patrick. you will find an "Albums" tab at the top. You have to create an album of your pics - then you can add them to your post.

great work!

[New 78" Vulcan for twin 90mm DF]

i can't remember if you said you measured your wingspan? Ours have all come out to 83"

[New 78" Vulcan for twin 90mm DF]

very impressive! I love your finish. I used the CG as per the plan and it worked out fine.

[New 78" Vulcan for twin 90mm DF]

looks good!

[New 78" Vulcan for twin 90mm DF]

Time to get after it Craig! People are waiting

[New 78" Vulcan for twin 90mm DF]

loving it!

OOps - i see in your previous post that you are using 120A ESCs. Sorry for the confusion. But, easier hookup with the "Y" harness

[New 78" Vulcan for twin 90mm DF]

Peter - the usual way to achieve multiple hookup is to use a "y" harness easily available from H King and many sources for less than $10. I will point out that my motors each draw close to 100A at full power on 10s so you might want to rethink your Turnigy 60. I am using Castle 120HV.

[New 78" Vulcan for twin 90mm DF]

doing a fine job. Did you mention what you are using for power. I am running 10s on each side and i found that i needed to put the 6s packs fully aft and the 4 s packs fwd to balance. Mine turned out a bit nose heavy. That's with the receiver and one 6 cell rcvr battery aft and one 6 cell receiver battery and the gyro fwd. I think i've got about 40 ft of wiring in mine!

Martin - I don't know who you were asking but i am using Jet Fan 90s with HET motors on 10s. (9 blade)

[New 78" Vulcan for twin 90mm DF]

I too had to do it like Craig said - in pieces. The other way just wouldn't work for me. That done - i kept looking at those flat "air dams" next to the fans and, well you know the rest. Probably uneeded.

[New 78" Vulcan for twin 90mm DF]

Looking good. I became worried that the flat bulkhead next to the fan intake would reduce efficiency and power so decided to fair in the inlets to the fan. Seemed like a good idea and my thrust measurements would agree

[New 78" Vulcan for twin 90mm DF]

that's how to do it!

[New 78" Vulcan for twin 90mm DF]

Good work Peter. BTW , have you measured the wingspan yet on your "78" Vulcan?

[New 78" Vulcan for twin 90mm DF]

looking good!

[New 78" Vulcan for twin 90mm DF]

Looking good! Instead of painting my nozzles , i used a silver sharpie pen to color them. Gives a kind of metalic, steel finish.

[New 78" Vulcan for twin 90mm DF]

Peter - you will be so glad you made it this way. Also helps immeasurably with routing the wiring. I believe i have about 35 ft of cabling in this model.

coming along nicely Peter

i posted an answer on the Groups page

[New 78" Vulcan for twin 90mm DF]

you will very happy that you put the battery hatch on top. Here's where i put in the esc air scoops

[New 78" Vulcan for twin 90mm DF]

[New 78" Vulcan for twin 90mm DF]

looking good! seems nice and straight. Here's where i was at that stage

[New 78" Vulcan for twin 90mm DF]

looking good Peter. Here's where i posted my build thread
