Title: build log : YAK 54 profile Post by: AEROVISHWA on July 07, 2011, 10:59:28 AM starting the thread for my new build a YAK 54 profile build
the difference in this plane is that it willl be built with PLY and no balsa. it will be powered with a OS .70 fl(4stroke) the cost of building is as low as :Rs:500 + extras (wheels tanks etc) here are some pics expert advice required: :salute: Title: Re: build log : YAK 54 profile Post by: spitfire on July 07, 2011, 11:14:44 AM What is thickness of ply you are using? Is it some spacial kind of ply?
Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 07, 2011, 11:58:45 AM its a ply locally available 2mm( they call it veneer) but its a ply grade
costs :Rs: 450 for 8ft*4ft. for one entire plane u need 2ft*4ft(for ribs and fuse sides) = around 110 for a plane the spars are timber costs :Rs: 3.5/ft (for 5mm*1inch) got it cut 5*5mm from a carpenter :salute: Title: Re: build log : YAK 54 profile Post by: spitfire on July 07, 2011, 12:15:22 PM That seems very nice deal to build structure in less than 500 bucks.
From where did you get plan for yak? Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 07, 2011, 12:54:51 PM the plan was downloaded form net and enlarged by a person in town. its his buizness he can print upto 80ft in length and 3ft in breath ( will give as much as u want )
bit costly fellow takes :Rs: 12/sqft so my plan alone costed :Rs: 180 Title: Re: build log : YAK 54 profile Post by: spitfire on July 07, 2011, 01:04:50 PM Thank for information. Best luck for build!
Title: Re: build log : YAK 54 profile Post by: bmanoj2 on July 07, 2011, 01:34:07 PM What covering filim you are going to use ? and please update once you check the CG.
Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 07, 2011, 02:12:08 PM will be covering it with vinyl cover. the plane is still in its building stage. as soon as it gets over will update on AUW and the CG issue

Title: Re: build log : YAK 54 profile Post by: PankajC on July 07, 2011, 11:26:11 PM the aerofoil looks fab.... using any software? I wish I had something to design such neat wings
Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 07, 2011, 11:31:56 PM thanks pankaj. its actually made from a plan got it online( mentioned above)
every thing in the entire assembly is hand cut by me. no machine, no CnC, no laser cutting. all cuts with fret saw. the holes with a 1.5" & 1" drill pic 1 : the tail plane with the elevators(not joined yet) pic 2 : the wing with alirons(not joined) pic 3 : the fin and rudder ( not joined) Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 09, 2011, 09:13:15 PM got the wing ready...!
the fuse was cut from 12mm ply( quite heavy) weighted around 500g when cut the holed to get it down to 300g...! found out the CG location = 10.52(with static margin 10%) wing joined waiting for arildite to dry..! :hatsoff: Title: Re: build log : YAK 54 profile Post by: spitfire on July 10, 2011, 01:05:55 AM If possible please post more detailed pics of how you are going to join wing to fuselage.
Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 21, 2011, 01:42:48 PM a bit change of plan...!
the fuse will be made of biofoam instead of the orignal ply...! reason: the ply was a bit of duffer quality and very heavy.. three sheets of 5mm biofoam stuck to make this fuse and will have doublers in the front section for engine mount... will post detailed pictures later..! Title: Re: build log : YAK 54 profile Post by: naatumach on July 21, 2011, 01:56:17 PM very elaborate.. good job sir...

Title: Re: build log : YAK 54 profile Post by: rcpilotacro on July 22, 2011, 01:10:37 PM Gr8 build vish. Keep throws bare min for maiden
Title: Re: build log : YAK 54 profile Post by: ujjwaana on July 22, 2011, 01:48:35 PM Nice progress Vish! Your build exhibits that scratch building could be done with so less resources!!
What power system are you planning to put ? If it is any where near to glow engine, do put two silver pine 'Longerons' from the the tail till the engine mount and put the landing gear on lower longeron. What about covering ? Sunfilm/Cellphene/Aluminium foil ? All the best for the rest of the build. Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 22, 2011, 01:51:42 PM two spars have gone running from the nose to the tail... more or engine bearers and doublers will be added soon and pics posted..!
Title: Re: build log : YAK 54 profile Post by: AEROVISHWA on July 22, 2011, 11:28:13 PM some pics of the doublers with the bearers
