That came out real nice Tony!!! You did a great job on the camo. You have to get a video of this thing doing a slow low pass. Just remember ..... don't point the guns at anyone even if they are not loaded.

Sweeeet.

Tony, Nitroplanes had better stock a boatload of these planes, once people have a look at the finish job you've done on yours. (And it would be nice if they got in some parts, too).

Thanks Guys!

Blade-I hope Nitroplanes stocks a bunch more because have a lot of DC-3 ideas I'd like to see in the air.

Yesterday, I noticed the wings are drooping just a little, so I'm thinking about adding a carbon fiber rod to the bottom of the outboard wing panels. The additional dihedral would help stability. Anyone else seeing this issue?

By the way, the modified GWS props give ample ground clearance.

Best,
Tony

R4d-5

For those of you that fly in the snow, how about a R4D-5 mod? I'd like to see one of these Dynam birds flying off of snow.

Best,
Tony

all of the planes on this thread really look great! awesome work, guys. i just ordered the 7x35 three bladed props for mine. these should look great (not as nice as tony's, however) and solve any prop clearance issues. nice weather forcast for tomorrow (no wind) so i am looking forward to getting my dc3 up (only for the second time so far). i just ordered my next plane, the great planes pby. looking forward to that one, another ww2 favorite.

These measurments were done with a higher grade 25C 2200 3 cell vs the stock battery. I figured if we did the measurments with a high quality pack, then there would be no issues with the 15c stock pack. The 40 amp controllers and motors will handle either with no issues. You might want to watch the stock pack with the 8x4's. The 7x3.5 will fly the C-47 with plenty of power to spare. The 8x4 will hover the airframe. Way Way too much power. I also reversed the right hand motor and put a reversed prop just for the cool factor. It really is sweet to have counter rotating props. I will be flying the 7x3.5's.
Scott- Have you flown the GWS 7x3.5 3-bladed props yet? The main reason why I ended up cutting down the GWS 8x4 3-bladed props was that the 7x3.5 props were too flimzy/flexible and I was concerned about lossing thrust. I watched a video by Dave Powers concerning GWS prop performance at speed and really used his cutdown example for the basis of mine. In the end, the cutdown 8x4 props looked a little more scale and provided better rigidity. I'm not sure about performance of these modified props until I run the motors.

I look forward to your results!

Best,
Tony

tony, you found those 8x4x3 to be flimsy? un oh....i have a bunch of them commnig for my next plane....mainly for looks, because that one is going to hang in my hobby room (assuming i can keep it in one piece). if they are i also have some stock 8x4's comming too.

my 7x35's should be here in a couple of days, if scott does not beat me to it i'll post a flight report as well.

rob

ps.....any pics of the completed plane?

rob- No...it's the 7x3.5 that are too flimsy IMHO. The 8x4 props are better and would do fine stock. By cutting them down to 7x4 they seem to have less flex and of course better ground clearance.

I rarely build during the week, so...no progress on the AC-47. The life of a full-time single father on active duty. I wouldn't trade it!

Regards,
Tony

As of 5 minutes ago, Nitroplanes is still saying 4 to 6 weeks before the Skybus is back in stock.

Sometimes they get back in stock sooner. The last time they were sold out Nitroplanes said it will take about 4-6 weeks for it to get back in stock and it ended up only taking about 2 weeks. Who knows it may be sooner

I just got off the phone with a real nice sale rep who will be following up with more specific info when she gets it. I'll pass it on as soon as I hear back!

Tony, I flew the DC-3 Sunday and I really like it, however I was not impressed with the 7x3.5 3 blades. It flew it fine for all general purposes, but I was not satisifed with the thrust at all. I think you are correct in saying that the blades are flimsy and loose alot of thrust. I could hardly tell any difference from 1/2 power to full power. You could hear the motors rev up real nice, but there was hardly any difference in thrust. It felt like a car's clutch that was constantly slipping. So, I will be flying it this weekend with the 8x4's. I am sure they will make a big difference because when I checked them on my watt meter and held the plane vertical, it wanted to climb straight up right out of my hands. At full power the 8x4's are right at 24 amps. The controllers should be fine rated at 40 amps each. I wonder what the 1100kv motors are rated at?
