Jesse,

Your proposed setup looks good to me as long as you expect your Predator to end up with a flying
weight around 40oz..

Eventually I would like to be able to put a small camera in it, such as the flycamone3 or something like that, would you suggest a slightly more powerful motor for example  http://www.nitroplanes.com/98p-mars-bl3732-1100kv-bl30a-combo.html




lejongleur -> RE: Nitromodels PREDATOR RQ-1B (9/27/2011 11:48 PM)

You might want to up the power a bit as you suggest - at 40 ounces, 200W is not huge.

However, the motor you showed a link to specs a 10x5 prop - Predator ground clearance really only allows for a 9" prop so you might want to consider a 9x6 or similar.

Hope this helps...Chris



jeskimo5 -> RE: Nitromodels PREDATOR RQ-1B (9/27/2011 11:53 PM)

I still plan on using a 9" prop.Thats ok even if the engine is recommended for a slightly larger one, right? 
Thanks for the help guys, I'm pretty excited for this



papajeff -> RE: Nitromodels PREDATOR RQ-1B (9/28/2011 2:05 AM)

Jesse,

Take a  look at these Monster power motors which might be better for you with the added weight of the
camera equipment.

jeskimo5 -> RE: Nitromodels PREDATOR RQ-1B (9/28/2011 4:31 AM)

 that particular motor was sold out so i substituted  http://www.nitroplanes.com/98p-mars-bl3738-1300kv-bl45a-combo.html which had similar characteristics. 




jeskimo5 -> RE: Nitromodels PREDATOR RQ-1B (10/12/2011 8:16 PM)

 Well it's been a while since I checked in. The predator model I bought came from www.generalhobby.com. It was a tealish camo color, seemed to be similar to the nitoplanes model.
 IT CAME WITH 2 LEFT WINGS! ARG
Additionally, there were a variety other problems with the model (including a misformed fiberglass cowling)

Anyway I sent it back and the guy is supposed to be sending me a different predator model by a different manufacturer, hopefully it comes with one wing for each side :)

PapaJeff.......

I am new to the forum.  I followed this thread over here from the Nitro site.

I am considering getting one of these predator electrics.  But all models seem to be out of stock.
I read alot of the beginning of this thread and it seems to be an ongoing problem.

But I have another question.  There seems to be three models offered at three different prices.
$79.95 for mod.#90A166_ARF_RQ18,  $74.95 for mod.#81A166Y-Q-1, and $49.00 for mod.#81A66-Q-1.

I looked at the differences in each description.  I thought the small monetary difference between the
first two "might" be only because of the color scheme. But the $49.00 model has me stumped!
I do not see any differences in the model descriptions other than color.
What could be the reason for the big price difference for the $49.00 model?
And why do they seem to have a supply problem?

Any help would be appreciated.



papajeff -> RE: Nitromodels PREDATOR RQ-1B (12/3/2011 2:09 PM)

Teddy,

I just looked at the Nitro site and the three Predators do have me confused, too!  I tend to agree with you that the difference
between the first two is just color, desert camo vs. green camo.  Now, the $49.00 one sure looks just like my original green
camo version and I cannot figure out why it is 25 bucks lower.  Since they all are "out of stock,"  I would suggest that you contact
Nitro to see if they are expecting a new shipment of any Predator models in the near future.



Teddy da Bear -> RE: Nitromodels PREDATOR RQ-1B (12/3/2011 6:46 PM)

I have already written to them last week......still no response. Do they go into hibernation in the winter like us bears?  lol



whirl10 -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 4:10 AM)

Can someone help me out?  I cannot find a decent way to mount the cover on the back...what covers the motor/esc.  Email me please.  whirl_10@hotmail,com



papajeff -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 8:33 PM)

I just took a look at my Predator and all I did was to place the rear cowl and then to attach it to the fuselage with
4 small screws.  I think that you can see one of the attachment screws in theses photos.  It basically just covers
the motor and ESC and provides cooling ari for both.  I hope that this helps.



papajeff -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 8:49 PM)


Concerning the nose gear placement, I just mounted it as the directions indicated and never made it
stearable as I found that I did not need it to be.  Our flying fields are grass and the Predator took off in
such a short distance, that I never had a problem with the nose wheel.   I did attach a slightly larger
nose wheel as you can see in the last photo.



whirl10 -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 9:00 PM)

Awesome.  I didnt need to have any extensions on my motor as it was long enough w the prop adaptor.  SHould I be worried about it beig too "big?"  I tested the AMP and watts...it was right at 19 amps and 200 watts.  Sould be good for a standards weight...I havent weighed it but Im using no extra parts.   



papajeff -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 9:07 PM)

Whirl,

It's not so much physical size of the motor that matters, it's the wattage which you are aware of.  Also,
the plane is so light in it's construction, all balsa, that I did need some extra weight in the nose battery
compartment to get the correct CG.  You can see some of the little lead weights in these photos.

Also, I found it helped the air flow over the battery to open a small hole in the nose as you can see.



whirl10 -> RE: Nitromodels PREDATOR RQ-1B (1/9/2013 9:23 PM)

Cool.  Ill do those mods.  is the CG spot correct in the manual?   I got 200 watts with my tester so I should be good, no?



whirl10 -> RE: Nitromodels PREDATOR RQ-1B (1/10/2013 4:44 AM)

Last question:  how are you supposed to mount these crappy wheels? I ordered the light weight ones you said but as bet I can tell, you just use a washer on each side of the wheel and screw it tight?  They wont roll...the front wheel is so tight on the bar it wont roll at all.  grrrrrrrrr



FlybyRC -> RE: Nitromodels PREDATOR RQ-1B (2/20/2013 6:27 PM)

Ok,

I have had a nitro planes 64in Predator sitting around and its about time i got it in the air.

I have read through the forums with papa jeff and it seems i can not figure what the best motor would be. you say A22-20L, but i look them up and all i find is a hacker style motor. any suggestions.

Can anyone paste some links to some motors.
thanks

rjmanzuk -> RE: Nitromodels PREDATOR RQ-1B (2/20/2013 7:39 PM)

I've had great success with my Electrify RIMFIRE brushless outrunner, GPMG4640, 850rpm/volt (45A constant/55A surge), 666W const.; coupled with a, Extreme Flight Airboss Elite 60A ESC, and a Thunder Power 3800mAh/45C battery. With that rig, my preferred propeller is a 3-blade Master Airscrew 11 X 8 .
