E-Props ...who has first hand experience with these

News from Eprop

 

INFORMATION: now E-PROPS Durandal propellers TBO = 4000 hrs. For both EASA certified or non-certified propellers.

 

[Carbon Canary]

Is there any calendar TBO ? I believe DUC imposes a 5 year and/or 2000 hr TBO, hence my question.

 

Also interested in any direct comparisons between DUC Swirl 3 and the equivalent e-prop, all other things being equal, if one exists.

[Kyle Communications]

Eprop beats the DUC no issues..4000 hr TBO. not sure on years. I dont think it really matters at 4000 hrs

Some DUC’s were 800 hours and like Mark said Eprops were 2,000 and now 4,000.

[Kyle Communications]

I have asked Eprop the question and will post when I get the answer back...most likely tonight

 

[facthunter]

4,000 hours seem s a lot of life for a prop. I wonder how they  arrive at that figure?  Nev

[Kyle Communications]

They do extensive testing and destructive testing..they have videos on it

They would have not got the approvals if it didnt hold up to the hours

The paperwork approvals is attached here

No its not...he tested it to how he wanted to...NOT to how the props are designed to be run

 

His testing was done as if you have a IFA or constant speed. These props are ground ajustable and designed to run a max rpm on a gearbox driven engine

If you set them up as per factory instructions you will get a substantial improvement in performance...more than 50 customers I have sent props to with maybe 15 or more different style of aircraft cant all be idiots..they know what performs better than what they had. I have not had one customer that did not get substantial performance increase

How many hours does the oldest propeller have today?

[Kyle Communications]

Got no idea..but some of the aircraft get a lot of use

 

[facthunter]

The most impressive prop I've experienced is a Kiev prop on a HKS V twin of about 700 cc. It easily powered a Normal  Skyranger two up. That's a while ago and equal or better may be around now but it was good. The motor ran a bit hot but I can't blame the prop for that. Nev

Are you a distributor for e-Props?  

[Kyle Communications]

Yes I service Australia and NZ

 

[Kyle Communications]

I just had a answer back from Eprop on the time for their props..there is no time constraint only the 4000 hours due to the way they are made and the special material they use

Thank you for the follow-up.

 

if there is a like for like performance comparison against a DUC Swirl 3,

anywhere, I’d be interested in reading it. I will need to make a prop decision in about 6 months.Standard figment is a DUC.

[Kyle Communications]

All I can tell you is that there have been a few DUC props replaced by the Eprop here and everyone of the guys says the eprop is much better..quieter, more performance, super smooth also the engine starts and stops easier because the prop is so light. I have not had one person return a prop. Eprop give a 6 month return on the prop..If you use it and you dont find its a improvement and a better prop than what you like they will give you your money back....someone who stands behind their product

Carbon Canary..what is the aircraft ?..you may find it on the feedback

 

[Carbon Canary]

FK9

Feedback on FK9.

[onetrack]

A total of 14 feedback reports, with 13 of them from the one buyer/user, isn't exactly a balanced level of feedback.

[Garfly]

But Durandal and Glorieuse are the names of the prop types.

[onetrack]

Ahhh, O.K - apologies for my error, that clarifies things substantially.
