with ailerons there is a couple different places usually in the wing though. there are a couple pictures buried in the thread about that which would be more helpfull than anything i know. for stock rudder and elevator the stock location(just past the wing in the fuse) worked fine for me and it still balances right. i used 5g servos also. and its the fw190. getting the p-47 next though. still havn't gotten a chance to fly it yet so take my advice at your own caution.

Thanks in the past, with other planes, I have put the servo in the middle of the wing more or less, then run a pushrod to the aileron cutout.

um hmm have you seen the pz um p-51? it uses torque rods for ailerons. i'm not good at explaining things. lots of common rtfs use them too cause they only use 1 servo.

My idea is based on :
XP7A ESC (4 gr wtih connectors and heatshrink)
Lipo 1 cell 400ma (12 gr)
4,6gr AEORC CO5 outrunner motor (KV 11000) with gearbox system 1:3,75
2,5 gr servos
personnal gearbox

Does someone has tried that, or a similar configuration??

Have a nice day

You'll need too watch the weight as it could easily be too heavy to fly well on 1S. You may want to consider the new "1.5g" servos from HK. It could save about 3g over the "2.5g" servos.

Hello,

Now I have finished my P47 with one cell lipo.
These days, I was able to finally test it flies really well, but some changes were necessary: anti insufficient torque angle, and angle drill too large. I am very happy with my gear home, but I still test designed to limit consumption and therefore increase endurance.
Attached two photos of the gear, other pictures in a few days.
My configuration:
Lipo one cell, 500m 13,8 gr
Receiver Walkera
ESC XP7A
Servo 2,5gr
AEO motor KV11500
Home build gear system, I had a fear about the gearbox, but it works very fine.
In a few days I will send other photos of the bird full.
Best regards

Robert,
Thanks for posting the vids. I've built a couple of these birds over the last few years and am always interested in the way people go about modifying them. I'm currently flying a P-40 but have a stable of kits in the shop waiting in line for their turn and I'm never too proud to steal someone else's mods in order to improve them!
Thanks again
Scott

Looking forward to your build(s). Share some pictures of your work in progress. It'll show us your techniques. Did you start on the mustang or the FW190 already?

The spitfire is still waiting on a paintjob but since I've been redecorating the house I did not find time yet. I did make a nice place to store my finished cox/gravity warbirds. When I get my camera back I'll show you a picture.

Have not started the next FW-190 or the Mustang. I still haven't flown the first FW!! WAY too many projects going right now. For the Mustang I was thinking of a B model (Shangri-La?) if I can figure out a light weight method of making the turtleback (vac formed, 1 mm depron, etc). Callies has some nice graphics for the parkzone micro mustangs---I figure she might be able to scale them up a little. Some GREAT how-to videos, BTW,

Hi Kurt,

Why don't you just cut away the top of the tailsection and replace that with a foam block to create the turtleback? You can reinforce the fuse with some foam ribs and sand the turtleback i shape. When finished, you can hollow the turtleback. I use some double sided tape to attach the foam to the fuse for sanding (bits and pieces here and there... you do want to be able to remove after sanding).

That's how I would do it.

You really need to take a break from your projects to fly the FW190. I do expect an in fligh picture to prove you really did fly the bird . It is after all the reason why we are in a hobby which defines itself with actual flying, radio controlled planes.

I think callies will be able to make some nice graphics. I did see some of the work they have delivered and that was awsome. For a B-version You could also do the old crow version. I have the Flying styro kit version of the old crow. It makes a nice model. You could look it up on the net to act as an example. It has the nice spitfire like round canopy.

I appreciate you like the how it works video's. They are pretty dated already. I might do some new ones in HD . I really like my toys!

Robert

I own the p51 and looked at it. I didn't know that was called a torque rod. Thanks.
