DisarmingBaton5 Posted February 11, 2014 Share Posted February 11, 2014 I can have a car by Tuesday. Also, Driving in staging mode allows you to use RCS, only you need to use IJKLHN keys. Docking mode may be easier, though, because you can toggle RCS on/off. Link to comment Share on other sites More sharing options...
GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 I always use my IJKL keys for driving about. Docking mode or not ^ Link to comment Share on other sites More sharing options...
Blaze 9X Posted February 11, 2014 Share Posted February 11, 2014 Okay this is my second version. This is the one that I am using. Weighs EXACTLY 0.9 Tons with an empty RCS tank.Javascript is disabled. View full album Link to comment Share on other sites More sharing options...
GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 It will be interesting to see how light cars like yours compare against heavier ones. Acceleration might be better but then with more weight comes more traction. Got any performance teasers? Link to comment Share on other sites More sharing options...

Acceleration might be better but then with more weight comes more traction. Got any performance teasers?Thus far: Slow to accelerate, reasonable top speed (I have not reached it yet, it accelerates VERY slowly), very quick to turn, stable. (I had difficulty rolling it for crash testing)The car accelerates at an acceptable rate with RCS. Link to comment Share on other sites More sharing options...
GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 I have reached a similar conclusion. Looks like your design made me rethink my own solution. I can give you a tip - put small nose cones on that RCS fuel tank to ensure lowest possible drag. That should help you out a little.It does look like lowering your weight helps out immensely with performance of the vehicle - I thought increased weight might improve traction but since we have wings for downforce, all weight is, is an inconvenience. My main issue now is to try and eradicate all unnecessary components whilst keeping the driver safe from any kind of impact. That is proving challenging to say the least.

DisarmingBaton5 Posted February 11, 2014 Share Posted February 11, 2014 (edited) BRT-C01Javascript is disabled. View full albumMy initial entry, it will probably change a bit by the first race. This will be updated if it does change.EDIT: After experimenting with decreased mass (0.6t less), it appears that increased mass does help traction and thus handling. However, the speed/acceleration benefit from a lighter car seems to outweigh that.EDIT2: Only in Kerbal Space Program could a lighter car be less maneuverable.

GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 (edited) Everything is relative. The angling on your control surfaces prior to the race is very important. Too much angle will cause excess drag instead of providing negative lift to keep your car on the ground. At lower speeds you might want more angle, but then I am not so sure about the overall effect of that since you would greatly increase potential high speed drag.What I found was that a very low angle on my control surfaces seems to do the trick. As for maneuverability, length of the vehicle is key here. Your car, although looking great, is also very long. I say ''very long'' - it's of normal length, but for the purpose of the race, it's on the longer end of the scale. You could compensate by slightly shortening your wheelbase, without having to alter your chassis.EDIT:Alteration to vehicle submission.Recent submissions have prompted a re-design of my own vehicle. I have come to the realisation that 1.9 tonnes is not an appropriate weight for a racing car. Here is the resulting design I will be using this season:BOXX-CART UT-i7 SPORTDry weight: 915 kg (that's right, I shaved off 815 kg off the total weight)Total weight: 1115 kgThe basic chassis of the car remains the same. However, the structure of the space frame has been altered. Beams have been replaced with struts and molded into a nicer shape. Heavy reactors were removed and replaced with an altogether new and radical solution - photovoltaic panels. This allows me to keep the weight down whilst allowing for full power to all wheels, even in sub-optimal lighting. Readjusted spoilers and added extra crumple zones for better protection of the driver.Centre of gravity is so low that I have trouble flipping this car in corners. when it DOES flip, the roll cage begins to peel off bit by bit, absorbing impacts and protecting the driver from any nasty collisions. Wheels can snap off as a result, however, you wouldn't honestly hope for a good lap time after a crash - car can be rebuilt, but there is only 1 randomly generated Camrod Kerman. And I intend to keep him for a long time to come ^^ In effect, this car has working crumple zones.Changes have also brought the costs down to $52k, which is nice.Pics:Speed run:So that is that. I simply can't stop developing it now but I will have to force myself to leave it as it is xD Edited February 11, 2014 by GROOV3ST3R Link to comment Share on other sites More sharing options...
NQMT Posted February 11, 2014 Author Share Posted February 11, 2014 I'm thinking of doing a small redesign. Will keep you updated. Link to comment Share on other sites More sharing options...
DisarmingBaton5 Posted February 11, 2014 Share Posted February 11, 2014 ~megasnip~This gave me an idea. [insert evil laugh here]Those photovoltaics are nice and light, but do they work in the dark? You may remember that there was a night race last time. Nice car, anyway. It looks great. Link to comment Share on other sites More sharing options...
GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 Thanks ^^Megasnip lol.You are right to be concerned, the craft will run out of electricity in the dark faster than you can say ''Jebediah''. Kyrian said that I won't need the lights on my car - hence why I am assuming a daytime GP. Plan is to run the car in optimal conditions - if I did that, I might be able to shave even more weight off anyway.I like your design too, everyone has had their own idea ^^ And now we are competing and racing to develop an even better vehicle than before. This season will be a fun filled one ^^ Link to comment Share on other sites More sharing options...
brobel Posted February 11, 2014 Share Posted February 11, 2014 Working on my Rover weighs about 2passed all test except roll test kinda. only need to improve roll cage as when it flips he rolls out of his seatwill have a finished version tomorow Link to comment Share on other sites More sharing options...
Frafor Posted February 11, 2014 Share Posted February 11, 2014 Is amazing that every car is different to the others.This gave me some ideas. Looks like I will change more than just the wing's angle. Link to comment Share on other sites More sharing options...
randomness5555 Posted February 11, 2014 Share Posted February 11, 2014 (edited) Yeh, I think I might try to lighten mine. It does seem WAY to heavy ATM. I'll repost once done, and DW, i'll remember the rules this time XD Edited February 11, 2014 by randomness5555 Link to comment Share on other sites More sharing options...
randomness5555 Posted February 11, 2014 Share Posted February 11, 2014 Okay, the final re-design. It weighs EXACTLY 1.718 tons full (as the RCS is only 0.375 full it's definately fine for weight, and the lightening has worked.)It's now the BWRC T1 G1 M3 (or the Blue Witch Racing Company Type One Generation One Mark Three)No large wing foul ups for me this time!

NQMT Posted February 11, 2014 Author Share Posted February 11, 2014 I did say 'small' redesign, right?Scratch that. You'll see soon. My aim is >0.5kn of drag for the whole car, and a top speed of 25+ on engine power alone. Link to comment Share on other sites More sharing options...
GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 (edited) RCS fuel in the FL10 tank weighs 200kg.Other than that,I don't think it's actually possible to reach 25m/s on power alone. However, with a light and aerodynamic vehicle, you can reach 50+ on RCS. This needs more testing.EDIT: I will repost my updated craft in the original craft post.

Frafor Posted February 11, 2014 Share Posted February 11, 2014 I made some changes to the car. First, as almost every one of us did, I changed the 4 RTGs for 7 solar panels. The car is made to run with day light, so if there is a night race I will have to place some batteries. Then, I replaced the heavy I-beams from the roll cage with cubic struts to reduce drag and weight. The car now weights 1.04tn and its name changed to "SP09".Also, when I was testing I made something like a diffuser that made the Drag coefficient went from 0.750 to 0.500. I don't really know how this would affect the performance but it seems to be pretty efficient. Link to comment Share on other sites More sharing options...
CaptainGiblets Posted February 11, 2014 Share Posted February 11, 2014 With all of these new cars and faster ones, I need a major redesign Link to comment Share on other sites More sharing options...
NQMT Posted February 11, 2014 Author Share Posted February 11, 2014 Frafor, the rules state that a maximum of 2 small surfaces be used on the rear of the car. For now, that diffuser is illegal, but next season I'll change it to 3 or 4.I'll post the Season 2 rules and regs after race 3 or 4 to give everyone time to develop.

GROOV3ST3R Posted February 11, 2014 Share Posted February 11, 2014 Well, it would certainly pose new challenges, such as transport, accommodation for drivers, garages, what to do in case you wreck your cars etc. I mean, you can't fix a vehicle in KSP.Why are these things an issue? Well, you wouldn't want to base a KSP rally around the Space Center alone, would you? There are much nicer places to drive on. However, not many places which are genuine tracks to navigate. You'd have to mark out your own track or use a predetermined savegame with locations and tracks already laid out.It might happen in the future, but for now, we will focus on track racing rather than rallying.

NQMT Posted February 11, 2014 Author Share Posted February 11, 2014 (edited) Well said, GROOV3ST3R.No chance of being on the Mun, however. I'm too lazy to get there.For a rally, I'd be thinking of point-to-point instead of a predetermined track.Also, Frafor, how do you measure the drag coefficient? I get no readings from FAR from the rover itself. Does it show up in the SPH?EDIT: 100 posts on this thread! Sweet! Edited February 11, 2014 by Kyrian Yay!
