F8U-1A Crusader 6mm foam
For years I've wanted to build a scale RC Crusader but very few kits have been available, only one that I recall actually looked like a Crusader and it had some issues as I recall. A Crusader was designed to be somewhat unstable to enhance its fighter capabilities and it did indeed. The downside to that effert made the Crusader a handfull to operate at low speeds and landing. All that aside the Crusader is an awesome looking and fast jet.
Recently, I have recreated the Crusader using 6MM foam and am ready to test fly the prototype (see attached). This model is approximetly 1/13 scale, 44" long and 28" WS, its all up weight is 24oz. with a 3S 2200mah Lipo. I have calculated the forward CG to be 5.25" aft of the leading edge at the Fuse., the jet has a large CG envelope and I want the first flight to be as stable as possible. I'm using a Super Park Jet, 7x5 prop and 25 amp SC. My power choice is the Grayson Mega Park Jet but I wanted to retain the least amount of weight for the test flight.
Initial concerns I have include the Stabilator that incorporates a CF tube and axel with brass bearings and an internally mounted servo. There is a little slop in the axel untill power is applied and then it appears to dissapear, strange. Any failure here will be bad so I will attempt to reenforce the axel with a pin prior to the test flight.
I welcome any suggestions or comments. The finish is not complete so excuse the lack of detail at this time, I will enhance that after the first flight.

Thank you! The maiden flight went well, good performance and speed but the Super Park Jet was very hot after the flight. I am going to replace it with the Super Mega Jet from Grayson Hobby for the next flight. I began decorating it so it now looks a little more like an F-8.

Indeed the F8U was a great looking and exciting jet. I built this one from scratch and after many exciting flights on it, she crashed due to my over confidance. I continued to try and get more and more speed
until it just became too much for me I guess.

Hi rharris&3,
You may have been already asked but, did you have a set of plans for your F-8? It is nice to see something different now and then I wouldnt mind knocking one out myself.
thanks for your time.

Hi Carlos,
I used plans for an A-7 Corsair II as a guide for the fuse, changing the nose and length. The wing was designed by scaling up from actual drawings I found in a book. The scale is 1/12, it is all 6mm foam and once laid out is pretty easy to build. If you diecide to build one and I can answer any questions, don't hesitate to ask.

Sure, I got them from Model Airplane News plan service, (plan X01951) $19.95. I belive the plan is 1/12 scale which works out good for the F-8. 888-235-2021 or airagestore.com
