The author looks bit casual flying Summer Breeze Balloon Compared 60-powered plane balloon seems docilebut pilot needs stay alert keep spin ning around because its weightlessness Luthers latest project one-third-size copy Lous blimp gondola weight just 31/2 oz Smaller size good smaller rooms Luther Hux eei What looks hotair balloon really weather balloon liner filled helium covered sewn panels bright para chute nylon fabric Stripped servos suc cessfully power 4-in rubber model propel lers giving propor tional control same time Only surface has scratched relatively new kind RC flying will interesting see what future holds store us DURING Lous presentation Slow-Year Blimp Northern Virginia RC Club Building Contest stood line others try hand fascinating project years pondered fly RC indoors needing large hangar indoor Control Line experiments frustrated fast speed model blimp other hand gave time relax enjoy model no chance damage made wrong move Being inventor heart see doneand considered building own However number other projects started such Project Snapshot ParaCraft felt starting another would too costly time money Lou encouraged join him just wait Watching blimp shopping mall displays year always enticed build nonmodeling group finally caused give try During US presidential campaign came involved conventions delegates During planning sessions mentioned might able get blimp fly delegate congressional candidates look surprise everyone can get Blimp asked explained bit smaller indoor RC loved idea encouraged get Lou participate Unfortunately Lou committed other projects during convention season could fly us Since knew background RC asked would quickly build would cover cost helium Since big part expense 66 Model Aviation Joan Lou offered show build took job just three weeks before first con vention Lou spent evening giving details blimp planning start next night As sat considering begin aphotoofahot-airballooncaughtmyeye Instead copying Lous project exactly hot-air balloon Well almost hot airwith little help weather balloon would look like real thing Since Lou same show team difference would add variety began calculate size equivalent sphere compared blimp appeared 42-in diameter balloon would have enough lift fabric gearbut doors 42 inches wide plan use weather balloon liner provided escape Since balloon can inflated up 48 inches enough stretch left squeeze through normal door first constant fear breaking balloon has never happened yet drew up carboard pattern hot-knife cut parachute nylon panels outdoors forgot pay attention bias fabric first sewing attempt turned out like spiraled candy cane wife patiently removed stitching alternated bias pattern came out evenly later balloon cut straight fabric bias no further problem draping fabric over balloon check fit learned first big dont Dont tape anything balloon tape will etch rubber surface cause explode After comparing shape balloon blimp decided Lous two-step forward speed would work well balloon blimps long length helps turn smoothly motors switched fast slow round shape balloon could difficult steer unevenness power needed perfect use proportional system designed earlier blimp otherwise balloon might spend much its time spinning instead advancing forward proportional system does use separate battery receiver motors makes lighter Some felt good idea use same battery both actually healthy receiver battery drained motor battery would controllable either both systems have operated timed basis Neither Lou nor have problems watch charge/discharge time carefully did fail estimate power available would simply wait helium leak let model sink within reach usually less half-hour radio arrived week half before first convention started gondola looking light basket would look authen tic too heavy would no lift remaining banner ballast ready-made baskets Using hot-wire foam cutter cut h-in foam sheet sides gondola number coverings considered before settling brown burlap fabric seemed look like wicker attached foam box spray contact adhesive Other details could have added make scale-like weight would increase too much radio stripped plastic cases excess wire connectors cut overall weight ultra-light radio some stripping could eliminated weight still too much could go after plastic parts later two servos used power pod should miniature should about equal Kraft 14 15 Since have disassembled best choose radio system matches other radios way will have use extra gears pots plastic cases Also should check out burn radio before starting work radio can still repaired needed probably under guarantee buying new radio project would recommend consider Ace RC kits build up stage showninstead disassembling way described servo amps Hot-Stuffed side receiver board short direct wire connec tions soldered per original wiring feedback pot servo measured matching ohm -watt trim pot soldered Left Talk about being pushed out shapethe balloon takes

ParaCraft project Sept 1980 MA balloon job seemed simple cut out night stitched together next transmitter adjust servo trim pot until propellers stop turning Try command see props rotate correctly may have reverse leads both servo motors get correct response left turn right motor should thrust forward common problem learn ing fly balloon remembering reverse thrust down up up down replaced springs right-hand stick would easier stay between axis forward thrust Finally ready fill up helium make test flight freshly filled balloon should lift ballast least ten pennies will have remove time maintain zero weight during next couple hours four five complete fills 122 helium tank Since already some experience Lous blimp enjoying balloon within minutes wife Dawn quickly got hang began try challenges like landing hand etc Dawn flies RC parachutist show team does fly conventional-wing models have found people no flying experience can very well balloon very short time Precision landings still out immediate reach flying relatively easy next challenge getting through door no place go see what would happen Naturally 34-in front door stopped balloon simply pressing side feeding side past door jam short steps balloon outside few seconds Since helium-filled balloon could very easy lose attached several 3-oz weights lines wind could drag along couldnt lift balloon Out reach m back station wagon
