Most carbon fiber props of that size, 68-72 inch will be around $1000 USD.

I am not sure if this will help you or not, propeller discussion on RWF.

Yeah...those stock blades truly SUCK!
They were made to be noise compliant and in order to achieve that they took the material and the efficiency out of them.
Truly a poor design and workmanship on the stock props!

Warp Drives seem to do just fine on Rotaxes even though they are a little heavier. They have a reputation for being bullet proof. Lockwood who make my Aircam use them standard on the Aircam with no problems that I know of. I have Sensenich, love them, and their simple pin balancing system is hard to beat, but they are pricey.

There should be lots of options over there in the "euro" market I would think,
Found the "AERO" website,

A slightly heavier prop (in balance) would not be any harder on a gearbox than a very lightweight propeller... any propeller is hard on a gearbox if it is out of balance or you let the motor idle too slow... like when you see someone with no brakes or poor brakes trying to idle and you can hear the motor/gearbox chattering.... once the motor is reving at a higher speed, it all smooths out.


Even if you arent worried about delaminating props, it is good to put some 'helicopter leading edge tape' on the leading edge of the blades... stops sand or grass seeds from sandblasting the leading edge of the prop ..... and can help prevent delamination from small rocks and stuff chipping at the leading edge... the tape can be easily peeled off and replaced if it gets any damage...

expensive, but you only need do the outside 2/3rds of each blade... so about 18" or so from tip in each blade. Stops moisture getting at leading edge too

Warp drive is tried and true... melikes

You can get 2" 3" and 4".... I used to use 3"

Scott, thanx for the link on Aero Prop.

I have been asking..... Here is the story AFAIK:

Once upon a time there was Aero Prop - made by some people.

Then they split up and one guy kept the name Aero Prop. The other became Luga prop. He now calls it "NRprop".

They both make the same propeller - same quality, same price.

Someone else - "mostly in Canada" - sell the propeller as Koolprop. Higher price, local service. Probably also a good deal for Norteamericanos.

Someone named Meglin sell the Luga/Aero prop under his own name. Another Ukrainian.

I didn't like the HTC, which had delaminated from the foam inside. And the IVO is soft and the one certified is the expensive variable-pitch version.

In the UK a Woodcomp is certified also. So I could buy that, but I'd much rather choose myself.

I was then told: Buy the propeller you want - then we'll figure out how to get it approved. Yeehaaa

So now I'm sitting here, money in hand so to speak, and tossing a coin. Which prop will it be?
Luga or Aero? I have to check my old propeller tomorrow to see, which mounting holes I can use before I order..

Cheers
Erik

Sounds like a plan Erik!
The only info I have is from Tango Gyro, I was talking to Alex and what He told me was that
Luga prop had changed the mfg process, changed resin suppliers, or something to that extent, then there were several instances of cracking at the root of the prop on the Yamaha powered Tango's, and Luga would not warranty the work. So Alex changed to Aero, and from what I hear the Aero will handle the higher HP and they will warranty their workmanship. So that's what I hear over on this side of the pond.

On a side note wasn't one of the guys originally involved with Kiev prop? And factory got destroyed during invasion of Ukraine.?

I just ordered an Aero Prop from Ukraine. Three scimitar blades, 68" with metal leading edge.

I could buy one from NRprop (former Luga) - same prop, same quality, same price.

In the end I had to flip a coin and it landed on Aero.

The price is quite right - most other props are much more expensive.

The price of the 6-bladed e-prop is four times as high - and I might pay that if it was much better.

I think this one is certainly good-enuff...

But it will be at least "Two Weeks" before I get it.

And I am still waiting on unregistering confimation from the swedish register.

It can't be registered in two countries at the same time.

The day before yesterday I spent at the airport. Checking the carb floats - perfect.

Picking up and fitting new 16 mm fuel lines from the tanks.

Then I have to check the small fuel filters inside the electric pumps and change oil and filter.

Probably the spark plugs as well. Great to be working on my own flyin' machine. What a feeling...

Cheers
Erik

I'm happy for you Dude.
Just don't become another statistic or example.
Take your time and never get over zealous or excited.
Do it by the book.

Hi Jake.

Don't worry.

Even if I should get too happy, I HAVE to go by the book.

At this time there is a fine balance between cowboying and needed regs.

Mostly it's the application of common sense.

Now I'll go buy a set of nav/strobe lights (Aveo Powerburst NG) - for safety, as gyros are hard to see.

And I think it'll give me a more "official flight" feeling, when turning them on.

Dampening my internal cowboy, making me fly by the book.

At least until I know how.

Cheers
Erik

You could always add a smoke kit...

That would be a great idea Scotty...

Then he can have the local fire brigade and news helicopters following him... when neighbors ring up thinking his motor has blown

Good idea after they get used to him flying around tho

Any ideas where he can get one?

So, I passed the first 4 exams...but now there are 9 of them.

And the powers-that-be has upped the price 50% in the two years, since I passed them last.

Well, it's "the only shop in town". Worst of all, it's now 9 exams (hm, each just 16 questions tests) -
but one can only show his/her face 6 times total. If all are not passed within 6 attempts, I'll have to start over again.

I have fixed (wrong size hole in hub) and mounted the propeller, but I need to find another
way to route the fuel lines from tanks to filters to electric fuel pumps. No space there. But I already cried for help on that one.

I bought a set of LED nav lights - also have to figure out the wiring. And I just got a mail, where Spruce.eu offer another set for way less...

I have to buy and fit a new 8.33 kHz radio, since I plan on flying through Sweden on my way to the rest of Denmark. No other way...

I'll of course choose same brand as the old - that's the cheapest and it's plenty good enough. Just need to check wiring.

The problem popped up because I bought a Flycom helmet in England. They say, there are differences between
these two Funke radios. I'll need a higher gain on the mike, they say. So I told them to go ahead, because I'll order the ATR833S.

So, I am still at it. Just thought you needed an update.

Cheers
Erik

Hey, I just found my Wolverines sticker...

Keep at it Erik!!
