Dynam
WACO. 1270mm 1800g 40.3dm2 WL 45gms/dm2. Detrum 3720A 650kvmotor 50amp Aerostar esc. Max power on Detrum motor spec 42A 630w. CG 75mm back from top LE. With 2200mah 60c 4s 1780g. cg 75mm ok . Power req 500w/600w. 12x10tgs FF 640w 42 amp16.6v ok.
this is my Mk1 version, dont know what the mk 2 power is but a bit more is always welcome. You will need some patience assembling and setting up as glue was sparse on mine and I had to straighten a few panels with weights and re glue the cf rods in the wings. I also replaced the hinges with hinge pinned nylon and added extra magnets to the hatch after adjusting the magnet fit. I have had this plane for a couple of years and its a great lazy day flyer in the setting sun. I also used a couple of cf sticks to grip the hatch.

So Dynam recently released a V2 of the Waco with a new 3720 800kV motor and 50A ESC. Much better punch now!

Here is my video review of the V2 for those that are interested!

Great shot, Hoomi!

I had the P&S camera on the tripod recording video while I flew yesterday. I pulled this frame from the video of my Air Hooterville flight. I have shots of the plane in flight, but having one with both me and the plane in the same frame is a keeper. She was on final for landing in this shot.

Thanks, Boomer.

Hoomi, there isn't a clear coat on it yet. It is just Rust-oleum Painter's Touch Ultra Cover Gloss Marigold. When I do clear coat it, I will use Minwax Polycrylic Gloss. I'm using that on my Tigercat and it looks really good.

[Hoomi]

What did you use for the glossy clearcoat, Prowler?

[boomer108]

Looks brand new Prowler, nice work! That's my favorite biplane to fly.

[Prowler901]

Thanks , TJ! yeah She's a beautiful flyer.

[Twowingtj]

She looks great Prowler! One of the better scale foam bipes out there. Always enjoy flying it.

Last summer I dumb-thumbed my Waco into the deck. So after a year of looking at the pile-o-parts, I finally got her back together. And, I gave her the paint job I've been wanting to. Re-maiden will be next weekend. I'm still waiting for the new prop adapter which will be here on Monday. Overall I'm very happy with how she turned out, and I can't wait to get her back in the air.

Excellent graphics by Callie as usual.

I bought my Waco from a friend. Another friend has had one for quite awhile and I've always admired how it flies. His has the signature dihedral in the upper wing outer panels so noticeable on full scale Wacos whereas mine doesn't. He claims he did nothing special during assembly to achieve this. I've also noticed that almost all the Wacos in this thread have flat upper wings like mine. From the front mine looks more like a Stearman than a Waco. Mine flies great but the lack of dihedral bothers me to the point that I've ordered a replacement upper wing set. The new upper wing WILL be built with the correct dihedral. Before and after photos to follow.

I have to wonder about Dynam's quality control. I ordered a replacement landing gear set, and the strut covers on the replacement were on backwards.

Fortunately, they were easy enough to remove and switch around.

I swapped the outer wheel pants as well, since I have my custom decals on them, and while I was at it, I moved the old wheels to the new gear, since the new wheels seemed a bit wider at the hub, and were not spinning freely inside the pants.

I managed to get my cosmetically modified one maidened last week too. I added 20g of weight behind the cowl and ran a 3000mah all the way forward and I must admit I wasn't expecting the take off charachteristics this plane has. Once I got it trimmed up it was a joy to fly-tons of lift, but I did notice it does not like slow flight and will drop a wing on you very easily especially in the turns, but once I got used to it the plane was a blast to fly. Was good to see I still had Snoopy, Charlie Brown, and Woodstock still onboard after the maiden flight. I had thought about selling this plane despite the money it owes me (the custom decals cost more than the plane), but I actually enjoy flying it. It will remain in my hangar as my only Biplane I think.

I fly mine exactly the same way 20 ounces in the nose and a 3000 4s battery and it flies great and your right it doesn't fly slow but it is quite acrobatic at speed and fun to fly. It's my favorite bywing.

I finally got the maiden on my Waco today oddly enough it flew a little nose heavy. I was using an Admiral 3000 4s with 2 oz of lead behind the cowl with this it set the slightest bit nose down at 70mm on cg. When I got trimmed for level flight at 50 to 75% throttle I had about 2mm up trim on the elevator. The Waco flew good but did not behave very well with a 10 mph crosswind at 90 degrees on landing that big vertical stab catches a lot of wind. I’m really pleased with it overall I think I will really like it after I remove the nose weight and fly again.

Yepper FF.........flying that with a 3000 and 2oz lead in the nose is equiv to flying it with no lead and a 4000 4S.
I fly mine with 4000 all the time with it as far aft as possible(no foam hacking) and it requires the approx. 2mm up trim.
Remove that lead and you should be good to go;)

I have a MAS beech prop to go on it before I take it for a maiden flight next week. I always balance the props on everything (I even check my pre-balanced MAS ones). No guarantees but you might see it on my friends YouTube channel if I take it down to Tokoroa in 3 weeks time when we can fly there again-the airfield is booked for the next two weekends and I know Bruce is keen to see my “snoopy” plane lol

[CaptAmerica]

Yeah my stock prop was well out of balance. Nothing alittle sandpaper couldnt fix.
