"My early designs like the SBD 100 were all about light weight stunt flyers. We used to compete in a "Flying Circus" of Beer can Bowling, Limbo, Loops in 5 minutes, Group Spot landing, and the last event was plane to plane combat. Since the planes were cruchies it was a exciting end to a good day of flying. The G-S-48 is built in the spirit of that kind of fun but with EPP." Steve Drake 

The  G-S-48 Sport Flyer

Just for the fun of free style slope soaring

This plane is a very clean looking and flying slope fun option. You can use it on lighter lift days. In average lift it is great for refining your inverted flight and slope pattern flying skills. Add the optional nose and an electric power system and fly it on no wind days or off flat ground. Designed for Slope stunt flying
Speed >> Agility >> Durability

Available as a plug on the G-ST - 48 fits into a suit case

In two minutes your ready to go

 

Optional nose for electric flight  comes with materials such as carbon and plywood and instructions.

Driving on vacation with one of the Gulp Travel designs in your suit case gives you a new view of paradise. One ridge + a little wind = a G-ST-48 toss

and another and another and another.........

Inspired by the The SBD 100 a light weight stunt slope plane I designed in 1984. We now can benefit from more durable EPP. The G-S-48 weighs in at 15 ounces. The G-ST-48 is 16.4 ounces.

I'm pretty excited to offer this plane. I have been mainly focused on racers but have wanted to address the things I like to have in a Slope Sport plane for my area with our typical 6 to 12 MPH wind.

My early designs like the SBD 100 were all about light stunt flyers. We used to compete in a "Flying Circus" of Beer can Bowling, Limbo, Loops in 5 minutes, Bottle cap spot landing, and the last event was plane to plane combat. Since the planes were cruchies it was a exciting end to a good day of flying. The G-S-48 is built in the spirit of that kind of fun but with EPP.

Here are the details.

The New G-S-48 is available for $95 - It is a very complete kit and I can supply an optional 2nd nose and instructions - $15, for those who wish to have a spare nose with motor for no wind days they can plug on.

Newest Travel Version the G-ST-48 completely comes apart for suitcase convenience $110 and it will accept the extra nose for Electric powered flight.

Features

A very light EPP design with carbon fiber reinforcement - for a great strength to weight ratio

High density grade EPP foam parts – for low twist and better impact strength

Removable nose cone - easy access to your radio gear any time.

Optimum gear would be HS 56 servos and a micro stamp Berg 4 channel receiver or one of the many similar sized dual conversion receivers for long range. AAA NIMH pack is optimum but it will accept a AA pack.

Low drag EPP fuse design The fuse profile is actually a NACA symmetrical airfoil

Pre-shaped with wing mount cut in – For easy and predictable building results

Fuselage pod 2.5” dia - Holds either 1000 mah lithium, AAA or AA packs

Low profile linkage plan for wing servo controls - reduces drag and potential damage

Quality EPP and balsa tail feathers – strong and light

Symmetrical airfoil for tail and elevator – for very low drag - No flat “Coracrap”

Full flying elevator - For maximum inverted flight efficiency and no visible linkage - The secret weapon to efficient inverted flight

Wing panels have the spar cavities precut – Easy to assemble wings

Extremely durable Carbon spars and spar joining system for a very strong wing  You won’t likely break this wing but that is not a dare J

Designed for Flapperon wing control -  allows you to slow the plane down and increase lift potential. Flying wings do not have this function.

Use your + and - Snap Flap elevator mixing - Adds to the inverted capability for stunts in moderate lift.

Detailed instructions with photos – Will introduce you at least one new building technique to use on other projects.

You still want more?

Electrify it? Ask for the 2nd special nose cone and get two ways to enjoy this plane. I will include a list of items to buy to setup the electric option with an Outrunner 450, folding prop with spinner, 3 cell lithium pack and speed controller. Swap noses, add a some tail weight and your in the air on those no wind mornings. Find a thermal and turn off the motor for some clean soaring fun at the all up weight of 22 ounces and still reasonable wing loading of 10.5 ounces per square foot of wing area.

Not a RTF plane but not hard to build – You get to assemble it to your taste. Admit it. Really nice things take a little time and effort. Learning something by completing small projects is truly part of the fun of this hobby. Need help, just e-mail me. Cheers, Steve
