Ok with Calshot Practice just 15 days away - can any of you fine people give me some setup tips to stop me making my lovely purple car, a lovely purple cloud of dust/smoke??
I'm guessing high ride height.. and really hard springs?? is that about right?? what else??
Matt
;D ;D ;D

My calshot car was born last night is't a mix of Mi3 and Mi2 with some super stiff spings and down stops added to the shocks to stop the chassis rubbing on the floor.
I've got 6 deg castor blocks to give better high speed steering (not sure how necessary this is) At the moment iv still got 3deg rear toe in ( Les what do you run? as i'v killed rear tyres with this setup in years past) The drive train is super smooth with a spool up front (i ran a diff last year which was nice and safe, may have to revert back to this)

Rob I dial out as much rear toe as I can,6 deg castor works for me with slight front toe in for straight line stability,ride hight ,8 front 10 rear"to try and eliminate air time ;D",high lower roll centers with short as poss upper camber links (set parallel to lower wishbone if you can)...springs as hard as I can get with bump stops fitted to shock shafts,right hand side only...only needed in mod Spool in front Rob??...not for me chap,I found it wondered down the strait under hard throtle off the banking."allways correcting steering"...I try to avoid this at 70mph plus If this is any help...I was destroying 30plus shore tires running some rear toe a couple of years ago,but I think a lot of the damage was done not only by heat but by the side wall getting pinched by the rim under compression on the banking??...last year I got away with Sorex 36's and very little rear toe...its a shame foams dont allow the mods to plant the power off the banking...32's on inch up's and a hard insert may work well? If I remember correctly in practice Ian temp'ed my rear right tire at 80 deg C running toe in!! I believe Reuben is running calshot for the fist time in mod...a baptism of fire chap, good luck!! The best tip for new runners to Calshot ...dial out as much steering as you can with set up and steering lock with linkage's and run no more than 3mm left and right lock(even less in mod)...It sounds a silly figure?? trust me you will need only this amount or the car will be a mare to drive/change direction at silly speed!!

yes, so a 1 degree toe block at the back will be sufficient, what about shock angle? lay them flat for the minor adjustments or straighten them up.
how about droop? alot or a little?
finally speedo settings - probs more personal thing... max/min punch? max stick brake, no drag?

Shock angle is not critical..for what its worth I stand mine up As for droop a little chassis rise is worth it from your prefered ride hight....Calshots not as smooth as some may think!! Max punch and a little engine brake in mod to slow slightly into the banking...as for stick brake...if you do need it it will be too late "you have already crashed ;D...Driving the Drome at speed is probably the most mentaly demanding track you will ever race on.

So by 'as little as i can get away with' how much rear toe in do you run les?

Post by lesbaldry on Mar 9, 2009 15:45:21 GMT
So by 'as little as i can get away with' how much rear toe in do you run les? 0.5 to 1 deg(total)..I tried zero but got beter traction off the banking with a little toe in...and the car wondered slightly with zero..but we are talking "my old Losi"here yours may be different. What's your chosen power unit this year Rob?...I cant justify a new motor this year so Ill be sticking to my old favorite and another chassis "depends on practice"..the Losi's may be past its sell by date Matt ,Reubs what do you want to know "set up wise"..I've never ran a Cyclone round the drome but I would imagin the basisc's should be the same.

Apart from doing the old 13.5 class. I have decided this year to have a go at the 19t brushed. Anyone help with gearing? It will will be dropped into a T2007.
Thanks.

Trev Trev If I remember corectly 19t torquy motors were getting geared around 3.8 ish..Ian Newtons the best chap to ask he was fast last year in 19t brushed

Trev Hi Trev, We've recieved yours and Tom's entries. As goes gearing its abit of a try and see job, its possible to go really fast but not for the full four minutes at the motor will just over heat! I remember watching Mark Townsend leave the rest of the field for dead (with a 19T ) but then only to get overtaken in the very last laps of the race as the speed died off. 4mins is along time when your doing 10sec laps. Try and get over for the practice next monday to get some laps in.

All is not lost my old Losi rocket has been resurrected "super glue and carbon fiber" with some "minor" improvements Mondays testing will be with something new...might end up in tears though ;D

I dont have a 2.5 and my 4.5 will be in the tourer.... I wont be going as fast as you crazy people due to only a 4.5 - lucky just to get it round under 6 seconds?
Mini - just a well used 15t silver can thing that came with my sprint 2... works well in the buggy, lets see in the mini.

A 4.5 may surprise you Ryan Doherty gave me a hard time with one last year..its all about good set up to apply the power and a perfect ratio to carry the speed for 4 mins without thermaling or dumping. I think there is two ways "in mod" to drive the drome,gear the car low to carry flat out speed round the banking but the car will be slightly slower down the strait or gear it slightly higher for max speed down the strait and coast round the banking to save power drain(40% of the lap is spent on the banking)

Is anyone able to bring some spur and big pinions that will be for sale on practice night. I need smaller spur for 008 and larger pinions above 39 tooth on the pinion.

Trev Thats a shame Trev I have just sold my 008 and spares including an adaptor to take "odd" make and small spurs..but I may have somthing to sort you out..see you tonight! Ps..Calshot practice tonight should be very interesting..there will be a new very rapid "little" misile to be tested...good luck with your test run tonight Mick,I look forward to seeing it do Mach 2

Cheers Les. Tonight I want to test my 19turn and just tinker with the 008 gearing using a 13.5. I forgot all about the darn spur & pinion gear requirements. If I can get a smaller spur around 60 tooth for the 008 (48 pitch). I have adequate pinions, have to see. I will probably be the last to arrive as I have to wait for Tom to get home from college at 5pm and then hack down to Calshot through all the commuting traffic

I will probably be the last to arrive as I have to wait for Tom to get home from college at 5pm and then hack down to Calshot through all the commuting traffic Trev the prob with the spur/008 fitting of other make of spurs is their thickness,the black plastic screw recessed washer that sits behind the ley shaft pulley and spur gear needs to be thinned to half its width to allow the slightly thicker spurs..I found there was two choices,thin the original "rub it on sand paper" which can be a pain in the rear or make another out of fiber plate or some suitable thiner plastic washer....somthing to do while waiting for Tom? ...Trev Im just hopeing I have one in my pit box but dont count on it. Ps you will need 3 very slightly longer Button head screws too..the 008 is very awkward to mesh and get ratios in the 3's with 60 sized spurs, the small spurs gets in the way of the rear motor mount screw "blocks access" no holes to poke a driver and screw

les.
Thanks for the info, finding time waiting for Tom is a problem as I have plenty of work to do otherwise. See if I can get a hour in the workshop later on. I did think putting a smaller spur might be a problem as the 72 I have on is a pain to mesh, so a 60 would even worse. I suppose the alternative is to go bigger spur with a bigger pinion, with a 72 spur I am going to need a 40 pinion to get 3.02 FD. I think I have 39. Anybody one I could borrow for tonight?
