Thanks for the good wishes and the video Jon. Iappeciate it. I think I"ve seen your vid before on YouTube. Thanks for not goofing it up with a bunch of music. The sound of that great running 4 stroke is music enough for me.
My first Intruder is still out in the "hangar" less engine, servos, etc. I bashed the vertical off of it with a ceiling fan and decided to start with a new airframe rather than rebuild. It really needs a complete overhaul. Although it's structurally sound, it needs a cosmetic make-over. I flew the old one with an OS.61 two stroke and it was a great flyer. That's why Ichose it again ...and the price isn't bad either. Airborne Models even shipped it for free as a promotional deal.
The Saito .91 Ihave mounted on it should provide great power. Ijust need to find the right prop. There are a few folks in our club who have owned and flown the Intruder and they didn't like the way it flew with a 4 stroke. Ifigured they didn't have it propped right so, I'll be doing the prop testing thing until Ifind the right one. Ilike wood props and have a 13x8 on it now. It seems to pull fine on the ground but, the tale will be told in the air. It's difficult to decide which prop is best by using the experience of others due to the variety of engines used but, I'll get it figured out soon Ihope. It's too close to the ground to take anything longer than a 13" prop unless Iinstall bigger wheels. I'm not sure I like the stock tires anyway so Imay go with a set of 2.5" wheels and experiement with 14" props.
Take care and enjoy your Intruder. I agree, it's a great flying bird.
