| Then mark one end at 1/4" and carefully make a small slot for end of motor hook... |
...And glue the engine blocks on that end. Don't block the cuts... |

| Next lets build the motor mount tubes. First mark both ends at 1/2"... |
| Install the motor hooks in the slots, line them up and wrap twice with masking tape. |
| Line up the centering rings even and level with 1/2" marks on both ends... |
| And glue them on. I use Titebond II, it holds F39T reloads. Take 24mm MMT... |
| ...so the cord's not getting messed up while you install MMT even with the body tube. |
| Then install the 18mm motor mount tube... |
| ...or two... |
| ...or why not three for a Super Duper Hyper Viper... |
| Time to cut the launch lugs off 5/16" brass. I like brass, it's old school like balsa nose cones... |
| Mount the Lasers with 5min epoxy one at a time and hold them in place until epoxy gels. |
| Well, gotta 'fess up and tell you that actually I build 4 Vipers with 4 different motor configurations. Front view, all Vipers still in white Krylon base coat... |
| Viper 1 is a 24mm single, 2 is a 24/18mm over/under cluster, 3 is 18/24/18mm inline triple and 4 is the HyperViper with one 24mm and 3x18mm cluster... |
| Besides its light weight of 8oz, Viper 1 was very underpowered on a D12, cork screwing up just like the Estes original. #2 flew better on a D12-C6 combo, but still needed more oomph to straighten out. Viper #3 flew beautifully on C6-D12-C6, straight and true, and actually glided very nicely upright after the boost... |
| Viper #4 (top left) took off in a hurry on one D12 and three C6's, flew very nicely gliding like #3, thou quite a bit higher... #4 has enough built-in stability margin to fly chad-staged as well (top right) on D12-0 to D12-5. Was this perhaps the first ever documented Viper chad flight outside of Caprica ??? |
