Wart Hog

AEROTECH Model #89018

Description

Not exactly an aerodynamic beauty, but it’s a lot of fun to build and fly. Wart-hog borrows design features from a number of missiles and research rockets to give a “special” look. Finish the way you see it here or use the multitude of decals to reflect your own unique style.

Build History

• 08/27/2002 – Purchased Aerotech #89018 model from Discount Hobby Center for $47.95 (Retail $69.95).
• 08/28/2002 – Took pictures of box and components. Scanned decal. Copied alignment guide. Cut slots from body tube for fins and launch lugs.
• 08/29/2002 – Did not build the motor adapter. Already have enough from previous models.Started building the motor tube assembly. Measured 4-5/8″ from back of motor tube and cut a 1/4″ slot for the motor hook. Measured 2-15/16″ from back for forward fin lok and 7/8″ from back of tube for the back fin lok. Epoxied the thrust ring to the thrust ring flanke and allowed to dry overnight. Checked fin alignment into fin loks.
• 09/01/2002 – Epoxied thrust ring inside engine mount. Epoxied fin loks to engine mount. Cut 1/4″ slits in forward end of engine tube at 990 degree. Epoxied middle adapter ring to forward end of fin lok. Inserted baffle into forward end of motor tube. Epoxied adapter to forward end of motor tube then epoxied baffle adapter into end of motor tube.
• 09/02/2002 – Inserted shock cord into eye screw in baffle and tied it to the eye screw. Inserted engine tube into body tube aligning fin slots with slots in body tube. Epoxied rings to body tube.One ring was even with front of tube and other ring was even with forward edge of fin slots. Used Elmers Yellow Glue to attach ring to body tube.
• 09/04/2002 – Traced fin on page 6 of book #2 and added measurements. Epoxied fins to fin loks, epoxied ends of fin lok and epoxied rear end disk into body tube. Epoxy filleted 2 of 4 fins. Cut one of conduit pieces to a 16-11/16″ length and epoxied in place using marks made from marking guide. Held piece in place with 1/2″ masking tape.
• 09/05/2002 – Cut second conduit to same length and epoxied it in place. Used masking tape to hold it in place. Cut third conduit to same length and sanded it to fit between upper ring and fin front edge. Epoxied conduit to body tube and held it in place with masking tape.
• 09/06/2002 – Cut the final conduit and sanded it to fit between fin and upper ring. Epoxied and held in place with masking tape. Epoxied launch lug into slots provided in body tube.
• 09/09/2002 – Epoxied two fin/tube contact areas and extended it along the conduit until the epoxy ran out.
• 09/11/2002 – Mixed remaining 2 ton epoxy in a 10 mL plastic disposable cup with end of long Q-tip. Cut a disposible plastic pipette and used it to fillet 2 more fin/body and conduit/body tube joints.
• 09/12/2002 – Epoxied 2 fin conduit/body tube joints.
• 09/13/2002 – Epoxied 4 conduit/body tube joints and 2 fin/body tube joints.
• 09/14/2002 – Epoxied conduit/body tube joints for the last piece.
• 10/11/2003 – Took model outside to prepare for sanding when a tip from emrr suggested the channel holes at the forward end of the rocket be filled to help the model fly better. The holes would create drag and rip off the channels if no filled. Therefore no farther work will be done on this model until the channels are filled and the adhesive has cured correctly. Holes were filled later in the evening with epoxy. It took several attempts to fill all the holes.
• 07/28/2004 – Sanded nose cone with 400 grit sandpaper and then 600 grit sandpaper. Wiped it down with dry rag and then damp sponge. When dry spray painted it with Krylon Gloss White. Sanded body with 400 grit sandpaper and dry wiped it with a rag.
• 09/20/2004 – Spray painted all but nose cone Krylon Gloss White.
