Description

The Hot Shot 2 is a well regarded glass and carbon electric 1.5m DLG with a flying weight of about 370g. The Hot shot is very tough and easy to fly, making it a great F5K trainer. The model uses solid molded DLG construction methods, and a modern Drela airfoil, which keeps it light and gives it excellent performance.

The Hotshot 2 is based on the Longshot DLG with excellent aerodynamics and a nice molded glass / foam / glass wing, with lots of carbon in the right places. The Hotshot’s fuselage is a glass molding with a lightweight rolled carbon tailboom. The R/C is accessed though a handy canopy hatch, and the wings are bolted onto the low pod, keeping the frontal area to a minimum. The pod is supplied with the nosecone in place, and a 32mm firewall is supplied. However a smaller recessed firewall could alternatively be fitted allowing one of our modern lightweight 25mm F5K powertrains to be used. Thus the modeller has total flexibility about motor choices. The tail and fin are lightweight balsa surfaces that will need a little shaping and covering in film. The tailplane is conveniently removable for easy transportation. It is mounted on a prefabricated pylon that is glued to the boom. The Hotshot’s very smooth low drag wing is supplied in two pieces and is easily joined using the supplied carbon reinforcements, and is painted with flashes of colour on the tips. All the linkages are provided, only glue, powertrain and the RC gear needs to be supplied by the builder.

The easy build, benevolent flying characteristics, and tough construction all make the Hotshot an excellent introduction to F5J type electric gliders. See some build photos of the very similar Longshot DLG here.

Hot Shot 2 Flying Review

Final flying weight was just under 350g with a 1100mAh LiPo battery. Been out half a dozen times on the slope despite the winter weather in sub 10mpg winds and very pleased.
Yesterday out in a northerly that was forecast to be 10mph with thermals, but was in fact over 20pmh most of the time with white fluffy clouds so mega lift. Lost sight of it 3 times and had to emergency descend. Loops, near axial rolls, stall turns, bunts, inverted (sort of) and good penetration in a +20mph wind.
Set up:-
• ADH330S (21g) motor driving 6x4 prop produces 250g thrust for about 6 mins
• 2 x KST X06 servos for spring and pull to rudder / elevator running in Hyperflight’s PTFE tubes located up front as close to the motor as possible
• Hyperflight’s 11A ESC (2g) no BEC so you can monitor the actual 2S voltage located under the servos
• 1100mAh LiPo battery 11x23x90mm (often used by Airsoft guns)
• FrSky Rx under the wing with antenna exiting either side for fuz
• 2 x KST X08 servos for elevators in wing with a compression contact wing connector
• Fin attached to boom in traditional DLG fashion with a slot / fiberglass / epoxy and a small stub below the boom (rather than the carbon pins in the kit)

Overall very pleased with the end result. Looking forward to the summer on the slope.

I found more details on the Horejsi.cz web site that show how they expect it to be built.
Build sketch https://horejsi.cz/DataFiles/1606_HS2/HS2_vykres.gif
Build photos https://horejsi.cz/PhotoGallery/1606_hotshot2/HS_sequence_CZ.htm

The build phots shows the servo pockets in the wing behind the main spar, whereas mine are in front like the Longshot. My balsa tail feathers were pre sanded and didn’t need any sanding. Nice balsa. Wings excellent with very thin trailing edge.

The build sketch shows the tail servos mounted under the tailplane with a 45g motor, 9x5 prop that results in a 500g flying weight. This isn’t exactly what I am after.

My objective is a lightweight slope model for those summer afternoons when you know there’s thermal activity. I am using the ADH330S (21g) motor, Hyperflight’s 11A ESC (2g) with a 6x4 prop and 2S stick 650mAh LiPo (31g) that produces 250g thrust for about 3 mins. I have the smallest KST servos mounted up front in the pod for the tailfeathers with a spring / string set up. This means the battery can be installed way back under the wing so you can adjust the C of G without adding lead. So far the target flying weight is 344g, but I expect it with creep up a little from there.
Overall pleased with the quality of the kit and enjoying the build. Looking forward to the summer.
