I fly with Joe and he is still running the 60's on his models. He has also been cutting down his ailerons and to about 12" I am sure the 47's would be up to the task for the cut down surfaces. Or on the stock surfaces to 180 at least. But the big problem with the 47's is that the drive train is not as durable for those less than perfect landings.

Surely, P-Y-F?

Can't believe you'd be coming all the way to Rushup for a NNE 10 mph & ultra-shallow backside?
But I hope so - see you there

Guys, I wanted to have flight reports by now with my D47's but I've been swamped with work getting ready for a test event. Plan was to fly it during last weekends outtings but it just didn't make it. I won't be able to get back to it until November so I'll have to leave the D47 reports up to one of the others. I have't read back to see if any of the other posters have D47's so FAIK we could have already had a report

At least I haven't crashed it yet

Jim

I was lurking and saw the D-60 vs. D 47 discussion so I thought I would chime in... I can't tell you where the limit with a D 47 will be but Bill Lorenz went 180 mph with them in his plane and there didn't seem to be any issues...

Food for thought.

I have gone 200+ with them a couple times with long arms (not good) and 4.8V. Im sure they will be good to 250 with the right geometry.

A hugely enjoyable day.
Might not have been enough drive to put anything 'on step', but it was Rushup the "wrong way round" after all, & loads of fun. Great to meet you guys (Adam, Rick/"Zim" & George) after much indirect & some direct internet correspondence.

To Adam & George, who left a bit earlier, you missed the serenity of the early evening - not much wind but a backside like whipped cream.
(Hmm , reminds me of a few girls........)

Sorry to hijack your thread Joe, but there were 3 D40s up there, two of which stretched their legs frontside, & coped admirably in less than ideal conditions backside.
Beautiful little planes, in the flesh even smaller than I imagined, yet very strongly constructed, & with a surprising presence in the air. They seem to be more visible aloft than my 54" destiny; can't quite figure out why.

Yup, but can't recall the speeds - probably because they weren't relevant to what was just a great day's fun
But I think George may have got a PB. Perhaps Adam or Rick will clarify: I'm damaged by a session in a 500 year old pub on the way home.......

We may not have 5000' high mega-sites, but we do have ancient hostelries with tasty barmaids to add to our lower altitude pleasures....

BTW, I resent being described on site as "the guy with grey hair"; these highlights cost me a fortune.........

No worries here. You cant imagine how good it feels to read about your fun flying trips with the D40. Keep them coming.
I have had a few others say the same thing, "that plane doesnt look small once it's in the air". I dont understand it either but it sure is a plus. Have fun flying.

Almost

My fuse is done with the elevator, and the wings are servo'd, so its servo cover, reciever, battery, and balance. Then wait for wind. How is the weather Joe?

D40 ROCKS!
Wow what a day we had up at Rushup yesterday!
I finaly got to fly the D40 on the back side and do a few laps with it.
It was my first ds laps with a moulded plane too.
To say I was a tad nervous was an understatement... but took some deep breaths and fired it into the southern backside of the hill.

It took me a few go's to get it into the groove and I must thank DSMan Graham for his superb coaching and giving me some very good 'Secret Stuff'. Once I got my head around that I went 93mph!

She is a little monsta on the back side. Lots of fun and a couple of moments that I managed to get away with, with some 'lucky' stick twiddling.

Some time after the 93 I was shaking a bit too much so gave the trannie to Adam and he flew her a bit omn the front while I got myself together again.
I then did a few more laps on the back but I dont remember the speeds and they were no higher than I had gone.
After one particulaly rouge moment, which I manmaged to get away with again, I said 'Thats it I've had enough! '

I landed the little ship on the frontside and took her home in one piece.

OH YEA! The D 40 is a very special machine... Bigger in the air than in the hand, but man you dont need to take your eyes off her (for a quick glance at the back side as you dive in for example...) wont be doing that again

I did find I needed some down elevator to stop her ballooning as she came up the hill so I am going to have a model memory for front side flying and one for DS. More work is needed on these settings for sure.
Then, I'll go faster!

I managed to do 101mph with my JW too, but the best flight of the day was with the D40 and the icing on the hill for me was going home, D40 intact and the fastest time of the day for a D40!
Ha Ha!

Thanks Joe. Well Wicked mate.
Cheers
George
