hi  subbu

in the 4th n 5th pictures the fuse and tail surfaces look slight bend  :headscratch: or this is a photo effect

what is the weight of the model now ?


Title: Re: Blu-Baby 24 inch aileron version build log
Post by: sahilkit on October 15, 2009, 11:57:55 AM
update,wing is done and the servo centers at 1460usec or 1.46msec with little upward angle in both the aileron half's

hey you don't have to say sorry and what power setup are you planing to use also what is the bead size of the thermocole you are using ?? (1mm - 2.5 mm dia)



Title: Re: Blu-Baby 24 inch aileron version build log
Post by: sahilkit on October 15, 2009, 02:46:12 PM
here's my spec

Power setup

motor: 10gram 1811-2000 brushless motor from hobbycity
prop: GWS 5X3 orange propeller
battery: Hyperion 2S 400mah
ESC: turnigy-plush 10A

the motor prop combo is suppose to produce 130grams of thrust at 3amps draw 2S

expecting the auw to be under 90 grams !

i could fly nine of your blu-babies with my motor

Post by: sahilkit on October 15, 2009, 04:25:30 PM
hi subbu just make sure the model is upto it

update, building landing gear  ;D guys i was thinking of using rubber band to hold the landing gear to fuse what do you people think ???




Title: Re: Blu-Baby 24 inch aileron version build log
Post by: anwar on October 15, 2009, 06:34:57 PM
Isn't it better to use something like cycle spokes to build the landing gear, to conserve weight ?

Post by: Pikle6 on October 16, 2009, 07:25:21 PM
hi subbu just make sure the model is upto it

you said it right

the tremendous power from my motor and the lack of reinforcement on the wing lead to the flex in the wing which ultimately gave way and one wing half just came out well the plane flew well anyways

hey guys i just finished fixing it and it glides as it used to be but i have added another 100gms of reinforcement on the wing and body to handle the pressure and it seems to work

Why not couple of CF rods, aluminium rods, kabab sticks etc ?  This is one heck of a reinforcement  ;D

Subbu,
   That CF flat strip along the fuse should be placed perpendicular to the length of the fuse so that the fuse will not flex. The way you have placed it there can still be flex of the fuse. The plane looks just like a warbird thats already been shot down several times  :D
