Rallycross RX at Mendip
Time for a bit of a edit on my original post now that we actually have peeps with cars that want to race .... and still growing interest in the class !!!
So, some general guidelines for the class to get us up and running ... and this is only guidelines mind !! We want to follow full sized Rallycross RX as close as much as possible as it really is a great class .. ie. big power, low grip, short multi surface tracks and lots of proper racing !!! So the race format will be four qualifying rounds of 6 lap races, using the round by round system, with 3 rounds to count and 1 drop score. This will give points in each round that count towards the main finals. All starts, will be mass starts, (yay old school !!) comprising 2 rows of 3 cars, and these will be switched each qualifier ... Finals ... not worked that out yet but most likely a slightly longer race than qualifying, so maybe 8 laps .. and depends on the track .. .. and we'll also have the "joker" lap ... Car specs - Shaft drive rallycross style buggies converted to run on mostly tarmac tracks .. no belt drives .. 4wd recommended !! Cars must run rally or rallycross style bodies .. or generic types like the Hyper GT rally or Protoform rally bodies .. Max 3 cell lipos ... there was some questions about whether we have to run hardcase lipos but the word from the BRCA is that soft case lipos are OK, we would recommend some extra layers of heatshrink on these for some extra protection .. Motors - sensored or sensorless , max 2400kv .. these are bonkers fast so not sure why anyone would want anything faster ! Tyres - after some research, our ideal spec tyre, is the GRP Revo cut slick rally tyre in S4 compound. These look realistic and give good grip when they get up to temperature but are still slideable ... and are said to last a whole season !!!!! If you only have kit tyres .. its not a problem .. run what you have for the time being .. Hopefully our local model shop RC Octane will be able to stock tyres for us in the near future .. Think that's it ... please post or message me if you need any info or have ideas .. Below are the club race dates that we'll be running Rallycross on during the summer - 15th May 19th June 3rd July 17th July 21st August 4th September Some of you might have seen me playing around with this on the onroad track over the last couple of months ... and at the weekend of the 4wd regionals there was a LOT of interest in the car.... and several guys talking of buying cars and running some Rallycross RX style meetings using a shortened version of the the onroad track. So I thought I'd share some links for cars, tyres motors etc .. and see if we can get this off the ground !! http://i.imgur.com/XWbdN96.jpg?2 |
Mine was a 1/8 buggy that was converted to run onroad, but there are a few rally style cars that come ready to run ..
Cars like this - http://www.rccaraction.com/wp-conten.../basher_cc.jpg http://www.hobbyking.co.uk/hobbyking...arehouse_.html or this DS3 style .. http://1.bp.blogspot.com/-p-qtjWxV4o...RallyCar-1.jpg http://www.the-border.com/HobbyTech-...ce-Roller.html Hyper GT rolling chassis .. http://www.wheelspinmodels.co.uk/i/229370/ http://www.ofna.com/images/hyper-gt-...t-side-750.jpg |
Here's a video of some 1/8 rallycross from France ??
Gives some idea of how they handle and how fast they are !!! https://www.youtube.com/watch?v=4fORydB-GcU |
... and a few links to the gear that I've used .. you'll see how cheap it all is ...
and speed wise .. running at the weekend my car was only a little slower down the straight than a local National TC a finalist running a 4.5 motor on boost !!! and probably quicker out of the corners !! This my motor - http://www.hobbyking.com/hobbyking/s...or_2400KV.html and fully programmable 150 amp speedo - http://www.hobbyking.com/hobbyking/s...arehouse_.html Lipo - http://www.hobbyking.com/hobbyking/s...Search=Z58003s Tyres area nice realistic GRP cut slick, I use the S4 compound, they grip pretty good but still allow a degree of drifting :) They work out around £33 a set posted, and are said to last a whole season !!! http://www.grpgandini.it/index.php?p...emid=6&lang=en |
This looks great, have raced 1/10th off road and 1?8th nitro off road in the past but havent raced for a couple of years since I retrained as a train driver and moved house, but this would definitely convince me to start again.
|
There's a few of us have these now, so hopefully we'll soon have some organized racing with them !! :woot:
I really enjoy running my car around, only been on my own so far, well I've practiced with a few TC's but the 8th tends to scare them off the track !!! Keep an eye on here or Mendip RC Raceway FB page for more updates .. |
Is there anyone who brings the tyres into the uk?
|
Not that I know of, there's some on ebay but its cheaper to buy direct from GRP in Italy !!

link to some pics from our first test run on sunday - https://www.facebook.com/media/set/?...9926303&type=3
The Hyper GT seems to handle really well out of the box with a few setup tweeks to diff oils ... |
Excited for mine to arrive now! Full heat of 10 of us soon?! :thumbsup:
Would it be worth us getting a list of names together with people who now have a car? Just so others can see the number of people that will look to be racing them? |
Please check out the start of my first post for details ..
|
John at RC Octane will have 6 of the Hyper Gt's coming in very soon if anyone is interested .. these seem to be very good straight out of the box and great value too .. :thumbsup:
|
A little update to show you the runners and riders in our rallycross class ..
Si - Ofna GTP Dan O - BSR Rally (basically Team C buggy with a different name !!) Andy G- BSR Rally Ben G - BSR Rally Dan H - Hyper GT Steve H - Hyper GT Brian B - Hyper GT John H - Hyper GT Joe W - Hobbytech STR8 .. or maybe a Hyper Gt .. or ... Jay - Associated Pro Rally Rick - BSR Rally |

|

Will do my best to get al9ng and try this. Looks great fun and lot less serious than buggies :)
|
For people looking for bodyshell options, I quite like the look of this one from Protoform named the PFRX :thumbsup:
http://www.ebay.co.uk/itm/2721130600...%3AMEBIDX%3AIT http://i.imgur.com/hDGWEAa.png Just out of interest. Is anyone considering using a short course truck for the rally cross class? Being the same dimensions, you can add a body shell and some 8th adapters for tyres! |
11 of us with rally cross cars now :thumbsup:
|
1st round of Rallycross RX at Mendip THIS weekend !!!!!!!!
.... can't wait :woot: |
Best finish building my car! Rallycross is on!
|
Here's a link to a "speed calculator"
I've used this to work out overall top speed, and initial gearing for my cars setup, I aimed for around 45mph and this seems to be about right for rallycross on Mendip short track .. http://www.scriptasylum.com/rc_speed/top_speed.html |
Our first round of Rallycross RX proved to be pretty popular straight off with 8 drivers turning out to run the 8th scale beasties !!!
The Hyper GT's looked good straight out of the box with most using the standard electrics listed above ... The BSR's looked to run quite well and should go even better with a few tweeks .. some softer Hyper GT springs should work well as the std car is quite hard ... Nearly everyone was running on the amazing GRP S4 compound cut slicks ... grip was great after a couple of laps on the tarmac .... but not quite so good on the grass :lol: .. and here's a short vid of the days fun and frolics ... apologies for the dodgy editing !!! https://www.youtube.com/watch?v=Ia9r...ature=youtu.be |
Nearly 1000 views :woot:
Someone's interested !!!:thumbsup: |
We need to talk bodies seeing as there really seems to be a growing interest in this class.
Choice isn't great really, stock Hyper GT actually looks better painted up in some decent colours in the flesh .. https://scontent-lhr3-1.xx.fbcdn.net...60541750_o.jpg |
Associated Pro Rally body .. although a little pricey does a very good job of looking like the VW Polo rally car ..
https://scontent-lhr3-1.xx.fbcdn.net...25673310_o.jpg |
Hobbytech DS3 would look amazing painted up in Solberg colours .. need to save up a bit first !!!
http://img.xooimage.com/files90/5/d/...3--3d1c54c.jpg |
There are plenty of body options available from Delta Plastik
http://www.deltaplastik.it/?p=prodot...at2=11&cat3=15 |
:thumbsup: and not a bad price either, even shipped from Italy !!
The italians seems to have the majority of good body options .. BYSM make some tidy bodyshells .. Scooby - http://www.bysm.it/immagini/7gt/100D0432.JPG |
Audi would paint up nice in Mattias Ekstrom Red Bull colours
http://www.bysm.it/immagini/9gt/100D0439.JPG |
|
Looks Good, will have to save some pennies and get one in the near future .... will stick to our 1/10th Rallying at the Mo ...
|
Good to hear that :thumbsup:
They're not expensive to get up and running, plenty of 2nd hand stuff on ebay as usual, thats where mine came from !! |
