The BMW engined aircraft stuff.

[Litespeed]

Following from the Viking Thread we started talking about BMW engines again- I should say I butted in with them.............

 

So I figured it best to start a new thread for all things BMW engined that can relate to aviation. So it can include any BMW motor but as long as it can be aircraft powering- V12's included but I am mainly thinking the motorcycle twins and possibly the 4 and 6 cylinder bike engines. Essentially engines that could relate to RAA aircraft or even experimental light aircraft.

 

Anything is basically welcome vids, pics, opinions, designs, outrageous ideas are very welcome. As long as it relates a BMW powerplant and aircraft you will be sweet.

 

Naturally practical applications will also be happily digested.

Here are some vids of BMW twin conversions.

 

Note how small some are packaged and others just spread out to fill space. Some are much nicer than others.https://www.youtube.com/watch?v=5uqDwSDfZuohttps://www.youtube.com/watch?v=Ux83iZag5Y0

What was that?

 

Oh- you want a real aircraft. None of that modern computer crap, a real machine of metal, cloth and a red blooded pilot.

 

 

Yumm

 

Needs a louder exhaust but sounds great, big prop, redrive and not a Vw or rotax. A more grunty sound.

 

That is a late model 70's-90's r100 series engine 970cc old school aircooled with oil cooler and electronic ignition but can be points for the absolute hard core luddites. Carbs are bings and simple with CV diaphrams.

 

Normal power for this type is 70hp max and a easy 60 cruise hp for long distance.

And now with some shiny stuff:drool:

more of the old school motor short vid sounds like no fuel bar the float bowls- but nice.

 

 

[Litespeed]

And here is a R 1100 motor- so late gen injected oil/air cooled 85hp at 6, 800 rpm and 78kg as a package.

A R1100 motor in Rusia on a trike; nice install and note how well it just sits at exactly the set 3,900 rpm. Smooth.https://www.youtube.com/watch?v=whSTUQgvj04

I am hard of hearing but thought someone said- where is the real motors for real hp and speed, Not that grandpa grey hair stuff............

 

Keep your shirt on whippersnappers...........

 

 

This would be even better with a turbo or small supercharger to drop the revs and boost power.

 

Sure looks damn sexy in that sultry carbon

 

Cruise is 173 mph and it only weighs ................704 lbs empty .....................................................................................................................................................

 

I do think It could do with more grunt though- so the BMW 1600 cc 6 cylinder with turbo and intercoolers with 250-300 hp should suffice at much nicer revs and smooths as you like.

I can buy the Chinese made Boxer engines still here brand new, flat head(!) or OHV 750cc, 35 or 45 hp, smokin'!

 

Damn I wish they were 900.

 

 

 

[Litespeed]

My bro has one of these engines in his chinese copy of a Russian copy of a WW2 BMW it is a Chiang ?

 

I wish they actually had 45hp, the better version is more like 32hp on a really really good day.

 

But his does have reverse gear which can be fun, was designed for a sidecar.

 

The brakes are best described as a optimists folly- big drums and better to carry a anchor to thrown out.

 

Top speed is about 100kmh but at least it sounds mean enough to get a clear road- the traffic parts for you.

 

Before you think about it Bex...............no it would not be a good motor for a aircraft.

Before you think about it Bex...............no it would not be a good motor for a aircraft.

I meant I wished they were the later R90 series.

 

 

[Litespeed]

Yep the later /7 r series motors are great.

 

Mine was a r100cs, it was a factory custom picked up from the factory itself. Basically a R100rs motor with added light flywheel, wire wheels, 40mm Delorto pumpers, and bigger forks, luftmiester triple clamp and beautiful handstriped paintwork.

 

It was a absolute ripper and scared many a Ducati and Guzzi.

 

Unfortunately these models now are very collectable and all the rage for cafe racers- BMW is now one of the biggest brands for modded old machines. As such prices are ridiculous- it is easy to pay $8,000 for one that needs lots of work and was only $1,000 a few years ago as a box of bits.

 

Bloody BMW- how dare they become cool.

 

Must form hunting parties for Hipsters and free the BMW's from the tryanny of stupid beards and earings.
