p-39 was my first warbird although mine was a jemco fun scale, covered with silk spun coverite and a McCoy .35 for power. all of which most of you know not of.
both (p-39 and p-51) are good stable platforms with good ground handling, though the p-39 gets a + for being a trike.

The reason I asked about the flaps, is the P 38 has a long rudder that extends close to the ground. It means to me that angles matter. If I pull it up too quickly, it will drag the tarmac. If I land with too much angle from the flaps, again, they might scrape again. I need for some of the P 38 flyers to weigh in on it as I am going to really try to keep this plane clean. Too much flap, the plane noses up so I need to play with it while flying. The B-25 in the simulator has the same problem but I land it without flaps. I take it off fairly level though and I don't think I have scraped the bottom with hot landings. Just trying to learn the ups and downs, thanks! Russ

Originally posted by ICM View PostNo, I'm referring to the E-flite P-39 Airacobra. OP said he was considering a P-39 or P-51 as his first warbird. The P-39 has flaps and I use them depending on wind. Little to no wind, full flaps; moderate wind 1/2 flaps; 10 mph +, no flaps; 15+ mph, I reconsider flying

F4 Wildcat is a shoulder wing design.....very easy to fly. Grumman F7F....while hardly a trainer, it almost flies like one. Another shoulder wing

Hey Joe, I was a paper and dope plane guy back in the day. We were no a rich family back then so wood was what we did. Which is why only one plane is left after I wrecked mine on a windy day. I think it was Cox 049 engines we used. Most times we couldn't fly because the engines would not start. Boy was it fun back then....said no one who did the walk of shame after a crash.

like everything else in life you pay your money and hope it works out! good luck.

p.s. we used to use a propane torch heat the head up with it a squirt of fuel in the exhaust port and spin the prop and away she goes every time. then the went to aluminum heads (glow plugs) and they did not survive the torch.Platt: fw190d9 Dynaflite:PT-19 IMP:Macchi202 ESM:fw190 ESM:Tank, Hien Jackson:DH-2 BH:macchi200 Extr:fw190 Holman:me109F H9spit2 FL:F4u,spit 9 FW:me262 GP:us60, Stuka, cub, F4u PZ:me109, albi EF Hurri, T-28 FMS: 2x fw190, me109 Lone Star:Skat Kat RSCombat:2xfw190d9

some planes rotate nose down with the addition of flap (fw190, me109, spit, hurri,p-51, p-47) they need very little trimming between clean and dirty. then there are those that don't rotate when dirty (t-28), the t-28 requires 16 clicks of down E with 45 degrees of flap to continue flying level. I have no idea which group the p-38 falls into but one thing is for sure it has to rotate towards the nose to keep the lift vs mass equation balanced so tail boom strikes on landing should be a low percentage. again not knowing the p-38 very well I see it had tail boom strike skags under the rudder, I would assume those come into play when taking off fully loaded (extra gas, bombs, or bullets).

Would a P 38 constitute a shoulder wing design as well? Just looking at the model, I would describe it as the same and add the wingtips are angled up as high as the cockpit.

Like a Cub....everyone seems to think they are like a trainer....they are NOT. Scale Cubs take a bit to fly well. More to it than just the wing. Stay as simple as possible

An awesome Skymaster is flown by Redbull at airshows....Google the Redbull Cessna.....some pretty fancy flying too

Ok I have a couple questions to ask first is regarding FAA license can somebody tell me when this will happen and what will it require? Second is the TMA p51 looks like it has good landing gear that absorbs shock of impact does the eflite p39 and the eflite p51 offer the same shock absorption

Well, over the weekend I found some time to start tuning the P 38. I limited it to taxi since I have to be able to get it lined up. It was windy in the Carolina's and too wet at a soccer field I use. Parking lots can be found. Its straight and the tail is true as well. The rest will have to be in the air. I did that upgrade to the landing gear so my purpose was to see if there was any of the gear askew. All went well. The new gear have springs in them so this will be good since we normally have wind to deal with and I knew hard gear would not suffice for that without risk. Sometimes I come down on just two wheels since take off direction varies. Did you ever use the simulator from RF/HH? Be curious to how accurate it is to the real thing. I know it helps develop control skills but wasn't sure about how good it is for practice.
Nope. Only used some free download on my iPad. Not a great sim but it does develop the proper memory of controlling the plane headon and going away. That really is the biggest hurdle to prevent a dumb thumbs crash. Making the sim fly close to the foam plane is a great bonus.

Good point, when I actually received my P 38, it had hard gear on it as well. After watching several videos of flyers doing the taxi runs it looked odd how much wiggle the plane was doing. So I went to Motion here an found they had an upgrade kit with springs. This is the pic for the P 38 what I put on it. Its got springs. and moves which is good. If the tires are too hard, those can be upgraded too.

Did the same upgrade on the F7F-3 Tigercat from FlightLine. Lands really nice with them. Here is a link to a flight video.

Nice flying between the windmills. LOL, but I have to take off and land around soccer goals. Flight hazards I guess. Nice flying!

I'd say it was a good investment. I will have to fly from a grass strip here where I live and at the flying club. But, I have two hard runways about 85 miles from here where my brothers fly. When I taxied with the hard gear, it just bounced like crazy as the grass at the grass field was rough. My maiden flight will be in two weeks I hope.
