Here is the [link=http://shop.traplet.com/product.aspx?c=584]web site[/link] for the plan . The plan makes a 2 seat trainer that was powered by a 5 cyl Kinner radial. The crop duster variant 9 ( ther was one that flew in the '50's ) used a 7 cyl Continental. There is not much on the web- believe me I've looked to make the crop duster. But here is what I've found

I have some more somewhere but see what you can dig up on the other side of the pond.

Thanks! This looks like a great candidate but weighs 15#

And the diameter of the cowl is not mentoned either but I'm sure the nice people at Traplet would probably know.

Mick Reeves makes some great plans/kits. I really like the Bleriot at the bottom of this page. I have seen videos of it flying.

I might be ordering the 777 instead of the 7-35. After coming across this plane and watching the videos I am pretty much sold.

http://www.aero-works.net/store/detail.aspx?ID=232

He used a saito 325 radial and the specs are similar to the 777. The weight is within 7 ounces. The evolution oil I have from horizon will work with methanol so I guess it will work for break in? Horizon doesn't list a 22x12 prop. Is a wood prop ok on this engine? Thanks!

I flew my UMS Evolution 777 radial engine powered Black Horse Corsair at our annual club War Bird event today. The engine and plane performed very well and were quite impressive. I had the only radial powered planes at the event and they got quite a bit of attention.

Did my flush and maintenance on the UMS Evolution 777 radial engine today. The Corsair and other planes will have to wait for a few weeks while I have my eye surgeries. I will probably be out of the game for the next several weeks.

Best wishes to all,

Roger the Radial Rabbit.

Hey 77chickenhawk, I enjoyed chatting with you at the war bird event. You sure had a very nice giant scale zero. Too bad you don't have that ASP 400 radial to put in it like I will put in mine. Ooops! shouldn't talk about that here - wrong forum! Best wishes but don't hold your breath about that loan - ha ha ha

LOL. I don't know if I want to put ASP 400 in it. I think I'll just fly at the way it is and when authentic scale comes out with her 14 cylinder Radial in 16 scale I'll get that bad boy and put it in there

Hi Guys,I am still looking for a reason to buy another radial(aren't we all), and I hope I might have found it.Just purchased a Great Planes Waco from Tower Hobbies,and I was once again thinking about the EVO 35cc radial,as it will fit in the cowl.The plane should weigh in at about 14. 5 pounds.Whileit certainly would not be overpowered,does anyone have any ideas on whether it would have enough power to fly in a scale like manner?

I was thinking of doing the same. I know it has been flown with an OS FT 160 (twin cylinder 4 stroke) which should be similar in power. It is also flying the Great Planes PT-17 military Stearman which is an even better candidate.

It's power loading will be about 113 watts per lb. that is somewhere between scale and sport flying. It should be just fine.

Hi Guys,

I am getting ready to build a ScaleWings F7F TigerCat. I had chosed to run DA-60's for power but was worried about vibration on a composite airframe. I have read most of this thread and everyone that has these motors seems to be happy with them. I planned on the UMS-77 for power. I am wondering how much forward speed I will loose with radial versus a 2 stroke engine. I would like to run a 22x10 three blade if possible. Has anyone had any deadsticks with these line of engines?

Thanks,
Doug

The engines are reliable but tuning knowhow is required. A mistake is to make the idle too lean which will make the midrange too lean and cut out. -Tom
