“Your slope just got a little smaller...”


The HP60 is not just a scaled-up version of its little brother. Instead of an overall embiggening of the planform, we spanned the 48" Halfpipe templates to 60", resulting in a higher aspect wing, with even less sweep at the trailing edge.

The HP60 comes with a monster, tapered carbon spar system (aka golf club shafts), coupled with a beefy, custom, pre-angled, 15" spar joiner made from T6-6061 aluminum, and with a 5" steel center... it is very likely one will never be broken. All combined, this is THE most torsionally rigid EPP wing we have ever felt, pre covering, and with excellent weight distribution. Depending on your intended use and building techniques, it can only get stiffer. While not shown in the below pics, the wings also come with pre-cored chambers for the provided lead balance weight, (8) 35 gram, 1" slugs.

We spent over 6 months developing a new molded tail mount system (below). It has an aerodynamically clean design, with a crisp, low-drag perimeter, and, while it is not "unbreakable", it will have to see a MAJOR impact to do it, which should save the rest of your plane from significant damage (unlike Bluto's old internal system). Utilizing square aluminum tubing, high impact urethane plastic, and a square, solid carbon fin boom, we are very happy with the integrity of this system. (Note: At some point in the near future, the below system will also be available separately here on the site, for replacement or modification to other kits). Given the speeds and energy in which this plane is intended, we opted to eliminate the rotational factor, or "safety net", that the 48" HP incorporates with the round carbon boom. Since the square carbon friction fits very snugly into the mount, it should also be easily replaceable, if broken. The balsa stock has been stepped-up to 3/16", versus the 1/8" on the littler HP. (As addressed in the manual, DS guys may want to reduce the fin planform area by about 30-50%, and potentially go split-fin, as with the Blutos, given the opposing flight loads; the stock tail config is more intended for heavy frontside loads).

This plane is intended strictly for medium to heavy air. If you only fly little pink "girly hills", please opt for another bird. In light conditions, on smaller slopes, you CAN get this plane to flick, if pushed too hard on a turn, in meager lift. It is simply the nature of a higher wing loading design, balanced with a slightly swept LE, to keep nose weight/mass distribution at the absolute minimum. In bigger air, on bigger slopes, this plane, honestly, rocks. It will grip and bite turns beautifully, with great energy--you just need a bit more air than the 48" version. Note: As with all of our aircraft, the HP60 is not intended as a first airplane.
