fwiw, i always sand lightly & clean both surfaces prior to gluing.
Thanks Sonicj......that's what I needed to know.

thanx leadfeather! and thanks for the design, it was a fun build! the foam is 1/2" owens corning foamular. seems fairly tough as i have planted it nose first into the ground a couple dozen times with no major damage.

not sure if its over weight or not compared to epp... i guess i need to weight it! a servo died on the last nose dive. i think i have way too much travel on the elevons as it was pretty easy to spin it into the ground on launch! anywho, heres some early pics of it. motor has changed since these photo's were taken. cheers!

The key to low air speed is low wing loading, and also the ability to fly high A with good control. Adding the rudder to the SuperFly helps with the achieving better high A control. Reducing the wing loading would be easy compared to my build, but you might trade off some of the high speed ability; not necessarily a bad thing, just a choice.

Going smaller is good if you can do it without increasing the wing loading. Going smaller and lighter can add significant electronic component cost.

Here is my list of hardware I used and respective costs. I would love to be able to find smaller/lighter stuff; especially servos; at comparable prices.

24 gram motor, $8.95 , http://www.hobbycity.com/hobbycity/s...trunner_1500kv

Motor mount, $1.20, http://www.hobbycity.com/hobbycity/s...ff_Mounts_10mm

Prop, $1.20, GWS 8x4 available widely

Prop adapter, $1.99, http://www.hobbycity.com/hobbycity/s...pter_&_3_bands

ESC, $11.95, http://www.hobbycity.com/hobbycity/s...eed_Controller

Servos, $3.49 ea , http://www.hobbycity.com/hobbycity/s...ec_Micro_Servo

Reciever, $19.95, http://www.hobbycity.com/hobbycity/s..._4Ch_72Mhz_(v2)

Servo extension, $1.10, http://www.hobbycity.com/hobbycity/s...idProduct=3835

Control horns 3ea, $.19, http://www.hobbycity.com/hobbycity/s...=Pin_Horn_9x13

There is a cheaper and lighter 10A ESC, the "Supersimple", available from HobbyCity, but I haven't tried it yet. I have used the bigger version of this ESC with no trouble.

A 15 gram outrunner would probably be more than adequate for indoor flying and another good way to shave off some weight.

BTW the components listed above are also used on my Yuk54, LevJet, SloFly28, and 22" PBF.
Are these still the suggested parts list?
Anyone have a link for the motor mount as it seems dead now.

Thanks.

Here is the link for the stick mounts.

I updated the parts list at the beginning of the thread with this link too.

Thanks for the update.

How hard is the Firefly for a RC newbie, flying wise?

It isn't a hard plane to fly, especially if it is trimmed properly. How new are you to RC? Any flying experience?

I did a little RC as a kid, built a full balsa Kadet trainer, etc. Also my father built and flew ultralights so not new to the general concetps and flying planes in general. I'm currently getting back into it now and have a mSR heli, just getting it under control, learning to hover and some basic moves.

The firefly looks like a new build, which interest me to get started with EPP as much as the flying, but I'd like something fairly on the simplier end for flying to start. I plan to get an Ember 2 for learnign a bit more plus teaching my daughter on, so the firefly would be a second plane of sorts for additional learning.

With your background you should do just fine with a FireFly. It is easy to build and to fly, yet is quite capable of some cool aerobatics and handling some wind. Best of luck!

Thanks again. Ya that is what confused me, I've seen videos of it flying slow and easy and then some of it doing some wild move :-)

Nuke em and lets fly...
Agree, the best of both worlds. I have a slow Firefly with a 2S 500mAh and a super fast (Outside) 3S 800mAh Zummm Zummm. And another one with lights, and another one with...etc.etc.

Because of this design I have more Elec. stuff then glow now, what's next Lead? I'm almost out of green...

What size lipo are you typically using on this setup?

My preferences:

Indoor 2s 360 mAh, battery all the way back, nice and light and floaty

Outdoor 3s 1000mAh, battery towards the nose especially if it is windy, great speed and it handles turbulence well.

I've flown as large as a 3s 2200 mAh battery outdoors and it flew surprisingly well but too heavy for my liking.

Can this be built out of 6mm depron instead of EPP without any changes? The LHS only stocks depron here, EPP is hard to find. Wondering what if any changes to the build would be required?

No maiden flight today. I still haven't painted my new FireFly. I have had an idea rolling around in my head for a long time now about a special paint job. I am going to try it out on my new FireFly. It will probably take me all week (a few minutes here and there) to get it done. I only hope it turns out okay since I haven't tried anything like this before.
