Don't Get a 3 blade 130 cm E Prop..... unless you want - More thrust (BIG DIFFERENCE from my 132 cm Scout prop) MUCH Smoother feel (less vibration at all rpm), and a perceived (not measured by me) lower sound level. Over all, very impressive! Thanks Travis
Great data. Love what you guys are doing providing a service for this community.
Good stuff! Thanks for getting right to the data!
Results from this are as follows ---125,2 blade Eprop@8670rpm=137LBS--- ---125,3 blade Eprop@8430rpm=145LBS------130,3 blade Eprop@8380rpm=153LBS------125,2 blade Helix@8580rpm=135LBS------((POLINI Thor 250 ,130,3 blade helix@15200rpm=191LBS---))
Mmm, interesting outcome. Thank you for sharing.
This is really informative guys. Thank you for putting this out. My personal quiver of blades are, all 125s on the moster 185+. My mostly used blade is the helix 2 because that's what it came with. I acquired a 3 blade helix and it definitely took me off the ground with authority yet after I filmed my friend takeoff in his powered hang glider I was working on touch n goes, slipped in wet grass with motor on with chase cam and sent my brand new chase cam into my new 3 blade. Had to rebuild 1 of those props. Still haven't finished. Have since bought a 2 blade e prop and used it one weekend and loved how much thrust it had compared to the helix 2 and 3. Also purchased the e prop 3 and am saving it for special grass occassions. Flying at the beach, sand and stuff gets picked up into your prop on takeoff and you will take some damage from it. Not much to much, just chips and little holes in your leading edges. I fly north and south shore beaches LINY with some inshore grass airiports and upstate in the mountains. Your info here suggests e props on data put you in the seat and off the ground faster and stronger. As well as possible climb rate. Good stuff. Keep it up 1 Up :-)
Pretty useful test... Thanks guys... Cheers
The three blade may run at a lower RPM because the added blade adds drag and weight. In this case, the lower RPM would not give you better fuel economy as the throttle is still in the same position. That's what I'm thinking.
GUYS THESE GUYS ARE SO NICE AND COOL DEFENATLY GO AND SUPPORT THEM THEY DO GREAT WORK I WOULD SUGGEST YOU IF YOUR GETTING A MOTER TO GET IT FROM THEM THERE MOTERS ARE NEVER BROKEN AND CLEAN AND THERE VERY NICE
Hi guys, nice video
Do you know if propellers you have test with 2 and 3 blades has the same profile, I mean, are the blades exactly the same in two models?
Have you guys had any problems with the 130cm on the parajet Maveric? I have heard of issues of people having prop strike on the cage.
Are you guys sure lower RPM is better by default? I'd have thought that load would play a part in that equation? Not trying to pee in your cornflakes, just offering up a thought... Thanks for the video, very interesting!
hey guys, any idea how much different the thrust value is if airspeed is 5,10,25,20 mph?
Would be interesting to see what fuel flow and manifold pressure difference would be between two and three blade props. Is the RPM lower because the engine is working harder to spin the three blades?
Yes, that would be the reason that the motor is running slower.
awesome guys!
Interesting data, very interesting! Is it possible if I could test a prop set if at your location? Try before I buy type test? LOL
Of course! :) No problem.
Lower RPM more thrust same motor possibly higher operating temps??
Thanks for the video guys!!
I would guess the other way, lower motor friction at lower RPMs, more thrust equals more airflow over the cooling fins? We didn't test this. :)
@@travcarrie Ok,my guess is the lower rpm at wot means engine is working harder to push the prop but that's just an opinion.
Would need to eye ball CHT for a bit to really know.
Yes slightly higher CHT but still ok, could be how carb is tuned
@@gordonrobertson6599 Aha.I am onto something,not bad for a HS drop out :)
Are you guys going to stock props for the Nitro?
We are currently stocking Moster 185 Props and Atom 80 props. We are able to get you 130/nitro/tornado props as well :)
Wow, the 125cm 2 blade eprop looks like it put out ~3lbs more thrust than the 125cm 2 blade helix. That's pretty shocking. I've always been told the Helix has more thrust. Also, I wonder how the 130cm eprop effects torque vs 130cm 2 blade?
Only 3 lbs more, but yes it did!
hey guys. i just tested the 130cm 3 blade eprop onm my moster 185 my20 and get only 8280 RPM. you guys over 8400 if i see it right.
and i feel thrust is very low compare to my stock noname 50$ 2 blade garbage prop.
i was expecting so much better performance from the eprop. something is strange...
That is very strange. Prop is not installed backwards?
@@oneupadventures5040 yeah people asked me same. of course was installed right. i continue figure out whats going on. thanks for your video. helped me alot for what RPM i should expect and what perfomance. so cheers guys° keep the blue side up
Make sure prop code is T-G35L-130, that is correct code Moster 185 with 2.68 reduction
@@oneupadventures5040 ah yes now here comes the weird part: my prop arrived and says T-G54L-130.
all friends which i fly here together say moster is either 2.68 or 2.86.
i triple checked my reducer ratio. near prop attachment stands 130mm so it should be 2.86.
but on the frame sticker stands MOSTER 185 MY20 PLUS 287. which is 2.87. the propeller eprop send me is for 2.86 which he said is right for my motor.
i am so confused. today when i test the 3 blade 130cm eprop it felt like i can stand normal. no problem holding the motor at full throttle.
if i do this with my noname 2 blade no name prop i can barely stand at 75% throttle. at 100% i need lean back and really put my back into it to hold the power.
there are 2 options left after i talked to eprop and got answer from mateo where he confirmed this propeller is for 2.86 ratio and its fine because he fly the exact same combo too.
1. i am nutz and my higher expectations lead me to the feeling that it have less thrust even it produce more and for some magic reason i can suddenly hold the motor at full power no problem.
ooooor
2. something is off and i am not getting full thrust for some reason. maybe my cheap RPM meter shows incorrect numbers and my carburator mix, gasoline or any other power related thing in my motor is bad. i saw you get 8400RPM easy. i can reach 8200 and sometimes a bit more around 8300ish. even i doubt that it would make such a big difference. and that would also still not explain why i cant hold my cheap propeller at full throttle.
your video is such a big help to figure out what is happening here
@@cloudpandarism2627 did you ever figure out what the issue was that caused the low thrust on the eprop
