Today it was warmer, 39F, with no wind so I took the Camel out for a flight. Guess it was too cold for the Fokkers cause I did not see any.

I'm putting skis on my SE5a, then just need a day without 30mph winds to try them... Haven't seen a Folker around here for some time...Froze up I'm thinking ?....Don

Hey Murph--- When did ww1 bipes learn to do the "headache"? (Not sure if I can spell "lomcevec"!!) Lee W. Palm Beach

HAHHAHAA. they learned that as soon as I maxed out the throws and took the sticks....:D:Q:D:Q:D

Decisions-decisions!
 
HMMMM Do I build my SE-5 plan and bust your butt, or the D-8 and become your wingman??? Lee

Well.....I have an SE5a and a DVII.....so either way works for either plane...LOL

I also have a DR1 in progress;-)

A Bristol fighter to build too....

Hmmmm looks like I have some decisions to make also....:D
I guess I better stop being lazy and get to work building...

robinairerc 01-17-2008 11:19 PM

decisions!
 
Hmmm-- maybe my Sopwith Tripe--- I'll think of SOMETHING!! Lee:confused:

Beware the Hun in the Sun! :eek: Wait a minute. I am the Hun in the Sun!!! :eek::D I will put the wind up your tails and fill you full of lead! Martin

WWI Ace 01-18-2008 12:28 AM

Just make sure the lead isn't in the seat of your britches or your slow rear end will get shot down!! By no other than the triplane flyin' Texican!! Steve

Good one Steve.:)

Keep on Dreaming!
 
You Texicans and Californians are having pipe dreams again! :rolleyes: It's well known and established that certain WWI pilots, located in the war choked skies over South Jersey, possess superior flying skills compared to any Texican or Californian fledgling pilots. Why just look at my kills! :D I hold you red triplane pilots in complete contempt! :eek::D Von Martin

Von Martin.........Priceless!!!!!

BUCKSHOT 01-18-2008 02:50 AM

my RED bi-plane will be here tomorrow,WE PLAN ON USING THESE FOR SONIC COMBAT....HEY YA'LL WATCH THIS

WWI Ace 01-19-2008 01:58 AM

I've heard that the WWI pilots over NJ just choke!!! Steve

Got My First Bipe
Lanier Dvii,whats Agood Watts Per Lb On A Bipe
Io Have A 250 Watt Dualsky

Oh Yeah!
 
You Texicans will choke on some bullets!!! :D Martin

300 watts per pound.....haha just kidding.


120 or so would likely be good for scale flight....personally I like them to be way overpowered though

AeroDude 01-19-2008 03:33 PM

Murphy,

120W/lb is actually overpowered, the basic rule of thumb for power/weight ratio is:

50 - 60 Watts/lb minimum

70 - 80 Watts/lb for scale flight

80 - 100 Watts/lb for mild aerobatic

100 - 120 Watts/lb for unlimited aerobatic

this rule has worked well for all my planes including the bipes and tripe

Yep...I over estimated a bit.:)
I looked up my E-flite literature...It says:

70-90 watts per pound for slow scale fight.
and
90-110 watts per pound for fast scale flight.

Personally I prefer more power than that.;-)

MurphyBub::I agree,Sometimes you need "more power" to get your leg over the fence with things go south at one mistake high, if you like less power, thats cool, just keep your thumb out the throttle! I like fly'in "scale" most the time but have'in it when you need it can save your butt, ( and plane), Like you I always over-do a might,,your bub, steve

AeroDude 01-19-2008 06:46 PM

Murphy,

I mostly build scale these days, currently working on a 1/6 scale J-3 Cub diecut kit from Sig that dates back to the 60's, adding as much scale detail as possible. It requires a little more skill to fly some aircraft at their scale power/weight, I agree it's a good idea to build in a little more power to get out of trouble. My Fokker DR-1 is very true to scale it's touchy on takeoff and difficult to land. If you attempt a turn during takeoff it will torque over and nose in as the full scale one's did.

to approximate the scale weight you divide the actual full scale weight by the cube of the scale.

if you use the same correlation for power you get little lower Watts/lb than the rule of thumb.

1Hp = 750 Watts

for example:

scale weight for the cub is ~ 6 lbs

the standard Cub is a 65 Hp

65 Hp x 750 Watts/Hp = 48,750 Watts/(6)**3. = 225.69 Watts

so if the cub finishes at 5 - 6 lbs the scale power should be 38 - 45 Watts/Lb

All that extra power sure helps when you accidentally stall without sufficient altitude!!! Steve

Stall
 
Not if your tail is full of lead Steve! :D:eek: Martin
