I also found this one at Hobby Lobby which looks very similar...

Hey,

Yeah thats does look very similar, although power is down a little if I am not mistaken it's difficult comapring metric to imperial specs
The casing looks the same, probably is equivelant to a Waypoint servo just badged differently.

As you say the retract servo is the better option as with the extra rotation you wont need such a long arm, in turn allowing the servo to generate more torque as well as the load isn't so far out from centre.

SMKN,

The elevon mixer mixes the two signal from ailerons & elevator channel to give you elevon control

Here's the link to UH, but they are out of stock at the moment. You can also get the GWS one at Tower Hobbies for around ten bucks

To convert from kg.cm to oz.in multiply the kg.cm value by 13.858

eg.: 2.2kg.cm = 2.2x13.858 = 30.488 oz.in

54oz.in = 54/13.858 = 3.897 kg.cm

Hope that helps

Whoa, this is getting good. Hey, Maybz. You know your design is a good one when everyone is chipping in to refine what they think is a great design. What!? Did you hear that? Sounded like foamie of the year sounds to me.....Yeehaww. I can hear that theme song from "Top Gun" as we speak! Hey, what can I say?! Giddy as a school boy. "I'll have you know, my aircraft and crew come first" ROCK & ROLL BABY! Sorry, could'nt resist.

Hey Chewy,

Thanks mate. I used to be a mechanical/electrical engineer and the lathes/mills all had imperial dials on them, but it's been a while so I've forgot the conversions.
Having said that I never knew this one for power conversions.

I totally agree with Stephen Shioi, Maybz F-14 should be foamie of the year.

Assembly manual...

Use a good strong servo for the sweep - the HS-45 that I am currently using doesn't have enough poop to move the wing in level flight - I have to move it while in a climb or a dive. Probably need something in the 25oz/in range.

Cheers.
I'm a little lost here. You state that the assembly manual is on the first thread. Where is the first thread located? I can't seem to find the manual and would love to build this jet. Great job on the build, jet and videos and thanks for sharing with all of us. Unfortunately I missed your sale. I'm so anxious to fly it I would have preferred buying your kit. Thanks again.

Maybz,
I've been going through this thread and I have to tell you, of all the plans I've looked at so far, yours has to be my favorite. Fly's great, looks great and as complex as it seems, it looks like it will be a build that's not too difficult considering what the final product looks like. I'm very excited about starting this build. I just had a hernia surgery but once I'm recovered I'm going to start this first thing. I can't wait to get going on it. Thanks again for sharing your plans with the rest of us.

Jim

Guys, Posting ( not thread ) 1 and 2 ( check all the Pix )
"should " be enough to get this thing together.

Afterall, The parts only fit one way.

I agree that it's well done, complex, yet easy to build.
After all, Mike wanted this to be a ONE NIGHT BUILD !
( he uses foam safe CA )
I used 5 min epoxy and some Sumo !

I had some issues with the wing swing geometry but not enough that
it held up progress. This was MY first Swing wing too.

Proof is in the flying and it PROVES itself nicely :-)

I was hessitant re the wing strength and attchments but it has proven
to be strong enough for my Aero- Shenanigens ! :-)

Loops , rolls, 8's Stalls, goor vertical, Helicopter-stall,
wings-back rolls like crazy !
I'm a happy camper !

Thank you Jim, that is a very nice compliment. And thanks to everyone else who has taken the time to post their compliments and critiques. I did my best to make it easy and quick to assemble, but it certainly ain't perfect.

Jimweda - about the manual... like I mentioned earlier I took down all of the Mk1 stuff in order to minimize confusion. I still plan to post a new Mk2 manual but until then you'll have to go by the build pics which are pretty detailed.

Coolice and Chewytm - Here is a link to a cool little program that I have been using for years now.. it's the best thing I've found for converting almost anything to anything. It's basically just a free-standing Excel program but it is really handy and best of all, it's FREE.

Another neat trick is go to google.com and type in your question.

4 inches= ? mm
66 mm=? inches
3 feet =? mm
What ever you need and it will give you the answer.

hello everyone,
i was having issues with a motor not having enough oomph, fc 2805. so i replaced it with a blue(silver)wonder 1700 kv and still the same, running 6 in props and 1000mah 3 cell 20c batt and 20 amp esc.
i have a few tp 2408. but i think it might be too heavy. i also have eflite 370 out runner.
need everyone's opinion on which motor to use.
TIA
