Viper Jet is alway been my favorite high speed performance sport jet. But it also can be fly slow enough for guys want to buy for first turbine jet.
Now with my new crow ailerons set up. I even enjoy it more. We can land her 300 feet runway every single time.
As for power. P-70 will fly it. But you won't have much fun as we have with P-120.
You won't go wrong with the Viper Jet. Many of us have log in hundreds of flights. Miguel did pretty good thread building the Viper Jet.
You will find plenty of support from Tamjets Demo Team and happy customer own the Viper Jet also will chime in with their support.
