Well done Jacko!!!

The Monster 1.1 is on the way from Germany and I should be able to give you a good review in a week or so with a build thread and flight video's to boot!

Jacko, it is a big risk, that your baby monster will "feal" way faster the the big one, even if you get 20mph more speed...Better to do some high altitude drop down low doppler speed runs with the baby first and smash that 220mph

My 7x10's arrived from AMain (fast shipping) But still haven't received the thermal epoxy or the batteries from HK

Decided to cut one last hole for air...since my Ice Lite 200 is now an Ice Lite 300 (in the test pilot area now):eek

The NACA is just in front of the ESC and will pump air onto the back of the ESC directly. Didn't want to do this...but the 7x10 is going to push the amps at WOT to around 300 I'm guessing.

With the fan in the front and the outside air ramming the back I hope to keep the temps down on the ESC which had been creeping up prior to the mods.
I'm gonna ring this ESC out for them!

YEOOW.. the Q40 prop (7.4x7.8) came today...beasty looking thing compared to the 7x9&7x10 Sport!

You should have seen the 7.4x8.1 Meanest looking prop ever!
Quite different than the one in your picture, with a straight part in the middle. I use it in one of my foamies attached to a Mega 22/35.

The only thing is you're limited to approx 250 mph pitch speed with a 7.4x7.8.... I didn't do the numbers exactly but you're hitting max tip speeds at this pitch speed.

only low rpm /amps are enough to get the needed thrust.

Is that data correct? Just under 4KW to turn a 12x24 at under 12,000 rpm seems excessive. Your motor/prop can't be very efficient?

12x24 @12000rpm isnt a small load

I've achieved 11,500 at much lower power levels i.e < 1.5KW
I must have a much more efficient prop and drive system, and it's a 12x25.

So Darron, what's your setup?

Was that an in-flight data log?

darron,

you are right of course.
this power system and prop is really so bad......

You're previous answer, before you edited, was that this was a 3 blade setup.
That's cool. Would be interesting to see the 2 blade data for comparison.

It was a with a Neu motor +GB and a Saw prop with my D05, but it was too hot for F5D competition so I moved on. It was also level flight, no diving from 400m and turning 180deg every 2.5 seconds. But an F5D model is much smaller and lighter than Scorpian-fan's speed models which require more thrust (and power) to get closer to pitch speed.

I have tried offical F3S speed runs (all 4 gates) with my F5D models, and I can say that it's not easy at all! The model literally disappears as you transition from diving to level flight with the model over 200m away. Much better to use the bigger models or fly without the big dive.

Hey guys got a question about motor wires on these high amp applications
My motor wires are really long due to the fact I had to put the ESC back under the wing (balance issues) what size should they be in relation to the size of the wires coming out of the motor?
Also CAPS...should I add caps to the setup since I am pushing it a "tad" beyond the limits?

Got the NEU back last night Will be installing everything back into the plane today and might get a flight in tonight just before dark with the 7x10.

its almost impossible to compare in flight data with different models.
and its also impossible, to get useable teststand-data with an light and weak f5d prop.

this is a 2 blade 12 x 24 for f3s (50mm root distance), tested up to 12kW and a 12 x 24 for f5d (30mm root distance) for the "normal" f5d load.



this 3 blade system was able to reach 414km/h between the gates.

it also was able to get a 320km/h average with "power on" in horizontal flight at the "flight in" gate.
the max. diving speed of eagle I found with about 270km/h.
here I assume, it was about 250km/h max.
so you can calculate the reached acceleration. if inflight speed is 250km/h and average speed is 320km/h the speed at outflight gate could have been about 390km/h.

I develop my models not primary to get max speed - I'am >50years old and I'am a much bader pilot with bader eyes compared to our "young wilds". so I try to find a way, to be fast with my personal possibilities.
this means for me good acceleration, high power and powerduration (actual drive can take 270A for 20 sek on teststand without burning) and very silent drive system - so I can fly directbehind our little cottage.

a good example:
with chimera I reached 380km/h max.
my friend kai was 460km/h fast in his second flight through the gates......
now think, what could be possible for him with my eagle.
