Default Patriot

Here's my new Patriot. It's got 8 flights on it so far. The first couple were disasters - plane badly out of trim and not balanced properly ( I thought I had it right). The engine also quit both times. I think I had a little radio interference too, as the plane did a couple of major wiggles without any stick movement. Luckily got it down without damage. Fixed the problems (and re-routed the antenna) and the last few flights have been great. Very fast!

Here's the particulars on the plane:

- Kit built (bought the kit through RCUniverse)
- Super Tiger 45 engine, MAC's tuned pipe, Master Airscrew 10-9 prop
- Hobbico Retracts (The mains actually work pretty well for a $29 system, but the nose gear sucks. If I had to do it again I'd put a top-of-line air system in).

Some of you guys may not like the really "fake" inlets I've put on the side (just grey and black Ultracote), but they look okay at 150 feet! Couldn't stand the drag of the ones that come with the kit, but I liked the look.

Why don't you put a decent APC prop on that thing and see what she'll REALLY do!

Gary:

I hear ya. What would you recommend? I've got an APC 10-8 and an 11-7 handy. I read on this site a while back about a guy who cut down an APC 11-12 to 9.75 diameter, so I was planning on trying that eventually. I've been so wrapped up working the bugs out of the plane I haven't had time to experiment.

My engine is taching only 13,800 rpms (using 15% fuel). I realize this is not the best engine for this plane, but these rpm's don't even come close to advertized (16,000). Any ideas?


Jim

P.S. Here's another pic that shows my cheezy decal style inlets a little better.......

BEAUTIFUL patriot!

Wow- that is ALOT of prop. I would try a 10x8 or 9x9--- With a tuned pipe it sounds like you are not gettin' "on the pipe" the 9x9 (APC btw-) should help...

Those air intakes just slow you down anyway and your fakes look really good-

Congrats on the maiden flights- keep us posted!

Great looking plane! Enjoy it.

Ditto....... to Razor's post....

Thats a LOT of prop for an ST45. 10x9 is some serious load. If you bought a pre-tuned system from MACS, it is tuned for 14.5k rpm or higher. Likely set about 12" for around 15-16K rpm. You want to prop it to get up there.

IF you are turning a 10x9 at 13.8K, thats not a bad engine!

Put a 9x7 or 10x6 APC on it, see if it gets up into the 15K RPM range. Let it unload.

Is the patriot a pretty easy build? Is there a similar design in an ARF form? I already have one build on the table, but would like to get a speed plane up

I would not consider the Patriot kit an easy build. It has a fair amount of carving, and the turtle deck is bent sheet stock, the aft portion of which is real tricky. The control system is different from most models, so takes time to complete. Air retracts will double your building time, and mechanicals will triple it.

There is a new large size ARF version of the plane available.

nice patriot jamesg33.
how long did it take you to build it ?

i've been building mine for 1 month, can't wait to complete it.
i left off the air intake also.
i went without retracts becuase of the strip i fly off of.

how well dose it roll?
i extended the rudder 5/8 " and plan on running ailerons the
full lenght of the wing. i havn't glued the control surface yet.
will it at least do 1 snap if build to plan ?

i don't plan on making it fly to maximum speed, but more
pattern ship like. it's my first patriot and i wanted to make
it go easy as possible. if all goes well... i'll build another.
hopefully i'll have two and not just another one.lol

That's one of the cleanest covering jobs I've seen. Great job! I'm really glad it doesn't look like the pic on the box, that's a little overdone.

Default RE: Patriot

I'm a slow builder - I try to have one new plane done each year. I started this one in March of 2003 and finished it in March of 2004!! Couldn't even guess at the real number of hours as I worked on it off and on - probably between 75 and a 100 though (although according to my wife, it took about a 1000).

The covering is Ultracote - I really like the stuff. I've had people running their hands across the wing of this plane trying to figure out if it's a sheeted foam wing or not. In sunlight it's hard to tell. I usually spend 10 minutes before I start covering to lightly sand every exposed edge (like along the rib cap strips for instance) which really makes a big difference.

It'll roll very fast if you want it to. I overdid the control throws on my first flights and was literally all over the sky with it - it's a miracle I got it down in on piece. I reduced my control throws and dialed in a lot of exponential which made the plane a real joy to fly.

You'll have fun with your plane - it's a blast. The one thing I've learned so far though is keep your airspeed way up on landing and takeoff. Things get really nasty if you stall it - my landing gear took a beating on the last flight because of that.

I just put an APC 9-8 prop on it. Bought a 9-7 too. I'll try them this weekend and let you guys know how it goes

Just so nobody gets ahead of themselves...

The new larger (60-90) size Patriot is a kit not an ARF

Flew the plane last weekend with the APC 9-8 prop but didn't tach it or mess with the engine much to see what it could do. I was out of town and had taken the plane along to fly for my relatives, so it was still plenty fast for them. I'll play with it again next weekend.

Razor, how about a pic of your Patriot?

Uh.... Whiplash/ Jett-50? Whatever day you wanted to "drag" with the Patriot, I am going to be busy doing stuff- [X(]

Besides you will never actually finish that airplane will ya'?

Airgar, please tell me you will use a different color for the rifle.[&:] I am waiting to see how it comes out. I talked with Angel a couple of days ago about your plane.

To all concerned:

No, the Rifle will NOT be P**K!

Haven't really decided on a color yet, but it will be bright! I have to make a new vertical stab, as the one provided has the grain going the wrong way. (take note Angel) So far, this has been the only issue. I need to go pick up some sheets of balsa as I don't have enuff in stock to re-do it.

Flew the plane a couple more times last weekend. Used an APC 10-8 prop which seems to work the best so far. Really starting to have fun with the plane. Tried a stall at altitude. The left wing dropped fast and the plane reversed direction. It then went totally out of control for a few seconds until I added power and recovered.

I'll take back what I said about the Hobbico retracts - 12 flights so far (off grass and pavement) and they're working well. Not bad for cheapo gear.

Thanks for the pics Razor. Great looking planes!
