Excellent competition level F5J/LMR or ALES Slectric Sailplane

From Esprit...

One of the most impressive European made sailplanes that we have ever seen. The brand new competition F5J/ALES Element 3.5E flies as good as it looks. Gentle, smooth, and very long flights are the standards for this beauty. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction. The entire model is constructed using free-flight techniques. Top Model uses the latest construction techniques such as CNC milling and laser cutting. The wings as well as horizontal and vertical tail parts are all classic balsa with Carbon Fiber main spare and leading edge design. The fuselage is gel-coated fiberglass with white finish and CF canopy. Whole model is covered with Ultracote. All control surfaces are hinged with adhesive tape. This fully built sailplane needs only basic assembly and motor/radio installation. The 3-piece wing and full flying stabilizer are each easily removable for transport and storage. Each part is carefully hand-crafted with meticulous attention to detail. Value is simply incredible.

Specs

  • Wingspan:137.75" (3500mm)
  • Length:71" (1800mm)
  • Weight:4.75-5 lbs. (2155-2300g)

Umm, 2008 called and they want their LMR ships back?

It's a nice price for a Full house electric ARF, but it seems to be optimized for a category of competition that expired years ago, specifically LMR.

At 2.1-2.3Kg, it's quite heavy compared to either the low-dollar Balsa kits (like the 2.9m Hoellein Inside F5J @1.1Kg) or the higher-end molded F5J ships (at anywhere from 1.1Kg-1.5Kg), requires a more expensive power system (specifically a monster ESC, with a 70A spec'd, and a huge 3S 3300 battery compared to the typical 3S 850-1300mAh now in common use).

For not much more you can get into something like a K3600 which will use a much less expensive power system and build up much lighter. Fully-built, a K3600 should be just about the same price (what you pay extra on the airframe will be saved in ESC & batteries)

Still circling in sink...
TopModel seems to overstate their weights. it should build out lighter. But even if it builds out at 1.7 or 1.8 kg, it's going to be a bit on the heavy side.

If it's a half kilo difference, that's a huge deal in terms of what you need in power system and how competitive it is. At the listed weight, I wouldn't even look at it (especially since the slightly lighter Samsara can be had for 2/3rds the cost), but at 1.8Kg and $175 cheaper than a K3600, it's a bit of a different set of tradeoffs. I'd still probably take the K3600, but there would be a definite argument in favour of the cheaper choice.
