Why Aedynamics Are Important Even In Rc Cars

[Full Monty]

Cool stuff, I have just quit racing R/C after about 8 years of competition, I raced 1/10th scale electric Modified Touring cars.

Started out as just a weekend hobby, quickly turned serious. Travelling interstate for State and National meetings.

Its gets pretty pricey at the upper levels, but seriously great fun.

Go race at the brendale track and see how fast they go.

Elec is like watching paint dry though.

1/10 Nitro is the go or even more impressive 1/8 Scale, they are stupid fast and stupid grippy.

Will be in Brissy next year racing so am looking forward to one of australia best tracks.

Shop overseas for rc always...

LOL cant race mine, its too quick. that's the reason that you might think electric are slow. Even in modified you can only run 7.2 volts and a sensored brushless engine. Mine got 11.1 volts and a unsensored brushless engine, so it is past the limits and not allowed to race. Mine would easily keep up if not pass those nitro ones. but I have a problem I cant drive anyway.

The whole point of modified is skill not speed, and I kind of lack in the skill department.

Agree with Full Monty it can get expensive.

Sorry to hijack this but what about some pics and scale boats. My toy is just under a metre long, powered by modified whipper snipper motor (Homelite 30cc) Pics attached.

actually that statement is quite untrue...1/10 modified electric is usually faster than equivalent 1/10 nitro at every track we raced at...with speeds in excess of 80kmh on the straights.

Electric Tourers have lighter weight, lower c.o.g and instantaneous power and torque.

I think the attraction to the nitro cars is the noise, kinda like our knuckle dragging V8 loving friends...lol jk.

when Ive rocked up to nitro tracks and taken a few laps with a mixed field, they are always amazed at the lap speed..."but its got no exhaust mate"..lol

here is the brake down of costs of my tourer (BTW I was sponsered by a Brittish manufacturer, but these are the full retail shop prices here in oz.

Race Chassis = $600 - 800

Electronic Speed Controller= $350

Modified motor, brushed or brushless= $150

Transmitter and receiver Pro level= $500

Steering servo= $150

Battery pack 6 cell NIMH 4200mah= $100 (lipo not yet fully sanctioned for racing)

Consumables such as tires= $50 per set (compoetitive for 3-5 timed runs)

would often go through 2 sets of tires per meeting, many more at a state or national meet

Body shells about $25 plus painting.

When I was most competitive, I was ranked 3rd in the country in Modified Electric touring for the 2003 season, this required a fair bit of expense in travelling to various state meetings, and consistently finishing in the top 5.

I also won a free trip to Japan to represent Aus at the Tamiya World Championships in 03, all expenses paid with spending money....absolutely awesome, finished 6th overall, after some misfortune in the final race (taken out at the first corner, was placed 3rd outright going into the final race)

It got to the point where you could be racing club level go karting for the same money, so I decided to get out, some guys spend insane amounts of money to gain a competitive edge, with the top few drivers separated by just a couple of seconds after a 5 minute heat, tires, motors and batteries are crucial.
