Status: online 		I think it very fitting to duplicate the Tuskeegee Airmen Red Tail Project P-51C Mustang. I respect the accomplishments of the Tuskeegee Airmen and applaude the efforts being taken to put the full size Mustang back in the air. As a fitting start I went on the Red Tail web site yesterday (http://www.redtail.org/) and made a donation to get my certificate and commemorative rivet. Ordered a bunch of shirts too so I can be dressed appropriately when I fly this bird. This is a really cool airplane that is rich in history and exciting to follow as they work to restore it to flying condition.

Mine will be constructed from the Top Flite ARC Giant Scale P-51D Kit. I will be making a true scale fiberglass cowl for a larger 5.5 inch aluminum spinner. I will also be constructing a fiberglass razor back as part of the modification. This will be a great project.

Status: online 		Here is the start of the cowling form. I have positioned a 5.5 inch Tru-Turn Spinner ($185 by the way) in the proper position per 3 view drawings. The firewall had right thrust built in, so I have accomodated for that by setting a center line to the port side by about .150" at the firewall. This is a beautiful spinner. It will be a shame to paint it.

Thanks

Status: online 		Good for t_burley becoming a Red Tail supporter. It would be good to see this project raise awareness and benefit the rebuild.

Jeff,

Yes I understand that the D model has the wing extension at the root and that the B and C models do not. I gave this considerable thought and decided not to change it at all. It would create a major hack job of the wing that just isn't worth it. I am building this for the Fun Scale category at the NATS. Not everything needs to be perfect plus I would wager that 95% of modelers will never notice that subtle wing detail.

A more noticable feature that is easy to change is the wing dihederal being too flat on the TF kit. 3-views show a much more dramatic dihedral. I was able to get it up to around 8.25" at one tip by putting a 1/4" ply block on the top of the center wing spar and then cutting off the bottom to fit in the wing sockets. Pretty clean and strong. I now need to fill the wedge shape it created between the center two ribs. Not too big a problem.

It's not that the B didn't have a crank in the leading edge, it just wasn't quite as pronounced as the D. You have to go to the lightweight late marks to find a wing without the leading edge extension.

Status: offline 		As scalebirdman said, the B model had a similar wing to the D model, just not as pronounced. The only model P51 that had a straight leading edge was the H model. Jetco had a H model CL kit in the 60s. Wish I had not sold it although it flew like a rock.

Status: online 		I joined the center section of the wings. Since I increased the dihederal I filled the bottom gap with hard balsa and sanded it flat ahead of time with a large flat sanding block. After some filling and touch-up I glassed the center section joint today. The materials used are 6 oz. 2 inch wide fiberglass tape and Bob Smith Finish Cure Epoxy. I love to pull a lot of positive "Gs" so I added a band of 2" glass on the bottom of the spar all the way out to 4 inches beyond the gear on each side. It was then time for the "Toilet Paper Trick". You lay your glass first. Wet it with the epoxy resin and spread with a credit card. Then you roll a toilet paper roll against it to soak up the excess resin and push the glass against the balsa. You don't roll out the paper, just roll against the roll and then peal the outer layer off periodically and toss it. There is no better way to glass. Wait till you see this done on the whole wing. When your done there is little to no sanding required before paint.

Status: offline 		And here I thought that I was the only one still using the ol spare toilet paper trick. Excellent job! Glad to see more guts building Red Tails also. Can not wait to fly my "C" model this spring.

Status: online 		Good progress today. The cowling area is shaping up well. The chin scoop looks realistic compared to the photographs I am referencing. The top curve and spinner position look better than before. I drew the location for the exhaust stacks on the side. They will be longer and in a different position than the TF kit. They measure accurate per the 3-view. Kelvin at KELEO said that he will make a set of exhausts to fit this specific cowling modification. All I need to do is send him a fiberglass cowling set when I am done. He'll get the first one as far as I am concerned. That will be exciting if he can get them done by May 06. I'd like to use them in this bird.
