Hirobo wins in South Africa - AGAIN - I wish I was flying F3C again
I know this has been posted in the Hirobo forum - but I don't care about duplicate posts (actually - this is changed so it's not a duplicate).

I have to brag -

My long time mate Henke Beyers won the South African SA National Champs (F3C hence it's in the FAI/F3C Forum) after a LONGGGGGG break from F3C.

What is even cooler is that he won with an electric Eagle 3.... I'm not sure what head and other equipment but I'm hoping that he will come on line soon and tell us exactly what setup he has (probably in the Hirobo forum).

For those of you who don't follow the electric Hirobo threads, here they are... There's a lot of good infor in there on electric F3C machines

Makes me want to fly F3C again... (What's this new P schedule......!!!!!!)

May we'll see you all in Italy..............

Cheers

Hi Marc

Thanks. Competition were tight though.... only a few points in the end. Two year break were good, gives you new perspective and motivation especially with the new P schedule. Wind was blowing heavy today with some gusts, which makes that hovering a handfull. Anyway everybody flew well.

My Eagle 3 VPUS got the following in:

New SSZ5 F3C head
SAB 705mm red devils
Scorpion 500KV motor
Scorpion motor mount
9.7:1 gear ratio
2x 6S Hyperion G3 VX 5500mah
Kontronic 80HV ESC
GY 520 w/BLS251
S9255 servos

Regards
Henke

I'm so glad you used a VPUS model, you only need a 10C transmitter or something, none of that CCPM mixing nonsense hence less work for the transmitter to do. And the VPUS system is such a marvel to fly with.

I take it the blades were SAB 0208? Are you belt drive or torque tube on this Eagle?

I don't want to convert to electric, but it looks like I'll have to on my new Eagle.

Henke's machine is super clean! Its one of the nicest i have seen, well that one and the other flying in the same class. Wind was bad that day but the guys made the best of a bad situation and the EP machines kicked ass. Im now wondering if i should be heading the EP route...hmmmmm

I heard the wind was strong!!!

How did the helis handle it in the hover? Were all the F3C machines fairly stable or did they tend to drift a bit? What other machines were flying?

Cheers

The machines were thrown around a bit in the hover routines but seemed fine when in flight, The pilots may have been fighting the sticks to keep the helis in a straight line, maybe Henke can comment on this.

As for the machines,

Hirobo Freya's IC and EP
Jr Sylphides IC
Jr Airskipper hybrid EP
and 1 JR VibeSG
MA Stratus EP

These were in the F3C class. Other classes they had TRex 600, 700 and TT Raptors.

rotophil, the Airskipper uses a K&S head or the sylphide head if im not mistaken as for the EP setup im not 100% sure. Some guys dont like to share their setup which is understandable :-)

Good head choice for sure.

No helicopter is perfect (you can read a lot into that) and gyroscopic precession is never at exactly 90 degrees no matter what the circs are.

Having a rotor head setup where the phasing can be adjusted should be a must for an F3C heli.

The wind was disappointing, so the true stability of the EP machines couldn't we shown. However testing showed that the EP machines because of it's weight is definately more stable than IC equivalent in the hover. Flying is definately easier in wind, as the demand in power is met straight away. Well in strong gusts, the same old technique applies....speed in the fingers.
