IS THE GUIMBAL CABRI G2 UNDERPOWERED

[@stucarpenter1198]

you dont need excuses why your not doing your filming, as long as you are still churning them out..keep up the good work..

[@grahamlwilson]

Try flying the G2 in Australia in summer. 2 adults and 30°C and we can only put 90 minutes of fuel onboard.

[@flyingmonkey3315]

I'm just happy that you do produce videos. They're all great too! No need for justification here

[@GaryLaaks1]

It's a lovely looking machine. Slap on a GT2871 turbo and run E85 fuel. That will double the power LOL. You will also run a good chance of wrecking it. Love your Vids.

[@TheRailroaddan]

Thanks, I have heard they are under powered for max power take offs, but it doesn't seem that way in the video thanks again.

[@paulgraves5189]

I really enjoyed this video. I am going to look into taking a flight in this helicopter. Thanks for providing it

[@greggmoon6389]

Some great info. I flew a Hughes 269 no governor at sea level. Obviously no problems. I really like the cabri g2. A little pricey for me. Keep up the good work.

[@russella7263]

Looking at the smoke on the other side of the valley, I think the reason your power check seemed to over estimate the power margin available was due to the wind blowing upslope on your side of the valley and giving you some lift.

[@chrismaines1285]

Love the look of the new Cabri

[@stephenrobertson2901]

Every aircraft is power limited. Living in Johannesburg, South Africa, where my average elevation is around 5500ft, I understand it all too well. When you then start getting towards 8500ft density altitude in summer, you begin to really appreciate your aircraft's performance. Flying the EC120 here, an aircraft recognised world wide for "not having enough power", I simply have to laugh. It is all about application and understanding of the machine you operate. When pilots then start to talk about "running out of power" on an approach, I wonder why they took the task in that aircraft in the first place? You can't "run out of power" - that power was never there for you in those conditions.

[@stefansmuts8882]

Nicely put Stephen!

[@FritzWeinrebe]

Do you lean the mixture on the G2 for high altitudes (like JHB's 5500') before tak-off or is it one of those helicopters that fly with full rich mixture all the time?

[@rigilchrist]

That was very interesting, thanks. I have flown the Enstrom F28A; R22, R44, H369 and B206. The Enstrom is more power-restricted than the Cabri, I think. Happy Easter!

[@naughtyUphillboy]

NEW TURBO CHARGED ENSTROMS are not power restricted.......old ones yes.......

[@rigilchrist]

@@naughtyUphillboy That's right - I was talking about the F28A. I have 400hrs in the F280C, which has a turbo. Those engines rarely make TBO, unfortunately.

[@naughtyUphillboy]

@@rigilchrist yes, engine is turbo is an addition, putting mechanical and thermal stress on the engine....

[@chriseaves9762]

An A model Enstrom... yeah. That’s not a valid comparison. An F model (any Enstrom since the 70s?) is way more capable than a Cabri power-wise.

[@TimToussaint]

Mischa, there has never been a Cabri engine upgrade, nor has the engine "been chipped". It is also not a matter of opinion whether the Cabri is underpowered, but simply a matter of mission. It has always been the same 180 bhp Lycoming engine. The only thing that was changed is the gearbox rating; it was increased from initially 145 bhp to now 160 bhp (for take-off only). As the power of any naturally aspirated engine deteriorates with increasing altitude, this Lycoming engine from about 3,800 feet density altitude outputs 145 bhp or less. I you are operating at 3,800 ft DA or above, you won't be able to make use of the increased gearbox rating, as you are now power limited, not torque limited anymore. The only thing that got a software upgrade is the multifunction display, to show to the pilot the new gearbox limit. Missions (that you have shown in your video) that work OK at low altitude, will simply not work at all at higher altitude. The only way to address this Cabri shortcoming is to put in a bigger engine, while keeping the usable (allowed) power the same. Like Robinson Helicopters did it for the R44 upgrade from Raven I to the Raven II. If Guimbal had indeed upgraded the engine (say from 180 bhp nominal power to 200 bhp), while keeping the gearbox limits the same, then the 200 bhp engine would still be able to output 145 bhp up to higher density altitudes. It made a big difference in the R44 Raven II.

[@PilotYellow]

Tim Parter thank you for your detailed explanation. I hope everyone gets a chance to read this. It was well stated. I was essentially saying the same thing but not explained as clearly. I guess I was just trying to simplify it but your explanation would have been great to mention. However. That being said. The allowance of extra transmission torque at lower altitudes is in opinion what has made all the difference for the Cabri. I never feel a major lack in power now at lower altitudes.

[@bydandpilot343]

Even better, add a Turbo. If it was turbo normalised, you could keep the power; linear at say 150hp up to an altitude beyond almost anyone’s requirement. ;)

[@dougplaza7961]

Misha, thank you for yet another great video! I see others have mentioned it, but as a fixed wing pilot with only about a hour and a half in in a R22 (coincidentally where you picked up the R66), I was curious about the density altitude performance effect on rotorcraft in general. It is almost always above ISA in FL.

[@bernie2108]

Great series of videos, and wonder how they got Billy Christal to 'star' in them.

[@Kondratko]

That additional 10% required to hover in that confined landing was most likely due to the helicopter still being in ETL, resultant from the 25kts airspeed and the wind coming over the mountain.

[@mikesperrey]

I was honestly just wondering if they are underpowered when this video aired - spooky! Great videos: keep em coming!

[@chrismaines1285]

Do a cost video please on the Cabri and all options.

[@jcoghill2]

Is the G2 really that quiet in the cabin or do you have noise cancellation on?

[@jason1440]

Do you think a summer time vertical take off on that ridge at 4000 would have taken max power, especially if there was a minimal updraft or head wind? Was thinking thin warmer air.

[@rossbanner353]

Great job, super enjoyable.

[@chrisleavens2576]

It certainly seems like it has enough power. I’m curious how it compares to a R44 Raven 11 with 4 people 2 guy 2 girls and full fuel. So with in 50ld of Maximus take off weight? Thx

[@ChrisTaylor-fs9di]

Mischa do you think the Cabri G2 would work well here in Colorado? We are roughly 6000 asl. The schools in Denver use R22's. I spoke with Sam earlier today. I love your KZbin videos.

[@andreashutterer4740]

Just out of interest: What would you do in case of a sudden engine failure in such a steep and mountainous terrain? I understand the concept of autorotation, but, in this scenario, where would you land?

[@georgehofgren6123]

They probably keep a flat, ground area in view in case of power failure. The higher they are, the more rotor speed they can develop on the way down to use to land. Typically, they land in going-forward manner... so i think they need more of a mini landing strip, not sure. Hopefully he answers the questions 💁‍♂️

[@bobob427]

Is Sam setting up to be the new instructor at B C helicopters, that would be nice.

[@ellonysman]

murf I was thinking the same thing!🤔

[@shannonrose2170]

I want one! Might just go test fly one of the helis

[@goncalolemos5932]

Didn t you put the luggage stuff on weight&balance?....

[@ellonysman]

Say, Mischa...are jobs doing pipeline inspections mostly done by fixed wing or do they sometimes use heli?

[@charliemarren8724]

Oil field will use both, Rick! Great introduction work for a low time pilot.

[@actionrjackson]

I never felt the Cabri was underpowered. I went up with Mischa shortly after they got GELP and we had a lot of fun. I don't have anything else to compare it to however but as a trainer I wouldn't expect it to be lifting heavy equipment

[@robinbol4535]

Can’t you fill it up to 170 liters?

[@RogerODonnellTV99Xoutof10]

Yes full capacity is 170 liters

[@goapebilly]

Interesting video, never flown a Cabri, mostly r22 and can tell u ,which im sure they are very under powered, with 2 average people u cant fill up both tanks for w/b . im going about 175 a person. Max take offs are near impossible w/out a decent wind and riding at max power whole time. My experences with around 3/4s full fuel still not enough power . Hopefully I will get to fly a cabri one day ,and can really compare. So I believe with ur experience flying numerous different aircraft ,u would know which has least amount of power

[@dronemotioncom]

I fly 22s as well and clearly it's under powered... No margin for error, especially with that low inertia rotor system.

[@null2470]

Can you turbo it?

[@helicopterdriver]

Beautiful helicopter. I've flown a lot in the Hughes series and love them all, my favorite is the B Model 269. A few thousand hours in the C model 269 (Hughes and Schwezser) was alot of fun, but the plain old B model was a blast to fly. Such cool little machine. I taught a few people to fly in the B Model, so maybe I'm biased. Love the Cabri. What's up with the helmets? R ya'll scared.... :D

[@benb1079]

I would be interested in how the G2 compares to a R22. I think most people these days are flying R22s for training and that would be a more useful reference than the 300.

[@agcopta9633]

I agree the G2 are the better machine and R22 wasnt ment as trainer but they are a very forgiving trainer unless of course u do numb shit. As the say if u start in a 22 you learn to manage power well and generally can fly anything

[@RogerODonnellTV99Xoutof10]

The R22 was designed in the early 70s, the G2 in the 2000's to EASA standards. Its like comparing a 1970 Buick to a 2019 Volvo safety wise but the R22 is cheap and has enabled a lot of pilots to fly, it has also killed a lot of people and has been severely limited in operation in a lot of territories.G2 has 150k hours on the fleet and is not responsible for one fatality.

[@BenC20B]

@@shazam6274 in my opinion a lb/hp comparison doesn't mean a lot. All it shows is at sea level they all have a similar lb/hp at max GW and max take off power. What matters for altitude performance is how much hp the engine has in reserve at sea level. Under the conditions used in your comparison the G2 engine is closest to its max avaible output at sea level therefore it will run out of reserve power first and have the worst altitude performance.

[@killerb1919]

I love your videos and I am subscribed to this channel I've always wanted to be a helicopter pilot people need to know how expensive it is that's what's stopping me!""""👍🇱🇷🙄

Another rough day at the office!

[@chriseaves9762]

“This helicopter is very useful up to about 4K feet”. My home field is 4200ft in a mountain region. Micha hates Enstrom but I can do a lot more in my F28F here than I’d be able to with a Carbri. Cabri are pretty, and have a lot of nice features and if you live at low altitudes, great machine. Will be interesting to see what the 4-place version is like.

[@cpcgaleforce]

Amazing how you kids keep those eggbeaters from flying to pieces. Knew some Nam pilots ,back in the day, and they were a swarthy lot...you kids are so smooth with your machines. Watched the circumvention of the globe -twice. WOW !

[@comedycopter7908]

Comedycopter.com. My Schweitzer lost power landed on a golf course Road or touch the tail. It's destroyed. Now I have to fly one of these. I've only flown Schweizers

[@rustusandroid]

The Cabri also WAY safer than the Robinson, which is NOT a good training heli IMHO. At least you know there is no chance of chopping your own boom off with the rotor.
