hi i am building a P38 from royal marutaka plans and i want it to go extreme fast, span is 74 inches. i have 2 choices for engines either Os46fa or Rcgf 10cc gassers. i already have the Os46fa so what you experienced guys suggest as i want it to fly as fast as possible. any comments are welcome.

Sorry it took me so long to post this. I acquired a Ziroli P-38 from Mike Fearing out of Ohio last August. Flew it quite a bit at our warbirds event here in Tulsa last September. It was fantastic. Flies on DLE55s with all hitch servos. Cortex gyro smooths it out perfectly. Landings make easy because of the brakes. Anyways, thought I would share some photos and video. Sorry for the quality of the video.

been awhile since I posted an update on my 150" Ziroli so here is some video of the maiden flight and a few shots of her with some paint on.

Looks fantastic! Haven't been over the RCScalebuilder to check on progress in a while, looks like I missed a lot. Well done!

Hi guys. It may be that these questions have been asked and answered before but I am spinning myself into the ground just thinking about the options. Working on a Ziroli P 38 with fiberglass booms. Gondola and wings are finished. Need to make up my mind on 2 issues.
1. Gas vs Electric. Gas would be a pair of DA 60s with one of them counter rotating. Electric would be ,I think, Hacker 80 and 12S setup.
2. To Fowler flap or not. Is the complexity of fowler flaps ala the Robert Almes design from MAN in the '90s worth it?
Thanks,
Sam

All I can say is that Electric if very heavy.
If your a builder as Im sure you are.. then fowler flaps for sure!

I have a 120" with counter rotating DA-50's which I would recommend. I also have a DA-60 and it's one heck of an engine with tons of power. But the 60 is a little more fickle and the 50 is great choice for that size. I flown the yellow on regular flaps and my current is on fowlers, hands down, do the fowlers. Standard flaps help with slowing it down but no where as effective at adding lift as the fowlers. Here is a vid of each.

SPSRC

Hi,

I am a new owner of a Yellow Aircraft P38. would anyone happen to have any type of instruction manual for this aircraft? Anything would be a great help.

Thanks
Scott

Nice looking bird. I am partial to the silver version. I have a FreeWing 1600mm electric that I love.

Hey fellas.... Got a new bird (Well, actually it is quite old). We had a member from Tulsa Glue Dobbers die last year. His name was Bill Roff. He was a P-38 junkie and very skilled builder. He had built a few scratch P-38s in the 90's. His widow had this one and we made sure to take care of her. So I bought it from her for a generous amount.

It was built in 1992. Originally had Supertiger 2000's on it. Airtronic old servos. Etc. It is beautiful and Roff built it up from plans (No clue as to what plans) and glassed the whole this. Paint is exceptional.

Anyways, we put DLE 35's on it and all new Hitec servos. Also has Robart make me some electric gear. It originally had gear doors, but I think Roff just simplified it and took them off in the 90's. Kind of a sport scale. With no flaps (Yeehaw!!!)

I have no idea how he built this thing. It is 108" and next to my Ziroli 114" P-38, the booms and fuse are quite smaller. But the wings seem longer than they should be. I think Roff added some length to the wings. Any ideas? Perhaps someone had seen this thing fly back in the 90's.

I have had it flying a couple of times. The old air breaks still work great. It screams pretty good. I will get video when I can. Here are a few photos.

Well fellas..... She's gone.... We got the entire thing on video. The servo lead to the elevator got caught by the gear on approach. You will see in the video that the elevator is gone. Somehow by a miracle I saved it from roadside disaster. Then flew over some house behind the club. Made it back and put it down.

Had a slight pitch up with no elevator. Stuck between a rock and a hard stone. If I cut power, it would stall and spin in. If I kept power on, it climbed. Had to bank back and forth and rudder the nose down to get it to come down. Craziest thing I have ever done. Here is the video.

Looks like you were not much different in situation than the DC-10 that lost hydraulics, used differential thrust to steer, climb and dive, finally crash landed in Sioux City, Iowa, with over 50% surviving. You mention death, but it looked like although there might be crash damage, a good possibility of repair and future flight. How is it?

It also reminded me of my days of flying single channel rudder only aircraft. There, I had no elevator, had to judge sink rate and watch the rudder use. More and it dropped nose and picked up speed. But I got to where I could land it dead stick within 10 feet of me without crashing.

Thanks Gostler.

it took some serious damage. To the booms at back end. Wings are good. Center section is repairable.

Motors and all equipment survived. Motors were actually unscathed.

I am not a builder. Wish I had the time. One of our club members is going to take it and work on it. Gonna be a while.

I am sure eventually it will fly again.

Sorry you lost it.

When everything is working on a 38, they’re pretty easy to fly, but any little thing wrong.....WATCH OUT!

Nice job trying to save it: most of my “final flights” on P-38’s end much more abruptly. You may have been aided by a good build (light wing load)

Thanks for the cojones to post the video. Any shared experience might be future help

Mark

How many flight did you get on it?

tuchadwick59

My Feedback: (31)

Thanks kram. This was the 10th flight. Started to really get her dialed in with the motor mixtures and throttle curves. I don’t use a sync, but rather a demon cortex gyro to help with the jostling when the motors are breaking in.

Really started flying well. The big Ziroli P-38 I have is perfect. Broke in motors, and the easiest thing I have to fly. You are right. We well built P-38 is very easy and docile.
