumper?

What about the FRP and cut to shape?


QUOTE(iOnine @ Jun 18 2015, 08:11 AM)
as le above.
depending of rules as well.
i wonder why u guys dont allow to drill hole ;(
overall, its still tamiya and the japaneze loves to drill and cut and paste alot!
meaning ur rules is much more superior than the japs -.-'
*
All I can think of is unjust marketting. Unjust because u tend to buy FM chassis but CFM are hoarded and overpriced. Local speedtech racers here said that they are following the "Manila rules" which they also follow Japan Rules. Japan Rules with extra restrictions. I just also heard that Super XX EVO parts are banned for race here O.o

Hi,

My MS project won 2 times in a row now smile.gif All were happy watching because it gets to the first to the first position at the last lap (6 lap race).

Now I am building another MS bumperless project (happy with the MS project). Has anyone tried putting Front Under Guard directly to the FRP on a bumperless setup? I am planning to make a speedtech bumperless MS. The reseller is discouraging me to buy HG FRPs so I am planning to buy the #15452#15452 both front and back, screw the front FRP at the bottom of the bumperless, and then screw the under guard to the FRP.

Btw, is J-SPEC tires (tires cut to 3 mm width) not ideal for speedtech? Why?

plenty of japanese racer use that spec for speed tech, i don't see any problem. the final result depends on the overall setup of your car anyway.
it's the thickness that matters. if you're referring to 3mm width but with 35mm overall diameter (also known as ultra-wide diameter tires which often used for high speed races), that is less to be desired because the thicker the tire is, the bouncier it will be.

but as per Japan standard rules, you need to add at least 5mm 'dummy tire surface' to the 3mm tires so that the overall diameter meets the minimum requirement which is 8mm.
*
Yes, I am referring to the 3mm width. I am just wondering whether to buy same set of tires retaining/not cutting the width (and then trim) or use my current 3mm width tires for speedtech. People here are trimming their tires. I do not have the skill / experience to do that so far.

What about the front underguard under the FRP?

Silicon tires warms up faster thus having more grip compared to rubber. But if you have a long circuit and the silicon tires are not taped it might come off easily once it warms up (getting loose). It's okay for lower speed layout with many jumps or uphills, but the advantage is not by much.

There are a few different reasons we want to use low profile tires.
1. Soft rubber tires are generally bumpier especially when combined with plastic wheels. Trimming it to low and absolutely flat profile it gives more surface area which is more stable when landing from jumps.
2. Reduce overall wheel+tire diameter for lower center of gravity and slightly faster acceleration

Carbon brushes wears out faster than copper brushes, but the more it gets worn, the better it performs (more surface area touching the terminal) until the carbon finishes.
*
How do you know if it is silicon or rubber? Or are you referring to the Pneumatic tires? Are XL tires trimmable? They seem low profile but still bouncy on tracks

Hi Guys, it's me again

MS Project (Speedtech version)
I am facing a hard time with the MS Project (speed tech version) I am making. The setup is has a good landing on the jump ramps (the orange ones). However, it "long" jumps on camel back jumps (slopes) passes the 3 straight panels and misses the corner. I am forced to use light dash motor just to barely land before the corner but my rivals are using ultra and mach dash. I am thinking of adding black brakes at the front but maybe you have additional inputs on the setup I am making.

Attached photo is the speedtech version. It's MS-L and bumperless.

MS Project (Softspeed version)
I am facing dilemma also on my previous project. Now we have new pro players, my car seems to be left behind. I am thinking that I am retiring this project since the new players have fully tweaked their single shaft cars which is why my dual shaft car will never win. Do you think a dual shaft car can outrun a ultra dash motored car?
