AirX,

Thanks for jumping in with the intake lip info. Looking forward to your micro F18E. Better start doing my eye excercises . These small planes sure are fun to track in the sky.

When you get around to the F35, I'd love to see your progress .

PS already have the plans, thanks!
Sorry,

I need to pay a little more attention when reading. Please let us know the results of your intake lip installation.

Depron construction Info

For those unfamiliar with working with thin depron.

All of my bends were created by first placing a strip of packing tape on the outside of the bend. If you do not do this the depron will crack/tear.
Then the bend line was scored with a metal edged ruler. Slowly work the bend along the length of the fold lines. While the tape is still on I like to exercise the bend by flexing it a few times.

All rolled pieces had packing tape on the outside curvature (similar to above), prior to rolling over the edge of my stair rails . No heat forming is necessary at this thickness (3mm).

Tape can be (carefully) peeled off after the bends/rolls are made.

Eric did you measure RPM in your microfan with you r setup?

Jorge
I can figure the rpm off of voltage and KV but I dont have any way to measure rpms ATM(at the moment). Looking at the figures from the last test on the stand it was holding 10.9volts if it ws 82% efficient then the rpm's would be 46000 or so.

When I get to builidng it I will post it. I hear you on the small fast planes that are hard to see and keep track of, I had a pylon racer last year and for me that was definitely a challenge, it flew arround 60 with a speed 400 in it with only 28in wingspan and fuselage length. Keep the ideas flowing Mr.B because we are getting into a new realm with Thomas Nelson leading the way...

Color Schemes

I'm looking for a color scheme, it does not need to be scale but I don't want it to be cartoonish. Initially I'm thinking something along the lines of the paint schemes for the early F16/F18's (red and white, I believe).

Does anyone know of any good color scheme references that I can tap into?

Thanks,
Mr. Boogie

The F-35, in time, could be the replacement for the Thunderbirds and Blue Angels, so.....

I'm thinking of repainting mine

Hi Folks,

good and Bad news,

I install a depron lip in the microfan, Run 1 test, and guess what:

at 273g the lip was partially sucked in


So, the installation of the lip yields an increase in static thrust from 169g to 270g (wich can be improved with a tougher lip).

Now I'll try two things, a new cdr motor (8mags and AaABbBCcC) #turns in doubt yet and a new lip build with a mix of depron and balsa)

Hey Kevin,

Just got my latest issue of RCM! Your F35 looks good in print .

16 oz AUW for your bird, is your power system putting out more than that? I've got a TP2100 and thought it might be to big.

Jorge,

Your numbers sound much nicer. You can also try coating your intake lip with WBPU or a thin coat of epoxy. You might also want to tack glue it with CA (foam safe) to the microfan shroud. Then let her rip.

Thanks for the link!

Jorge,

WBPU is water based polyurethane. It's typically used to seal wood floors/furniture. You can dilute 50/50 with water to a milk like consistency and paint on, let dry and sand to a smooth finish.

Lots of info about it's usage in the foamies forum.

Cool Boogie I will have to look for it. Thanks

My model is setup for max velocity which is why handlaunching is out. I don't recall what the thrust is but it is low, maybe 10oz at best.
