Anyone remember this guy? Rajath, maybe you did as you had seen it. So the makeover is complete for this guy and electronics are in place (well almost)
I will be finishing this over the weekend and post the test flight here..



Edit: Electronics used..

Motor: AX 2308N 1100kv brushless Micro Motor - on a stick mount
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5429

ESC: Hobbyking SS Series 25-30A ESC
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6460

Battery: Rhino 610mAh 2S 7.4v 20C Lipoly Pack
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7305

Prop: 5 x 4.3 - GWS EP Propeller
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10034

Servo: Mystery 9g Micro Servo

Control Horns: Plastic Horn baseless SMALL
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8236

Pushrods: very thin, Iron wire used in binding construction iron rods. Very effective and light weight.

RX : Yet to decide, I have ordered OrangeTX 6CH DSM2 compaitable or will use AR6300

TX: Spektrum DX6i

Ailerons and Elevators channels are mixed to act as ailerons as well as elevators. I am planning not to use the elevators in the back of plane as they are very thin piece.

Is this made of biofoam or high density thermocol and what is the thickness of the sheet?

And the AUW?

Was there a thread dedicated to this project or is it the first time we see it??? If its the first time then kindly provide the deatils(including the electronics used).

this is high density thermocol, sliced from the packing of fridge.

Wings thickness is 5mm and fuse's thickness is 15mm, I could have made the wings even thinner but this is thermocol and could easily break with that thin layer

Sorry for my poor vocabulary ... what is that?

All up weight - how much the model weighs with everything that's going to be on it when its airborne.

I thought so but then decided to ask... I have yet to calculate the AUW. Once I finished wrapping up everything I would tell the AUW. I am actually thinking which battery to use 500mah or 650mah and also little confused in 25A ESC or 18A ESC... suggestions?

Your motor has current range 6-10 A. So I think you can safely use 18A ESC and save few grams.
I case of battery you can use 610mAh 20C which gives you 610x20 = 12200mAh = 12.2 A. As per your motor specification it needs around 10A so u can use it safely. But is always better to do some static test using watt meter before choosing battery.

Hey nice work. Looks like you have been busy ever since you got hold of the fridge thermocol and the coloured tapes Thats one colourful model you got there. One suggestion though - Why not use black tape for the cocpit? Maybe black insulation tape? 

The only model i saw was of the one you were testing the other day. This doesn look similar though

Would like to be there for the maiden - can also capture a good video

Cheers

good work and thanks for replying to my queries.

The Tape gives a grate colorful look as well as grate strength to wings and fuselage too.

Thanks

Hey i noticed you bought control horns. Did you order screws for these as well ? Are screws needed (on hk site the reviews say screws are needed) ? If no then how do you attach them - glue?

Thanks, I will check. A related question... what if my motor need just 10A and I provide it 25-30A... any negative side that you could think of? How much access or less amp is good for the motor?

Sure, we have to maiden it on a nice open area... dont really want to try in the same ground. Maybe BEML ground. oh yeah sorry I shown you the scratch piper-j and not this one... my bad

I though blue body and black cockpit will not give it much contrast so used yellow instead, yeah this tape is very good in quality. I guess I need to get more in my inventory

Nope, I like to keep things simple. I make a cut in the body/wing using my x-acto knife and make it little big so that control can go inside. Then I first fill the cut with hot glue and place the control inside. to give it enough strength. see attachment.

I agree, just love the colors and shine it give. along with strength + flexibility to wings.

Your battery does not provide current on its own. It is motor which drags current from battery. So you can use battery of higher rating than minimum requirement of motor. Higher the mAh rating you use more the flight time you get.
So you should always use battery which is capable of providing little higher current than required by motor. 

Actually my question was related to ESC here... ESC provide current right or is it also same as in case of battery... like ESC provide as much as is asked by motor? so if motor is asking 10a and esc is capable of providing even 60a it will only provide 10a... right?

You are correct. Battery, ESC are provider and motor drags current through them, so they will allow only that much current which is dragged by motor. So it will be safe to use ESC and Battery as long as they have at least little more current rating that motor.

Another test video with elevator controls attached. Wings hot glued together in place with positive dihedral , vertical stabilizer hot glued.

Control surfaces are completed with channel mixing



Settings for MIX on DX6i

Mix 1: for Ailerons

Elevator => Aileron ACT
Rate L + 90% R +125%
SW ON TRIM ACT

Mix 2: for Elevators

Aileron => Elevator ACT
Rate D -125% U -125%
SW ON TRIM ACT

Cool, see I am learning

The servos seem to be hooked differently - never seen ailerons and elevators controlled by the same servo. Is that a new design. Also, the push rods must have "Z" bends at the point where the push rods connect to the clevis.

Rudder Direction is reversed. ?
