RE: Nitromodels PREDATOR RQ-1B

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 examplehttp://www.nitroplanes.com/98p-mars-...30a-combo.html

RE: Nitromodels PREDATOR RQ-1B
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

RE: Nitromodels PREDATOR RQ-1B
I still plan on using a 9" prop.Thats ok even if the engine is recommended for a slightly larger one, right? <div>Thanks for the help guys, I'm pretty excited for this</div>

RE: Nitromodels PREDATOR RQ-1B

Take a look at these Monster power motors which might be better for you with the added weight of the
camera equipment.<a href="http://www.nitroplanes.com/mo101brmo.html">

RE: Nitromodels PREDATOR RQ-1B
that particular motor was sold out so i substitutedhttp://www.nitroplanes.com/98p-mars-...45a-combo.htmlwhich had similar characteristics.

RE: Nitromodels PREDATOR RQ-1B
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.
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 :)<br type="_moz" />

RE: Nitromodels PREDATOR RQ-1B

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.

RE: Nitromodels PREDATOR RQ-1B

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.

RE: Nitromodels PREDATOR RQ-1B
I have already written to them last week......still no response. Do they go into hibernation in the winter like us bears? lol

RE: Nitromodels PREDATOR RQ-1B
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

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.

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.

RE: Nitromodels PREDATOR RQ-1B
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.

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 flowover the battery toopen a small hole in the nose as you can see.

whirl10 01-09-2013 01:23 PM

RE: Nitromodels PREDATOR RQ-1B
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 01-09-2013 08:44 PM

RE: Nitromodels PREDATOR RQ-1B
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

RE: Nitromodels PREDATOR RQ-1B

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 isa hacker style motor. any suggestions.

Can anyone paste some links to some motors.

RE: Nitromodels PREDATOR RQ-1B
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 .

Really happy to have found a build thread for this plane as I am going use it as my winter project.

papajeff 10-11-2013 03:27 AM

Shoestring, good luck with your build and let me know if you have any questions.

bbells 01-17-2014 05:34 PM

Thanks for all the postings! I am in the middle of my build and can't seem to find a motor. The A20-22L is no longer listed on Nitroplanes. Tower has no part number GPMG4640, must be discontinued. Does anyone have an idea of which Turnigy motor would be good? I have an Eflite 480, but I think it may be too heavy and too many watts. I have spent hours looking for a motor - So maybe I am overthinking this. Any help would be appreciated. Thanks!

bbells 01-18-2014 10:05 AM

The 480 motor is part # PKZ4416. I think it is a lower power 480, probably closer to the 450 or 400.
I should add that I am mainly concerned about the weight of the motor at 87 grams (3.1 oz).
Do you guys think this will be too heavy with an 18a esc in the back with it? The fit with the rear cowl seems to be ok.
I am sure the power is ok. With the prop I am using (9x6 pusher), my watt meter registers 155 watts and 14 amps. Probably be a little more when flying.
So, I have read that some people have had problems when there powerplant got too heavy. What do you guys think? Is this setup worth trying?
Thanks for any info!

This has been a great thread. I hope some of you with predator experience are still around...? I just received my nitroplanes predator (secondhand) and am hoping for some advice. It came with no motor/esc and has had some interesting modifications made to the engine mount/wall at the rear. Ive attached some pics to explain. 4 mounting holes have been added to the wall (with threaded inserts) but they have not been centred - see pick. There is also a 'spacer' block of wood that seems to fit in with the holes.
Im trying to work out a) what motor to use that will be the right length to fit out the rear of the cowl, and b) how to attach it given the unusual mod I've described?
I'm still a noob at building so any advice would be hugely appreciated?

dwhall47 08-30-2014 08:39 AM

Help! I just got the Predator from a club member...it is partially assembled, but no instruction sheet.
Does anyone have one they could scan/copy, or somehow get to me?
If not, I have a number of questions that I need answered.
