![]() If you find a used Rans S-4 and S-5 The Ultralight Flyer recommends that the plane’s fabric be tested, the airframe, wings, landing gear, and the control systems be thoroughly inspected. When equipped with the more powerful engines, climb comes in at 750 feet per minute.Ĭruise speed in S-4/5 is 55 to 60 miles per hour while stall, using optimal flaps, is 25 miles per hour.īoth S-4/5 are enclosed cockpit designs but can be flown with the doors removed (which all of we early ultralight pilots love).Įither model can be fitted with floats or skis and cabin heat and ventilation is available. They have a center-mounted stick and left-hand throttle.Īs Randy is a longtime fan of Rotax aircraft engines, power was supplied to S-4/5 by the single cylinder Rotax 277 at first followed by the more powerful, twin-cylinder 377 or 447 engines. “No special tools or jigs are required to build the planes and they can be built in a single car garage.”īoth Rans S-4 and S-5 feature standard stick-and-rudder three-axis controls with flaps. “Rans’ manuals and instructional building guides lead the industry in completeness,” expressed Dave. Kit assembly time for these fairly simple aircraft was between 100 and 125 hours. Most of Randy’s designs are high-wing, strut-braced, tractor aircraft, though a smaller number of models were pushers and one current model is the low-wing S-19 Ventura.īoth S-4 and S-5 featured the same bolt-and-rivet-joined aluminum tube construction, covered in sewn, slip-on Dacron sailcloth envelopes. The Rans line of ultralight aircraft were first introduced at Sun ‘n Fun 1983. Then and today, most Rans models have been made available in both tricycle gear and taildragger configurations. ![]() I have often told Randy how I admired the factory finish of the airplanes he presents to interested pilots at airshows.Ī stickler for getting it right, Randy demurs my admiration but anyone who has closely examined his models at an event knows I am not exaggerating. “The quality and finish of his aircraft and kits has to be seen to be appreciated,” Dave added. (If you prefer a handheld option, however, we recommend the Nathan SpeedDraw Plus Insulated Flask.“The founder of Rans Aircraft, Randy is one of the most prolific designers of ultralight, experimental and Light-Sport Aircraft that I know,” said Videoman Dave in his production of these ten vintage ultralight videos on his The Ultralight Flyer YouTube channel. Carrying one could cause soreness, cramping, and, over time, injury to the shoulder muscles (from modifying your arm swing) and forearm muscles (from gripping), and even hip, knee, or hamstring issues related to those upper-body form alterations. ![]() ![]() The lopsided weight and sloshing of a handheld water bottle-and the need to grip it-are more problematic. “The bottom line when it comes to extra gear is that has to completely disappear from the runners’ consciousness.” A phone armband might suffice, particularly if you use Bluetooth headphones-there’s no cord to one side that might cause unnatural neck or shoulder gripping-but if you feel any uneven soreness in those muscles after running with an armband, the armband could be affecting your form. “It’s not necessarily the weight of the, but rather the change in posture and behavior as a result of the runner’s awareness of that affects their run,” explained physical therapist Alice Holland in an email interview. (If you’d like a slightly larger belt that is built to withstand the elements a little better and to help facilitate more involved training, we like the SPIbelt Performance Series.) The SPIbelt Large Pocket also works with a belt extender (sold separately).Īrmbands and handhelds aren’t ideal if they cause you to alter your natural running form (nor is simply clutching your phone in your hand). And it keeps everything squeezed into one stretchy pocket, which means that if you need to pull something out mid-run, there’s a chance other things might fall out, too. The pocket’s synthetic fabric wicks sweat well, which should keep you cooler, but it isn’t water resistant-contents can get a bit soggy. You can adjust the belt from about 25 to 47 or more inches, and it has no annoying dangling straps, unlike many such pouch-on-a-strap-style belts. With the adjustable band tightened snugly, it doesn’t bounce during runs. The single stretch-fabric pocket can hold a large phone (the SPIbelt website says that includes an iPhone 12 Pro Max or a Galaxy Note 20 Ultra), cards, and keys. If you’re looking for a convenient, comfortable, affordable way to bring must-haves with you on everyday runs, the SPIbelt Large Pocket is it.
