One more thing...on the wing tip tank things...sand them on the top and bottoms to match the surrounding wing surface...do not sand or change the end of the wing part. I just sand the tanks on the top side and bottom side....you will have to match the leading edge contour area of the tank to match....this will reduce a lot of drag and it gives you more lift..not much but you will see a diff. on landings...much easier.
If you need pics I can do that...I have a old fuse in the hanger.

RE: FUNJET
hi, kind of a newb ? but i am getting ready to start building my fj..and i am wondering what paint i can use to paint it

On the EPP foam paint does not stick well any way.
servos...Hitec 65 mg will do the job and last a long time. Expensive yes but you do not want to guess about servos at any speed over 80 mph.
Make sure to balance your prop and check the watts/amps on 4 cells as to not toast the ESC...80 amp ESC would be the best choice....I always go 10-15 amps above the motor max amp draw just to be sure.
Post some pics

What type of monocote did you use?? The regular monocote or a low temp?? and no problem's with the foam melting??

Use as low a temp. as you can to get the foam to stick to the foam. I don't wrap the wing...I cut to fit the top of the wing then add a front cover..either tape or more covering.
Take your time and exp. don't use to much temp.

RE: FUNJET
risky,
Which main parts have you purchased already?
I'm referring to MOTOR, ESC, and BATTERY.
I saw your list on last page...is that a planned list or have you bought the parts?
If you bought some of the parts which ones?
What is your speed goal? As fast as possible? Or above 150 MPH? Or above 130 MPH?

RE: FUNJET
theb1bman,
Awesome work my friend. Truly work of art and labor of love.
I look forward to seeing some videos one day.....some of them HIGH SPEED (I hope
)
Some modified and strengthened Funjet builds have ripped off the elevons at above 130-150 MPH.
I doubt that could happen to your built at 200 MPH.
I hope a 4S-5000 can fit in there like a regular Funjet with some foam trimmed inside.
Would be great to see someone get the world speed record with one of your C.F. Funjet airframes.

I think the elevons will stay on and lots or room for batt this is the set up I will use as soon as I get the motor I have every thing els
1512 2d NEU motor 2 3 cell 3900 to make a 6cell 100 amp ice 5x5 prop. all this come up to 1800 watts 50,000 rpm on the prop and over 200mph on the prop speed
It fly's well on 3000 kv and 2200 3 cell with a 6x5.5 pro but had to put in a lot more expo very touchy on the sticks

oh ya one of my flying buddy's had the same set up in a foam funjet and just over 1/2 throttle he lost more than the elevons both wing ripped off right in front off us looked way cool then he look over and said to me I need a CF one man and I said ok
keep your eye on my youtube page http://www.youtube.com/user/b1bman#g/u for the videos and wattflyer 100mph club for the Doppler

I've got a CC80,seperate bec, Bluebird servo's and a 5 cell 3000 for the FJ. I'm trying to choose between the ARC 28-47-1.5 or the 28-47-2 with a 5.5x4.5 prop. My old FJ did 119mph so I would like to top that. the faster the better....thank's

RE: FUNJET
b1bman you da man, that FJ IS OUTSTANDING and once you get it all dialed in will probably set the FJ new speed recorder and beyond.What's the weight of the empty shell and what hinge method did you use looks great,full throws with no gaps almost looks like some sort of knuckle hinge?Great vision and concept followed by excellent workmanship,kudos to you theb1bman.

the speed video will take a why'll. I am looking for a job . I need two more thing for the speed run and it is the NEU motor 260.00 dollars and I sent Castle Creations my 2 old burned out Phoenix 60 esc and they are replacing with 1 Ice 75 and Ice 100 for 130 dollars nice but there on back order but I pay for them . I think I have a job lined up but It is 250 miles from where I live and the shop I will do up a how to video as some as I get back home. I'll try to get the pics of the pivot later today and when I make the next one I'll video it all on youtube
As soon as the snow stops I plan on getting a video of it with the set up I have in it now but it's kinda [:'(] slow

RE: FUNJET
Hi guys,
I'm ready to try out a very light setup. I love my Mega 16/25/2 on 5S but I want to change it up a bit.
What's the latest on the best lightweight setup. The Microdan was the rage for a while. Is is that or the Scorpion now?
Also, will an eflight 30 amp esc work for a lighter setup? My CC 80 will come out too.
Thanks,
Steve

Rino ... my light weight set up is a Mega 16/15/3 and 40A ESC with Flight Power 3S 1,500. Its for cruising about only. Should be really good to fly. I am tired of the 4S 2,500 and 6S set ups.

RE: FUNJET
It's so easy to switch the motor and esc in a funjet I think I will keep 2 setups depending on the mood I'm in. My 5S setup is fast but you have to fly in really big circles.
How do you think your 16/15/3 mega setup compares to to the microdan stuff. It seems like you would have a little more power but come in at around the same speed, i.e. 110 - 115 mph.
