Default Fuel consumption in a Patriot

I just ran the Novarossi 50 in my new Patriot. I didnt time how long It was running, but it was probably only a minute. When I sucked the fuel out it was almost empty. The tank is only 8 oz. I think I can sqeeze in a 4oz in front of the 8 if I have to. Just curious how much flight time everybody else is getting on 8 oz tanks? Is the Novarossi just a fuel hog? For those curious I did stick a tach on it. It turned 16,740 on a 10-6 APC. I think it has more left in it. Not sure how good that is. I've never had a speedy airplane before.

Default Fuel flow

Hi Fred,

At full throttle a hot 50 sucks a bucket load of fuel!

As a guide a Jett 50 will go through 6 ounces in around three minutes at full throttle. When I fly my Diamond Dust I use partial throttle between my full throttle high-speed passes. I set my timer for 3 1/2 minutes and land with no more than about 1/4 inch of fuel left.

I wouldn't expect to fly any more than 4-5 minutes on 8 oz with that motor depending on how much full throttle you use.

Got a photo of your Patriot?

Am about half way done with mine and have a Jett BSE 90L FIRE on order for it.

Your Dad will think I've gone bonkers for sure (Yeah, I know, he knows that already!)

Good flying with your Patriot.

Gene

Default Hmm..

Sounds like bad mileage to me- depends on the motor though...

Throttle management is the key here, also I have a 2 oz. header tank in mine which helps keep the main tank (8 oz.) nearer to the CG and increases the flight time-

Good luck and pleasepost pics!

Default hopper tank setup

i am building a patriot with a 4 oz hopper tank up front and a 10 oz cylindrical (round) Sullivan tank near the CG location in the fuse (fits perfectly)

the (exhaust) pressurized system should work fine, but depending on the engine and the setup you might consider adding a pump.

see pic in post no.3 here:

http://www.rcuniverse.com/showthread...ht=hopper+tank

the plane will be a little heavier on takeoffs but since the bigger tank is located near the CG it wont affect the ballance that much

this way you don't have to think of the "landing time" all the time and enjoy the thrill of flying the Patriot! D

Default pictures

I'm picking up the lettering I had made in the morning. When I get it on the airplane I'll post a picture. It is done in the navy trainer orange and white. Might fly it tomorrow if the rain and wind stop. Think I'll time how long the fuel lasts before I fly.

fred......

How do you like the Novarossi so far? I'm about to put one on a new GP Tracer and would appreciate any tips/hints you might have.

Thanks,
Beau

Default flight report

I got a few flights on the Patriot today. First flight had radio glitches. Turns out the header was vibrating against the engine. It uses a spring to hold it on. I put a rubber washer in between and the problem went away. The radio problem made the first flight interesting. Anyway the second flight was much better. It is plenty fast for the limited airspace we have a t our field. Engine is turning 16,900 on APC 10-6. How fast does that equal to? Airplane is a lot of fun. I usually fly 35% aerobatic stuff. Big change from that. My airplane is probably heavier than most because of the Novarossi weight. I had to put 5 oz in the tail to balance. Landings are a little hotter than an average sport plane, but nothing outrageous. I was landing with about a 25 foot roll out on asphalt. Very dossle at slow speed. As for high speed, it would knife edge and slow roll with hardly any rudder input. It can climb in knife edge, so the rudder is very effective. It wants to roll right side up when you hit the rudder. As long as the speed is up you can slow roll and point roll without touching the rudder and it tracks beautifully. I'm quite happy with it so far. Probably will be for sale at the end of the summer if anyone is interested. I usually only fly a plane for a few months before I move on. Hey Gene, looking forward to seeing yours with the 90 fly. You have to get working on it. I'll be the area probably sometime at the end of summer.

Let me know what you want for it before you sell it. Maybe we can work a trade or something.

Default Fuel consumption in a Patriot

I am in the final stages of completing my Patriot kit, and spent many hours contemplating the fuel consumption/fuel tank issues for this airframe. I am a firm believer in the KISS principle, so a header/main tank setup was not considered because of the complexity (Yeah, yeah, it's not really that big a deal). I found that the 11 oz. tank that Hangar9 supplies with their 40 size kits (Aresti, UltraStik) fits right into the Patriot's fuel tank compartment.

Unfortunately, I had to sacrifice my Aresti to the dirt godsto obtain the "free" tank for the fit testing.

Default speed

10X6 at 16,900 gives you 96 mph. Put her in a dive and break into triple digits. Does it unload much in the air?

96 is pitiful. I used to own a radar gun and have gotten 35% aerobatic airplanes over 100. I believe, you but it seems faster than that.

Default 6 inch pitch

6 inch pitch will not get you anywhere fast. Just curious, what pitch does a 35% plane run?

I would try a 9X9APC. Your take off will be longer but look out when it winds up. I had one in a patriot with a 46FX and it was well over 100MPH.

The airplane I radared was an Extra 260. It had a D&B 3.7 turning a 22-12 Bolly prop. Probably close to 7000 RPM. That is not a normal giant scale aerobat. Most fly under 90 mph. The Patriot is way faster. I still have a radar gun, but it is attached to my police car. I'll have to bring to car out to the field and see how fast it really is. Also forgot to mention the fuel burn. It has plenty for a 5 min flight. I got a 9-8 APc the other day and will try that.
