RC Driving Style
Rite am tempted to lengthen my rs4 about 2" using a custom carbon fibre chassis. putting in a large engine possible a .21 or tuned .15 or twin .15's or 4stroke. making a custom "caterham" style body out of aluminium sheet metal. black wheels with slicks etc. What does everyone think....? Custom intake cooler as my dad makes pipes and fittings that would flow water or air, put a custom box at the front of the car acting as a rad and use the flowing cold air to cool circulating air or water. Disk brakes on the front and an exhaust running down the side of the car with custom fuel tank. opinions...
 
sounds like a super fun project man. I ofton have wondered if anyone has ever attempted to put twin engines in an on-road. It would certainly be one of a kind I'm sure. I think a .21 would be ideal though for a project like that. On-roads are so much lighter as compared to MT's and stuff I don't think a 4 stroker would be necessary. Everything else sounds pretty interesting... kinda wondering how your gonna get disc brakes on that car. I'm not really familiar with the rs4 but I think it's a 1/10 scale aint' it? I've never seen 1:1 style disc brakes for cars that small. I know they exist for 1/5s and 1/4s. A word on custom fuel tanks... it you're willing to give up the ability to see how much fuel you have make it out of aluminum. I tried making a custom tank out of plastic and it's not easy. It's possible yes but in my opinion not worth the effort. I'm planning (4) 2oz. tanks for my twin .26 tmaxx. All in all I say go for it and keep us posted.
 
I'm still unsure whether to do it or give rc up. If I did, the fuel tank would be aluminium. I have seen 2 cars with twin engines a .15's and .21's with superchargers. The reason for the 4stroke would be for the noise and the torque all low down and more oppurtunity or sc/tc or nitrous. Thats where the fun would be. As for brakes I havent realy thought about them but it would be dificult. Wheels would need to be largened to fit any descent sized disks in there and the caliper would just be a clamp running of a servo. Probably more trouble than its worth!

My ideal project would be a 4stroke with a turbo :idea: but it would be hard work, making a turbo small enough that could creats a descent ammount of psi would be dificult 1:1 turbos spin at a few thousand rpm so making a scaled down version would be a pain in the arse, imagine how small the bearings would be :hammer: .
 
dont make a CF chassis they hold the heat. aluminum is used because it cools better.
 
carbon fibre will be light and strong aswell as looking good, A mate is making me one 2.5mm thick and a lengthened version of the rs4 for $75. So first stage is to get that mount the suspension on and get custom coilovers, I have a good idea how to make them myself. Then I'll post pics and look at which engine/engines to get and a solution to a driveshaft that will fit.

Opinions.....
 
uyou want a big block and work ehh?? use the fantom fr27 engine LOL
 
Right.. Now getting the cf cheaper than expected, going to send the guy my design tomorow. I'm now thinking of getting the 0s-fs26-cx, 4stroke power :boxing: !!!then a sc should work wanders! What dya think. Although not sure if it's worth spending $300+ on an rs4, if I do it there'll be lots of pictures and movies :)

Um, turbos on reals trucks spin damn near 100K RPMs. Just trying to point out another problem w/ making a super smalll turbo. But that's just my :2cents:
 
according to RB Inovations website, they will make their supercharger fit any engine if you contact them.. heh, it might actually be worth a shot if you're gonna use a 4 stroker
 
rb innovations supercharger is trash can worthy. theres a new turbo on the markey that uses no belts and runs off of your servos i can't remember the name i will have to look but maybe it will work.

ok, so I'm definately not the most knowledgable r/cer but that doesn't even make any sense, I mean the no belts part yeah... but just as questioned above.... how's it gonna run off a servo? That would be like hookin it up to a battery pack. the whole point of blowers in general is to create more HP without the added weight of say... more cylinders or a larger displacement. To use a seperate source of power to move the blower is just mindless. i don't mean to raz you too much but it just doesn't seem right... at least the way you put.. typo maybe?
