Hi all,
I am a beginner. I have clocked 70 hours in realflight G4.5 flight simulator using FUTABA 7C. I can even land mustang P-51 elegantly  Smiley in the simulator, i am mentioning this as it took quite a time to learn that. I am planing to build http://www.armadamodels.co.uk/models/ctd_electric_delta_ma01a.pdf   Ceiling tile delta (CTD). As it seems less complex to build & slow flying capability.

Following is the materials i have bought to start,
700 kv motor-reason is the CTD builder uses reduction gear box. So i bought less RPM motor
1000 mah LIPO battery
9 gm turnigy servos
5 mm biofoam sheet
8030 propeller


I have made motor mount today using aluminum L channel. Picture is enclosed in here.

Please help me in the following,
1. how to get push rods for servo to control surfaces
2. do i really need propeller saver?. if i do not fit one will me planes' nose break while landing as the propeller i bought seems stiff. Do i have to fit landing gear to solve it?.

advance thanks for your time & response.

Regards,
R.BALAJI

Balaji,

You'll need to cover those bullet connectors with heat shrinks for proper insulation or you might risk burning-out the setup.
Which motor and ESC are you using?

Push rods can be made using bicycle spokes, umbrella spokes, gel refills, bamboo skewers etc. There are a lot of tutorials/ videos available. Just search.

A propeller saver is not needed if you are using a good landing gear or landing on tall grass.

hi swapnil,
i am using Turnigy DST 700 brushless motor & Hobby king 30A ESC. I test ran this setup with receiver. Worked good. Even i tested whole electric setup in delta configuration using servos. it worked well.

The DST 700 won't give you enough thrust with a 8x3 prop on a 3s LiPo. And do cover the bullet connectors properly for safety.

Insulation tape is okay but still risky. If possible, go for heat shrink.

Check the propeller thrust chart of your motor. You'll at least need a 10x4 with that setup.

Hi all,
today i made servo mounts. also i cut bio foam in delta shape. i mounted the servos in a scrap bio foam. photos of the same is attached herewith. am i adding extra weight by these mounts?. even the motor mount seams heavy which was made from 3mm thick 1.5" L aluminum channel. i hope i do not end up with a model heavy to fly.

Regards,
RB

@balajir: Correct me if I'm wrong. It seems you had made certain changes to the original design. There are two vertical stabs as well the design is also quite different. Any particular reason for this?
But, I'll have to say very clean and tidy job.

hi all,
finished my delta wing. ended up with 450 gm total weight. wing span is 1 m. please tell me is it too heavy to fly. going to use 8X4 propellers. only battery is to be fixed, which will be done in the field with the help of experienced flyers.

Thanks in advance. photos are attached herewith.

Regards,
R.BALAJI

He was extremely polite, and was enquiring regarding flying field in Delhi.

I don't understand why you ask, or why you have these weird pictures in the reply. In any case, I fail to see what it has to do with you

Balaji, give me a call on Thursday or Friday, and we will fix something.

Are you off on Saturdays?

Have you contacted flyers in Mundka field, Delhi?
