Yeah, I kind of thought the rpm would be heading that way, but I was presuming 5700 is no load rpm and with the tall gears (DF03RA gears) it wouldn't reach the 100k rpm limit in the relatively short space I had.

The max pro blurb pretty much says you can throw anything at it so...

Plus, if you're going to blow stuff up, better it getting filmed! 🙄

Cheers man, more of a guesstimate and finger crossing plus carefull to roll on the throttle and brakes to try and keep amp loading up to a min, and of course to keep the tyres from spinning up too much ( like the 2nd run on 3S did - 23 seconds in).

As for 6S, there's always that option if needed 😎😉

Yours should have the legs on the heavy weight df03, even if it is wrong wheel drive! 😜

 

Wooders that heavyweight DF03 of yours was extra heavy because it had all that extra voltage of a 5s lipo sagging it down but in trade off  gave you more power than the detriment of that added weight so that was a performance benefit I reckon. And you did that speed run in a relatively short area ( compared to my RWD runs anywy) thanks to 4wd being able to nail the throttle without the nose lifting at all and braking a lot quicker too.

El Dougo's realitely lightweight fwd did similar speeds but only on 2s lipo and without needing added weights to keep it down, maybe thanks to it being 'pulled' along by its front wheel drive system, if 300g was added to the car somewhere would the speed decrease? ( Couldn't see El Dougo's full run to see how much room he has start to finish due to fixed floor camera)

I think fwd cars can pick up speed quicker as they won't suffer front end lift from a sudden surge of power mid throttle will they?

My DT03 entry had to have extra 'dead' weight on the front to keep the nose down  which it actually dragged it slower making it less efficient, and being rear wheel drive was being pushed along by the rear wheels constantly fighting against nose lift taking much more distance to get up to speed than the other two due to power needing feeding on gently and also braking is awful on a RWD car, not sure what a FWD is like?

I guess the 4wd and fwd are probably  easier to drive for these high speed runs for these reasons compared to a RWD car, what do you guys think?

 

[Wooders28]

The downside of 4wd is extra overall weight, with an extra gearbox etc at the front, but the extra grip out weighs that in some cases, ie in WRC 

Brakes are a major plus though, full brakes and mine will go end over end.

Drag racing is about fast acceleration and speed, all the premier classes are RWD, where it's all about weight transfer and making use of all the power available. 

Ok, maybe slightly different in our case but physics is physics.

I played about with various suspension settings to get it to sit right under power ,although all testing was done with 3s,I lowered the ratio to try and simulate the hit (ended up with 3 hole piston & schumacher 35wt oil, stock springs on min setting on the rear and 3 hole with tamiya med green,3racing springs, 3 turns on the front).I tried 'fastrax arrow' on road tyres, but found the stock tamiya off road tyres better?? (Also those drag tyres, which even on part throttle where making the car jump being that out of balance).Ended up swapping in a brushless servo too as the steering was slow.

A touring car should be quick, being designed for that purpose, very light weight and aerodynamic but the downside of becoming very airborne at the slightest breath  ( I'm sure my schumacher fusion hit an ant once and went towards the moon 🙄).

I've a DT03 kicking about so i can try and get some pace out of a tamiya 2wd. Lets see how a 5700kv 5s powered neo fighter copes 🤔😀

 

[M 800STD]

With regards to categories, the two lists, T and non T with model codes works for me.

The only thing I would like to see added is another column with voltage used.

[El Dougo]

RWD is generally harder with big power but with a good set up (most likely lots of additional weight out front) overall there's little difference for straight line runs.  

I had a good length run up, and no weights as the motor is hanging way out there.  I chose the FF03 mainly for this reason, I had also been looking at the TRF419 as I think that it could be taken over 100Mph with 3s but it's too much money to use as basher and the FF03 came up at the right time.  

I would say 4WD is better in the vast majority of cases and especially so in overpowered scale cars. My HPI RS4 launches faster than a crazy super mega ultra fast thing.

Opinions guys on.......

 

the Top Speed entries  as:

"Fastest 4WD Tamiya"

and

"Fastest 2WD RWD Tamiya"

and

"Fastest 2WD FWD Tamiya"

and

 

Or is it getting tooooo categorised again?

 

What about categorising them by 'decade introduced'. This might encourage a few more 'vintage' speed runs. All credit to the guys pushing 60 & 70mph plus now with modern hardware, I'm waiting to see who is going to be the first to break the 100kph mark, but it would also be interesting to see the fastest original sand rover run, etc.

Like your thinking, would 'brushed' and 'brushless' work? 

With close to 'only' 40 entries (😮) I'm not sure how many categories there could be and keep things interesting.

Would a class based on a low budget work? Silver can class? Stock chassis (no chassis mods) class? 

It all takes time and effort to keep on top of all the potential categories, but I don't see any reason, with @Jason1145 consent of course, why we couldn't have a separate 'SPEED RESULTS' only thread with some of us policing each category. Ie, you post the 'vintage brushed' category etc? 

[Jason1145]

Ahhh I see what's happening the categorising is getting lengthy again lol, it's impossible isn't it as in, where do you draw the line? You've all got valid categories and in an ideal world we could use all of them but it might end up a bit hard to read on that first post that contains all the categories... the font and format just can't show info in vertical coloumns next to each other which works be the easiest way to show it.

Id have no issue handing over the ownership of the thread to share the policing and updating of it , say on a month by month basis for interested volunteers if it was possible?

Good question!

In an ideal world, a category for all budgets and chassis, to get more people involved.

I was thinking a separate thread for just categories and data, and leave discussions and run videos on this thread, to keep it less cluttered.

I'll update one if need be, I may have to remember how to use the old fashioned way of going online, and dust off the laptop!! 🤔

Why don't you bung all the data into an excel spreadsheet, with a columns for different categorisations e.g. age, drive system, powerplant, top speed, etc, then you could sort by the relevant columns, and then screen shot the spreadsheet and post it as a jpg. This would save a lot of time messing about with formatting forum posts, all you would need to do with a new entry would be add it to the spreadsheet and re-sort. If you have access to TC photos, you could just post the pictures into the thread, then when the results need updating, you can just update the jpg in TC photos and don't even need to touch the forum post.

[El Dougo]

It doesn't need to be complicated, just add the voltage as M 800STD suggested and be done with it  A  google doc with full details would be nice if someone is willing to pull it together!

I'm planning on running again on Saturday I'm aiming for 60Mph with a slightly bigger pinion, anyone else gonna run over the weekend?  6s Wooders  ?? 

Anyone got anything fast in the making? I seen further back in the thread a 4s M Chassis........... could be special!

I'm glad someone seems to have an idea what @MadInventor was saying, I was lost past 'why don't you bung all the data into an' !! 😯

I working, so i won't be for at least another 5 weeks until my nightshift weekend again.😔

Never say never!! 😉

[Jason1145]

If anyone wants to put all the data into an Excel doc and email it to me that would do for a start

But columns need to be decided first, model, battery, volts, decade, drivetrain, etc etc

I can sort them no problem and add as new entries come along but it's a lot of work to make the Excel sheet from now.

I've no plans to do any more speed runs now, I'm happy having the fastest RWD ( which is THE hardest type of RC car to speed run IMO) car on the list, when someone beats my DT03 then I'll consider coming out of retirement

Im waiting for that 4s M chassis to come along, and would love to see a Clod or a Bullhead on here too.

I've got a TT01 sitting here with a 3s and a 4750kv motor. Tested it last week and crashed into the wheel of the only parked car in the car park (apart from mine) lol....so only just repaired it.

 

Hopefully get a run tomorrow or Saturday. 50mph+ is my goal....I have a 55T Spur and 26T Pinion...about as fast as you can get without mods.

 

 

 

[M 800STD]

I might have a pop at this, 4s.

[Phil_H]

Disappointing 44.2mph from the TT01...

 

Had high hopes  

 

I've got a Video...but not sure I want to enter it as an official speed...It was pretty well planted, so I may upgrade the motor and go for it again. 60mph Goal 

[Phil_H]

Here's the Video...it is edited though, so if it doesn't meet the criteria then don't add it to the official list

9T Brushless 

3s Lipo

55T Spur

26T Pinion 

 

[Jason1145]

44MPH ain't no slouch, it's not a clean video so won't enter it on the list, best if you can rest the camera higher to show more of the action if your filming solo and can't mount it on you or the controller

Yeah, I knew it wasn't the best

 

I'm popping out with it in a bit now the weathers better, so will do a better one an see what I can do. Although new motor and ESC coming in a couple of weeks...really want to break the 60mph barrier!

[Macinnis]

The neo scorcher with full Tamiya branded hop up including tamiya gears and stock tires (motor mount is YR and uni's are Eagle) hit 77kph on a test run this morning.  Once I'm more confident driving that speed I will get video. I'm certain it will do 85 or so with other tires. 

[Macinnis]

I got a video of the TT02B on a speed run today.  It clocked 78kph (48.47 mph). 3700kv brushless motor, 64t Tamiya spur, 27t Tamiya pinion, stock neo scorcher wheels and tires, 3s 1500 mah lipo. 

Unfortunately it's a MS a body since I'm not ruining my neo scorcher body.  I'm upset as my first video was 79 kph but it filmed upside down and did not show zero at the beginning. I think there is another 10kph to squeeze out of this thing with a tire upgrade. 

 

[El Dougo]

A good day out today with my FF03 but lots and lots of problems ranging from my new wheels rubbing to the ball diff giving up. I managed a 59Mph run but didn't have the GoPro switched on ... just one of those days.  

I'll hopefully be back out on Monday to try and get the top of the board back  

[El Dougo]

Some footage from yesterday.

It sounds like your pinion gear is too tight. Is your motor mount adjustable?

She's definitely got legs! 

There's room under that body for for lipo's 😉😀

[Wooders28]

Quick question with regards to gearbox mods.

If i modify a spur from a 08 mod to a 05 (as I've lots of 05 module pinions and only one 08!) Is that classed as a 'custom' gearbox? 🤔
