also comparing your car with Glenn's he has much less wiring within the vehicle, I'm sure you could shave some more weight off there. . Addressed that on Saturday Matt; I could tell you were not impressed ;D oops need to reweigh to mak sure I am legal  |

Some good points there Ed. Do they do titanium screws in orange?
;D

Thanks for the info Glen, much appreciated. We run the Pearl, which at 30gm could have a penalty, our KO VFS1 was 18gm. but apart from that...
I guess I could take off the microchip telemetry stuff but the advantage of being able to modify Craig's droop and rebound on the fly would I am sure outweigh any gain from the small weight reduction

I was just looking at a pic of your 009 Pete, lose the excess wiring, fan, the battery strap and all the weights and you should be able to lose what you need?
Your speedo isn't too heavy, you don't even have a heatsink and fan on it. Brushless speedos just aren't light...
Your servo is a full sized lump though, compared to a low-profile one.

Wiring sorted Simon But yes my expensive 1 season old KO servo does carry a 10gm penalty. But that's the rub Simon and brings me back to the point I made right at the start of this thread. Does our sport really need such a severe rule change that is going to force those that want to be competitive and are competitive(and I mean in relative terms) to start spending large sums of money to remain competitive? Especially given the current economic conditions and issue in attracting new people to an already expensive sport. Glen's results suggest that if you are 50 gm off, ie 1400, you will be a third of a lap behind. How would you feel if you are consistently battling with Reuben and then find yourself consistently 5 sec adrift? (no personal point there just an example ) Not too happy I would wager. The results of the poll so far suggests that the membership agrees |

I run the normal sized KO servo's as does Chris Grainger, Olly and Elliott. They have all tried the small ones but prefer the larger ones. So I wouldn't go changing your servo in a hurry.

Ahh, even big servos are possible :-)
So Pete, I think we've proven that one DOESN'T need to spend lots to get down to 1350g.
It seems anyone should be able to do it sensibly.
So is there a real problem with the 1350 rule? I don't think so.

The results of the poll so far suggests that the membership agrees Good news for you pete is that I may be 50g off without buying titanium screws and lightweight bodies with almost no paint. so no pressure there! I must agree that 1350 does seem a little to light considering the weight of motors / shells / esc's. also how much in the weight of tyres is this going to effect different series? im sure some brands of tyres weigh more than others. Ide happily vote 1400 at the lowest, but 1350 starts looking expensive. |

reuben , have you run the car at 1350  also the std schumacher is at about 1385 ish so with a light weight shell you will b about there ! i think you will find there is only about 2-3 g between wheel/tyre combos (pre built) so i cant c that being an issue . b4 you all say 1400g is best go run your cars at 1350 . |

John, I am not planning on replacing it Simon, I disagree. Glen and Ed (and Les?) have"proven"it can be done. Reuben and I (and Chris?) have "proven" it cannot. The subject to prove is that everyone without significant expenditure can do it - otherwise the concerns are valid Personally I consider dumping a good £100 component for another £100 component to be significant. Especially when I have to spread that across 3 cars. Glen I don't think anyone is saying 1350 isn't the "best", just that how does one get there with certain cars and configurations. The good news is that Craig and Reuben will be able to chase each other around the track without spending any money ;D And Reuben you can get a spare 10.5 with the money you are saving |

Pete my results confirm Glens with the Mi4,around 1380 with similar gear,but the chassis is slightly motor side heavy(with Lipos correctly fitted)....My Photon can easily make the weight with spot on lateral balance even with a heavy GM esc...double check your scales I cant see the Xray been a heavy car even with STD size servos etc??

Post by gwesty on Oct 9, 2009 14:12:09 GMT
+1 les i still cant see what the extra costs are ? bodyshells are something that need replacing from time to time , as john says he runs a large servo , the esc are similar weight , so that leaves motor ,and lipos . |

Post by lesbaldry on Oct 9, 2009 14:15:25 GMT
Hey Pete your not spraying your shells with primer filler are you?? ;D
All joking apart its very easy to add an unwanted 10grms plus to a shell with too much paint.

Post by oldtimeracer on Oct 9, 2009 14:47:32 GMT
As I have said before. I can get the Cyclone to 1355 just by taking all the weights out and even with the Lipo fitted properly the balance is only slightly out. I am running the old Sphere speedo, standard receiver and servo etc and nothing else that is particularly lightweight. I am sure I could get down to 1350 without doing too much and without spending any money whatsoever.
It would appear that some others may not find this so easy.

My Mi4 will get down to 1380g just... I'm unsure if 30g will make a large difference on track - I might give it a go on Sunday if I get a chance.. see what a difference it makes in the car...

Ive just had a look on Demons site ref ESC weights .the blurb states a "stock spec" type speedo is 24 grms (with out wires??) and the GM 120 is 95 grms (with wires??) hmmm I dont think thats correct some how?? . I have weighed some motors tho,there can be as much a 15 grms between makes(same wind) |

Post by oldtimeracer on Oct 9, 2009 15:29:56 GMT
The Sphere TC is 45gms while the SPX is only 24.5.
There is obviously a difference in weights between different "kit".
The website says the GM 120 is 95gms without cables. Does not seem right somehow.

Why is everyone on about 1350 grams, do you know something I dont? I know there will be a discussion about a weight reduction at the AGM but as yet theres no official word on what it will be. Personally I hope it will be 1400 to 1450 but whatever it goes down to if you like your car heavier then race it like that. |

Post by Reuben on Oct 9, 2009 16:59:04 GMT
Yeh 1380 is about where i can get. mayb 1370 with my lighter 4000mah lipo (but as mentioned above the car is a little off balance). but i do need to trim all my wires and remove the fan from the stock spec.. lets see where that leaves me |

Custom sprayed Les so no idea. Personally I suspect it is the XRAY oil; it is so heavy it keeps forcing itself past the seals ;D

Seems like this is all about loosing "grams" everywhere.
Ok I was a bit of a non believer that it could be done but looking at all the posts on here I can see how it can be achieved!!!...so we are going to go on a diet!
1350g !!! the target

Problem over, no need to loose weight. It is official, there will not be be a T2 '010 this year. It's a T3 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Boy I cant wait for that ;D  ;D ;D ;D ;D ;D |
