Thanks, any ideas would be great. I am going to upgrade to the 2.5mm chassis eventually, money is just to tight to order one right now. So I want to make this one work.

Adam - We had a guy that had a problem like yours at our last state race. His car would spin out in one direction and the tweak was hard to set right. Turned out he had a head on collision at full speed the week before and something happened to his lower chassis. If you have had a really hard crash you may have torn/shattered some fibers deep inside the lower chassis and this may be the problem. He replaced the lower chassis and the car was perfect again.

When is look at some of your cars i see that you are running an other carbon fibre strip. Or is it just the normal one without the curved part?

But will your battery well mounted than?

Chris P - Trust you to have a car that bright!! Gav is right though, blue spacers is not a good look.

It was a shame about the gearbox housings, they did look nicer, but hey i've got a set on my car and they're staying there

Gav - those plates we were talking about the other night, not good if you want to go higher than 1mm. Kills the droop apparantly.

Has anyone out there tried the diff with only 6 balls in?? I am trying to get some rotional mass out of the car and this seemed like an easy way to get rid of some.

Arjen - Personally i sue the std battery bar, just with the top spine taken out.

Arjen

thanks for your reply.

But is that strong enough to hold your battery on the right place?

Personally I run the spine because its a brilliant example of Cecil Schumacher ability to come up with simple but clever solutions to design problems. The battery strap on the Mission/Mi2 was one of the last contributions from Cecil before he fully retired.

Raul, I see your suggestions. Get rid of rubber? LOL. Actually I plan to use this as my foam car, but see my comment to Ottoman as to why I ran rubber.

Paul, I'll pick up a new body this afternoon. Have you tried the Parma Alfa yet? I was thinking about that and the Protoform Alfa. I really didn't care for the 6 the few times I ran it. I thought it had too much push from the middle of the corner out.

MattW

Yeah it is, but they can come out i guess if you have a big impact.

Adrian is correct that as it comes it is a good solution. It's kind of funny why i started running without it. When i had an Mi2 proto car, i got it without a strap, so had to use one of my own mission ones. However the strap is actually "upside down" compared to the mission, so i had to pop the spine out - and hence have never bothered running it since!!

btw, Chris P - just noticed that your car hasn't got purple Alloy nuts. Shocking

Arjen

Thanks for your help.

Last race i saw my weight of my MI2 and that was extremely much(1574). So i am looking for some things to get the weight much lower. But i don't want to spent 200 euro on it.
I saw that the steel driveshafts are 8 gramm each heavier than the plastic ones so i put my plastic ones back on the rear.


My equipment:

Sanwa digital fet servo
sanwa rx 311
GP 3300sp team batteries
revolution 12 turns
Lrp quantum 2

I run now 4 steel driveshafts
alloy castor/front,rear hubs.
one way
schumacher shocks
alloy 20t pulley
rear alloy pivot blocks.


Can you guys give me some tips on how to lose weight?

Dude, that's kind of personal, isn't it

MattW

Arjan, Not sure how your car is that heavy. Mine is about 120g lighter than that.

spec is something like this
Keyence speedo
KO 2173 servo
Novak xxl reviever
GP cells, Fantom Ti Motors

Teemu 2.5mm chassis
Ti driveshafts (frt), top deck screws, pins, turnbuckles

Can't think why your car should be so heavy.

Arjen

Some things i found was:

ti driveshafts are 10 gram per piece lighter than steel.
So that would be 20 gramm but 1574-20 is still 1554.
and 54 gramm is not just a couple of ti srews and turnbuckles i think?


What i also saw that there is an Carbon fibre battery tray and on mine carbon fibre car is an kind of s1 one wich was in the box.
I am running the standard carbon plates.

Arjen

MattW

yes, there is a carbon tray, but my car was underweight with the std one on as well.

My rear driveshafts are plastic. There are 4 pairs of Ti Hinge pins, and the same of turnbuckles. I also have Ti Ball studs. Not sure if this would all add up to enough.

Well my Mi2 is starting to stiffen up, I got the Teemu chassis and some carbon arms yesterday. Is anyone running a double upper deck to stiffen it up even more?

RCGaryK

I thought about it, but I also wanted to take a look at the holes from the Mi1 upper deck and see if they line up. Without all the cutouts, that deck should help rigidity as well
