SPA in SE Texas is alive and well. I intend to try competing in a couple upcoming 2023 events along with AMA Masters events. My goal was to keep it light and simple by not using retracts or a tuned exhaust. Like the previous SF IV I built and flew in the early 2000s it's powered by an ASP 61 an OS clone outfitted with an OS 7M carb. As I do with 2c and 4c engines I'll be using CoolPower 30% heli blend for fuel. As soon as the weather permits I'll test run the motor at the house before going to the field.
Mods and options.
- Added a rudder sub fin
- Removable canopy
- dedicated servo for nose wheel steering
- standard muffler replaced with a Macs flow thru
- Wing build using an Adjusto-jig
- Sheeting added top and bottom of stab/elevators
- Rear bearing supported pushrod to manage split elevator halves
- 2-aileron servos
- Pull-pull rudder system
My previous Sun Fli was a lot of fun to take out Sunday evenings and weekday evenings during calm winds. I am hopeful this is too but add an element of being competitive in SPA Expert. Whether or not it's competitive soon I'll start construction of a Bridi Dirty Birdy I plan to use retracts and a tuned exhaust.
