RE: Nitro Models Formost 150 are in the USA
 

Wow I just got home to see this.
I didn’t say it was a build thread I was just pointing out that there was another thread for opinions, as a matter of fact you posted the same thing on SpiderJets opinion thread and I didn’t see the need for double posting.

Not trying to get personal and I am truly sorry if I struck a nerve.

All of us reading this form are aware of the short comings and we can take measures to rectify, so why continue to preach to the choir because those who could use your insightfulness are not reading this form.

You have raised the point that this is a questionable model in your opinion.

What is the ultimate solution to protect all of humanity? (Rhetorical question only);)

I assume that you have personally inspected this model to be so firm in your resolve.

Maybe the solution is to setup a review panel of expert aeronautical engineers to judge the safety of all imported models.:eek:

Maybe the model industry could adopt a voluntary system like the EU’s CE mark scheme, the manufacture would be required to sign a declaration of conformity stating that the design meets all of the requirements and if it is found not to comply then legal consequences would ensue.

Maybe a set of standards could be developed for all manufacture to follow, and then the Agency for Model Safety (something like UL) could review the design and approve it.

Maybe I just invented a new business model (AFMS)…. any investors out there?

In case you haven’t guessed… I am a product conformance engineer when not playing with models.

SpiderJets and ThudDriver response said it eloquently so I guess there is nothing else to add except I think this horse has been beaten to death, oh no I guess I should re-phrase that…. sorry I couldn’t resist.[X(] :)
:):):)RELAX already, it's a freakin' hobby !! :-)

RE: Nitro Models Formost 150 are in the USA
 

Looking for engine suggestions. Ideally, I'm looking for information that would probably bore the experienced folks, but would be very helpful for a jet novice such as myself.

What thrust and weight are best for the Formost 150? How much would be too little or too much for both thrust and weight? Would it be possible to use an air start turbine, or is a full auto start the best recommendation?

I've been looking at the Jetcat line, either a P70 or P80. Also looking at JetJoe JJ1800 (yes I've read the Jet Joe bashing threads). Saw two Ram 750s for sale here for what looks like a great price. Maybe even the JetCentral Falcon. Just trying to get the best bang for the buck, and incur as few headaches as possible for someone with my novice status.

Thanks,

-Jorden

RE: Nitro Models Formost 150 are in the USA
 

Well I a have a Ram 500 I am planning on putting in this, I had it in my Baby Boomerang and it flew great. I also have a Falcon, it is an awesome engine and I had that in my Boomerang its now in my JL T-45.

So what I am saying anything is possible; however please do your homework on this airframe to make sure it is airworthy.

RE: Nitro Models Formost 150 are in the USA
 

Thanks for the info. I'm following the two threads here closely, as well as the others I can find. I know my limits, operate well within them, and am not afraid to ask questions, even the stupid ones. Hopefully folks aren't afraid to answr them! :D

RE: Nitro Models Formost 150 are in the USA
 

Any of the smaller engines, Wren, P-60, Bee, Falcon, P-70 would be great. Mines getting my older P-80 because it fits and my P-70 is busy in the Velox.

Jorden
I don't think you have to worry about that ;)

RE: Nitro Models Formost 150 are in the USA
 

Well it looks like my package arrived according to the UPS site, can't wait to get home and open up the box

RE: Nitro Models Formost 150 are in the USA
 

I think you should leave work early today so you can post your findings.
Hope all is in good shape.
jef

RE: Nitro Models Formost 150 are in the USA
 

yes lets see the changes
personaly i dont think there are any
exept that they did not glue in the formers covering the front retract.
curious how they mount the front retract.
also apply some force on a bearer and see if the glue just snaps
ours did..

RE: Nitro Models Formost 150 are in the USA
 

I will leave work one hour early as long as no one tells my boss:D

RE: Nitro Models Formost 150 are in the USA
 

Received the kit (notice I didn't say ARF);)
The packaging was good except the instruction manual and the decals were stuck to the lid of the box.

I'm afraid the changes that Nitro Models touted are not worth much, the front bulkheads are made from two 3mm Chinese Ply wood.
Know as Cheep Raggedy Ass Plywood also know as (CRAP).

Sandor,
You are able to break the bulkheads out with little force you have mentioned in your thread.

I have a bunch of photos however I will have to post tomorrow as I am out of time.
The overall quality is very good except for the CRAP so for the money it is an excellent buy and will make a great building project.

The fiberglass work and paint is as good as any other manufacturer coming out of China.

Thats all for now

Nitro Models Formost 150 Build and Turbine Mod review

Horizontal Stab 192 Grams (Built Up Construction, Ribs, fully sheeted, Iron on covering, I would install the elevator servo in the center, the stab is a flat bottom airfoil and is on the thin side .75” (19mm), a servo blister would be required for an appropriately sized servo for the task.

Wing Panel 262 Grams each (Built Up Construction, Ribs, fully sheeted, Iron on covering (great quality)
Main Spar Receptacle – Fiberglass Tube, .637 ID (16mm) Insertion depth 6.12” (155mm)
Anti Rotation Receptacle - Fiberglass Tube, .405 ID (10mm) Insertion depth 2.87” (73mm)
Main Spar Tube – Unknown grade of Aluminum Length 12.56” (320mm), OD .630 (16mm), wall thickness .04 (1mm)
Anti Rotation Tube – Unknown grade of Aluminum Length 6.81” (173mm), OD .395 (10mm), wall thickness .04” (1mm)
This will need a continuous main spar tube, see notes under fuselage below.

There are no flaps, however it would be quite simple to split the ailerons into two sections to create flaps, the outer section could be made into a 10” (254mm) length leaving approximately 12.75 (324mm) inch for the flap section. The width of the section is 2.25” (57mm)
The provided holes for the ailerons servos would now become the flap servo locations and two new holes could be cut in for the aileron servos. The ribs have cutout which will allow the servo leads to be routed to the new locations.

The wings are held on with two long Allan head cap screws, there are access hatches on the bottom of the wing panels in which the bolts are inserted, they are routed through the booms and mate with a blind nut located in the center section of the fuselage. Access panel covers are supplied and fit quite well.

Rudder 10grams ea. (Built Up Construction, Ribs, fully sheeted, Iron on covering

Booms – 390 Grams ea. Fiberglass construction, Front of boom has plywood reinforcement on each side from the LE back approximately 14” (355mm), thickness at this section .12” (3mm). Boom seams have been taken out; paint looks good, vinyl graphics with overall clear coat. The vertical fins do flex as there is no internal structure to them, I believe the easiest method to strengthen has been explained by SpiderJets in his form; i.e. use the two part expandable foam.

Front Hatch 190 Grams fiberglass construction, painted with clear coat, glass thickness .03” (.7mm)

Canopy 60 Grams, I don’t like the shape.

Fuselage Fiberglass construction, don’t have the weight as it was beyond my scales capacity.
All seems have been filled and finished, paint work is great, overall clear coat, no decals have been applied (thank goodness).
Plywood formers will most likely work as is with the exception of the landing gear areas.

This aircraft requires a continuous spar, with the design as supplied you can flex the entire structure; this is not safe for turbine operation.

As received the wing spar tubes will insert into the center section for 6.3” (160mm) where a stop is placed. The plywood stop is glued in with the special removable glue, one tap with a mallet on the spar tube inserted into the center section and the ply plate falls out.
The next interference is with the molded in wheel well, this will have to be cut to allow clearance for a continuous CF spar tube, the tube will need to be .63” (.625 seems to be the standard in the US, so a clear coat would need to be applied to make up the difference) (16mm) OD x at least 36” (915mm) Long

All formers associated with LG should be removed and made from aircraft grade plywood and or hard wood or reinforced with CF. The glue joints are made with some sort of brittle glue (CA???) and formers can be removed with a sharp blow to them.
Fuels Tank area is 7” (178mm) LG x 4.37 (111mm) Deep x 5.5” (140mm) wide
If you want a different configuration remove bulkheads and make your own. Regardless of what is used, you should re glue all joint with the appropriate epoxy.

The nose wheel well opening has not been cut out so you are free to configure this area as you see fit. The cutout lines are present however you could choose to create a different shape. I plan on making new bulkheads and installing the servo directly on the strut eliminating cables and other sliding linkages set-ups.

RCISFUN,
Thanks for the report and photos. I look forward to seeing the Formost at Florida Jets.

RE: Nitro Models Formost 150 are in the USA
 

Ditto!

Mr. UPS man should be delivering mine tomorrow!

RE: Nitro Models Formost 150 are in the USA
 

Quick question concerning CF tube, can Pultrated tube be used in this application?

I found some that has .105" thick wall with an O.D. of .625 x 48" Long.

Thanks

Just received a set of Robart 730 retracts today, they fit perfect

RE: Nitro Models Formost 150 are in the USA
 

Well, received my Formost 150 today. With the exception of a trashed canopy, all looks good. I haven't looked through the instructions yet, but I'm remiss to see how this thing is being marketed for piston engines. It definitely comes with the cradles for a turbine, or even a ducted fan. Nonetheless, it looks like a very nicely made plane. Someone must have been listening about the glue, because mine has the bulkheads/formers very well glued into place. Interestingly enough, the glue looks for all the world like glue from a hot glue gun. The former next to the one that holds the nose gear is doubled along the bottom half. All in all, even with the work that will be needed, I still think it was a good buy. Heck, I may even get a second one and make it a gasser for practice. Better yet, make this one a gasser and convert it once the fixes have all been worked out. Oh and yup, the tail booms do need to be strengthened for turbine flight. I wonder if the should be done for gasser flight too. It's going to be quite a while before I'm able to get this thing into the air as a turbine any way.

-Jorden

Edit: Actually, the canopy is very thin along the edges. I don't see how it's going to stand up to any real usage. Probably a good idea to look for a better one somewhere, or make one. I just sent Nitro Planes a request for a replacement. We'll see how that goes.

hello,
Can you say yourself what is the profiles of the wings
it is an naca 2412???
thanks
Michel

RE: Nitro Models Formost 150 are in the USA
 

Has anyone installed a turbine in there Formost yet? If so what did it take? I see there is a beef up kit from Digitech, and was wondering if it's needed for the version 2 150? Just wondering what it's going to take. Thanks in advance! Sam... (818) 822-5914
