A. Electronics:
A2212 1000kv
1045 propeller
30 Amp ESC
2 x 9 Gram Servo

B. Material:
5mm HD thermocol with fevicol water mixer.

C. Templates:
I can't get perfect template  :'(

D. Battery:
Please tell me about battery. Which battery is okay for ft old fogey. I mean capacity. :-\

Main focus on:
1). Weight.
2). Workmanship.
3). FINDING CG before installing electronics.
4). Light-Weight Landing Gear.
5). Less Glue from Glue Gun.
6). Use of more Ice Cream Sticks.
7). Baansh or BBQ Skewers for wings.

Please focus on D(battery) then comment or post.

B) not your cup of tea.
2) focus must be HERE.
Do you know the AUW ?

You're reposting stuff that were already asked, there is a search box here for a reason. There's a gazillion amount of old fogey stuff in rcindia including mine. When you repeatedly post the same stuff over and over again, it'll be messy.

Hope it wasn't aimed at me...
Ask the OP to search.

Okay this is a thread(or topic) of old fogey build not for asking batteries for a particular design.
THis build questions have one question that is of battery.
I will post my build images.
Please don't fight.

I will focus on workmanship.
I don't know meaning of AUW or what is AUW
tell me about AUW.

@taksh,
Why do you go on asking others?

If you type 'what is AUW' in Google, you'll get the answer

Thoda apna khud ka dum/dimag bhi lagao na  ;D

@K K Iyer
I think AUW is something different not related to RC. So, i asked.

Taksh ji,

AUW is All-Up-Weight that is maximum total weight of the aircraft with which you can get airborne (All air crews, passengers, fuel/batteries/passenger meals/baggage/cargo/coins aboard).

@taksh,
Which battery? Capacity?
Answers already given in the flitetest videos

Finding CG before installing electronics.
You don't have to FIND THE CG.
Balancing it without electronics is USELESS.

Please put in everything required to fly.
Then check if it balances level at the specified CG point.
If not, add weight to nose or tail as required, or move the lipo forward or back.

Aapke sawaalon se aksar aisa lagta hai ki aap bachchon ki tarah spoon feeding chahte hain.
Aisa impression kyon dete hain?
Aap to kafi jankaar hain.
Har choti baat pe sawaal na uthayen.
Thoda search kijiye, thoda dimag lagaiye.
Regards

Clarification/ assistance is good.
But spoon feeding is NOT good.
It prevents others from learning.
You deprived taksh of the opportunity to find out something by himself  ;D
Regards

@K K Iyer sir
I understand all things.
I will try to not ask something which is already posted.
I will search on rcindia before asking.

Spoon feeding  :rofl:
I don't know how this word come in posts. :giggle: :giggle:

Battery:
500mah 3s

Build Completed
Used 9g servo & paper clips as push rods.

Fuselage weight without servo is  190g
Wing weight is 110g
Battery weight : 46g
Total weight is more than 346g
I think 50% throttle is okay for my old fogey.

I want to fly plane but rain become a problem again.





prabal276

use full throttle. no harm.
show a picture of the Pushrods please......

taksh

DIY Control horns using card. (Made after watching Andrew Newton)
This time, control horns are best. In previous blue baby, I need to set limit in tx for servo stalling.
This time, only one servo with little stalling and set one end point to 90% from 100%.

Two things could have happened:
Eother you gave too large a control input
Or the wing polyhedral joint was not strong. The left polyhedreal clearly flexed and stalled.
The plane did fly though......
Keep working!

taksh

polyhedral portion was flexible.
In 1st maiden plane was going to left side but in 2nd maiden flight, plane was going in straight direction(sidha ja rah tha).
I gave small control to rudder.
I throw plane in wrong direction of wind --- 1st problem.
I know wing polyhedral portion is flexible --- 2nd problem.
People around me was disturbing me --- 3rd problem & most important problem.
Motor with no thrust angle...

Well actually no  thrust angle doesn't mean that plane won't fly good, crash or be uncontrollable. when thrust angle is zero and while flying you observe that when you get the throttle to zero, the plane either pitches up, down or yaws that would mean it has a wrong thrust angle.

If you don't want to continue with your old fogey then do a coro build, you can do the tiny trainer. Coro is tough it can resist good amount of crash. If you hot glue Coro in a wrong way then removing glue is also easy .

Also try without landing gear, sometimes it gets sketchy with landing gear...
