Thanks, Guys

I'll get some more specific pictures, and specs tomarrow.
I read your build on the 80" pyerodactyl great job. I should be starting on
mine in about a week, waiting for the hardware.
I used the recomended Ultracoat for covering, also the recomended servos.
The motors are 400XT's with two BP 10 Amp esc's, and two 6" Y harneses,
one for the esc's, and the other for the aileron servos I have a few batterys
to choose from, not shure which one I'll use, I'll let you know after I fly it.
the rest of your answers are in my above post.
Thanks, but this is your build. How is it going?

I will add the finnishing touches after I have it flown, and tweeked out.
Here is one more picture for you to look at. Tugboat is this better ?

I wasn't really that serious...

Although I have to say that your 'dactyl is starting to look a bit predatory...

It will be interesting to see what Jim comes up with for the 'colour scheme' - I have a suspicion that there is a wide range of 'character' available on these 'aircraft'.


PS. You will have to post some info to the 80" thread when you start.

You will just have to wait and see what I have planed for the 80"pterodactyl.
I'll give you a hint, I have an 8 ch radio, and plan on using all or most of the
8 channels in my 80" bird. I'll keep you posted when I start. It looks pretty
good for Sunday to test out my 52" bird, if & when I do I'll post some pictures
of it in flight (got my fingers crossed). I learned alot from building this one I
may just have to order annother one as there are some other modifications
I would like to try, and this 52" kit was a blast to build, and went together
pretty fast. But first I'll wait to see how well this one flys.

Building is slow with 4 kids
I was getting frustrated with my aerobatic plane so I built a Fliton Mini Inspire. Problem solved.

I've had the Park Strafing Mustang I've been building for about a year and all I have to do is hook up the elevator linkage and shoehorn a receiver in there.

My 12 year old's interest in building comes and goes. Lately it's been gone. I'll get back to Petrodaktyl soon.

Meanwhile, I'm very pleased to see everyone sharing in this thread. It looks like such a cool plane, I'm excited to get to work on it.

I've had my 52" Pterodactyl kit for 3 weeks now. I haven't started on it because I wanted to get all of my electronics for it first. I just bought 2 Hacker A20-26M motors and 2 X-12pro ESC's. I still have to get my servos for it. In the mean time, I have been building the Foamie version of the balsa kit. I have half of the foam cut out for it. I have all the required electronics for it I just need more time to work on it. I will be starting a build thread on it, I just don't know where to put it in the forum. Any suggestions?

Ralph V and JimTMich - Both of your birds look really good. I'm going to cover mine in Purple monocoat as the primary color.

TugBoat - Your 80" looks really cool. I may build one of those next

Ralph V and JimTMich - Did you both put your ESC's in the center wing like the pics in the build manual? Or did you put them further out in the wing so you didn't have to make motor wire extensions? I was thinking of putting mine further out in the wing so I didn't have to make the extensions and just make extensions on the battery wires.

Ralph V - Can you post more pics of the servo doors and trailing edge mods you did. The servo doors look really sweet!!

this defenitly on the "wish list".
anyone who has one and is not going to build it, shoot me a PM.

Yes I mounted my ESC in the center of the of the wing like the pictures in
the construction manual, that way if I have a problem with them I can replace
them without tearing into my wing. I have a BD-5 with motor wire extentions,
and it seems to work just fine. As far as the trailing edge modifications, when
you get that far, review my post, and you should understand what I wrote. If
not let me know, I guess I could draw it, and post a picture of my drawing.
I didn't take a lot of pictures of my build, I was too busy building, and hadn't
really planed to do a build log on it. What kind of pictures of the servo doors
did you want? I can take the servo door off to get more pictures if you like,
I didn't cover them yet, until I have it all adjusted to what I want it at.

If it flies, I will crash it

Looking good Jim. It looks kind of like a compound bow frame sitting there. It looks like they have a pretty good motor mount worked out on the 52" as well. Hang in there. Can't wait to see it fly.

Just found this thread. I tripped across the Marston web site about a year ago and fell in love with the Ptera designs. At that time he just had the 80" version and based on the videos it looks to be too hot of a flyer for my local flying field. I emailed him asking about a park flyer version (he had pictures of smaller prototypes on his site) and am glad to see he finally produced one! Also check out his fish plane on his site, it's really cool looking too!

Ralph's certainly looks nice, I was disappointed to see that he didn't post a flight report though. Ralph, if you're still around I'm sure I'm not the only one that would be interested to hear what happened whether it be good, bad or ugly

I have been kind of busy with family stuff, about the time the weather
clears up, more family stuff comes up. I haven't had chance to fly mine yet,
but this Sunday looks like I might be able to finally get some flying in, if I
do, I'll bring the pterodactyl with me, and keep you all posted on how it
turned out. But I can look on the bright side, during the crappy weather I
was able to get some building in on some of my other projects, so if it all
goes well I'll have plenty to fly on Sunday, I even got someone who can
take pictures for me when I'm flying.

Ralph, thanks for the update! I'm actually relieved to hear you haven't flown it yet, I was concerned that you had piled it in on the maiden and didn't want to talk about it, I've been there before

Art, here's a link to the web site:

More progress

Got a little more time to set up the motor wiring and build the head and kneck.

I'm starting to get the hang of sanding pieces before I glue them together to make all the odd angles work. It's not hard, I've simply never built a model like this before.
