Status: offline 		I built, flew and enjoyed a D-18, and as far as I know, it's still flying in New Jersy. The G-38s will be perfect, I ran US 41s, but I'm flying a C-47 now which is much larger, and they pull great. I flew the D-18 on one engine many times, no big surprises. one thing I would recomend, put extra and larger aileron servos in , the vibration at the end of the wings will break smaller ones. as for the starters, the 18 can carry the weight, but it might mean more nose weight, which is already quite a bit

Do you remember the nose weight you had on your d-18 ?.
On the drawings ,it seems to me that the fema starters comes a little bit in front of the CG,but i am not sure

Thanks!!

Status: offline 		I had a Fema starter on my !/3 Super Cub/ G-62.It was a great combination.The Fema starters are expensive but are high quality.The starter electric motor can be positioned anywhere behind the firewall.I also had a choke servo which is necessary for stand off starts and dead stick restarts.I can still remember shutting down at altitude,gliding around for about 10 minutes,making an approach on final , and then you'd hear and see the engine cranking while I dialed in the choke till she fired just before she would come over the numbers...It was awesome..SteveD

Status: offline 		Ketil: In my long experience with gasoline engines of various makes, I would use the Fema starters ONLY if you want the scale effect. For safety, such as having one quit, I would not bother. These engines, if properly cooled and set are going to run for the whole flight.

Just something to consider, as these starters are not cheap. Tex.

It is fore the scale appearance.
I knew that the d-18 had to have weight in front,so i wanted to have the nicads to the starters and rest of plane in the nose of the d-18.

I am found of 3w and moki , but this is not a plane i am going to make hole in the air with,so fore the same price fore the 3w 40 i can by a zenoah 38 with a fema starter. thats what i thought.

thanks

Status: offline 		I think it took close to 8 pounds in the nose, but I had an interior, and a working door. But the 18 is really a stubby plane, and it takes a lot of weight. I wouldn't worry about re starting a G-38, if it quit, it's probably out of gas!! besides, while you are concentrating on a restart,you might lose the plane.

Status: offline 		Ketil,
I ran a pair of G-38's on my Ziroli B-25J and found them to be ultra reliable. Never had one quit. I agree with Brad, if you loose an engine in flight you sure don't have time to fool around with trying a restart. It's one thing to kill the engine on a Cub and restart it in the air (very impressive) but quiet another to do it on a twin.

Unless you are going for ooohs and aaahs on the ground (which is a totally valid reason) with the electric starters, I can't see a reason to run them. Seems like a lot of extra weight and expense.

Good luck,
Ken

Status: offline 		I agree with them other guys Ketil,it took me a while to get my Cub restart routine right.It can be a handful while flying a cub so a twin would be tough to do.The G38's are a reliable engine and dont they come with spring starters if you want them?

Status: offline 		Thanks !!!!!

you have right ,i will not have time fore a restart,i probably want the the plane down quickly as .. if a engine stops.
so i knew myself,i will be fully concentrated on bringing it down in one Peace,no time fore other things.
I have never taken a twin to the air,but i have been up with large models like a spit 340 cm, is the twin a lot harder to fly ,should i start with small twin at first? or doesn't it matter?

Status: offline 		Bigger flies better Ketil,I'm no twin expert yet however.I have a Ziroli DC3 in a box that Im getting anxious to start.I'll probably be using the G-38's for powerThey say this bird is one of the best to get started on twins.
I think if you have everthing setup correctly with a pair of reliable engines you'll be ok...Steve

Status: offline 		Ketil,
With both engines running correctly, a twin is no harder to fly than a single. A large, correctly set up, twin will be as easy to fly as a small twin. Be sure to get some experienced help when you fly it the first time.

Status: offline 		The D-18 is a very forgiving twin,the one good thing about it is the twin rudders, they line up right behind the props, so when you power up for take off, they quickly become effective. also, if one quits, you still have prop wash over one rudder. I have flown multis for over 20 years, a Ziroli C-47 and a Don Smith B-17 currently, and I would advise a big twin only if you have someone with experience with twins to help. make sure you know how to fly with rudder ( a lot of people can't) there is no fudging it when one quits. Notice I did not say IF one quits, it's WHEN one quits. And remember the three rules of Warbirds: #1- keep the speed up, #2- don't let it get too slow, and #3- keep the speed up .
