You might try dialing down the rate on your rudder as well, something like 80% is plenty for the scale like flying you're into. Too much expo and it starts acting like a wet noodle, I don't go over 30%.

Also, is the control rod in the outermost hole? You can get more rudder with it in the outer hole on both the control arm and the servo control arm, that way, you can turn down the rate and not lose much control throw if you feel you need it. Personally, I use rudder for takeoffs and when in flight, to counteract adverse yaw. When landing, especially with narrow gear such as the Spitfire, I always keep the prop spinning to stop that pull to one side. As you know, you have to be on the ball when it comes to those last few feet of landing, adding too much expo will increase the amount of throw you have to apply before the rudder reacts.

Good points, and well-taken! I'll check out the position of the rudder servo arm. I believe it is not on the outermost hole but the second one in. I use 50 per cent Expo on lower and mid rates on the rudder and tailwheel, and high rates I reserve for taxiing with more rudder authority for tight turns on the ground. I've been adding some up elevator while on the initial takeoff roll and then ease out of it to neutral rudder as the aircraft accelerates. It pretty much flies itself off with very little up rudder command. Landings work out really well, although I got a minor prop tip strike when I landed just a bit too nose down attitude. But that was easy to sand the tips and repaint. Ready to go!

I've eliminated the background, but darned if I can figure out how to layer it on a new background!
Have a try!

Very Cool! You're halfway there! The guy who I wrote about to you who did the Robert Redford photo in his 1920s flying togs and then transposed him to our picture of a rc model of his Jenny The Great Waldo Pepper looked totally believable. Unfortunately, he passed away years ago but I bet someone out there has done this kind of transposing before and we'll be able to figure it out.

I finished the headset wiring on your pilot today so next time we get together I'll give him back to you. Looks a little more scale with those wires attached.
Question: do you ever put a drop of acrylic clear in the depression where the goggle lenses are on his helmet? I always do that for mine, makes it look a bit more realistic. I'd be happy to do that to your pilot if you'd like me to, or maybe you prefer to not do this step. Your choice,let me know if you want me to do it. They always come out really well.

I got a book, first of two from the Half Price store online on the 357th FG and their pilots. I always like researching things before I start in on a new project like the 1600mm P-51 if I do that.

Looks amazing Dave!
She flew as well as she looks I gather?

Hi Dan: I talked with the guys doing the 3D printing of the fuel drop tank. They said make the changes like reducing the wall thickness as much as possible to the STL that we sent them, when you're done send it to me and then I'll get it to them next week. I think we can reduce the weight enough, at least 1/2 of what V1 weighs to put it into the air sometime soon once we get it all together.

Cheers

I got 10 flights in on my Penrod and Sam yesterday. I was trying out some new Expo settings to try and reduce the tailwheel movement mainly on takeoff and landing rollout runs. Overall it went pretty well, although a few times I lost control of it near the end of the landing rollout and it went off the side of the runway sliightly. I was satisfied with most all the takeoffs that I did. Nothing damaged this time. Also did one drop tank release, worked great, as usual. Ended the morning with a flight of my FMS F-86F, one of my favorite jets. I hope to do some more tests maybe tomorrow morning, if the winds die down.

Flew Penrod and Sam again this morning, got three flights on it to further test Expo and rates. I fly in mid-rates with 50% Expo, which works fine in light winds. Low rates is backed off a little from mid figures, I prefer flying mid rates for now. When I'm on the ground, I switch to high rates, especially for any sharp turns I need to do while taxiing. I'm going to stay with these rates for the moment. Next week. I'll fly my other two P-47s, Ol' Cock, and Hairless Joe.

I also did a drop tank release, the 7th one to date on three different P-47s that I have. Flawless service, the E Flite release mechanism is great. Danger Dan and I are working on refining a 3D printed scratchbuilt scale rectangular 150 gallon drop tank and will have a company print it up. We did have a V1 version made as a basis to advance designs from. This one will be lighter weight and hopefully be ready to do test drops in the next several weeks. It would use the same drop mechanism that I am presently testing (E Flite) and should expect similar results, hopefully.

A pic from today's flying. I have 78 flights on Penrod and Sam now.

Great News, Dave. Penrod & Sam looks great. Finally nice enough weather that we could fly. Today winds are back up. UGH!
Best regards, Rex

Thanks, Rex. I have been fighting winds all spring! Sometimes I just say, "to hell with it, I'll at least go out to the field and See if I can possibly fly, despite the discouraging wind reports". More often than not on those occasions, I get skunked. But the best chances for me is to get up very early, which isn't hard this time of year when the sun starts coming out before 6 am and the dogs are barking to get fed and out for their morning walks. I left before 7 am this morning and it worked out great. Would NOT have worked out if I had waited, as the winds did rise to unacceptable levels.

So, I'm using my three P-47 models and working in Hairless Joe. I'm being especially careful with that one as I don't want to crash it, but I do put it through its paces. You probably find the same thing with your Lucky when you fly it. It gets more comfortable to fly the more you do it, like with many airplanes.

Dan and I are working on a 3D printed scale rectangular 150 gallon tank to add to the drop list for flying. We're not there yet but do have a prototype to improve to a flying droppable replica of this tank that they used a ton during the war. I don't think anyone else will have one, that I know of.

Have a good weekend.

Cheers

Dave
