Have a look at some of the 28mm motors from turnigy..
what you need wil depend on your prop size..
4.75 X 4.75 needs 3200~4200KV and needs to be above 500Watts to survive on a 3S battery.
5 X 5 will need to be 2800~3200KV again around the 500W mark on a 3S
6 X 4 2200~2800Kv again around the 500W mark for a 3S

Battery will need to be a 3S 2200mah 20C (short life span) 30C prefered.
reason is just maths.
The 2200mah 20C can take 44amps continiously 2.2 X 20 = 44.
So a 30 C battery will be 2.2 X 30 = 66amps
I know my 2223 motors pull around 55amps(not good but they are tough motors)
so a 30C battery will last a long time...( good for vetran fliers who dont crash very often)
Where the $9 3S 2200 will last a few months which is fine for begining as crashes occur often and often cost batteries.

Yeah its tough on their website to find something with good characteristics..
This one needs shaft reversal but includes the X mount and prop adapter
http://www.hobbyking.com/hobbyking/s...er_2350kv.html

Power is a bit low on this one but it will spin a 7X4 prop

what about this setup?

I been doing a little research thru the forums,I was wondering why not use a EDF motor but with a prop
I found 2 guys they did, So maybe I'm missing something about this EDF motors but what about this:

http://www.hobbypartz.com/75m96-ducted-2220-2700.html

its a 2700 kv, 500W, 28mm ,78g (a little heavy) and load weight 80g

with a mount like this one :

http://www.hobbyking.com/hobbyking/s...tor_Mount.html

a prop adapter Colet type 3.17mm

and 60amp ESC (no/BEC) 3s 2200 40c lipo

Just looking at the motor you have suggested.. Yes you wont have to reverse the shaft inside the cage mout that you have spoted.
but try this motor instead on the 6X4
http://www.hobbyking.com/hobbyking/s...dProduct=11179

Its cheaper and will be in the same order when you get the Xmount.

Also why no bec? do you have a standalone?
I just ordered some towerpro 40amp esc's $11 and hard to kill.

you are right man

Agree with you.

hey what about the Turnigy SK3 series, they have this one:

Turnigy Aerodrive SK3 - 2836-2500kv Brushless its 405W

http://www.hobbyking.com/hobbyking/s...dproduct=18117

read what ppl say it about this motor.

I think I'm going to buy 2 Turnigy 2223 4400KV motor and one Turnigy SK3 2836 and see what happen.
Thanks a lot for your help and free plans bro!!!

No worries Juan, I havent used the sk motors at all.. I had looked but not read many favourable reports so I didnt look at them.
I think you will like the 2223 motor and maybe even look at shaft reversal one day.
Its a great motore.
Enjoy the plans they are there to be enjoyed.

I am a newbie and I spent this evening reading your entire thread. I have also downloaded several of the plans from your website. I really appreciate the work you have done in providing great plans and technical help to all who ask.
It seems to me that one of your videos showed you flying the "Trainer" but it did not match the Trainer plans from your site. It had double wing thicknes (KF?) and the shape of the wing was different (swept back and stepped at the fuse). It did not look like the JP1/2 but I could be mistaken. The one in your video had a camera mounted on the nose but I am not ready for FPV at this point. Your final comment at the end of this video was "Well...I think we can consider that a success".
What version of the Trainer was this??....I would like the plans for it.
Again, you do the RC community a great service. Thank You.

Hey and welcome to the thread. Yeah it was just a scratchbuilt version of what Id seen of Mike P's plans. I like the F22's V tail so that was inherited onto this model.
Yes I used a KF step on the wing and it was one piece for the top to add more strength to the wing.
Ive been mainly been working a lot recently. I work an 11day on 3 day off roster living away from home so I do play with planes after work but I dont have the resources and time to put up plans and make as many videos as Id like to..
But that will change shortly so you should see more videos and more how to's.
My website renewal is up again so there is another $50 for the year but its a drop in the ocean I suppose for what it gives to the community.

Look fwd to more plans like these soon..

Clint

Hello Bert, a little bit late but as you requested. I gave the wings a little bit more sweep and the vertical surfaces can be set to your desired angle but the image on the plans is set at 60deg.
The KF airfoil would be better as one piece over the join in the center to give it strength. Even if its joined to another piece further down the wing.
Recomended performance setoup would be either the 2218 or 2223 turnigy motors starting from 3200~4300KV with the towerpro 40amp ESC using a 2200mah 20C 3S battery on a TGS 4.75 X 4.75 prop.
Ive left out servo placement but its better to take advantage of the skids and to mount them on the underside of the wing but cut into the vertical skid to really lock them into place.
I have not built this yet but it will fly. The ailerons can be lengthened inwards to achieve that locked in place servo setup.
Unfortunately my copy of photoshop is locked out at the moment so plan quality is so so.
Please let me know how your build turns out.
Regards
Clint

Clint!
Great to see you back in action bro!
I'm sorry to hear you've been working away from the family so much.
Are you still doing rail work?
I go to your site often, to check for new work and to keep the traffic up.
Glad to hear you're still building and flying. I haven't been in the sky in months. The weather here is NOT flying-friendly in the winter, and I've been swamped with work and other projects.
I can't wait to try out that new trainer you posted for Bert.
Will you bee doing a single sheet pdf plan for it? I seem to have trouble with the jpg images for some reason. They never seem to print the correct size, even if I manipulate them in photoshop. I think it may be a problem with my plotter.
Cheers!
-Mike

Clint, thank you for the new "Trainer"! The plane looks terrific and I will start the build ASAP. I appreciate the additional configuration guidelines on the build and on the
electronics installation. I will let you know how the build goes and send pictures.
Thanks again for allowing us to enjoy your designs.
Regards, Bert
P.S.: When do you think you can publish the plans in JPG Format so we can scale it in Paint?

PNG or portable network graphics ( I think?) will still scale up or down using paint. I started using PNG files over jpg files as I found every time I save a change to my plans using paint the image would start to smudge or pixilate when using jpg as the saved file.
I do hope that it works well for you Bert.

Hey Mike, long time my friend.
yeah working away is a bummer but Im finishing that job soon.
I should fix up my registration issues for PS as the image always comes out nicer!!
As for finishing them as a pdf.. One day my friend.. one day haha!!

I hope those other projects free up and give you some time to get some rc time in mate... Without I think Id be a little bit mental....
No wait... I think I am already.
I have to get on soon and pay for my site renewal or otherwise I will just start to post the plans on here.
