Fuel Burn Rate Of The Kruzza?

[Greg Mitchell]

Morning Sam,Elise and the kids say Hi to you and your family.These are the figures I got back from Larry.The Golden burns about 9 gallons of fuel/hour.The Turbo Golden burns about 12 gallons/hour.These fuel burns could be reduced with the installation of the IvoProp inflight adjustable constant speed prop unit which costs about $2,500 USD more.This would decrease the fuel burn on a trip by about 25%.Looking forward to catching up, will ring you for details on Temora and Avalon.Cheers,Mitch.

Holy Hell those fuel burns are pretty massive,

Well since i got time on my hands, i got some fuel burn rates from my new Xenon i got last week.From NSW to YCHT some 1250nm average speed ISA about 65-70kts with fuel load ie. full fuel with another 70lts sitting on pass seat the average over 7 hrs was about 16.5lt per hr, cooler the climate the better the rate, up home where it was nearly 40* already it was probably closer to 18lts but still good rate and concidering it will still climb at about 1400" per minute pretty good for a pony huh(125hp), well im impressed anyway.

Sounds amazing bones.

The Golden Butterfly and the Turbo Golden were designed specifically to train new pilots in the use of the G Force Landing Gear and to be CLT gyroplanes.In the USA a lot of blokes are over 100 kgs, many are 240 - 260 lbs. Australia is not that far behind the yanks in this department.I saw folk in the USA at Mentone being turned away from a ride in a couple of makes of two place gyros, because they were just to big.The Golden with an average weight pilot and full fuel can carry a very big bloke.The Turbo Golden can be operated with a very large pilot and very large passenger. I dont know of any other craft that can carry a similar load with 15 gallons minimum and up to 30 gallons with upgrades. Performance Features

Well thats all fine and dandy Mitch but when people take the fact they are fat pr*cks to heart and want to do somethng about it, is their choice, but in the mean time, the machine i was flying the other day i took another user on the forum here, who is 120kg, and im about 95kg, and we were still getting 650" per minute, with only 5300rpm, thats not too bad either, keeping in mind this is with only 125hp, also i taught another guy to fly, who was about 130kg, we were still getting about 400" per minute, at about 35-40, at 1000" asl, didnt work out the density alt.i not interested in saying the machines i sell are better than another, cause at the end of the day it cost me to sell them, but if someone wants one, i will organise it. If the Kuza guys would just do a machine with the 914, and get it light, i would sell them, as of late i have sold 3 machines because people dont want to fly on Subs, it is that simple, and there is no other real choice yet.

Ah think of Shakesphere,maybe Macbeth,the tension is building,a hissy fit will ensure then an all out brawl.

YES both are set for 5200 RPM Full Noise.Thanks Sam. Am I to understand then that the VVT is running more prop pitch? I take it the redrive ratios are the same. Aussie Paul.

Apparently the variable cam and double cam versions are producing better fuel burn results.I have no Bone to Pick or interest in a pissing contest, only relating info from the manufacturer to a prospective client, the info itself caused me to take a harder look at other engines currently used in gyros for comparative purposes.Kruzza is what $40 K cheaper than the Xenon? The Golden with variable pitch prop is $42,500 USD or around $45,000-$46,000 AUD, whats that about $40 K less than the Kruzza. 190 HP giving a 6.75 gallons per hr fuel burn, so whats that about 26-28 litres per hr ?There seem to be a lot of home built subs about here in OZ and in the USA.Anyway, I have the information I was seeking....the Kruzza sounds like it has a lot going for it and we all know how popular the Xenon has become to those able to afford one.

Hi PaulNot sure of prop pitch, but neverless its producing more power at same revs, and is able to fly at lower revs with same weights. I definatly now I wont one next ;DSamL...........

watch out for fuel burn quoted for certain european tandem machines i hear they say 15 litres at eighty knots two up (possibly 23litres at eighty knots one up) ;D

Thanks.Mitch
