Fiberglass MQ-9 Reaper with 2.5m wingspan

This model is big! 2500mm is impressive by any standard, yet the model is very practical, for instance the highly efficient balsa wing is removable for transportation. This model is highly unusual being both a scale model and a purpose built FPV/Camera platform. The Reaper UAV is a development of the Predator and represents the latest in cutting edge military technology, it is also much more than a mere surveillance aircraft, with its armament of Hellfire missiles and laser guided "smart" bombs, it is a hunter/killer with an impressive combat history.


Wingspan: 2500mm
Length: 1080mm
Wing Area: 32.5dm2
Wing Loading: 76-83g dm2
Airfoil: Eppler 374 Mod
Weight: 2500g~2700g


This MQ-9 comes as ARF, the following is required to complete this plane:

5~6 Channel TX/RX
36~42 Outrunner or Inrunner Brushless Motor
40A~60A ESC
2 x Standard Servo and 4 x High Torque Micro Servo
3500mAh~4000mAh 3s or 4s Lipoly Battery


For FPV use, this model obviously ticks the boxes, its difficult to argue with the design of the Reaper! There is plenty of room for FPV/Camera equipment, the scale under-slung camera pod is supplied in such a way that it can be fixed or made rotating with a little effort and comes with glazing. For FPV use obviously the model weight will increase and you may want to consider a 4s set up, prop range is 11"-12". However you fly it, this is an impressive model in every respect and is bound to be a talking point wherever it is flown.


Available from Hobbyking for US$ 100.36, see the product page for details. If you stay on the site for a while, a one-time offer window appears to budy this plane for US$ 94.96. Price may depend on your membership level at the shop.

Is this the projet mq9? It looks exactly like it. I heared it doesn't fly well

This has been out ages and has a wing loading 0.18Oz/in² which pretty much rules out this as a trainer craft (for beginners). It looks great but according to the RCGroups threads flies rather more sedate than expected because agressive moves unsettle it (not that hasn't been seen so far in all the UAV models though just search for PapaJeff).


As model the looks are great and the P&T camera dome at the front could be good. Shame its 30Oz too heavy really.

I would appreciate more a "real" uav/fpv model with stable flight characteristics that this scale model from HK. Something like a good twin boom pusher with plenty of space and more or less that price. I was considering for a couple of seconds this HK offer… but no. It’s a no go for UAV and/or FPV. It seems that the idea that the perfect drone is a scale version of a real drone is hard to die. But this is a rc scale model of a drone, not a rc model drone.

Yes, this came out a year ago from Nitroplanes. We've had a bunch of reviews and buildlogs here already. I've got two of these models, but I only use them for display (never flown). Here is my comparison post on the big and little ones that Nitroplanes sells.

I agree with Marco....
Comment by Ritchie on June 18, 2011 at 8:37am
Indeed Marco it would seem that scale UAVs are just bad but as of yet we have only seen predators, reapers and globalhawks. I can't wait for the sea avenger, X45B or some other ones finally arrive. Swept wings and flying bodies should help the scale thing

Has anyone put a gas (2-stroke) engine on this?  Does anyone have any information on what poly gas tanks fit this thing, and how much flight time they can get out of it (gas-powered, not electric)?  Thanks!

Getting the right propeller (related to its real rear airflow), be sure to have very well balanced wings (widespan, detachable) and you add the mass centering and these 3 topics must be very well treated as any plane, to get good result.

Does anyone get an excellent result with this model?

I have been slowly working on this airframe. To be honest I am pretty worried about how it will fly so I am going slow with the build to make sure it all right.


Here are some pics.
