Lego Creator – Twinblade Adventures (31020) Review


Lego Creator – Twinblade Adventures (31020): Another 3-in-1 from the Creator series, but I’m not as enthralled with this one (even among those with winged vehicles) I’ve always said my main peeve with Lego sets are those without a clear audience. This lacks any cool factor, historical factor, or engineering factor – it feels more like it exists because they needed some more aerial Creator sets.

What Else? So while it’s clear without any sense of motion – the plane offered here has no way to maintain, and would as Toy Story put it ‘fall with style’. Undeterred though I set out to see how possible it would be if this was mechanized. Where my little push of velocity was a constant it could maintain.

Of course NASA is kind enough to provide formulas and understanding on the topic of Lift. Most of this equation is easy enough to figure out, weight, air density, surface area of wings. Of course there was one wrinkle – namely the Coefficient of lift.

Now while NASA does provide info on this, sadly in order to calculate it – you need a wind tunnel. Which as mentioned before I do not have (although maybe I should invest). Now using a nifty calculator (and Worcester’s current temperature) I get a required CL of 51571.41 (which checks out doing the reverse math).

Now sadly I am not an aeronautics expert – so I can’t say whether 51k is a lot or a little, but especially with no motor – it would seem Lego planes were simply not meant to fly.

(For those wondering that comes from 1.068 N for weight from grams of 109g, 7 inch^2 for wing area, 0.284 ft/s from a simple push test, and this chart for air density.)

Of course I am a computer programmer reviewing Lego sets – so I welcome others to correct my math here.


Remix: For the remix here, with the past fourth of July, and the return of Battlebots I figured it was good of me to make a little bot myself. (Okay I admit I was watching it during review) Due to the needs to get all the ramps, flippers, and horizontal spinners it does suffer from a bit of rainbow-warriorism though.



Final Thoughts: Overall this is my least favorite from the Creator line, and it’s not hard to see why. The color palette is rather drab, each of the creations just doesn’t feel as ‘tight’ as other creator series sets, and I wish the sets were a bit more complex and minifig scaled.

Final Score: 1 out of 5 Stars

Lego Creator – Power Mech (31007) Review


Lego Creator – Power Mech (31007): Perhaps its the nature of the other Creator series I’ve done, but I am actually a bit nonplussed about how in all the other of the series – there is often 1 build which uses all the pieces, and another 2 which are more subsets. Here however even the big mech build leaves behind more than a dozen or 2 pieces. On the other hand though I am actually a big fan of how the mech works and comes together.


Time to Knoll: 13 Minutes


Time to Build: 19 Minutes (Mech)


11.5 Minutes (Helicopter)


14.5 Minutes (Truck)

What Else?

To be fair I sort of see where the model was coming from – in short it’s trying to bank in on the Transformer appeal – the problem being that there are parts in all 3 types which are just not used in the other models. If you are looking for a real Transformer, check out this creation from Boyzwiththemosttoyz(about 1 minute in to see the transformation)

This is the sort of thing I wish Lego would do more of – they’ve proven very good at moveable parts, and I feel like their aversion is legal-based. However the above is only a single example of people making Lego transformers. I urge you to just take a look at MoCPages category page as there is just a bunch of great builds.


Remix: Well with all the nice green here my mind drifted of course to space. So at the need for wheels and limbs, and it was clear I was going to make a rover. Best of all I was able to use all the pieces in the model – and I only needed a common black circle axle – keeping well within my 5 rule.



Final Thoughts: I feel this is more (especially with the current sale) a step to get some nice green pieces, some good limbs and bending parts – and the weird and rare corner 2×2 plate. While I do like the mech, the other builds feel kinda more tacked on as compared to other Creator builds, and I wish Lego had just release the mech on it’s own.

Final Score: 2 out of 5 Stars
