Default RE: New Krill Spark Evo I- Build Thread.....



hello!

most (I'd say 60% or 70%) of the noise of an outrunner is made entirely by the prop tips. the falcon hobby 21 x 14 is ver efficient on this matter (i've been using it for like a month now. In our tests, and subsequently, my opinion, the real noise of the motor itself, say q80, q60, AXI, plett 30-10 is nothing compared to the real noise generator: the propeller. if you stand by the side of the propeller while turning and see the tip going back and forth from the propeller plane, that is generating a lot of noise. you do not see this on carbon props since they are much more sturdy.

two other things affect total final noise:

construction of the fuselage: wooden (say japanese or home made) kits are more silent than composite kits, like an integral, a spark or a Xigris. these last fuses work like a drum magnifying the vibrations in a sound box. BH made us realize this issue here in Colombia

how sturdy the firewall is: we've tried from an 1/8" lite ply one side glass laminated firewall, 1/8" lite ply one side glass laminated with a carbon rod firewall on the back, up to the 1/4" carbon fiber laminated plywood. this makes a real difference. you feel these effects specially on the integrated loop in the figure M, on the vertical 8 before the spin, etc.

but for the motor itself, alone: the outrunners are all so silent it makes no difference. even for the chinese (ok these are a little louder but not significant). when you hear an e plane at cruise speed you only hear an aerodynamical noise, just the sound of air.you hardly hear the noise of a bearing or the motor itself.

I remember my father fighting the noise in a Curare and on an Arrow while he had a Webra 61 Long stroke rear exhaust and a tuned pipe. they fought the noise a lot with the propeller selection.

Andrew, I did not mean to hijack the thread sorry...

Can't wait to see the Spark Evo on the air!

Here are the weights of my Evo:

Fuselage: 776 grams
Canopy: 171 grams
Bellypan: 67 grams
Right wing: 378 grans
Left wing: 377 grams
Right stabilizer: 126 grams
Left stabilizer: 124 grams
Landing gear: 122 grams
Wheelpants: 43 grams

Not very light, but ok.
Should be no problem to get it within the 5050 grams limit.

I think that is very light - lets do some math:
Motor (Q80) = 630 gr
ESC = 70 gr
Prop = 70 gr
Wheels = 15 gr
Servoes = 210 gr
Ext cables. = 70 gr
Pull - Pull = 10 gr
Links inc rods = 30 gr
Battery tray = 20 gr
Glue = 30 gr
Batteri = 1150 gr
Receiver = 25 gr
Receiver battery = 70 gr
Total flying weight = 4584 gr.

I think that is a very very low weight, not easy to get lower.

It's a little porky. [] Your estimated weights are a little on the low side compared to actual weights.

He's going to need to watch his weights if using the Q80 for sure. Use an Excel spreadsheet to get a better idea of the final weight.

Cheers,
Jason.

They forgot your wing tube? [&:]

How did they assemble it in the photos you posted?

Do you think 4000mAh will be enough battery for the Advance in-runner?

Cheers,
Jason.

Used a smaller wingtube just for the photos.
I hope so, but I don't know for sure.
With my C50 with 22x12E prop I can fly the F11 sequence with ease on a 4000mAh pack.
Hope the Advance will use the same amps as the C50..

I have received my spark Evo as well!! It looks amazing!! The fit and finish is even better than my sparks I have now. I have started working on the wings and stabs. The chin cowl and canopy are mounted. I have decided that I'm going to put a C50-14xl in this model as it's a worlds year I want to use equipment that I have used and know. This was a tough decision to make but its what I felt was best for my situation.
I'm actually driving right now to Yuma az for work so I dropped the evo off to darin peirce a great pattern pilot and builder to finish up. Once I'm back I'll give flight reports!!

Jon .....

Simply mount to the front with four screws M4 (on a 2mm carbon backplate) and from behind with a 10 mm dowel inserted into a backplate of 2 mm. This dowel was inserted into the rear bearing motor .
I seems to be no need to hold back, but for security reasons ,I consider it important.
Not be much weight gain.

If you believe another good system will be taken into consideration.

I enjoyed watching the quality of this new design is exceptional.
I feel good feelings.
The removable hinge system at the rudder is a great idea, which will save space in transport boxes, among others things.

cheers.

Andres Girabel. ( the builder)

Thank you for the speedy response. Although I have not seen a Spark before the quality of this plane seems quite impressive
To be clear you are mounting directly to the nose of the plane with 4mm bolts? Are you placing the 2mm carbon plate between the motor and the spinner ring inside the plane?
