The motor may be fitted to either side of the pod, either directly or via a spacer/plate(to prevent heat transfer and softening of the blocks, or for weight distribution) providing that there are no alterations to the mounting blocks.(Thinning of pod to give clearance to motor wires, drilling of a hole for access to pinion grub screw and/or addition of tie bar to prevent distortion are permissible)
No external bumpers are permitted, although a firm foam internal bumper is mandatory on the front.(10mm minimum cross section)

[stevo16v]

this will kill the mardaves,everybody at different speeds and nothin about lipo abuse,overcharging and heating them up to go faster ,tekin pro r1 is the best speedo there 120 plus 75 for a motor

[Gazza]

How can G2 and 4 cell kill the mardave ?

LiPo abuse is defo a no no same as all BRCA meetings charge at 1c why would you post that ?

watch this video of Nick and me

Nick is G2 4 cell and me in 13.5 brushless 1s LiPo

Tekin is the best speedo I agree . . . . . IN A TOURING CAR

Nick is car 1 i'm car 2

WHY OH WHY

Mardave is the simplest and cheeps form of racing
Why change it ????

All your doing is trying to re invent the wheel
the only difference between 13.5 and superdave is the motor basically as everyone will probually run the esc listed in the 13.5 class. superdave is what it says SUPER, use what you want (esc / Motor)


These are the rules on the mardave site

We have not changed it its still a Mardave with G2 and 4 cell but open your eyes there is a lot of clubs running 13.5 and LiPo they want it and we have gave it to them there is more people out there that just your self

All your doing is trying to re invent the wheel

But this time we have a rubber tyre on a wooden wheel

the only difference between 13.5 and superdave is the motor basically as everyone will probually run the esc listed in the 13.5 class. superdave is what it says SUPER, use what you want (esc / Motor)

I Agree but turn up and vote on it in October . . I hope you vote on it as I think its a good idea as well


These are the rules on the mardave site
http://mardaveonline.co.uk/2010Circu...sBRCARules.pdf

Read the LINK it says Proposed

Remember these are only set till october so please turn up and vote on rules at the AGM

[QUOTE 1=Gazza

Now that you have thrown your handbag in the corner. Yes my eyes are wide open and i have been reading all the posts about these changes. If you do not like people making comment's which is all i did, then why post things on here



the only difference between 13.5 and superdave is the motor basically as everyone will probually run the esc listed in the 13.5 class. superdave is what it says SUPER, use what you want (esc / Motor). How can super dave be super if you propose which ESc that people can use. Surely Super is any motor and any ESC with 1cell lipo.

I have seen what loads of changes to the rules did to touring cars over the years, dont let it happen to a form of racing which can introduce loads of people to RC racing. Which is MARDAVE. In my view as Churk said it should be as follows

Class 1
Standard Mardave
- G2 Motors Only!!!
- Any speedo up to price of £70RRP
- Original mardave Parts
- Original Mardave chassis.
- Any Servo

Class 2
13.5 Stock brushless
- 1s Lipo
- 13.5 Brushless Motor Limit. But no Price limit
- Speedo have to be non turbo etc only one on list or ones passed by the BRCA for this class.
- Any Servo
- Original Mardave Parts.
- Original Mardave Chassis.

Class 3
Superdave
- 1s Lipo
- Any Motor and Speedo.
- Composite Chassis Allowed.


[Quote Gazza ; Read the LINK it says Proposed . Quote]Oh and i do know that are proposed for the BRCA but i know that these are the rules that you intend to race at ardent


Im glad teamorsom96 agrees

agreed fella

[Gazza]

LOL OK no one likes a change . . .

So lets all go back to mud huts and horse and cart and no internet

We are humans we move onwards and forwards unless your IQ cant grasp that

[stevo16v]

4 cells and g2 is good but put it against a tekin r1 with 40 degrees advance and a short stack 13.5 motor and it wont be close,so spend £195 and win

Steve. . .

Tekin R1 is a STOCK ESC IT HAS NO BOOST OR TIMIMG and is a sensorless ESC

From Randy Pike as I asked him. . . . http://forum.teamtekin.com/phpbb3/vi...php?f=8&t=2975

"The R1 cannot run boost or turbo since it's a sensorless controller."

Hope that helps you all before buying one

One final Note:- I think the Guys did a good job try it and see then if you dont like it I hope to See as many of you at the BRCA AGM in October to put your views across and vote but untill Now thats it Guys

[stevo16v]

hes wrong ive got one,no boost or turbo but up to 40 degrees boost,dont get me wrong ,the proposals are good for people who are racing at the moment but u have to look at the bigger picture,mardaves have been around for over 20 years because there cheap.they are the basis of most clubs because of this.all thats going to happen is clubs will run there own rules and not drive the commitee forward.what about a voltage resistor that can be fitted to all cars controling the max voltage at the motor.it would bring all the classes together and stop the expensive motor and speedo,surly mtronics or mardave could sort something

Hi All

totally agree with you there

[truggy lover]

please please please re-read the thread no one is changing any thing under the proposed rules mardave as it is will not change as i have read it

only thing is to bring in new ruling on the 13.5t/lipo class so that they can run together and hopefully keep numbers up

i ran mardave as a 4 cell silver can and even at a gp at hinkley with hand out motors some peeps ran out side ran motors in in buckets of water others sprayed a full can of wd40 on a motor and when on track there motors were so much faster that wont change

with some one starting out with a 13.5t lipo setup they can gear there cars the same and race on a more even level whats the problem

PS i am not on the commitee just willing to move with the times

no more black art silver can magic and no more tending to nimh cells

just charge and race which is all i want to do

[dirtyghost]

Thanks for your positive support Chris.........!

And as for asking you, you were asked to be part of the comity and declined.(Not that it would be fair to have the company that makes the cars on the comity) but that's just my personal view.
Loads of people ringing you Chris... wot 5 people at most BT must be busy.

No one is changing anything as truggy lover has said we are just bringing things in line with current changes like lipo's and kit that's not from the ark, times change as do trends and peoples interests, this is being done to make things fair because at the moment if your not a wizz at brushed motor fiddling you have no chance, brushed motor's are far to hit and miss if you get a good one then you are ok for maybe 3 meets then they drop off brushless dont do this - buy one and use it for a few years perhaps.......... this has to be a good thing.
I myself have just changed over to brushless after running brushed for years, so much less stress in the pits after a race, no WD40 no com drops no cotton buds no greasy hands covered in oil and crud from the motor....... in fact i gave it a brush off and had a chat and caught up with some people i haven't had time to for ages in the pits.

Rant over cheers Marti.

[teamorsum96]

i here and read what your saying, and im all for change, but mardave is the simplest form of RC racing.the best drivers keep buyin new motors every few weeks, what do you think will happen with the brushless,they will just go out and buy new brushless motors every few months instead.

are club tryed the brushless and lipo, and it died off within few weeks lol

whats a good/cheap charger to use and what spec do i look for?

[truggy lover]

http://www.modelsport.co.uk/fusion-l...products/30776

i use this one 12/240v charger

no power supply needed and can run from a liesure battery if needed can balance charge as well can be had from £50 link just for info
