I kinda like the noise! I live in a small valley and the echo is so cool! Mine is built and painted. Just need to finish electronics installation and details. I did add aileron. Really excited to get this one out. I have flown the F-22 to the point of being almost worn out!

Sorry guys, been away for a few weeks....

thanks jeffsch for the info on the slot shape, I flew twice just with the slot shape change, it did make a little difference on my jet.

However after that, I finally figured out what the noise was, one of the push rods was vibrating within the guide hole that I setup half way between the aileron and the elevator.... And as I increased power it got a lot worse...

Now she is making the right noise!!!!

Got a few flights on it yesterday and its much better, just need to work out the dx6i trim in the air with only two servos. I can't just trim up or down, when I adjust the trim it makes the plane turn left or right.

Is there something I am missing with the mix on the tx?

I'm not too familiar with the DX6i but on my DX7 you set it to "wing type DELTA".

Then to trim while you're flying you just use the up and down trim button next to the right stick to trim the elevator and the left and right trim button under the right stick to trim the ailerons (roll).

Hope this helps.

Hi everyone, im new here and new to RC in general.
I have never built or flown an RC plane, just a small electric heli (Blade 120 SR and MCX)
I love the look of the F-18 so i just finished building one.........
I used Elmers foam board, left the paper on and covered it with clear packing tape.
Finished plane with no electrics at all yet.......... weight in at 11.5oz or 330g
how does this compare to others that have built this model, and will it fly with the 2200kv & 30amp ESC , 6 x 4 prop and a 1320 ma lipo ?

thanks in advance

rick88ss, that's the setup it had on the dx6i, I unplugged every thing and put it all back together, then the trim worked correctly...

Repsolal,

my F18 is 440g, That's finished plane with all electrics 2200kv with a 1300mah @ 100% size in 6mm Depron

your electronics will probably add another 6-10 oz maybe more... it will fly but don't expect anything crazy..and since its your first plane......uhh.... because its so heavy it'll be a little underpowered which might make your maiden unsuccessful.. although i use foam board myself..i take the paper off then use tape...the paper its really heavy..I'd suggest either rebuild your plane w depron or use a smaller battery..or take off the paper then retape... good luck to you.

Thanks for the input
After more reading............. The F-18, heavy as it is, first build, first plane, total newb...

I decided to build a 32" Baby Blu trainer to start with !
which weighs in at 5.5oz compared to 11.5 for the F-18
Looking forward to a maiden flight in approx 2 weeks....... waiting for parts on a slowboat from china

if any of this makes any sense..
just because your f18 is heavier than the baby blu doesnt necessarily mean it will fly worse/better. YOUR f18 is a little heavy. i was refering to YOUR set up. you need to look at thrust/weight ratio. even though you are new i think the f-18 is a great first/second plane. it flys slow, it flys fast. just because the power is there doesnt mean you have to use it.

Picked up a sheet of 6mm Depron and made another.......... half the fun is making them.......... right ?
This one weighs in at 130g compared to 330g for the first one and its all painted and ready for some hardware. Really looking forward to a maiden flight before the snow comes ! Probably start with the BB then try the F-18 if all goes well.
Friends and neighbours are getting quite curious too, should be a good turnout for
the maiden, with pictures and video from 2 cams................ not too much pressure !

alright!! glad it work out for you. imo you should have your maiden w/o extra people there. mybe just your camra man.. the extra distraction might be a bad thing. then you'll have someone saying.. do this...do that... but good luck to you!!!
you should convert the $tree foam into a 64mm 4s edf .... but of course when your ready.
good luck man!

Built 2nd F-18 from Depron
AUW 15 oz or 400g
RCtimer 2200KV Brushless Motor 2826-6 + ESC 30A
6 x 4E prop
2 RC Timer Micro Servo 8g
Venom 13C 3S 1320mAh 11.1V LiPO
Km3 airfoil

Maiden was a disaster, hand throw and instant dive into ground and broke nose in half.
Yellow popsicle sticks are to repair damage ready for 2nd attempt.
I dont think I threw it high enough or had enough throttle to keep it in the air.
Will hopefully try again later today if the wind drops.

You shouldn't even need to throw it. Should zip right out of your hand. Prop backwards? Balance? Servo reversed? Check the obvious. Somtimes that's all it is-
