Human Alliance Bumblebee Leg Mod (Version 1.5)

Human Alliance Bumblebee (Leg Mod)

(As the previous link suggests, this modification proved to be very popular when originally posted, so much that many other artists decided to take their hand with it, adding other spins to it. Razerwire's addition not only clarifies some things from len_d69's tutorial, but also gives a different look at the modification itself. Also, other artists' contributions are included in "Version 1.5" here. ~Superquad7)

I rotate the legs at the hip joint first.

Take the parts apart and put them back so they look like this:

Make sure before you put everything back together that the hip joint has the more rounded side facing downwards.

If the mod is done and it is transformed correctly there isn't an issue but for the life of me every time I transform the thing I forget how to do it

If you do this mod, the leg transformation becomes a LOT more difficult.

From car mode, you have to unfold the thighs from the rest of the rear, then spin the thighs 180 degrees around on their hip joints (so the screws facing upward now face downward). Push the hip kibble so it covers the thighs, facing upwards. THEN, you have to figure out a way to turn the waist around without getting hip kibble or the thigh itself stuck in the roof.

Remember RiD Sideburn/CR Speedbreaker, and that ridiculous front bumper/arm mess? This is almost exactly like that. That alone is sufficient justification for Hasbro simplifying the transformation, via creative re-assembly (since they obviously wouldn't have the time/budget for a mold fix).

The easiest way I've found to do the waist rotation is to:

0.) Orient your "left" and "right" from the angle of looking downwards through the roof. This is to avoid confusion regarding which leg is "left" and "right", since you can describe them from the robot's POV, or yours. Let's stick with yours.

1.) Bend the *right* thigh at the hip 90 degrees downwards, away from the roof. Also give the lower (not-yet-transformed) leg a 90 degree twist to keep it from hitting stuff.

2.) Turn the waist counter-clockwise 90 degrees.

3.) Bend the right thigh back upwards, so it's straight and parallel with the other leg.

4.) Finish the waist rotation.

5.) Finish transforming the lower legs in the usual manner.

Remember that all of this comes AFTER you've twisted the thighs around, so the hip kibble faces upward (and screws downward).

If the window's plastic, or the hips are trimmed down just a bit, enough clearance should be given, and should eliminate the gap. I don't have him in front of me right now, but as soon as I do, I think I shall be tackling that.

After the mod, they need a 180 rotation and a leg swap.

Any further mod to put the thighs in a 100% accurate configuration would indeed result in an untransformable toy.

So they are upside-down in both cases. But I'll venture to say that they look more accurate to me after the mod. The wheel wells are supposed to point to the outside. They point inside before the mod, outside after the mod.

Unmodded: upside-down and wheel wells facing the wrong way.
Modded: upside-down and wheel wells facing the right way.

I agree here - those parts to be shaved aren't touching or rubbing against anything in car mode. There's a huge gap between them and the waist, shaving wouldn't do any good.

I don't think that's the solution. I agree about the waist just being a hair lower now - it could probably be fixed by enlarging the hole the waist post swivels in a little, but that could lead to a loose waist swivel.

The gap is minimal, so thankfully I don't really care.

The other bad point with the mod is that since the leg support is reverted (it faces down), the legs are not as high as they are in the normal mode.

It makes bumblebee taller and "thiner".

So well, as said before, it's 50/50. I guess the prototype just has different upper legs, there's nothing we can do to fix it sadly. They didn't just swapped the legs, they also slightly modified the mold.
