No you read me wrong, I was just ranting a little, but not at you.

I knew you were just looking for a few idea's. Send the BP10 back. Its all good.

Like I said Castle is good about fixing or replacing stuff, easier than any manufacture I know. And quick too.

I knew where you were coming from. Just had to git rid of a war story or two.

How about the guy with a vibrating motor thats flying one of my planes now. I also have a spare as we sent him a second that he didn't like either. Or another guy who sent in a motor that wouldn't turn anymore cause it was packed with sand and dirt.

Thats the stuff that keeps us from the real problems like your ESC.

Dude we are good.

I think that anyone who has ever worked retail or customer service can relate to what Tog is saying, I know I sure can. Tog has heard some of my stories so I will not repeat them here, let it suffice to say that I no longer do RTF micro models except under special circumstances, burned one too many times.

I think I mentioned it before but BP now has some really great digital micro servos from Blue Bird that are outstanding. I have had several people who have commented on how smooth my model flies with them, they center very well.

Tog and Ewo, I look forward to when you get your Illusions flying.........you are going to love them! By the way, the elevator mounted brakes work very nicely and don't give the waggle to the back end like the rudder brake does.

First let me start by saying thanks for all this info. I started by seeing the great value of a kit on bp hobbies, bought it, and then found this thread. I've been flying it for about a week, and it flys great!

I do have one request though, ewo, could you add the text below to the first post? it would help someone like me (just finding this thread) get to some info (I printed the soma 2 times now, and just got where the soma IV is, so now I'm off to print again...), also would be a good reference to find things in this massive thread... I spent some time going through all the attachments, and pulled out all the plans.


First post edited to add some links to help find plans in this post:
Amos kit from BP hobbies:

Amos tiled:

Amos 4A
Amos 80%

Soma bipe:

Soma II bipe:

Soma III bipe:

Soma IV


Misfit 40



landing gear plans:


amos with no side stiffeners, just CF rod (also flames)

yzguy , Wow ! You went through this thread and found all that??


I can not edit the first post in this thread.
doing so would reset the counter for the downloads for the plans back to zero and i don't want that to happen...................

You did do a lot of work here though and it is greatly appreciated
I will edit my second post though with the information you supplied
Thanks for the salvage work. everything does kinda run together here.
But its all fun

Well I'm in the glueing stage. Had a whole lot of things to do the past two days. The biggest making sure the car was in order, been putting a few miles on it lately. I have the fuse in the jig right now. Two NHP boxes pushed together against the fuse bottom holding the wing and the fuse square. Sometimes the simplest things work the best. I have a couple more for the tail section. One of these days I'll make a real jig but this works better than anything I've ever used. I just throw a few things in each box to keep them from moving around and off I go. Hope to have mine done tomorrow night. Now if the weather ever breaks. But I see ours is way better than what you mid states guys are getting.

I'm scaling down the bipe to 75% (and making it out of 3mm) for easier transport, and see how it does with a couple of small cheap motors I got to try out...

I saw the illustion and the air brakes (I'm assuming that is the stripps added to the alerons), but not sure what exactly is the point? I mean, I get the brakes, when you let off it slows down, but not sure why you want that. Also, why the holes?

Right now I'm still playing with the Amos kit, and trying to get it to hover.

The idea behind the brakes is to acheive a more constant speed. This can make loops etc look much nicer than having the model fly the first part of the loop slowly and then speed up on the downline portion of the loop. Same thing with stall turns etc. It is more important when flying indoors where you have little room and need to keep the speed down.

Actually brakes are nice outside also. Keeping the speed of the plane more constant is prime for better maneuvers. Plus it gives you a tick more time to think and react. Blasting around does not make learning easy nor does it make for nice looking maneuvers. My outdoor 6mm BP foam kit Amos has them as well as my 3mm depron indoor Amos.

Next the holes. On the tail they provide additional drag to slow the plane. The flat plates are omitted to help the planes tracking in the vertical. The holes in the ailerons infront of the brakes help air flow thru the front of the brake so you don't get a pocket of dead air. You always want the air to keep moving. The holes also redirect the air flow in a manner that actually helps the roll rate of the plane while producing drag.

The slot toward the leading edge near the tips help reduce the stall speed and the slats on each side help to stiffen but more to direct air. See no matter what the wing is, flat or foiled, the air will slip off the tips at high angles of atitude and when on it side. These sent the air in a positive direction instead of siding off in a non useful one.

so pretty much everything is for slow speed manuvering.... I'm having fun with this one the way it is so far, but keeping this other stuff in mind for the future.

I thought I'd share my pics. This is my first attempt at painting a foamy, and my first attempt with flames.

In the air the light colors did not show up all that well against the light sky, adding the mist of black in front of the flames really makes them show up.
