Very interesting.
Voodoo - I reckon you should modify the Swist and install a 5035 !

I have been working on trying to get a great outrunner for my Swist for months now,EASIER SAID THEN DONE when you live in the states ......But I will not give up .....I am one of the biggest wanna-be M Koch's out there

I would use a Scorpion 3026 or 3226. 7x10 APC on a 1400kv motor will give you about 2,5kW with 6s. Enough for one of my most dramatic in flight breakups ever (with a not so suitable airframe)!

Voodoo what is the fuse diameter where an outrunner would bolt on? Also you are kind of dictated by the cell size and count, i.e. no point having a big fat low KV outrunner when you can't get more than say 5 or 6 cells in the fuse.

So you have to work out your KV/Current/Voltage that will work for a given outrunner and prop. Looks like 6 cells might be the max for a Swist fuse? So perhaps that is the driver for everything else - i.e. a 1100-1600KV outrunner, propped accordingly?

I think i need to start a thread,last thing i want to do is have Marcus's thread get sidetracked due to my insatiable NEED 4 SPEED ..... I was just responding to War Machine (or maybe deep down inside it was a cry for help ) Sorry Marcus.

Hello guys, I am ignorant about the folding props for speed, do they rely on centrifugal force to hold a disk or is there a stop keeping them from coning forward?
Next is, to you knowledgeable guys, if I am using a 36-65-1 ARC with a 7x6 or 7x7(in a draggy airframe by speed cup standards)hitting 180mph, what type of hot outrunner/folder combo would do better, less amps and noise etc?
Most of my experience is from q-500 and q-40 in the 90's, I still like to go fast but find the need to go faster, after finding the thread there is a wealth of time invested from you guys and I personally appreciate it.

Would or could one of you fellows post a link or two to motor knowledge?
Please and thank you
Tom

hey Marcus, your very old Thread of building Raketenwurm and Eisvogel inspire me to build my F5B molds and start building this toys.. thanks for the good info you share with us...
this new class F3S put the high performance models in a whole new level of technology,
Congrats!

André

may be, its interesting...

this kind of model is not only usable for speed:
in hotline configuration you can reach (very silent!) good climbing speeds:



with 12x24 / 56 / °0 / 3 blade + 7S 3700 and 150A in climbing = 44,6m -> 397,4m = 352,8 m in 5sec = 70,5m/s in 5 sec average. or as long you want, if you are able to follow with your eyes and it is legal at your place.
the climbing after switching off the drive reaches almost up to 600m height.
(600m height is the legal border at my place here in germany)

also thermical flying is possible:



you see more than 30min pure thermical flight....
at 16:10 I was forced to bring it down brutally because of hitting the legal border!
but comming straight down more fun than a problem with such strong model.
so you can use such plane in allround configuration all days and with only another airscrew and battery for "real" speed:

Ralph,
They were very interesting graphs!

What kV would that motor be?

Regards
Peter

its a HK 4235 with high amp winding and 495/V and 550g weight.

also marcus uses this type or stronger ones (4535) on the bigger models.

if you want to use smaller airscrews or another number of cells you of course need another n spec.

Ralph,
Thank you.

I'm planning on using a stock HK4525-520 Ultimate with Koch 9.8x17 blades on a RFM 45mm spinner on 12 cells. Do you think it will last 8 second WOT runs?

Thank you in advance

Regards
Peter

I think, this will not be a problem.

you can expect about 17.500 -18.500 depending on your battery because of 180-200 A peak.
with a aerodynamically really good model and >200m dive you could reach up to 400 km/h with such setup.
or 375km/h with a bader one.....

Thank you.

I was yesterday on the Horizon Airmeet here in bavaria / germany.
Top Pilots with top planes and doing all great show from all different kinds of modell aircrafts.
Weather was TO GOOD - over 34 degrees celsius and the hole day sun without a chance to find some cooling. crowd around 10000 ppl.
Met Andreas from HJK Speedwings there and have had a great day.
Also too met Markus and Stefan, was nice to met the Guys in real, very nice Dude´s, very amused to met all the ppl. I know only from here or telephone. Also to saw the Thyphoons flying. great show and real silent on the way in flight.
Only pi**ed up point was - the organisation was very clever, was a 2 meter high fence there between the crowed and the flightline. and on the flight line a tend and lots of ppl.
so not good for doing a good video. also too only blue sunny sky what makes it complicated, and my video cam striked that I had to take the video function out of digicam.
for these who interested here are 8 seconds from the start.
and two pics one before Markus flying and one after flight together with Stefan.

Hi speed-guys!
We are back from the Horizon Airmeet and its was greeeeeeaaaaaaat !
Only top notch pilots with amazing models and skills i only dream of! The only thing which was a little too much was the heat on the two days !
Some displays gave me the creeps like "Mr. Marchetti" and his son, he in the original maschine and his son with the model together in aerobatic flights exact to the music! Absolutely amazing! But not only at daylight, even in the dark a night-flight show with about two hours and a big firework enlighted the night!
Stefan and i had three flights together on this weekend with flights against each other at speeds above 400 km/h, which gave me adrenalin-flow enough for the whole coming week ! Interest on our Typhoon-models was great at the "meet the pilot area" and i hope we could answer all the questions! It was also great to meet some persons from RC-Network and from here like Rolf, to get a face to the nicknames ! I also met Andreas from HJK-Speedwings and had a closer look at his models like the LP1.1 and the new Monster! He did amazing work as a "one-man show" with his models! Respect!!! And believe me it is not so easy doing this job for living! Nobody realizes the hours which are needed to produce a high quality model! Take the Typhoon XS as example: about 300,- Euro of pure material is worked in such a model, working time to finish such a plane without electric installations is about 50-60 hours plus 72 hours under vacuum! So if you want to earn money for living after tax, prize of such a plane should be above 1500,- Euro which nobody is willing to pay!
All in all a great weekend to meet pilots like Quique Somenzini, Sebastiano Silvestri and a lot of other top notch pilots!
Looking forward to the next year!
What a pity i had no chance to get to the US Horizon Airmeet in a few weeks !

Ciao, Marcus
