Aixro XR50 Wankel Engine Kart using GoPro Video Camera

[perryinjax]

I wanted to see the wankel engine :-( Where did you get one and what does it look like on the cart? Does it perform well? Reliable? is this common? I have never seen a wankel engine up close. COol man :-)

[alexvangeen]

i'm hoping to have a go in one of thoes soon maybe wilton mill. that track is daytona MK i love that place only been round it in a pro kart though but to put in to perspective a recpectable time round that track in one of their karts is 1.10's looks like you were doing 54's!! thats stupid!!

what was the thing you were adjusting?

[TheRealFobican]

2:30 Is that a gearshaft you´re using?

[JasonMann8]

@TheRealFobican adjusting brakes

[bolo988]

this cart has 1 gear?

[sigus96]

See this: youtube.com/watch?v=ZztMwgBLhf­o

[sergiogon]

And what about reliability of this?

[baja5b889]

is the intrepid a stiff kart or is it relly fexible like a tony kart

[BlkFlagMotorsports]

good job positioning the camera. The problem I had was getting it setup so its not pointing 5ft ahead.

[subeefan]

intrepid chassis?

[andersonvik]

Where is the track, Daytona Florida?

I have a movie of me driving gokart with a gopro cam, in Bergen, Norway.

[lukewill783]

@andersonvik no, its in milton keynes, england

[TheCrashBrothers]

i kicked this engine's ass with my biland sa 250 (tuned-32 PS)

[xr50fast]

@TheCrashBrothers Well done; give yourself another pat on the back. Now what does this "comparison" prove? I presume it was scientific with drivers of similar ability, of the same weight, with the same tires, same tire wear and both with correct gearing.

One recommendation, though: Don't ever try an Aixro kart. You'd be amazed how your Biland feels afterwards.

[lukewill783]

@xr50fast nice one :)

[ApexSlayer13]

My teammate has one of those old Wankel engines in his garage, they are very cool. Hopefully we can get it running someday.

[boomer649]

its basiccly a stroke engine...

a 2 stroke engine has alot of top end power(more speed at high rpms)

4 stroke has more power at low rpms

this kart has power at top and bottom

[SpecPRDkarter]

It's a rotary engine wankel is the guy who designed it. It's a 4 stroke engine with basically a rotating triangle. One side is for intake, one for compression/combustion, and a third for exhaust. Rotary runs a shitload of rpm but the fuel efficiency is shit.

[varkow]

its not 4stroke you said

1Intake

2compression/combustion

3expansion/ exhaust

its a 3 cycle engine it makes 3 sparks to spin crankshaft twice

wankel engines are so efficient as 2 stroke

crazy high rpm with lots of power

and insane torque also

[SpecPRDkarter]

Well 3 or 4 depending on how you look at it. It combines compression and combustion. Yeah they make a lot of torque that's why they can run such small sprockets in the back.

[superfunnyman123]

dang! cool video!

[rhgotor]

WOW

[3Slipknot88]

what was he adjusting

[w4speed]

brake balance

[konode1980]

He adjusted the brake bias, because of too much oversteer under braking.

[3Slipknot88]

im a nascar guy is understeering where you back slides or does your car not what to turn

[pokrmastr29]

Understeering is when the car doesn't want to turn aka a poor handling car.

[SpecPRDkarter]

Or AKA you're driving in the rain =P

[pokrmastr29]

Hahah thats definitely true. Slicks and a wet track don't seem to work very well together

[stride99]

when your car doesnt want to turn

[standaway1]

Fool, have you ever studied steering geometry? Understeer is when you turn into a corner and the vehicle wants to go foward rather than turn and sledges into the corner, OVERSTEER is when the back slides out through corners. We use oversteer in karting.

[3Slipknot88]

dude. im from nascar. i have never raced either. just a huge fan.

[dillonbf]

Why do these sound like 2 strokes? D: The XR50 is a 4 stroke isn't it?

[TKDWolf]

It's really neither, for each full rotation of the rotor it makes power three times.

[stride99]

no its a wankel-engine. it has nothing to do with a 2 stroke or 4 stroke engine...

[DickWheels]

It's actually pretty similar to a 2 stroke and not so much a 4 stroke. IDK abot these but the mazda's have oil injection for better lube hense burn oil and they have ports instead of cams and intake valves. Their power curves are much more 2 stroke then 4 stroke. long live the wankel

[JGMagoo]

Does the Aixro have any compresion braking to speak of? Is it hard on brakes? I can see an advantage to NOT having too much compression braking as it tends to upset the balance on shifter karts coming into a corner.

[RACEDATAdotorg]

It isn't my kart no, I just jumped in for a go. You're right, it didn't have the perfect gearing on but also be aware that this track is VERY tight. It was originally built just for corporate and hire events and is too small and tight for a fast race event really. Still, it's a very enjoyable circuit to drive...

[crv26]

@RACEDATAdotorg i heard these thing were faster than shifters (125), verdict?

[connell256]

bottom end looks and sounds like its dieing in this kart, i tested a aixro xr50 and it didnt seem like that atol on the track i was on, it was sounding like it wants to go 24/7,

4:02 for example, it seems, like its flooded. This your kart whats problem or the track?

[Frapancho]

please tell me if you edited this video with some edition program or something like that, and what archive is it? AVI? etc?...thank a lot!

[NapalmCandy]

You can cut videos with VirtualDub, it is free and can to save in AVI with original compresion

[skyshiptrooper]

That freakin' thing is insane!!!.........

[bmonitg4b]

could you tell me what engin is it?

[Broddan81]

WANKEL!!

[connell256]

aixro xr50

[bmonitg4b]

ooh by the way can you tell me what camera do you use?

[RACEDATAdotorg]

The camera is called a GoPro HERO and it is the WIDE angle version with a 170degree view. Then on this video, the camera is on the suction mount which comes with the motorsport kit

[bmonitg4b]

thanks i bought this comera right now :D

[bmonitg4b]

hm, i have front hand brake so i dont have such a problem. but my friend is driving with ICC and he told me that brake balance set up is very hard to find.

[jasonzbell]

What camera setup are you using? If you look at my profile, you can see my helmet camera setup, but your field of view looks much better.

[RACEDATAdotorg]

Replied to your other comment Jason. Your video from Infineon is very good but as you say, the wide angle lens makes a big difference. On the cadet karts, the camera is mounted half way down the nassau panel but still manages to put their feet in view.

[Dustin42076]

@jasonzbell its called FISH eye view

[bmonitg4b]

its intrepid 09?

[RACEDATAdotorg]

Yes I think so, it wasn't my kart. Chassis felt good though, it was just the brakes. At first the front brakes wouldn't stop with any power but then suddenly lock. I think with some more time adjusting it they'd work well.
