Default GP Super Skybolt .60 electric conversion - step by step

Hello guys.
I'll start putting together a kit of an ARF model that I bought about three months.
Super Skybolt biplane is the Great Planes .60.
The kit was purchased in Espritmodels and reached 100%
It cost U.S. $ 400.00 with shipping and tax paid. Still came out much cheaper than if purchased here.




Some pictures of the model:










Data model:
Wingspan: 145cm
Length: 134cm
Wing Area: 924 sq in (60 dm2)
Flight Weight: 3490 g
Wing Loading: 19.2 oz / sq ft (59 g/dm2)
Requires: 2-stroke .60 -. 75 cu in (10-13 cc) or 4-stroke .70 -. 91 cu in (11.5-15 cc), 4-channel radio w / 5 servos.

Electronics that I use:
Motor: E-max BL 4030/10
Propeller: 13x6 Master Screw
Speed ​​control: 85A Turnigy
Servos: Futaba S3010
Battery: 6S 5000mAh 20/30C
Final weight: 4700g

The difficulty I'm having so far is how to change the battery because the canopy does not open.
I found some on the net electrical Vercoe where the battery goes behind the fairing, but the battery that I use is great and so will be impossible.
Remove the wing to replace the battery would not be as complicated as the mounting system is very simple, yet is also out of the question.
Use only a battery and recharging aircraft in no way. hehe
The best way I found so far would be to cut the canopy, but the fuselage structure will also be cut and would have to make some reinforcements later.
I would like to help me think of some solution to this issue.
Thanks

As I only bought Heico 13x6 and was afraid that the engine would get weak I decided to do some bench testing.







The battery was fully charged.

Data:
V.............RPM..........A............W......... Kg.........Km/h........Stick acelerador
23..........7900.........25..........560.......3,1 .........78,3................100%
23..........5900.........10..........250.......1,6 .........58,4.................75%
23..........4500........4,5..........120.......0,9 .........44,6.................50%

It seems that will be an economic asset.
With full engine would give a 12 min flight. It would be great.
If the model fly well with 75% of engine will give a 30 minute flight. A lot.
Motor speed and do not heat anything. It is all very normal.
I was surprised with the performance and horsepower.

Compared to my Tucano with petrol engine that weighs about 4.5 kg and has flown very well with 13x6 running at 8400rpm, which gives about 3.5 pounds of thrust, I believe it will be good for this model which will weigh nearly 1 kg less.
What do you think?

Removing the box:

Box inside another box inside out. All well protected.







I started by assembling all power train.
I thought it best to begin with due to the fact that part of the fuselage to be without the set of tail. So it would be easier to work. It really was because I needed to support the fuselage on the ground to make some adjustments.

I measured the distance between the fire wall and exit the cowling in order to cut the dowels I used to make the engine mounts.
As the manual was given almost 1cm apart. The engine would be too forward.
Unfortunately, the camera crashed and I lost the pictures of the cut billet.
To make the drill holes used for wood and then went with their BRCA widening.
I left the hole up more just and the other three looser in order to have as adjust the position after spending the epoxy glue.

With the support rods screwed into the engine passed the glue and the engine fitted to the fuselage fairing put the spinner secured with tape and to fine tune the distance from the spinner before drying total:






Hitting the motor position.




Now just wait a while to dry.

Now that the engine is already in place did the drilling of fairing:





I managed to solve the problem of entry to the battery.
I put the battery positioned next to the model and saw that you could put it down between the cowling and landing gear.






Soon will start to make cuts in the fuselage ...

Today I made the cut for the entrance of the battery.
Then I put some foam and Velcro battery is securely attached. Before that must complete the assembly of the model to see the correct position of the CG.










Some pictures with the battery inside the model:











Now just finish the assembly and set the CG and then secure the battery in place.

While the wing dries I'll take to prepare the wing up and start moving in the fuselage.
Post new pictures soon ...
