Direct Connection F-20 ARC
Do you think that the ARC version of the F-20 would be able to reach speeds of 100+ mph? What engine would be a good match for this plane. I would like to get ready for some DF fun.
Any thoughts are aprreciated.

Ive got one, and want another for a spare, this is an awesome flying plane, Mine has retracts and a YS.45. I have been told that someone radared one with the same engine as I have and it did 125mph. So it is easily over 100MPH, it flies pretty quick! I fly mine off grass even.
Look in the picture post and you will see another view of mine and another one there..

DC F-20
Hey John, do you think that DC F-20 with a hot Jett 50 and pipe could reach 150?
Looks like a sleek plane that could come close.
Doesn't Cermark make a .60 size?

difference...
I believe the DC F-20 has 47" wingspan...Cermark has 56".
144mph...that's good...really good. With a different pipe could you get more or do you think that's the limit, and at what rpm was that at?

DC F-20
Okay, I just ordered the plane, should have it by friday. JohnVH what type of retracts did you but on it?
I am still toying with the engine..
YS .45 Sounds good, what about an OS .61FX?
Should be building my DF by next winter.

I ran a 9x8 prop and it turns 17,000 plus rpm on the ground.
15% nitro fuel. It has retracts of course.
I haven't tried anything else, it just runs great, even idles nice.

Oh man, I feel like I'm following you around John! Heh Heh, can't belive it took me this long to make it over to this thread. I'll refrain from posting a picture of mine. If you want to see it, follow the link below to my website.
I have a Rossi .45 on mine with a 9x8 prop. Don't have retracts on it. I have another one that's in the kit form that I did buy some Spring Air retracts for. I bought the 302 kit. Even without retracts, it flies between 90 and 100.
I'll agree with what John said. It's a very fun airplane! One of my favorites.

What kind of retracts are ya using?
Thanks,
Gary

Hi Pilots-
how fast do you think one of those would go if I put a specially prepped OS.91dfx (26,000 rpm) engine on it and a Dynamax fan rotor-thats right-just the fan rotor WITHOUT the shroud-just like you mount the prop?It should go PDQ.

F-20 w/DF
The rotor alone would probably be useless without the shroud, but it might work.....you'd probably be better off just using a prop and propping it to turn the 26,000 RPM. Just my .02,

Jack,
I would think there would have to be some MAJOR modifications done to accommodate an OS df motor. IF it could be done, you would have a "missile" on your hands! My guess....200+ mph.
Have you considered a "Regal Eagle"? I personally am not familiar with this, but I've heard good things about it, especially for the price.

AirGar,
been flying DF's since 1979-have scratched alot of homemade stuff and I have run a fan rotor as prop-it DOES work!I have built and flown 2 R.E.'-but they are too slow-but they fly good.
