RE: Another Skymaster Viper
It looks great Gonzalo!!
Keep an eye on the tabs attaching the thrust tube to the bypass when you get the turbine running. I found on mine that after a little heat, the thrust tube wasn't as tight a fit as it was. If the tabs aren't straight from the tube to the fixing point, they can straighten after use, so it might be worthwhile taking the 90 degree bend out of them before you fly.
