hi,I am a beginner, so can any tell me if I can use the following gear for a 24" blue baby-
Motor-1700kv
ESC-12A
Prop-60x30
battery-650mAH,3 cell.
If not please suggest the best for it.

A 1700kv motor with a 6x3 prop is not meant for trainer airplanes like Blu-Baby.

Motor kv for it should be in the range of 1100kv to 1300kv and something like a 9X4.7 sf prop.

so,can Iuse this motor?

EMax GT2210/13

Shaft diameter: 4 mm.
Shaft Length: 15.5 mm
Max thrust: 970 g.
Recommended model weight: 500 - 800 g.
Recommended Propeller: APC-SF 9x4.7 or Equivalent Propeller (3S LiPo)

Includes:
Motor

Spinner Type Prop Adaptor
Motor Mount
3.5mm gold connectors.

This is a pic of GT2210.

and I am thinking to use 20c 1000mah or 20c 800mah.

Well, I feel that a 204 watt motor would be an overkill for Blu-Baby. Look for something like 120-150 watts. This is just my opinion but do wait for the expert opinions on this.

100 to 110 watts would be enough with a9x4.7 sf prop  or a 8043 and  1300 mah 3s lipo
i suggest the best motor for it willl be a fc 2812

thank you

so now i am using
fc 2812 motor    1534kv
prop 7x4
battery 20c 1300mAh-3cell 11.1
ECS 7A
are these ok?

go for a 10 amp preferably 15-18 amp...dont use 8 amp

in that case I will EMAX ESC 18A

can we use cycle spokes for reinforcement?

spokes  are not a very good reinforcement.  (even i thought of using !!)
as they easily  bend & are just 1 feet in length

try using  thin 3*3mm wooden strips .....                 

better wait till some senior answers !!

Carbon fiber rods are available now at LHS. Spokes bend easily, not good for reinforcements

Yes carbon fibre is the best option available.

what is lhs?

See if this suits your requirements - http://www.rcindia.org/for-sale/hk-7x-2-4ghz-7ch-tx-rx-v2-%28mode-1%29-for-sale/

rchobbyaddict.com             new one  Rs.3250   
least i could find         

Is this a good radio???

HK6DF 2.4Ghz FHSS 6Ch Tx & Rx (Mode 2)

Well, it depends on your budget. If your budget is around 3.5k then you don't have much options.

what does k stand for?

k stands for 1000. So 3.5k = 3.5X1000=3500

are there any better radios for 3k
