Make sure you get the C of G right and you will be a happy pilot. This is a great model to have in your collection. It is definately worth the build process (which I enjoy).

Thanks. According to the instructions, the CG is in the middle of the front spare. Is this still correct? Some models don't seem to adhere to the published CG and must be moved fore or aft a bit to fly right.

Mine is the 52" balsa version and it says the middle of the front spar so that's what I'll go with. I elected to install the servos on the tail rather than having very long control rods, so I'm having to add much more weight to the head. I may regret that move.
I originally ordered the foam one but decided it didn't have the "look". Marston was generous enough to send me the balsa kit and deduct the cost of the foam plans from it. The 80" one is just too big for me.

I think you are right ! I had no trouble with the long pushrods.

Well, maidened "Pteri" this morning. It flew wonderfully. Balanced as per instructions and needed a couple clicks of down trim to level out. Launched with ease, does loops, rolls nicely and had this really eerie whistling sound on a high speed fly by. Belly lands so nice. It even glides not too badly, either. On a 2200 mah 3s battery, I can get about 7 minutes of safe flight time.
Second flight, the same. No problems, no incidents. Wind was a slight breeze but because of the sleek design and the power of it, I think it should be able to handle some wind no problem. It was a real eye catcher at the field. Several vids taken but none by me so will have to wait till they edit and put on YouTube, then I'll post here. One fellow was so taken by it, he's going to get the 80" one.
The only thing I'm going to change on it is to install an ON/OFF battery switch on the side of the body so it's not powered up the whole time I'm putting the wing on and until I get the wing off. The tail servo weight and the additional weight in the head didn't appear to affect the flying characteristics at all. She's a thing of beauty.

Glad to hear it went well. I agree that this plane handles wind wonderfully. I like the idea of the battery cutoff as it does take a minute to put the wing on while armed.

All,
With. The 80" version having a breakdown wing, I don't see wingspan as a reason to stop someone from building the 80" version. Just build time and landing room...

Great vid! And I have never heard that song before either. Interesting.
I really like your idea of having the eyes light up to show the battery's connected.
If you don't mind, I'd like to copy your idea on mine when I build it.

How much would you say the entire Ptero cost to build, start to finish? Include motors and electronics please.
