To be honest i already have too many big helis but a brand new in the box Goblin 700 Black Thunder T came up for a great price and I couldn't resist
The build spec will be:
Airframe: Goblin 700 Black Thunder T
Blades: SAB 690 Thunder main blades and 115mm tail blades
Motor: Scorpion HKII 4525 520KV 'Ultimate'
ESC: Hobbywing Platinum V4 130A HV
Servos: KST MS815 & 805 'Contactless'
FBL: Spirit Pro
The Black Thunder T is quite a bit lighter than previous Goblins. Weight saving comes mainly from the carbon parts. Boom canopy and frames are all from high modulus carbon and thinner, making these parts quite a bit lighter but just as strong. The Flipper landing gear saves a little weight too. I've seen reports of this heli build under 5Kg whish is very light for a hardcore 3D 700. I'd probably need lighter batteries to get anywhere near that weight.
The boxes:
I havent got the Spirit pro yet, I may borrow one off my Goblin 630 or I may buy another, we will see. The rest of it is all ready to go.
I made a start on the build. The Thunder uses the 'flipper' type landing gear similar to the speed. This can be a bit unstable on the Speed, but it's wider on the Thunder so I hope will be fine. The battery tray is all new and much improved. It's a 'slide in on rails' design retained by a latch:
Drive-train is standard Goblin 700 two stage reduction, belt primary gear secondary:
And all together:
I'll keep the photos coming as it takes shape.
