Curious... FT Power Packs? Like a PP-B (Pack B Includes 2 ESC's BLHeli 20A w/XT-60 connectors, 2 Motors Emax 2213-935, 4 Props 2-10X4.5/2-9X4.5 CW&CCW, 6 Emax ES08AII 9 gram servos, 1 Y-power lead XT-60 connectors, 4 20 cm servo extensions, set of linkage stoppers, Allen wrench and screw driver. Pack B $85.00
Or the FT Power Pack C, made for the FT Guinea Pig (1473 mm wingspan) for $10 more.
That's a matter of purpose really. There is a big enough weight and power difference between them that they don't always interchange. one of my current projects I'm using the C=pack twin as the plane is a bomber with a lot of surface, I know it can carry the weight well. but there are other planes that are pushing their weight capacity at a B-pack. A C will work, but it would have to be fast. (which doesn't always work well. (look at the old fogey) The wing isn't build for that kind of speed. (I'm sure folks have done it and had fun, but I hope you see my point.)
As I expand my fleet and motor sizes... I see that each one has a spot. (from Gremlin Quad motors, through A and Fs up through E and those GIANT agricultural quad motors.) Same with the EDFs.
30-50-64-70-80-90mm sizes, perform Very differently.
I'm excited to see where the Tachyon's fit, performance wise.
I wonder if the power packs should be labelled some other way.
@GMalatrasi - The build is coming along nicely, keep up the good work! I've heard that about the black foam board too. (I have two sheet set aside for a F-117 Stealth fighter build) It is likely the original formula. The original DTFB was pretty easy to pull off. My nickels worth - Just make sure to glue hinges and edges.
