Title: The Big Foam warbirds from FMS.
Post by: flyingboxcar on January 30, 2011, 10:33:21 PM
This was picked up while on a business trip to Manila. The model comes almost ready in real sense, that you just need to add your Rx and Bty paks, there is a version where even the Bty packs are installed.
All servos (5 of them), motor, ESC, UBEC, prop, electric  retracts are supplied and fitted, you just slap this thing together. In fact you could take the whole box to the flying field from the shop, assemble it there and fly.
Here are some pictures, of the supplied box and box contents

The first attempt, to fly this model, was made a couple of months back. Battery used was two 2000 MaH, 7.4 V packs in parallel, with the stock electronics supplied.
A Futaba 6 Ch FM Receiver was put in, servos hooked and the model took off in blue yonder in the hands of selected test pilot. Couple of circuits up and the dance of death started. The controls were badly glitching due to heavy radio interference. The flight ended uncerimoniously resulting in a bent motor shaft and busted wing. Post crash investigation revealed that with the Tx antena collapsed range was down to 4-5 feet. On this day, despite my religious following of the good practice, I had missed on conducting a range test. Oh well!!! You live and learn. Anyway the damage was not that bad, but it certainly did dent more than some foam!! :-)  

Later a spare motor shaft and spare props (fearing more would be required) were ordered from RC castle which arrived in no time. But something or other in the way kept me from working on the busted wing.

Finally, took the broken wing down this week, gave it a good lookover to decide on course of action for intended repairs. A trip to LHS to get some different dia carbon rods, and all was set.

The broken wing was repaired by cutting a span wise grooves of suitable length, inserting a carbon rod for the full length of the cut groove and everything secured with copious amount of epoxy.  As soon as the epoxy had cured, I was ready and back in business.

This time the Rx selected was a Futaba 6 Ch PCM one, a thorough range check showed no adverse affect, so the two packs were put on charge while I flew the IC powere ones.  

Happy to say that the maiden went off well and though a flight was put in it would still needs some tweaks especially in the CG department for it to be a nice flyer.

Here are some pictures for you people, Pradeep did a credible job with his camera

Seriously, I had not seen that, till now :thumbsup:.
Looks like thats a remenant from the artwork for the box FMS does for thier DF foamies  ;D
The only place they could put that in is the mid fuse it is big enough to accomodate that :giggle:

Tar Heel (or Tarheel) is a nickname applied to the state and inhabitants of
North Carolina. There is a town in Bladen County, North Carolina, named Tar Heel. here is the link:

http://en.wikipedia.org/wiki/Tar_Heel

So I guess, Tarheel hal refers to a person Hal who was from North Carolina.


Awesome model and really beautiful shots. May I request you for some bigger pictures at my email id? I'll be grateful.

VC I did send you the pictures today morning, did you get those?

Since the bird looked too spick and span, thought it would be good to weather it down a bit.
How do we do it?
First try was with paint and brush, but no good, after some trial and erro hit upon the idea of using powder scraped off from pencil leads. So sons bag was raided for some used and discarded pencils from lead was scraped off to give a powder, this along with some crayons, were used to dirty up the wings.
Now I have to start the fuse and tail group
Here are some pictures  
1. The right wing with just a bit of touch up
2. Same wing after completion
3. Right wing underside, gun barells  still to be painted black
4. The left wing, with all the mistakes of first attempt with paint showing up

5. Left wing underneath
And you can even make out the two locations where grooves were cut and carbon rods buried in to repair the broken wing

Post by: flyingboxcar on February 02, 2011, 09:51:57 PM
I guess the dirtying has been a bit overdone, what do you guys think?


Title: Re: The Big Foam warbirds from FMS.
Post by: flyingboxcar on February 06, 2011, 10:40:54 PM
A few more pictures from todays outing. Better pictures are awaited, but these would sure give you an idea on the completed weathering/dirtying


Title: Re: The Big Foam warbirds from FMS.

Actually some one at the field commented that I needed to put in some bullet holes!!!!

Let them take a shot at it!

Looking real good Captain.

Thanks Susheel.
Sure will ask them guys to get thier Japnese/German/Italian automatics along if they want to take a shot at the Yankee warbird!

Here are couple more aerial and ground shots of the model after it was given the well used/war weary look.
Again  the man weilding the camera was same, Pradeep. Thanks to him I am able to share this pics with all

1. On starting to taxi it was realized that the rudder was reversed (this happened due to some work I did the previous day to modify the pushrod routing)
2. So it was back to quick set up at the field
3. Finally up and away

May be next time I take this model out, I would request Pradeep to take a video

Guys would appreciate some feedback on the before and after pictures (i.e. after the model has been diritied a bit), Do you think it looks the part as in war weary/well worked aircraft or does the weathering look artificial?


Title: Re: The Big Foam warbirds from FMS.
Post by: sushil_anand on February 23, 2011, 01:16:42 PM
"Weather" it looks real or not, is pure perception. I think it's fine. BTW how is it as a flier?


Title: Re: The Big Foam warbirds from FMS.
Post by: anwar on February 23, 2011, 01:32:13 PM
One thing I learnt from Mike was how important weathering is in scale modeling. He was explaining how he did it on his latest model.  It does add a great sense of realism and a rustic feeling (for lack of a better word) to the model.

@ Susheel,
Nice flyer, Havent done any aerobatics yet as the wing fixing method does not inspire any confidence.
Both the wings slide on a carbon tube and are  plugged  into fuse cavity. I shudder to think what if... I pull a loop or roll ?
Thinking of modifying by making the wings attach permanently or by using velcro strips. Not yet decided

My own perception about the weathering which I did is that, it's too symmetrical to look authentic


Title: Re: The Big Foam warbirds from FMS.
Post by: sushil_anand on February 23, 2011, 03:40:19 PM
How are they "plugged"? This would be the only area of concern, I would think, as the rest is pretty normal. Also, planes like these are very lightly loaded, in all manners of speaking.


Title: Re: The Big Foam warbirds from FMS.
Post by: flyingboxcar on February 23, 2011, 04:04:23 PM
Plugged as in just pushed in no means of fixing so that the wing halves do not slide out. Especially given the nature of foam to compress I am afraid that the after some time the friction fit would be lost. And I do not want that to happen mid air  


Title: Re: The Big Foam warbirds from FMS.
Post by: anwar on February 23, 2011, 04:55:50 PM
I have seen magnets help in this situation, if I understand this correctly.

Post by: flyingboxcar on February 23, 2011, 07:32:40 PM
Yes Anwar that should also work, think will try out velcro first (readily availble in my spares bin)
