I had this one in a 1400mm Correx Spitfire, it weighted 2kgs, had plenty of power with a 3 blade 10 x 5 on 4s. I say Had, because the short nose on the Spitfire made it very difficult to balance. I had 100gs of led and a 3700 4s in it and it was still tail heavy... I've since removed the motor, ESC and battery and using it for Slope. Will need to install a weighted spinner for balance.
So in saying that, this is one BIG motor for a 1000mm W/s plane!

Thanks for the info Duke

I am expecting this one to come in at about 1200 - 1500 grams Duke ... she is a big mother ... I am even thinking that the wings should be full symmetrical AND it will have to have landing gear

Lockey if your W/s is going to be 1m to 1.2 m then I would be installing one of these -- http://www.hobbyking.com/hobbyking/s...trSearch=3010b

It has a twin brother L3010C which has a long shaft and pedestal mount... Very good motor and worth a look.

What about an asymmetrical flat bottom wing? the symmetrical wing I found difficult to make.
I can see some 2mm alloy flat bar being used in this one??

That does look like a nice motor Duke and I will be bearing it in mind

Aluminium would probably be a good idea for the undercarriage eh Duke

You talking something like this ?? (see pic) .. probably a good idea mate, more lift too, I was going to go with a KFm wing but I think this one deserves something a bit nicer

Oh yeah baby! that's the one! Do you think the bottom wing would be thinner than the top wing? ( height not cord)
I was thinking the undercarriage would be set into the bottom wing, running through the fuselage and under the battery tray? That may create a very strong structure for the bottom wing and the wheels.
You could slot the alloy and locate the bottom spar into the alloy wheel struts as it runs down the angle on the bottom wing, then out to the wing tip struts...... Wow ideas flooding in ... Lol...

Duke, whats your thinking behind a thinner wing on the bottom ??

I think we are both on the same wavelength about the uc running through the fuz and in the bottom of the wing

Maybe the wings could be kept quite thin to give it a racy kind of look ... maybe 25 - 30 mm and constant right through, even when the chord gets bigger ... that will make then easier to make

First nice design so far.

Second point of order. You're doing a Reverse-Stagger Biplane. Any bipe with the top wing leading edge that is not directly in line with the lower wing, has, by definition, a staggered wing.

The Beech -17 series got its nick name from a shortening of the actual name. It has a reverse stagger wing. over time, the reverse disappeared from the name but that is where it came from

Keep up the great work

Lockey, have you dropped development of your "modern stagger wing cabin bipe" design?
It's more in line with what I'm capable to build & fly, and was looking forward to giving it a try.

In actual fact Major ... It's a "negative stagger wing bipe" but I think we will just go with stagger wing
