Default CERMARK F-18 HORNET, BUILT IT BETTER, STRONGER, AND FASTER!

Well, here we go again! My wife got me the F-16 2 years ago for my birthday... this year she got me the Hornet! She is a good wife!

Anyway, I figured we needed a good thread for the building of the plane so we can figure out what works and what does not.

The last F-16 post was pretty sucessful..... so here we go again!



This is Cermarks second installment in the modern prop-jet market.

It is a high quality kit, no doubt a winner....

LIKES:

1. The latch canopy and rear hatch beat the heck out of the screw on fiasco of the version 2 F-16. The latch mechanisms are real nice!

2. Looks like a nice set of retracts!

3. Beautiful Finish... nice graphics!

4. Good support from Cermark... they usually fix any problems!

DISLIKES:

1. Initially I noticed what Bob had seen.... not a lot of space in the nose for a larger fuel tank.

2. The only problem so far is the USED nose strut, wheel and mechanism I recieved (not sure how that happened) and missing spinner.... Cermark sent me the spinner and I am waiting on the nose gear!

3. Cheap CA hinges.

4. NOTE TO CERMARK: YOU MUST OVERLAP THE ULTRACOTE A LITTLE (ABOUT 1/4", PREFERABLY ON THE UNDERSIDE) ON THE LEADING EDGE INSTEAD OF STOPPING AT THE VERY TIP OF THE LEADING EDGE ON ALL CONTROL SURFACES..... SO THE COVERING DOES NOT COME OFF IN FLIGHT. I HAVE SEEN THEM COME OFF ON THE F-16!

GENERAL:

If there is anyone out there who is good with graphics.... We need a good BLUE ANGELS logo for the nose!



THATS ALL FOR NOW!

RICH

Got mine the week before.
Arrived in A1 shape. Same good points as Rich's.

Some bad:
1) Use better CA hinges.
2) Carefully examine all formers and glue joints. I will be going over some of mine with a tube of Aeropoxy.
3) Reinforce and soak the retract plates. They are doubled up 1/8" plates, and are not solid, so hit 'em with a lot of thin ca.
4) Check your wing tube. Mine looks horribly one sided, based upon the locating screw holes.

Need BA graphic for the nose!

Rich - forgot to mention - great title for the thread! .... sounds familiar

I borrowed Steve Shumate's decals for his foamy pusher prop, from the RC Groups thread. These should do quite nicely!

I am trying to make this a tradition!

I have had mine around 6 weeks now.... just waiting on Cermark for the spinner and nose gear!

I am not real excited about the lack of wood around the outer stabilizer bearing... may need to come up with something to reinforce it!

Otherwise a sweet plane!

Sparhawk..... what method do you use to turn that logo into a useable sticker or decal?

Default RE: CERMARK F-18 HORNET, BUILT IT BETTER, STRONGER, AND FASTER!

Easy and will work great:

Method 1

1 - Testors Decal paper - White!
2 - Image needs to be scaled to correct size (Photoshop)
3 - Print the image on the decal paper - follow paper directions w.r.t. to ink settings
4 - let image dry thoroughly. 15 - 30 mins.
5 - lightly spray with a Krylon Clearcoat spray... let dry
6 - spray a second clearcoat... let dry!
7 - xacto knife around the decal, careful to not have any white edges.
8 - waterslide onto airframe.... carefully blot dry and let dry overnight.
9 - mask out and clearcoat the decal to seal it on the airframe with a 1/8 - 1/4" area around the decal.

Tip - If you leave a slight blue edge around the decal when printing, then it will blend to the fuse paint a lot easier. You will barely notice the slight variation between the two blues.


Method 2

Same as above, but use clear decal paper. You must rely on applying a separate white basecoat, sized the same as your intended decal, to the airframe. (paint, Monokote Trim sheet, etc)
Slide the decal made on the clear decal paper over your white basecoat.
Apply a final clearcoat to seal to airframe.

An example of this method was done on my HET F18.

Well folks…. Heres something you don’t see every day! Slightly off topic.... But you will probably want to beef up the underside of the F-18 engine mounts after you see this.

One entire prop blade separated INFLIGHT on a high speed pass! The entire engine separated from the mount, the carburetor separated from the engine, and the prop and spinner were totally destroyed! Fortunately they all hung on (by the fuel lines only) for the ride home. Luckily I had enough energy stored up to pitch up into a modified downwind/Split-S for a safe landing.

Been running this engine for years with a 12-6 APC never seen anything like it.

Although the prop failure was the cause…. I would suggest that Cermark use better wood or better yet… carbon fiber for the mount. The wood is so cheap ALL THE BLIND NUTS WERE PULLED OUT OF THE WOOD! I noticed on the Hornet they did put some hard wood on the topside of the mount.

Check out the pics…..

I guess I got some repairs to make….

Another notworthy item.... the screws and blind nuts included with the F-18 and F-16 do not fit the JETT.

If you are in the Bahamas... that is probably why the shipping is more expensive!

Graves R/C in Orlando,FL may have them in stock. May be cheaper from there?

The post that Blade47 posted is mine, and ya this plane flys absolutely fantastic. much better than the F-16:
- much shorter take off roll
- flys truer and more precise
- more aerobatic
- seems to go faster
- the front twin wheel strut we used causes the plane to be EXTREMELY stable against tipping on the ground

The OS 91 \ Jett LX muffler \ 12x8 combo is absolutely amazing to say the least ! it can climb vertically from takeoff after only 60 feet of runway with no sweat !

Did i mention i like this plane ?

PS - kingthight, i think a14" would not work, you would probably be extremely close to the ground with that !

i was getting around 13K (i think 12.6-12.8) but the engine was still a tad rich, and even at that setting it was flying amazing.

next time out we will lean it out and check again.

Anyone else with the F-18 have a CG problem like dotdigital on the other thread. I would hate to lose it on the first flight. Was his problem just an anomoly? 7" back per manual is correct? Thanks.
