THanks and i cannot wait to run it! I am running the 40C SMC lipo
Most people just shave off about 2mm from the underside of the mount.

+1 just sand it down by hand don't use a dremel too messy

so if it tells you the force per wheel travel.

weight*lateral acceleration*cg height / track width

so reducing the track width increases weight transfer
Thanks.
Do you have a reference to the formulae, and how it is derived

Charlie, When you say spring tension you are talking about ride height correct?

Thanks for your feedback.TJ

okay small physics summary:
basically it is the reaction in the outside tire to the lateral acceleration on the mass at height.
not taking into account gravity only lateral acceleration we take the sum of the moments about the inside tire central contact point.
sumM_insidewheel=0=mass*lat_a*cg_height - Fouterwheel*trackwidth
so
Fdue to lateral G= mass*lat_a*cg_height/trackwidth
to get it into mass units do F/gravity

to get the total weight on the outside wheel you would start like this:
sumM_insidewheel=0=mass*lat_a*cg_height - Fouterwheel*trackwidth + mass*gravity*0.5wheelbase
and bring out the Fouterwheel again.

and finding the inside wheelload would be sumF_vertical=0=Foutside+Finside-mass*gravity
Finside=mass*gravity-Foutside

hope that makes it a bit clearer

to get these kind of things easier may i also advise either of these books
-competition car suspension by allan staniforth (simplified and easy to read)
-race car vehicle dynamics by milliken&milliken (more complicated but the best book though not in SI-units)
-fundamentals of vehicle dynamics by thomas gillespie (complete basics)

Default Cyclone TC :D

Hi,

Just got my cyclone TC world edition and I want to prepare it for a race on saturday. Could you please let me know what should I take into consideration when building the KIT? Should I do something different , is there any tip you can give me when building the car?

Also , I will use a 13.5 motor , and I want to gear it to 4 - 4,5 , could you please let me know what Spur/pinion will fit? Also will the 48p spur/pinion will fit , and if yes , what combination of spur/pinion will I have to have to gear it at 4 - 4,5.

Thanks

-fundamentals of vehicle dynamics by thomas gillespie (complete basics)
My basic issue is now resolved, that is, the derivation of :
-- Fdue to lateral G= mass*lat_a*cg_height/trackwidth

I also did some google searches to get a different perspective on things (some have diagrams which always helps).

I will look into your references as well.

All good bedtime reading.
Thanks

Hello man, you must look into GEARCHART.COM ... i did a calculation that shows your alternatives on the FDR you need, but you can go to gearchart.com and try another combinations :




cya !!!

46 pinion and 100 spur(64 pitch) that gives you 4.71 ratio and 42.68 rolloutgood combo for me

i thought the ratio for the cyclone WCE in the manual is 2.4375?
isn't it large pulley divided by small pulley?
39/16=2.4375

Cyclone TC came with 18T pulley.

I've heard rumors of a new kit--True??
Was gonna redo mine for this year but if there is a new kit in the works--
Parts are a pita to get and if I have to wait for parts I might spring for a new car if it's true.
