61 inch Boeing 747-300 electric ducted edition build log
plane dimensions = fuse length = 61 inches
wingspan = 51 inches
hey guys finally a bit of time to share about all the action thats going on here.
started this project after being inspired by an ex-747 pilot (my neighbour uncle)
first of hats off to brett jones for designing this plan as scale and good as possible
thank you
http://www.parkjets.com/747/well ok i have done a ton of mods but none to the basic model. the model as it is in the plans doesnot have polyhedral. other than that i have added landing gears plywood reinforcements and also the better edf mounts.
and yes all plywood attachments were done by 5-min epoxy. (very tough for an impatient guy like me.
electronics
servos - futaba standard ball bearing servos *4
sanwa standard servos * 4 = flaps and speed brakes
futaba standard one more for the massive landing gear retract which i one unique thing i designed
radio - sanwa/airtronics rds 8000 8 channel 2.4 ghz radio
battery pack - 2* turnigy 3s 11.1v 30c 2600 mAh lipo's
edf's - 70mm * 4 edfs
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7887had three so planning to use two of them here for the first test flight
for first flight the rest two pods will be left empty anyways the plans suggest the weight would be about 1.5 kgs but i am giving it extra power
after the first flight i will put in the rest two edf's which i have ordered from hobbycity for more scaleness
ESC's - 45 amp * 4
thats about all i am about to use here
build part I : wingfirst off decided to finish the wing as it would be finished faster
day 1 - finished building the tiled plan from 21 pages of a4 size paper
day 2 - finished the two wing halves with ribs and plywood supports
day 3 - today finished joining the two wings with plywood strips and epoxy
also today i ordered 5 sheets each of 2mm and 3mm depron from pune and will probably get them by tomorrow or day after
and will finish sheeting the wing to get the airfoil and just about finish the wing oh and also plot the flaps, speed brake and aileron servo position and possible hing everything
so looking forward to finish the wing by day -5
following are the pics which i took throughout the build process here they are
hope you like them and please suggest i need all of it i can get
and look at the last pic where the wing nearly dwarfs my electric guitar
