Finally...the flight of the Stork 2 Pro

Did maiden flight at BBAFC yesterday and it flew very gracefully despite of the windy condition. Not much of a trim was needed except for the slight down elevator was needed. Test out the chambering and it was well setup. Penetrate well during windy condition with a slight negative chamber. ( Approx -3mm )

Apart from that no problem of any unexpected move like tips stalling when turning at a very low speed. Very responsive and it is also very gentle with the landing. With a full butterfly flap down, the sailplane was really slow and gentle for touch down. It was worth the money...I guess you get what you paid for.

It soared beautifully.
Very sensitive to thermals.
Did a low pass for Vincent to capture the bottom side of the sailplane.
Start climbing to test the burst...climb rate is very fast due to it's light weight. Was using 4s 2500mAh and it did take much of the battery capacity. It was just perfect.













Testing out the Butterfly brakes...everthing seems to be just right.























Did a High G turn and it was indeed very responsive.

















Stork 2 Pro Building Process

Finally I have received my Stork 2 Pro which I have ordered from Soaring USA. It took 5 days for it to be delivered right to my door step. With full of excitement, I have decided to take it slow this time since Christmas was just around the corner back then. As mention in my last message, I will try my very best to capture some photos of the building process.

The kit comes with an electro fuselage, 3 piece wing with all the joinners, a bag of screws, elevators fins, rudders fins and some multiplex connectors.

I have also realised that I have miss out certain photos of the building process as I got carried away and by the time I realised it, it was too late to capture it...haha. But nevertheless, I kept on reminding myself "photo first before proceeding to the next step"...which literally I have forgoten all about it.

Well, here are some of the photos taken during the building process.

Got the MVVS motor from Soaring Composite and it fits perfectly. It's a 690Kv motor with a 15/8 Aeronaut folding prop.

Did an opening with a Dremmel on the side in order for some ventialtion. From the pass experience, the motor do get hot when climbing up to the desire altitude due to lack of ventilations.

Next I have installed the Rudder and the ball joint celvis. A pin was attached to the top of the Rudder fin and you need to slot it in and screw from the bottom. Very nice and neat design.

The elevator comes with a carbon rod and a steel rod. Trial fit to see if it's smooth. Need to sand off a little of the carbon rod in order for it enter the loops smoothly.

A completed rudder and elevator.

Servo tray, rudder push rod & elevator push rod have already been pre-installed. Just need to trial fit the servo.

For this setup I am using the Hitec HS5085MG digital servo for the elevator and rudder. Once it fit perfectly, screw down the servo and attached the push rod. Before doing so, you would need to center the servo.

Ailerons and Flaps compartment. Trim off any excessive fibers to create a nice opening.

Wrap up the servo with heat shrink. The aileron and flap servos needed to be epoxied on to the wing tips and center wing servo compartment. I have use a Hitec HS5125MG Digital wing servo.
Trial fit the servo on to the Aileron and Flap servo compartment before appling epoxy. Centering of servo is required before proceeding to the next step.

Once all of the servo fits perfectly and all measurements are correct, you can now carry on applying the epoxy to the servos. Once that is done, attached the pushrod.

The wing tips and wing center are connected with a carbon rod supplied and for the connection of the aileron servo, the micro dean connectors are being used. The multiplex dean connector are provided with the kit.

Trial fit the connectors before attaching it permanently to the wings. I have use a thin CA for it.

This are all the aileron and flap wires which will be pulled thru the wings. The ailerons and flaps servos are connected to the fuselage with a Multiplex 6 pins connectors. There are very little rooms space to run the wire thru...was having a hard time pulling it thru.

Have to do a slight modification as the kit only comes with one opening which fits only one connectors. I have decided to open up another hole for the 2nd connectors.

On the fuselage, there is also one opening for the Multiplex connectors and another hole is needed for my case.

Attached all the connectors to the receiver and place it into the receiver bay on the fuselage. Test all connection by starting up the transmitter and receiver. Once all that is done, you can now cover the receiver bay with the cover provided.

Once everything is completed, the last is to attached the servo covers which have been supplied with the kit.

The battery compartment. As you can see, I have made a battery tray in order to avoid the batteries from falling back. The ESC are above the battery and it did hold the battery in place.

The finish product....Stork 2 Pro at BBAFC. Check the CG and all of the throws. Did the appropriate mixing and settings and it's ready to take the sky.

Me and my Stork 2 Pro

Did a maiden flight today at Bukit Batok Flying field and it was a beauty to see it soared across the sky. Vincent was there and he manage to capture some nice photographs of the Strok 2 Pro. Will publish it once he have posted it to me via email.
