Mclaren MP4-30 Honda

another possibility is that the upper a-arm actually controls 3 dof rather than the typical 2. The outboard end seems long enough longitudinally to plausibly contain 2 ball-joint connections to the corner instead of 1 like a conventional wishbone. This would result in the arm constraining 3 dof. The rear leg seems thick enough longitudinally to maybe support this arrangement (similar to the Merc front suspension lower wishbone).

There is a rule that says the suspension can't be over or under constrained, but it's not clear what that means in practice. If there were two ball joints on the outboard end of the upper a-arm, then the suspension would not in fact be over or under constrained.

It's fun to not know!

Least interesting possibility is that we are missing a link due to angle of pictures.

EDIT: the 6th dof is being held in place by Ron Dennis' sheer force of will!

Seems to me that the fault could just as easily be an improperly ground terminal. To interpret their trouble the way you have seems 'far fetched'. The conflation of your 'control boards' and a r.dennis quote is also misleading.

no the problem was already stated as being miscommunications between sensors and ecu's. either the sensors send wrong data, or the ecu reads it incorrectly, or there's a lack of sensor data, or the ecu reads it corretly but sends wrong commands which then causes the sensors to send correct data that the ecu will see as actually being wrong ect ect. electronics are a bitch. even on road cars. even bigger bitch is diagnostics when something fails, because you don't know what gives correct data ect. trust me i know.

fer, merc and ren all had the same problems last year. and yet all managed to race in melbourne where where the best car won, and not the best engine per se.

I've found these videos on youtube... The engine sounds cleaner than the last days...

They fixed the problems hopefully not at the expense of performance.

Mclaren honda 3 DAY TEST Sound PU now it's ok ?

A quote from the track:

Honda engine sounds good at full load, but very different from the rest in the transition from q rises and returns to accelerate.

Do they really want to say "different"? or do they mean "badly"?

Today it sounds more normal and the car is running more, it seems that the adjustements are working well.

not sure mate,the quote is google translated!

[ollandos]

the engine is ok today ..and on run very low pressure...but turbo must be starting higher

[Aaronque]

It sounded like harley davidson when off throttle

After seeing that Picture from the McLaren Rear End on the last page i must say i'm a little in Love.

Also that Picture shows really well how Skinny that Car is.

Last year ALL the engine sounds were very different during testing compared to how the cars sounded throughout the season.

I don't think engine sound is indicative of anything other than testing particularly of engine maps associated with the blending of ICE and electrical power. This time last the Merc was particularly tuneful creating a symphony of sounds.

Glad to see McLaren finally getting some meaningful lap's and mileage on the engine, this is after 2 day's pretty sure Red bull were still struggling at this point in the same test last season. Just show's the people who said McLaren were in trouble need to have more patience and a little faith.
