Alea iacta est!


I've just placed my order for a Rush kit.
Hope to complete it in three weeks. My setup for this beauty will be:
PowerJive 120
Scorpion 4035 by GMauro
mini V-Bar
Savox SC1257TG
Futaba BLS251
Rail 696 and Rail 116
as usual the power will be guaranteed by 4000mAh 45C SLS batteries.


Pictures and videos will follow as soon as possible..

Hello Ben
only some pics:Alees Rush 750 pictures by 7_62x51 - Photobucket



I'm still waiting for blades and ESC, so i've ended the mechanical setup, but cannot get it in the air...

This is the core of the 4035 that will move this model:

Nice!!

That 7HV looks fat compared to the others lol.

That motor looks PHAT!!

[Rctintin]

Nice one Fabio, that motor will be a monster!! Nice Heli line up mate!

[7.62x51]

Thanks mates

the 7HV looks on steroids, and flies like it...

We thought this winding (5+6x1,5 YY) to overcome the 4525; i expect to have a strong but smooth torque. I plan to set max HS around 2100 rpm, kinda like the Compass.

Rush and 7HV will have the same blades, main and tail and the overall weight will be near, so their flight envelopment should be very similar..

Mauro's motor is ready and mounted:



Hope to maiden the heli tomorrow, but previsions are for bad weather..

[Jamin_00]

Nice, very nice

Let us know how it goes

That sure looks good Fabio, good luck with the maiden.

I need to get some of those stickers from Mauro!!

Today i had four flights with my Rush.
Wow, it's quick!
I'm still waiting for the Rail blades, so i did those first try using a pair of Spinblades 710 V2.
Very reactive cyclic although i set 90 into the agility slider of v-bar.

The motor is terrific; it push hard, having a lot of torque i had some issues about tail loosing authority.
I still need some flight to tweak the precomp for high rpm; at 2120 happens to loose the tail giving collective.

The pop, however, is embarassing and i set 12° of collective pitch.

Tomorrow i will try to swap main blades between Rush and 7HV, so i will fly the Rail 696 and i will take a pair of Radix V2 as last chance.

I've, also, a pair of Spinblades Matt Black, but i keep 'em for the TDR...

[Rctintin]

Nice one Fabio. How do you like Rail blades? I was thinking of trying a pair on my N5c seeing they were developed on that Heli.

How cool did the motor come down? It looks awesome, think I may have to try one!

Hallo Rob

Air temp was about 15°C, before thr flight motor can was near 25°C, after 4 minutes it was 49,8°C and the wiring 57,2°C.
Cool. I don't pushed it too much, i'm still trying to understand how the model flies; battery consumption was about 2500mAh for 4 minutes.

I flown Rails only onto 7HV, for now; i like 'em, i feel quick and crisp cyclic reactions, collective authority is good, they're stable in forward flight.

I did a little comparsion about CG position in blades i actually own:
Most inner CG is in the Spinblades 710 FBL V2, it is at 350mm from bolt hole;
Rail 696 have the CG at 362mm from bolt hole; Radix 710 V2 at 374mm and Spinblades 700 Matt Black at 391mm.

Tomorrow i will swap Spin and Rail so i will define how the blades feels and what have better cyclic performances.
