Yeah, well, what can I say? I'm on social security disability and have to make every penny count, hence the web surfing and considering all of the options. And the one I got is very similar to the Passer, except it has dihedryl . I figured it would be easier to fly. And in truth, it isn't the plane I intended to buy, I made a mistake when ordering, but since it's pretty close to what I wanted, except for the color scheme, which is pretty garish, I'll make the most of it as I don't want to go through the nightmare of sending it off to Hong Kong for an exchange. Even though their Ebay store says "US", they are sending them via Hong Kong post. I was very surprised to get it when I did. Thanks for the constructive criticism, it's appreciated.

Sorry, I did sound sarcastic, huh?

I typed in tx 2000 2 meter into even Google search and didn't come up with much. If there's some other names of the actual plane, perhaps there's already some threads here on it with good info?

That's the only name I have for it - here's a link to the page. I picked this one because it has some dihedral, 1.5 degrees, and figured it would be easy to fly. And yeah, you did sound sarcastic, lol, you're kind of right though, lol.
I just googled it and there isn't a whole lot out there, but here is the closest thing I found to a build thread:
http://www.rcgroups.com/forums/showthread.php?t=1507043

I haven't even read it yet, but it hopefully has the info I need.

Thanks for you help everyone!

I know very little about electrics, but what I've surmised thus far is that approx 150-250W should be great for this Passer-ish bird. Lots of guys use bigger motors because they like 15 second vertical climbs to altitude then shut down. (I'm the type to use what I have and if I could rig something up to not spend more money, even at the expense of performance, i'll do it anyways...i'm a cheap sob!)
A quick search of your Scorpion numbers didn't reveal an exact match, but a 2221 is 525W which would be super-overkill IMO.

I assume you've seen at least one Passer X thread such as http://www.rcgroups.com/forums/showt...light=passer+x
in which you can get many different opinions.

Joe ... I truly do not want to sound sarcastic, but you seem to be a bit lost about all of this. Sort of like buying a horse and not knowing how to put the saddle on it.

Here is the link to the R2 manuals site....

http://www.r2hobbies.com/manuals/


I believe this is the plane you bought, the Raptor TX 2000?

http://www.r2hobbies.com/4ch-rc-ep-2...ilplane-2.html

I am afraid though that the specified SKU for the plane is not found in the R2 manuals site. Thus, you will need to contact the vendor and ask them for a manual or ask them if any of the current manuals can be used to build your plane. You can also look at the available manuals and find a plane that is close to yours.

Here is the page with their motors.
http://www.r2hobbies.com/catalogsear...=D2836&x=7&y=7

Now, if you did get the Raptor, you will see on the R2 site, they specify the motor as a 1000kv motor with a 40 amp ESC. Judging from the nose of the plane and from the motors listed, you will need a 28mm diameter, 1000kv motor. The motors show with that stock number seem to pull around 23 amps continuous. If that is the case, then your 30 amp ESC is sufficent.

Looks like you will need 6 servos as well. Not sure of the rating for those but with 6 servos, a motor, receiver it is a very good bet the BEC on your ESC will go toes up and you will loose the plane. That means you should strongly consider a separate BEC to power the receiver and servos.

Hope this helps.

Does a V tail offer any advantage over other tail types?

http://www.djaerotech.com/dj_askjd/askdesign.html and scroll down to
'The Famous V-Tail Debate'

and this: http://www.southernsoaringclub.org.z...-Trimming.html

V-tails do take a little more understanding of them to set them up properly. They do not behave the save as the standard x-tail or cruciform tail.


It don't hurt that they are purtier than an X-tail either.

They do have to be set up properly, in particular both sides have to move identically when you give them a pitch control input.

They DO behave essentially the same as a conventional tail IF they are designed right. Unfortunately there are a bunch of them out there that are not designed right (they typically used the common but very wrong "projected area method"), and those have given the entire group a bad name. A badly designed tail is not going to perform or behave well, regardless of what category it fits in.

3mm shaft, 11x7 folder, 6mm shoulders. Be careful, my prop shredded itself on 200 Watts. I highly suggest a different prop and spinner if you go for a powerful setup.
