The changes they made

Starting with the new ecu......

- GSU connects via a servo cable, no longer the large dateline cable used on all the dinosaur systems.
- Smaller, lighter, much more processing power.
- Due to more processing power, lower idle RPM, faster accel/decel is capable due to higher RPM accuracy.
- Single cable from ECU to engine (seperate valve and pump cables).
- More adjustable parameters including preset accel/decel curves all custom to every engine built for maximum performance.

Now the engine........

- Starting with a brand new Billet CNC compressor adding more power and efficiency. Thrust=3.8kg! With a weight penalty of <5grams.
- Single cable braided into a special connector used for the new ECU.
- Redesigned combustion chamber, exhaust/thrust nozzle, center cone, stronger welds.
- Micro JST added to starter motor wires from factory to aid in removing and installing fod screen.

The Twins have arrived now just to see what they will fly in the up coming months. I am impressed before I even got them out of the box

After the main install of the turbine and exhaust pipe. The built was straight forward. I upgraded the AIL and EleV servos with the flaps and rudder servos will be upgraded too in the near future. Installed all the fuel system, electrical, and radio systems.

Getting there, designed motor mounts that could use the built in edf mounts.

My newest completed build. Has been test flown and it performed great. Will post pics next time I go fly it. I was torn between building one small jet with either a wren 44 or a k45, or building a big jet like 80n+. I decided to build small p20 and medium size k60. Here is the small project. Pictures show project from start to finish. Took about 2 weeks of custom building on the airframe of the stinger 90. Most time went into building engine mount and cutting of foam and wood parts to allow install of components without jeapordizing the structural strength. My goal was to have smoke on board this jet orginally. But decided the system was to heavy for the performance I was looking to attain. Ill be saving the smoke for the new HSD Superviper when I get around to buying it All the bells and whistles! Installed telementry, backup flight battery, tamjets UAT and antistatic tubing, and went abit over board with the receiver but as insurance, the P20SX isnt cheap!...Continue Reading
