Yeah, first 5 props broken landing on nose from hand, and two more later on were 9x6 props hitting the pavement while trying to take off from ground. And all that without a single minute of flight

Just curious...

Is the plane rolling left soon after the throw on the hand launched nose ins? Mine is terrible about doing this. Its happened 50% of the time over the past 10 flights. I can't seem to pin it down.

My recent embarassing example at ~ 3:40 -

Yeah, thats how it acts. It rolled to the left and dived into the ground vertically.
I guess there would be no damage if the motor were at back.

With the wash out this plane has it shouldn't roll to one side without a reason.

I have flown these planes enough to suspect you are too heavy, tail heavy or underpowered. It looks like you gave a good toss.

One wing tip stalling would roll the plane to the side and that could be caused by too much throw or linkages not functioning under stress.

I have my CG back 10" and line it up with a mark on the skid. See the unfocused picture below. I like to put thumb tacks back 10" in the bottom of the wing to use as reference points to help me find the CG and balance the plane.

Not enough reflex will also make the launch more difficult. The elevons should be slightly up as seen in the second picture.

I have seen all of the FPV hardware that disrupts the air above the wing cause a tip roll, especially the flat front of a GoPro if it is above the wing. When something disrupts the airflow it disrupts the lift. What is on top of the wing that could be causing lift problems? It is part of the reason I am looking for another camera format that doesn't have the flat front of a Gopro.

How heavy is your plane when it is ready to fly?

thanks!
how much FPV camera gear and such are you putting up front ? I found it best to put the two lipo's sideways or the flatest part facing forward and keeping them as close together to the center of the wing as you can you dont want the batteries out to far on the wing like behind the motors!
so bring them in close to the center as you can so it does not tip to the left or right on take off.

as far as how far back from the nose . if they are big lipo's say 4x 4500 3s or two 5000 4s and with a camera on the noise and other fpv gear up front. the lipo's should be 1/4 inch to a half inch in front of the center spar and parallel to it, the center spar should be 10 inches back from the nose .
the lipo's should be stacked forward of each other with the flatest part facing forward.

again just a tip but keeping the 4 ends two and two of the lipo's right in the center of the wing end to end is a good idea so its not so tipsy on take off or when flying slowly.
two and two stacked forward flat side facing forward with two ends and two ends tuching in the center of the wing. for 4x 3s 4500mah or even 6x 3s 4500mah 3 and 3 stacked out forward of each other with 3 and 3 ends tuching in the center. center spar is 10 inches back from the nose with the lipo's stacked forward of it by 1/4 to 1/2 inches . my new HGG build is starting out this way!

my first mistake on my first HGG was putting all the lipo's up against the foward spar and it ended up noise heavy with two 4s 5000 gen ace . and I had made the battery bays to far out on the wings behind the motors as well. it is better to center all the weight and start stacking 1/4 to 1/2 inches forward of the center spar! this way its not so tipsy at slow flight. dont make it into a bar bell lol !

we are now talking about these take offs and left hand tip stalls that I think are cause by this bar bell efect so center the weight! the lipo's dont need to be out that far!

also if the wired ends of the lipo's are touching in the center it makes it easyer to wire them up in parallel together in to one big ass 3s. end to end and centered on the wing ,with two rows stacked forward of each other. then make your paralleled wiring harness going out to the two esc's from the center of your wing. this way the the wires out to the esc's are both the same (E=I x R) so make them equal in length! pluse you can add in a current sensor for your OSD right there in the center of the wing on the esc's wiring harness. both esc's should be wired in parallel together on that harness to gain equal thrust !

4 CG
I would install all the servo's and so on first then lay out every thing on top taped down to see where you would have the lipo's placed so your CG is 10 inches back.
inclued every thing that will be on the plane cameras and such to get a good reading of where your CG is with every thing taped on . install the motors and tape the ESC's where you think you want them . mock it up first before you start digging into the foam! draw out lines where things will go! then when you have the CG at 10 inches back draw out lines where each idem will go then remove every thing and dig in . make sure you have extream taped and laminated it first! read throu this whole forum as well !

if for some odd reason it turns out tail heavy just stack a nother set of lipo's in front of the others lol leave room for this HGG CAN LIFT A BRICK OF GOLD OFF THE GROUND !

I posted this originally in the reaper forum, but I was notified that perhaps this thread would be better suited for my questions.

I am wondering a few things.. I have recently purchased and will be assembling a pusher Hercules and I am under the impression that it is basically a Larger version of the Deep Reaper XL. Since I have never flown an all wing model and have looked at many different videos of the impressive things that they can do, I am 100% interested

I am going to be designing this to carry close to 6-7 pounds of weight. I know the idea is to build them light but I have a want/need for ultimate air time. My overall goal is to achieve 2 hours if possible and cover a distance over a couple miles with fpv gear. Most of the flight I would like to have autopilot to way-points that can be updated while flying, rather than at the beginning of the flight, so I can use a pan and tilt camera with a head tracker to look around. Once the batteries get to about half charge or when I want to end, automatically turn the plane around and come home.

I have been looking at different batteries 2s 3s and 4s (still not sure what voltage is best), fpv /osd/autopilot/tracking equipment etc. I'm also not sure what kind of motor to use or what prop to use. I realize that a bigger prop will draw more amps out of the batteries and make the motor work harder and once you pass up about 3000ft with a standard 2.4ghz receiver transmitter you are going to loose control of the plane.

Currently I am looking at these specs to start:
2x Turnigy nano-tech 8400mAh 3S 40~80C Lipo Pack
2x T-Pro MG90 (Metal Gear) Servos
NTM Prop Drive Series 35-36A 1800Kv / 875w
TURNIGY TRUST 70A SBEC Brushless Speed Controller (don't know the difference of BEC)
No idea for a prop.. Possibly a 9-6
DX6i 2.4GHz transmitter with AR6200 receiver or equivalent

Any ideas on how to get the range/duration I'm looking for would greatly be appreciated. I am new to FPV and am very excited at all the technology, unfortunately I am on a budget and lack some very crucial knowledge about video transmission.

I look forward to joining the many thousands in this sport!

best video receiver http://www.readymaderc.com/store/ind...roducts_id=629
use channel 4 on the receiver for 1200mhz

http://www.urbandrones.com/12ghz-yag...ctor_p_99.html comes with sma connector , this antenna is good to 60 miles out

http://www.aliexpress.com/product-fm...olesalers.html you must replace the n connector with a SMA connector for this antenna to plug into the receiver like this http://www.ebay.com/itm/SMA-male-cri...item4156e9c288

http://www.dinodirect.com/Wireless-1...w.html?cur=USD
remove the video transmitter from its case. its case is not needed if wind is blowing by . do not use the cheapo receiver that comes with it! use channel 7 1200mhz

Thank you
The 100% EPP Pusher Hercules is already for sale but not on the web site yet because we don't have an instructions set finalized for them. Mike has them on sale for the first round at $149.95 plus shipping including a 6" extension, laminate and hardware. This is the updated version with a little more sweep to help with the CG location and stability.

E-mail Mike at the website and he will see what he can do for the best shipping price to your location.

One of our delays is some of our testers are trying to get them to come apart into 3 sections for transport since the plane is too big for smaller cars. The idea is to put servos in the outer panels and try to keep most of the electronics and batteries in the middle to keep on site set of the plane as simple as possible. We realize that there will be some antenna connection plugs and other parts that need to go in the outer wings but that should be simple with some of the plugs that could be used to combine all of the electronics, including servos, into a single plug.

If you want to help us design the wing to take apart into 3 pieces let us know. We can cut the plane different so it can be glued into 3 equal length sections. We are not providing the tubes to divide the wing into 3 sections but are providing the fiberglass spars with all the kits as usual.

These are sweeeeeeeet planes. I love the nose mount motors on the Hercs and all the fun I have had with taking off the ground but even I will admit the pusher Herc may be one of the most amazing planes in the air I have flown and more efficient for FPV. It glides very well and has a good low end speed but will still go fast when desired. It is going to be a hand launch plane but launches easy if you set up a grip under the CG.

Lee, for the pusher you recommend the 3536-1800 KV with a 3S and a 9x6 prop. Is this the motor you are talking about:
http://www.hobbyking.com/hobbyking/s...dProduct=15169

Also I don't have experiences with prop savers, but I'm concerned about prop clearance on landings. Is it save to use a prop save for such a powerful motor/prop combo, or is it better to use a folding prop (which one?), or should I forgo both and use a std. prop?

Is it enough to use a 60Amp Esc, or do I need something bigger? All Turnigy Plush ESCs (60, 80Amp) are out of stock at Hobbyking, any other ESC you can recommend for this motor?
