Easy to find spots to do it too as you only need around 50 metres of clear tarmac. 😉

 

This is the reason I gave up on speed runs in the UK, Drag needs much shorter roads..!!

 

 

P.S. Thought you might be interested in this, James has hit 200mph with his Hobao..!!!!

Went out today with the Infraction to test the new S1 GRP tyres, tweaks made to the XLX2 set up as well as a new car park to run in. 

Straight from the off it was going much better, ...the tyres got very sticky with just a few seconds warming them up and the car park had a much cleaner surface for drag racing down. Only downside was the useable area was quite short and not as wide as I'd have liked with some curbs to smash into. 

Managed a new PB of 2.41secs which has put me at the top of the FB 1/8th/1/7th UK drag racing leader board so pleased with that.

Not sure how well you can see the "Eleven's" but was pleasing to see.😁

Not so pleasing was this set though which was me basically hard on the brakes at 50-60mph odd trying not to hit the curb.

I failed. ☹️:lol:

At the last second I let off the brakes and turned hard left so it ended up being a kind of glancing front end/side hit. Think it caused less damage that way thankfully.

Definitely came home with some battle scars today but also a new PB and I definitely enjoyed it.

Just need to check all my geometry/suspension settings and repair the front splitter then do some more runs after that to see if I can improve on my time further. 
 

nice one mate! 🙂 

i just had a quick look at the photos and when i saw a chip on the pavement, i though' thats it, completely trashed the car' but upon reading the comments, i am very surprised it didnt do anything!

 

well done on the quick thinking, if it was me, i would have been somewhat dumbstruck and wont know what to do 😄 then crash it 😄

In my head I was like; "it's not stopping, it's not stopping, IT'S NOT STOPPING!!!!! :lol:

Letting go of the brakes and turning away was literally my last second ditch attempt at not wrecking the Infraction for the day. Was small part skill and large part pure luck honestly. 
I'm going to keep using the GRP as straightened the spokes out and it's still round so should work fine. 

Just need to check over the whole thing properly when I've a second free in case I bent anything I haven't noticed or some screws have come loose. Looks okay at the moment though thankfully.  :good:

was it like slow motion going towards the curb? 😄 

 

so not crashed the car and became top, i would call that a very good day 🙂 

 

i wasnt looking at teh spokes of the wheel on the last picture, i was looking at the wheel nut because i thought that was what you did when you hit the curb, glad you got the spokes sorted 🙂

It was a bit yep. :lol:

 

It did take a while to get that time though, ...I did loads of hits where I didn't even bother taking a screen shot of the result as wasn't happy with how it went. First time I've hit LVC on my lipo too in a long time as well. 

 

The damage was to the wheel nut as well as the wheel spokes.  Still could of been much worse.

@GMballistic are you running 6s or 8s ?? Nice to see you got top spot already 👍

 

Here's mine, but I'm running 1/8 scale distance 188ft.. SWB truck, R1's, stock Arrma BLX running 4s

That time wasn't the best I've done and I need to tweak the gearing a little, since then I have changed the spur but not run the car yet..

I'm running 6S. 
The "RC Drag League UK 1/7 1/8" (#RCDLUK78) on Facebook race over the 132ft.

I could try doing it to the 188ft distance but then it starts causing issues with finding a decent location which I don't want to do as that's the problem with speed running I have which is finding a safe suitable location. At that distance my Infraction would be probably clocking 80+mph odd.

I totally understand, i'm only doing the 188ft because the Arrma guys run to 188ft, to be honest 132ft would be better for me too because the road I've used it pretty short..!! 👍 0-40mph is quite fun too, the guys do that also and you have to have a pretty good launch to nail good times.

 

I'll try and put some runs in this coming weekend at 132ft and I'll let you know how I get on..

I don't do bookface 🙄

Top of the list! No1! That's brilliant mate👍 I suspect you have more to come from your infraction. Shame about the damage. 

i would be really happy about the damage considering what could have happened.

 

if it was me, i tend to have a slow reaction so the front end would be destroyed and chassis either bent or snapped.

New Contact foam tyres to try next. 
Hopefully they'll work well for launching but won't know until I try them out.

They look good anyway which is a bonus. :good:

Curious what shore did you get ??

I'm guessing these will be purely for drag..!! I have some 35's but not used them yet.

Well I wanted to pay for them using Nectar points on eBay and the only full set I could get was in 40shore hardness so I ended up going for them. I wanted to get the 25 shore hardness to be honest but like I said was trying to use Nectar points rather than my actual cash. 

The good thing is that if they don't work out for the drag runs I can at least use them for my speed runs. 😀

Today was a mixed bag, ...lot's of fun doing the drag runs but another set of tyres wrecked and a slide into a curb put a downer on it all. That's racing I guess. 
Just not sure if I'm going to keep doing the drag runs as cannot afford to keep buying tyres this often at over £50 a set.

New PB,

....and all the "eleven's" I left in the car park. :lol:

Todays damage: 1 wheel hex rounded, 3 tyres with chunks missing, XLX2 on/off switch broken, battery damaged (still useable), lots of scrapes and a damaged wheel hex.

Looks like this is turning expensive 🥴

How does your results compare to others doing drag racing?

It's getting very expensive ~ honestly I think I might just take a break, concentrate on my speed runners as I have an event in 2 weeks to go to and then think about how to approach it afterwards. 

 

We are no where near what the Americans are doing as well as some other countries. Seen lots of sub 2 second times for the 132ft using 1/7th scale Arrma's.

Doesn't mean we are doing that bad though just nothing world record beating. :lol: :good: 

Here is the UK Facebook leader board:

#1 James Rc Dnb, Arrma limitless 6s, 2.18s
#2 Gareth Monk arrma infraction 6s, 2.31s
#3 Phil Calvert, arrma limitless 8s, 2.45s
#4 Matt Willis, Arrma Typhon 4s, 2.65s
#5 Paul Baker, Arrma Infraction 6s, 2.65s
#6 Jas Sin, Arrma Felony 6s, 2.71s
#7 Ben Davies arrma typhon 6s, 3.00s

Potentially you could be sitting joint 2nd then ?

Are you running 6s or 8s ?

Sorry should of said, ....that is me in second place. :lol:  Hence the GM in "GMballistic", ...it's my initials. 😉 

I'm running 6S with my Infraction but my speed run Limitless is running 8S so I am curious to see how that would do. No way I am risking it though being this close to the first ROSSA Speed Run Championship of 2022.  Only 2 weeks a way now so that's my focus.

I see those numbers in that leaderboard and thought this week will be my time to run.. Checked the weather over my way, 100% chance of rain..🤨

 

Just to confirm you're running 132ft ??

 

Good luck for ROSSA..👍

Yep all done over 132ft. 😉

Thanks @Stormbringer and @BashingBrian for the good luck wishes. ROSSA is going to be probably the busiest yet going from the number of attendees. 
I'm running my Typhon and Limitless and hoping to beat my own PB's so nothing WR beating like some of the guys but it's always fun seeing everyone, watching the cars & generally just using the speed run RC's as they were built for. :good:

Shame wont see the dragfraction leaving fat 11's down the runway! Glad you had the fun with it, who ever gets it is getting a solid buy!

Cheers. Be hopefully doing it with the Limitless. 😀
