Redesign/build FEJ
Starting a thread for redesigning and rebuilding FEJ F-14 1/7 F-18 1/7 F-16 1/7. This is for everyone who has FEJ models and wants to have them in the air flying safe and fun. Let's keep it to constructive constructing posts only :)

RE: Redesign/build FEJ
Great idea.
|
RE: Redesign/build FEJ
Add F-16 1/6th scale to the list.

stabs. The old F-18F ( no HC) has been flown with no problems and has solid plywood bulkheads for the bolts so its MAC location should be ok. Does anyone have that calculation?

Great idea... I wish I had a plane I could participate with

I feel you on that one :(

On theF-18F main gear I am adding strength by turning it into an I beam .

RE: Redesign/build FEJ
wao i like that idea lets do it guys

What is wrong with the 1/6 f-16?

Cannot move the linkages in toward the servo anymore because of clearances with the pipes so I can make an arm extension here.

RE: Redesign/build FEJ
The F15 1/7.. known issues? Left out?
|
RE: Redesign/build FEJ
Jim is your f-18 the 1/6 or the 1/7?
|
RE: Redesign/build FEJ
F-18 is 1/7th
|
RE: Redesign/build FEJ
Since this has been brought to attention, I have a 1/8th F-16 I am trying to get finished up. Does anyone have a C.G. location or any mods that it may need ?
As far as I can tell, only the gear are having issues due to undersized air rams. Tim |
RE: Redesign/build FEJ
Thanks, are you going to have anything for my jets?

I Have the 1/7th F-16 HC. Should I do something to strengthen the stab itself?

Jim,
This is from Oli's excellent article published in the April/May issue of RCJI. It WORKS! David S |
RE: Redesign/build FEJ
Doom I had to 1/6 version, had honeycomb stabs and rudder. I never had flutter with either I did full speed flight with it as well. The only mod I did to my f16 was convert my gear to electric and add small block to door cylinder which was on honeycomb. I had the old style pull pull with ply bulkheads.

RE: Redesign/build FEJ
Thats good to know. I still might back fill with Hysol. or build my own set of stabs.

RE: Redesign/build FEJ
To try and be constructive here, not all FEJ planes are created equal. The older fiberglass planes might have more success. The tried and true planes that are also made by other manufacturers may also have more success. The 1/6 F-16 and 1/4 Hawk come to mind. Guys seem to have success with them... at least the fiberglass versions.
It's the new planes designed by FEJ that seem problematic (F-14, large F-18) and if you guys can figure out a solution to make them airworthy then maybe FEJ will incorporate that feedback. |

RE: Redesign/build FEJ
Just a thought here , but has anyone tried to drill a small hole into the stabs and fill with a measurement of urethane expanding foam ? It would NOT add a lot of weight and add torsion strength to the stabs.

RE: Redesign/build FEJ
Tam,
You dont think injection when still in molds would work either? I had spine surgery this morning and on some of the GOOD stuff right now. I am just rambling, usually I do not post. I just read everyones topics and replies to learn from. Glad to see ya back in the Hobby regularly. Maybe we need make good kits for everyone :,) Tim |

I try to chime in here and there to share some my experience. I do more fishing lately. Flying once awhile with groups guy at BW. |
RE: Redesign/build FEJ
Agree with Tam on that. The typical expanding foam actually generates a fair bit of pressure and will bulge out the skins.(I tried to make a plug once with this stuff and it wrecked everything) But a good idea though if we could find some that is a bit on the lighter side.

RE: Redesign/build FEJ
Yep, 3 articles of 3 pages with full build and upgrade details, all the pictures and test flights including Tam's pipe upgrade.
This jet now is 3 years old and has nearly 300 flights on the clock. It does very well with the B300F on board. You guys also have a full detail of these mods in the F-18F thread: http://www.rcuniverse.com/forum/m_77..._1/key_/tm.htm I have also detailed the full theoretical analysis of the stabilator on this plane in the flight controls article series. I will publish a resume of this in the stabilizer blog part 2. |

RE: Redesign/build FEJ
Just wondering why you would use a straight servo arm with the off-set on one side only to put the one pushrod at 90deg to the centre of the servo output. I've always used a servo disc and off-set both balls to the rear meaning both rods are at 90deg to the output spline at neutral and are of equall lenth.</p> I know there will be good reason for the straight arm against the symmetrical set-up the round disc allows ?</p> Thanks in advance</p> john</p> |
