AIRBORNEIn preparation for this review, I haveflown over 100 flights with three differ- ent Tipsies. I have used them to teacha middle-school class about flying,taught beginners at our club field, and The stabilizer tips are delicate, and I put a cardboard fixture on the side of the box to loops, barrel rolls, stall turns, and other doesn’t touch anything. With the lithium batteries (that don’t self-discharge quickly) I just keep the model in its box in the trunk of my car, ready to fly at any time, even if it hasn’t been charged for a month or two. The Batteries America BP-LI8412 lithium fits and balances perfectly in the Tipsy, the connec- tors are already wired, and their matching fool-proof. This is a no-worry lithium setup.

1. The modeler must solder the motor controller to the motor and solder the three blue capacitors (supplied) as shown. 2. The front of the wing uses a ply- wood mechanical hold-down that allows the wing to easily rotate sideways on any impact. On a straight-ahead impact, the back of the wing rises up. Using magnets in back instead of the provided bolt lessens or prevents damage. 3. Two holes are made near the trailing edge of the wing to fit 3/16 diameter by 1/8 in. thick neodymium magnets. I just press the magnets lightly into the foam to create circles, and then open up the holes carefully to a depth of 1/8 in. with a hobby knife. After making sure the holes are the right depth, the magnets are epoxied flush to the surface. 4. If you use magnets to hold on the wing, this leaves a hole in the bottom of the fuselage where the wing bolt used to go. You can choose to cover this hole with tape or, if you wish, make it a little larger and put in a ¾ in. wheel for landing on concrete or asphalt surfaces without tearing up the bottom of the plane — which you should protect with some pack- TYPE: Trainer, park flyer, sport flyer, slopesoarer, and thermal electric soarer RADIO: Hitec Feather receiver, Hitec HS-55 servos ALTERNATE RADIO SYSTEM: GWS 4-channel receiver, Hitec HS-50 servos POWER SYSTEM: Graupner 280 6Vmotor motor, Graupner folding CAM4.7x2.3 (12 cm x 6 cm ) propeller, GWS control (excellent for Lithiums because of its appropriate cutoff voltage), Batteries battery (this has been replaced with lighter, Li-Poly battery options for the Tipsy.

It flies well and is an easily-assembled, well-designed model that fea-tures advanced foam molding technolo-gy. It is my first choice for teachingbeginners, yet I enjoy flying it myself in awide variety of situations and wind condi-tions. It will sustain powered flight forover half an hour using NiMH batteriesa n d f o r m u c h l o n g e r p e r i o d s u s i n gLithium batteries. It can be built in aboutfive hours.
When pressed into the fuselage, the magnets doubled up on the wing leave small impressions in the foam. Be sure to install the magnets so that they are attracted to the magnets in the wing.
Use epoxy and put a small piece of scrap polyethelene plastic (the kind used for vegetable bags in groceries) across the mag- nets. Then put the wing in place while the epoxy hardens. When the epoxy is hard, the polyethelene will come off easily. The wing will not come off in the air, even if you loop and spin the don’t go Lithium) the 7-cell720mAh battery that HobbyLobby recommends.

Note that the fin has also been sanded and the molding mark has been filled with light weight spackling compound (optional).
The plane will fly fine without this bit of refinement.
