The Peregrine is renowned for its speed, reaching over 325 km/h (202 mph) during its characteristic hunting stoop (high speed dive),[6] making it the fastest member of the animal kingdom.
The 6.5 x 6.5 prop is probably the better choice for your top speed since it has a greater pitch and smaller dia than 7 x 5. I think the problem is your prop is going transonic with your setup. For the airfoil on the prop anything faster than Mach 0.85 is going to have reduced lift due to the pressure wave building in front of the leading edge. If you can set a RPM limit in your ESC to about 33,000 RPM that is Mach 0.84 for the 6.5 x 6.5. For the 7 x 5 Mach 0.84 is about 30,500 RPM. Cheers!
Another option which works with your 22.7 volt lipo would be to change to the Neu Motor 1509/2.5Y 1450 kV. 1450 rpm per volt with 22.7 volt puts you right at 33,000 RPM (assuming no voltage drop), but would be really close to what you are looking for with a 6.5 x 6.5. This is an expensive option where a cheap option would be to go to the "Turnigy 2200mAh 5S 30C Lipo" 18.5 volt lipo which would put you at about 34,000 RPM @ Mach 0.86. Cheers!
But I would also guess you have to mathematically match your motor with the power. Like if I ran a 6 cell 12 volt batter with my little 2200 I would probably fry it!
I am trying to make sure I understand how the math works so I can make a video that explains it correctly to help people buy the right stuff for there needs.
It is hard to do because manufactures all say different stuff. I though KV ment RPM, obviously thats not true here! Off to do more research.
Yes I am very impressed, I have discovered it is hard to find what kind fo motor will put out what rpm and at what weight to thrust ratio.
I have a little 2200 KV its gets the job done nicely but I have no idea why that motor works but its not near as fast as your plane running a 1800 kv I am using a 7 x 5 prop on it.
Im not complaining it goes nice does verticals no sweat but it doesnt have the speed yours does!
hi again Nooby....im running this engine on a 6S 40C lipo dont forget.25Volts ..thats why its going so fast..nearly 38000 rpm .. hope ive cleared some up for ya..feel free to ask what ever u wanna know! bye
Great plane, Just listing to it you can tell it has more to give you. Keep us up to date if you find a prop and battery that makes the wing tip melt. Ha ha
That thing is incredible! Great job man! Looking forward to more on the prop size changes and how it effects the speed. Thanks for another great video!
Right On BROTHER! That thing is insane!!!!!! Great flying. major props to your awesome camera girl, she did a good job tracking such a fast beast. Very good work by the Dutch Connection team! We will definitely have to work up some plans for this Jacques. Man I think I am going to have to get one of these motors too and make a SuperNova Extreme, hmmm sounds like a plan. Well keep up the great work, you are definitely the leader of the speed demons!
Thx Bro!..yep man get urself Neu 1509/2Y for ur nova jet man!!..that be killer...
you wont regret for sure..
im gonna notch it up to 8S soon for the next step LOL 8s Peregrine!! (secret still)
Yes i will start converting the cm to inches on my drawings..this one is a winner for sure!!..and thx for announcement of my FF pro plans in your last vid!
WHOA! Holy fast!! Your anticipation and look of nervousness before the flight makes me laugh! I think most RC fliers can relate too. (and the shear joy when you have those close high-speed passes) I appreciate your enthusiasm, and great videos! Had to watch a couple times! Thanks! 5*
That is some awesome watts man wow. Great flight jacques really handled well even at those speeds, I think before long your going to be fooling with the 200 mph mark great job.
