| hjlittman | Easy Built Heinkel 112 | Parked | 22-May-10 10:44 |  | | Views : 1261 | | Not exactly finished, but flyable which is all I need for the contest tomorow morning. If it survives the contest I will put the control surface lines and wheel wheel detial on it along with the exhause pipe and unit markings. |
| hjlittman | Easy Built Heinkel 112 | Build | 20-May-10 09:35 |  | | Views : 1297 | | A veritable orgy of covering. Working on the Heinkle and four other models at once. The Easy built instructions say you can can wet cover with the domestic tissue supplied. Well, sort of. Works on the fuselage if you are very careful. The wings threatened to become pretzles. Didn't even try on the tail pieces. Still looks like it'[s going to hit that 25 gram target weight without rubber. |
| hjlittman | Easy Built Heinkel 112 | Build | 14-May-10 13:13 |  | | Views : 1280 | | Two pin nose block key. I saw this type of nose block key used very effectively by some other modelers and tried it. Now it's about all I use. Former and nose plug are faced with 1/64 inch plywood. Pins are bamboo. Thrust button is Dare, not old style Guillow's thrust button supplied in kit. New style Guillow's thrust buttons are OK. |
| hjlittman | Easy Built Heinkel 112 | Build | 14-May-10 13:08 |  | | Views : 1258 | | Tacked together for obligatory "bones shot". This has a 24 inche wing span and 80 square inches of wing area. Even with all the extra gussets and braces it still weighs only 15 grams as seen. I estimate that covering, details and prop will add another 10 grams. |
| hjlittman | Easy Built Heinkel 112 | Build | 30-Apr-10 07:08 |  | | Views : 1263 | | Properly gulled wing. Uncovered, this whole wing half only weighs 2 grams even with the extra parts I added for strength. |
| hjlittman | Easy Built Heinkel 112 | Build | 30-Apr-10 07:06 |  | | Views : 853 | | This is a tricky thing to get straight. I will add some gussets to the fuselage frame and a center beam at the wing spar line to carry the loads through. I don't know how anyone building it right out of the box could keep it together long enough to get it trimmed out. |

| hjlittman | Easy Built Heinkel 112 | Build | 29-Apr-10 14:41 |  | | Views : 701 | | Now I have the wing tip up the right amount, The plans show a but joint at the wing break, but I added a lap joint in the spar and some gussets at the leading and trailing edges for reinforcement. The inboard rib is angled in, 1/8 inch according to the plans to get the downward angle of the inner wing panels, I traced the angle of the front view drawing and made a guage, |
| hjlittman | Easy Built Heinkel 112 | Build | 29-Apr-10 14:37 |  | | Views : 735 | | The plans say to prop up the wing tip 1-1/2 inches to get the gull wing effect. Glad that I checked before I took it of the board, Whoever drew it measured up from level in the front view, It is, indeed, 1-1/2 inches from level, but to get that dihedral from board level you have to prop up the wing tip to 3-3/4 inches. |
| hjlittman | Easy Built Heinkel 112 | Build | 29-Apr-10 14:34 |  | | Views : 730 | | Easy Built wood is light, in some areas too light. The 1/16 inch square stock was too fragile for the wing spars so I used some Guillow's wood for the spar. |
| hjlittman | Easy Built Heinkel 112 | Build | 29-Apr-10 14:32 |  | | Views : 803 | | Dealing with Easybuilt kits. The wings just glue onto the side of the fuselage so I added som more gluing surface. I am also moving the rear peg forward one bay to get balancing with less ballast. More than makes up for the shorter motor. |
| hjlittman | Easy Built Heinkel 112 | Build | 29-Apr-10 14:29 |  | | Views : 1582 | | Busy building board. The Heinkel is for a contest in May, the Blacksheep Squadron "Easybuilt, Beat Your Span" contest. The timing doesn't start until your model has flown the number of seconds equal to it's wingspan in inches. |
| hjlittman | Scratch Built Curtiss P6E | Build | 09-Apr-10 14:21 |  | | Views : 1303 | | Laser cut version is coming along too. |
