when i was purchasing the motor and prop i thought that the prop was too big for that size airplane, 10x5 prop, and the plane is only 17"!!! could i get better proformance with a different prop?

8 x 4 Direct Drive Black Electric Propeller (EP-8040)
or
3-Blade 9 x 7 Black Electric Propeller (EP-9070x3)

a scale prop is about half the size as the one the specialist gave me a my lhs.

Hi PrOtRoN,

Nice plane u bought, i'm almost finist mine today .
Just need to glue the upper stringers in the wing and fuse. And i need to make some hinges.
I was planning on making mine Rubber powerd with the rudder/elevator controled with bitgear. I want to use the rubber to take it up and control the glide back down.

One thing i dit was using lighter balsa, the stuff supplied was like hardwood so i used these as templates.

Here are some pics of the almost finist framework 10g with canopy

Good luck on your build.


Mark.

nice pics

i was surprised by how the airplane came in the box. the rubber bands and prop wasnt in the lil plastic bag and they fell out first. i saw only 3 sheets of balsa wood. and then i stood over the table and thought that the box was messed up and i was missing a sheet of balsa. but no 2 sheets were the body and the wings were on the other sheet.

2 sheets of the balsa wood are thin and light, the other is heavy and thick. im going to dope the whole plane when finished for some strenght

but to know that your airplane in the pictures weigh 10 grams is great!
the weight that i thought the plane was gonna be was at most 28 grams, covered and doped,

plane - 28g
motor - 23 g
rx - 10 g
2 or 3 servos @ 6.5g each
battery - 15g
esc - 6

my total is about 95 grams

right now im trying to figure a way to mount the motor, there is no cowl to this kit so im puting the motor in after my 2nd step. here is some pictures of what im doing

I think your plane will be most difficult to fly with that huge prop and gearbox.
Too much torque on too small an airframe. Take that motor out of the gearbox, pull the pinion gear off the motor and put on a gws 3x2 press on prop.
What battery? An e-tec 250?

Protron,

It would serve you well to read and really digest this thread:

https://www.rcgroups.com/forums/showthread.php?t=308433

The planes being built are about 17". There is much detailed info on equipment and weight. Most of the planes are comming in less than half the weight you are estimating. At 95 grams, or anything close to it, I think you are setting yourself up for dissapointment. There is nothing wrong with your equipment, but the plane you have picked is way too small to give a reasonable wing loading IMHO.

Hey Whacky, ziet er erg goed uit!
Kun je misschien even doorgeven wat het gewicht is als hij klaar is (met verf & bespanning, maar zonder elastiek).

its an electricfly 2s 340 mah lipo battery, im not sure but i think the its got a safe chip in it that saves it from explosion?

i got some balsa wood and some plywood for the servos and motor mount,
plywood is great, super thin and fits in place nicely. plywood is use for strength.

i also baught a 5x5 prop. i tried the motor out with the new prop and it has decent amount of thrust where its jsut pulling out of my hand. my dad said use the stock prop its got more pitch! so i tried it and it was pulling out of my hand so much it would take off with the wings on. so i think im gonna use the stock prop, too bad i only have the one that came with the kit and another from a stuka kit. by the way the stuka is way too small to convert, i dont know how the member here did it.

i will post some pictures of what i did today but it has gotten late. i got work tommorow so that will be the first thing i do after work.

oh yeah we had a crash today, 1 casualty... only me and my father have survied the crash.
