Well i finally got round to upgrading my f-14 from the underpowered BW motor.
I replaced the motor with the Suppo 2217-06 motor birdofplay mentioned earlier.
Tested it a couple of hours ago and what a difference it has made!

I can say this servo works well on the standard size plane lol.
I was reluctant to spend the money on one of the HS servos so my dad pointed me in the direction of some of his old gear and there was a box full of futaba 148's, so i thought why not lol.

I hope you realize that ...
I was using that big servo on my 57" Span F-14 not the original MDC F-14 !
But Hey ... with your new motor ... WTH !

I kinda like that size Suppo on my SU-47.
it should be terriffic on the F-14

Today before gluing down the wings I stuck a piece of Rectangular CF strip
under the wings Full across and between the Servo and the Wing boss's.
I'll be adding more of that CF strip to the TOP piece as well.

I took Mikes advice and Never used nylon bolts thru the wing pivots on my original F-14
but on this larger version I'm getting nervous and may put them on it.

Bob, in the above statement, is the emphasis on ht eword "nylon"? If so, why? Is there something wrong about using nylon bolts?

No no nothing wrong with nylon bolts !

Mike just emphasized that when built light that the F-14 doesn't need them
AND so far I haven't pulled the wings off mine !

On my LARGE version I DO plan to USE THEM cuz I'm more nervous about the g's.

I've built a ~57" version that will be about 2.5 Lbs ! maybe more
depending on batteries and power set up.

Look at my pix above to get an idea of the size.

I actually put the servo in before I noticed you mentioned it which was kinda scary lol
I did notice it struggle a bit at putting the wings out on a full speed pass but i kinda expected that at the speed it was going and i'm sure the servo has seen better days. other than that its great

I suppose it's a little Crude !
Sorry, can't help but chime in.... The term 'maiden' as in 'maiden voyage' (the original nautical term adapted to mean 'maiden flight' in our use) must go back many centuries as far as ships, boats etc and I bet the term 'maiden flight' goes back to the days to the Wright Brothers, well before such 'PC' considerations..... I think it is rather good to use such a traditional expression, but just my point of view, and as it is such an accepted term, I had never consciously considered the REAL meaning behind the expression until you pointed it out.....no offence meant birdofplay. I'll do you all a favour and shut my yap now I have got that off my chest!

Hey, this is a FORUM, right ? ...
If nobody talks then it's NOT a Forum

Please step up to the microphone ...

I'm quite surprised that rampant liberalism and PC types haven't squashed the term.
Guess it's not on their radar.

CONTRA ROTATING PROPS again :-)

On second thought ...

The Contra rotating idea is not a bad one with one addition !
Mix the Throttles the two ESC's to yield Differential so I'd have RUDDER !
Plus I'd then be able to trim OUT the Beat frequency !

Hey Birdofplay,

I need to do the rudder throttle mix on another bird of mine with a Futaba 7CAP. Do you know your way around the TX? The manual only references it in a footnote under heli mode.

Just got back form 4 hrs ( a 2008 record) at the field :-)))
Flew a new 2M Crysalis motor glider for a guy .
Looks like a nice piece of work !
We got 3 flights but he needs to get bigger batteries.

I TOASTED two 2s1p 1700 Lipos in my F-15 DF ! wired for 4s1p
Whew !!! When I landed I took a look at them and they looked like
and air mattress with TOO MUCH AIR !
They were almost BLOCKING the INLETS !
These were 20C-32C lipos ! sigh ...
They eventually returned to "nearly" their original shape.
However, I am NOT going to trust them.


Haden: sorry re Fut 7cPC never owned one.

When I said I was going to try mixing for Rudder function I was
HOPING that it would be possible with one or the other of my
radios but haven't even checked to see if it would work yet.
I have a Polks Trakker III and DX-7.
My old Fut's are 7uaf and the have terrible programming.
Like an Elevonmix works but you cannot use the trims like you would expect :-(

Almost finished with my F-14, was wondering how others are securing Li-poly battery to the airframe. Are a couple of 1x2 inch pieces of velcro enough or is a mre secure method recommended? Thanks.

Bad Dog,

I don't have this particular F-14, but I have a few similar ones, and I can tell you that I would not rely on the Velcro alone. I have had the battery ejected like a pilot when doing high G maneuvers. I watched the battery fall to earth while the plane now with no controls landed in a nearby tree. I was lucky. I have since made a simple Velcro strap that goes around the battery and some part of the plane body. This method is a sure thing.
