I flew these in the us army and flaps are a must to prevent stall at landing. we had a lot of weight on ours though. without the weight of an engine behind the fuse you will need to add some if electric that's why you had full trim up. all my career I wanted to see one do a loop or barrel roll!
Thanks for showing us what she can do. Hope you'll continue updating the rest of us with developments, as well as with an in depth look at the issues you had to overcome to reach this point. I saw what looked like two large batteries up front, but it appears that was to much, is that correct? Finally, I would hope that Hobby King compensates you for doing so much work on their behalf, in terms of helping them market this model, but doubt they will.
Good flight. Although you had a problem before takeoff. As soon as you pushed full throttle, your ESC lost sync with the motor. So your timing will have to be lowered. You should probably cut in a NACA duct to pipe cool air to the motor so you don't burn up a motor again.
great well done....good camera man as well ...i really love your videos....they are so funny ...with robs comments..just keep them coming....what is going to be the next plane...cheres jeff
Very interesting vid fellas! : -D thanks for sharing, MY THEORY IS... LOL! at 13:57 you can hear a screeching sound, when I heard that straight away I thought ESC! dry solder joint, I've had MANY Hobbyking ESC's go on me with intermittent noises being produced by the motor, all of which results in the motor burning out! I believe the voltage to the Rx drops too low for the RX to work properly while the motor is heating up, my theory is the esc intermittently produces gaps? in the 3 phase pulsed DC? output, resulting in the motor overheating which causes magnets to melt loose and cook motors! , I no longer buy Hobbyking esc's, I have more than 30 flying models and a few still have HK esc's in them, mainly the Blue series, have survived (dark blue not like yours) I suggest you get rid of that HK esc as soon as you can! You were LUCKY....Good save....this time
i thought that that motor was too small. You guys can probably use a motor with low KV so you can use a bigger prop. There isn't much airflow at the firewall for that prop to bite into. I'm glad that you got it back in one piece.
Hi, What motor and prop are you using? One more question, what is the all up weight of the plane (with or without batteries)? I'm considering buying it for long range FPV and I want to learn about the plane efficiency. Thanks
Curious on if you folks had an idea on the endurance factor on this airplane? I am considering building one with a DLE20 engine on it for 3+ hours duration. How did it hold up with your batteries flight-time wise? Thank you so much for doing all of the build videos; happy to say I watched all of them and you have earned a new subscriber!! Thanks!!
An incredible save, Rob!! 😱😱😱 As previously mentioned maybe a lower KV motor and larger prop to compensate for the lack of exposed prop radius caused by the fuselage? Regards. Nidge.
+RC Model Geeks Ahh... My apologies I didn't realise the motor was a sub 1000Kv. I've just seen your follow-up video and I'm astonished. The NTM series of motors are touted by HK to be their premium brand. With such a winding it's surprising it lasted as long as it did. However it still doesn't take away the skill you exhibited in bringing the RQ-7 safely back to Earth. Regards. Nidge

That was great viewing. I'll be following you lot.
lovely build, great recovery and well done for keeping your cool. look forward to the next video. :)
Thanks. it lives to fly another day!
Nice recovery and thanks for a great series
Your welcome Wayne
Good save! Man, I was thinking you were going in for sure. Beautiful aircraft. Well done.
Wow nice landing after a potentially very bad situation!
Well done mate!I enyoy all the building parts you clever made.And at least he is a good pilot!
In Germany we will say Hut ab!
Thanks Marcus :o)
Nicely done lads, great maiden and pan pan engine safe as well. Congrats to the pilot
Cheers..
Thanks Mate. My non crash record continues lol
Glad your "mush" did not turn into a tip stall, great recovery and landing.
That was not a recovery, it was pure luck that it did stall in a more nasty way.
Thanks for showing us what she can do. Hope you'll continue updating the rest of us with developments, as well as with an in depth look at the issues you had to overcome to reach this point.

2 Batteries in Parallel mainly for the cg. 1 5000 4S in the nose was not enough to get the cg correct.
Nice recovery before the dead stick landing!!! I think that the RQ-7 needs more vertical stabilizer surface.
Great maiden and vid guys, always like the new vids, hope the motor issue gets sorted
Thanks mate. I hope so too!
Pucker factor increased tenfold for a moment , nice recovery 😎
Heavy pants moment ;o)
9:25 i thought she was going down haha good recovery
Experience saved the day ;o)

Superb recovery! I don't know about you, but I was clenched for a few seconds :-)
I had a split second thought of bloody hell im going to stack it on the maiden lol
I have the same thought on every maiden and, so far this year, I've been 100% correct! :-)
You did a great job with the plane and had a perfect landing without the engine.
Thank you. Staying calm saved the day ;o)
great well done....good camera man as well ...i really love your videos....they are so funny ...with robs comments..just keep them coming....what is going to be the next plane...cheres jeff
Thanks Jeff! Whats next Hmmmm not sure! I think a manufacturer needs to send us something interesting to play with!
my pleasure...yes i hope they do ...i love war birds myself ww2 i watched your fw190 video...great ...have you ever flown a f.m.s....warbird...

I think you're right Kiowa , when you look at the size of the dead air pocket behind that fat fuse , have to get the prop biting clean air 😎
This plane needs an air scoop and seperate power for the reciever and servo's; I think it's the ESC as well.
Are you guys going to get this back in the air? Im on the fence about ordering the kit. I hope you will do another video about it.
Rob you are the man. She obviously needs lots of airspeed when dead stick. Have you worked out what went wrong?
Cheers mate. Yeah i was hobbykinged lol
Hi boys ....A great build .... and first flight ......per chance can you post a copy of the build manual in PDF format.
Its here www.hobbyking.com/hobbyking/store/uploads/548171053X50800X7.pdf
Thank You
Dangerous landing!
It is posible adding one more metro of wing to make it 3m wing spans
Just found this one mate. You should have fibreglass it.
Hi,
What motor and prop are you using?
One more question, what is the all up weight of the plane (with or without batteries)?
I'm considering buying it for long range FPV and I want to learn about the plane efficiency.

Thank you so much for doing all of the build videos; happy to say I watched all of them and you have earned a new subscriber!! Thanks!!
Thanks for the comment and welcome! Well that flight took about 2000mah out of the battery. so roughly 35-40 minutes on 10000mah.
An incredible save, Rob!! 😱😱😱
As previously mentioned maybe a lower KV motor and larger prop to compensate for the lack of exposed prop radius caused by the fuselage?

Nidge.
already down to 750kv. Don't think this was an overheat issue ;o) see latest video.

At least it lives to fly another day! ;o) A replacement would be good. lets see what happens ;o)
Can u share plans. For this
what flight times you getting on 10.000mah
awesome
How many kilograms is pi-load of this rq-7?
Shame that happened ,shwe was flying very nice there untill the egine faileure.but i am sure you will get it sorted .
