now that is a classic one:D:D

up to now this factory has had 6 different people andswering emails or plans..
good luck ..

RCISFUN;

Factory formers and tray that almost fell out... Do you think factory did not clean off mold release or just bad glue. Should I re-apply
EPOXY over factory glue?

RE: What do you think of FORMOST 150 ?
 

Robert, I have been using medium grit (80) sand paper to prep all of the fiberglass to plywood joints then using 15 min epoxy mixed with micro balloons.
Good luck with your build

Well with the price of gas what it is today I have decided that I need to take advantage of a small airport that is about 4 miles from my house, my normal jet airport is 50 miles one way. The problem with the close airport is the runway is very rough, to that end I have decided to purchase the BEST struts available so I have ordered a set of Jet-1A struts from Sandor and I would like to thank Sandor for his suggestions.

The struts will be paid for if I eliminate 12 trips to my normal field :D

RE: What do you think of FORMOST 150 ?
 

Struts go out today to Hamburg...

RE: What do you think of FORMOST 150 ?
 

Sandor, THANKS!!!!
Can't wait to pick them up next week;)

Spiderjets
You mentioned 3 degrees down thrust on the engine. Do think that is still recommended ?

Randy,

I have not been able to do further testing, in particular checking the CG and/or incidence of the turbine.
I will keep you posted when I will resume further testing.

Bad glue. It is too brittle but hard to remove from the fiberglass anyway.

RE: What do you think of FORMOST 150 ?
 

Nicolas, anything new to report?

RE: What do you think of FORMOST 150 ?
 

yes he bought a almost brand new Cutting table to make wings
and the software that comes with it;).
it was sitting in my shop for years ,and i cut exactly one wing with it as a demo.
after that i went ARF instead :D.
i think he is making something else soon

RE: What do you think of FORMOST 150 ?
 

Thanks Sandor for the update, I haven't had much time lately and I won't for the next few weeks:(
I do plan on getting this thing flying by the end of April:)

I made a 1/4" (6mm) plywood servo mount for the rudder servos which seems to work well.

RE: What do you think of FORMOST 150 ?
 

Wow, this is impressive ! I think I have my own fanclub now ! ;)

I have closed the balsa wings again last night aftter the mods were completed, and the wood glue is now drying on the central heating (the longer, the lighter !).
Glassing is for tomorrow.

Things are going slow now, the weather is bad anyway... [:o]

Sandor,

Is my Jet-1A nose retract unit for the Fomost under its' way ?

Nicolas.

RE: What do you think of FORMOST 150 ?
 

Nicolas I'm glad to see your making progress; hope you can fly again soon providing the weather corporates:)

Sandor,
I just received word that my struts arrived at my plant....THANK YOU;)

RE: What do you think of FORMOST 150 ?
 

uuuhhhmmmmm no?:eek:
exuse me , will do tommorow
sorry about the screw up , been busy[:@]

RE: What do you think of FORMOST 150 ?
 

your Welcome

RE: What do you think of FORMOST 150 ?
 

Yes, please do send it, as I will be back to Belgium next week and need to fly the Formost with Nico.:D:D

Chris

RE: What do you think of FORMOST 150 ?
 

you have a big cargo area?
i will shove a lot of them in that plane

RE: What do you think of FORMOST 150 ?
 

I hope to be able to come and see you Tuesday, April 15th very early in the morning!!!!

Negative dihedral on the Formost ?!?
---------------------------------------------

Gents, is there anyone who can check the dihedral on their plane ?

I discovered yesterday that my Fomost has serious negative "V" on the right wing. I swapped my two sets of wings and both right wings were identical. It is less pronounced on the left wing, but still there.
When studying in detail the construction/designing, I think the mistake occurred at the designing stage : the wing tubes are designed for simplicity in the vertical MIDDLE of each of the three mid wing ribs ; and because the wing is tapered and the airfoil of a type like NACA 2412 (semi-symmetrical) with less % thickness at the wing tip, the result is that the bottom side of the wing is almost flat and the "V" is at the top side.
Must say, I have never seen anything like this before on a model. My first flights were most likely with such dihedral as well, and no bad tendency noted,.... but still... ??? [&:]

Can someone check his ?
Put a single alu tube (from the kit) in both wings and place it on a table and look where the "V" is ?

Seriously disappointing how little care and insight was used by the factory when the wing (... and the rest...) was designed.
Anyone can create better in less than half an hour from scratch with a software tool like WingDesigner...

RE: What do you think of FORMOST 150 ?
 

More and more I am convinced that, if Fly-Models wants to make a success with such plane, they must do their complete homework much much better, from proper designing to careful manufacturing, and better start all over again and only keep the tailbooms + fuselage as a base like they are now (=the fiberglass parts).

RE: What do you think of FORMOST 150 ?
 

Jeezzzz, my previous eagerness of completing this model, even with its existing drawbacks has now dripped away to below mean sea level...must see if I can reject my order with the dealer. What more we will find in this chinese dragon?
Greets from HKG....

RE: What do you think of FORMOST 150 ?
 

FWIW, such a "negative dihedral" as called anhedral....it's gotta be demoralizing to keep on finding one problem after another!

RE: What do you think of FORMOST 150 ?
 

Nicolas, there is something strange here.

I placed a straight edge on the bottom of my wing and I inserted the alum tube into the wing and measured from the bottom edge of the wing to the edge of the tube.

The Right wing had a distance of 7/8" (22mm) and the Left wing had a measurement of 3/4" (19 mm).

The measurements were taken at the same point on both wings.

You can see from the photos that the taper (distance from tube to the bottom surface of wing) is increasing from the wing tip to the root of the wing which indicates a positive dihedral.
