Bah I no longer have a firebird and am going to sell my throttle ring to MF dude.

He he.

I've also have a "skyfly" which is basically the same thing. It flew terrible.

Maybe a nice pee wee would fix it eh?

Possibly. The main issue was it took nearly whole football field to turn around. Do they make Peewees with brass driveplates?

No they don't but I'm sure if you know a guy with a lathe he can make Ine jingle you very easily and quickly.
Maybe if younkers an adjustable engine mount it would be easier to turn?

hey guys, just a quick update. plane is just at 8oz with all exept the bat and RX. still waiting on those... damn you post! Mad

Should be a spirited flyer then Smile

Ok, so this might sound a tad odd, but is there any way to slow the flight of an rc plane with no throttle? Like do bigger wings decrease flight speed? Im sure i read that a bigger prob gives more pull and less speed? Is there any truth to this?

Yes a larger lower pitched prop could be good or you could use an exhaust screen to restrict the power.

There are other thing like simply running it a little rich.

shell shock Sat Oct 22, 2011 12:26 pm

He he, im already running 10% nitro. i think that also helps XP

Yep it may make NV settings a little fidly.

When nitroairplane saw the title of this thread nitroairplane thought that shell shock was going to be like thunderbirdjunkie and like nitroairplane when he is thinking of thunderbirdjunkie.

shell shock Sat Oct 22, 2011 1:12 pm

explain? my brain is to fried from work

There is a guy on RC universe called thunderbirdjunkie always talks in 3rd person he has over 20,000 posts all in third person.
I sometimes do that and i though from the title that you did too.

Shell, another way to reduce airspeed is to put the prop on backwards. This tends to kill prop efficiency/thrust but still allows an optimum needle setting for a reliable run. Ken Willard used to suggest this for some of his early .010 planes. They were rudder only and needed to be trimmed out reasonably close just in order to complete a flight. The CG, incidence and engine thrust angles had to be set up. It was considered prudent to reduce thrust for at least the test flights.

Yes this was also recommended for the Page Boy it was at one time the worlds smallest rc plane with a reduced wingspan of only 8".

shell shock Sun Oct 23, 2011 1:00 pm

oh wow! 8"? my elevators are longer then that! X)
I will definatly try the prop backwards. Also PICS!

Well tell us how it flies when you get it out.
Also make sure you cover those wings with something e.g epoxy or the fuel will effect them.

shell shock Mon Oct 24, 2011 8:43 am

i got the plane all covered in fuel proof epoxy. still has a beautiful wood, but will eventually cover in yellow and black (calling it the hornet)

nitroairplane Mon Oct 24, 2011 8:46 am

Nice that's a good name and rather fitting.

shell shock Mon Oct 24, 2011 9:04 am

^_^ danke. Ok, so before i finalize everything, what is this thrust angle (and incidence i think) that i hear every once in a while?

WELL NOW! I have just installed the last of the hardware! woooo. I will be taking her out for her maiden voyage tomm. I will have video of the flight (or lack off)

STAY TUNED!

Awesome! Can't wait.

I hope your maiden will be better than mine. Shocked

**RknRusty** Tue Oct 25, 2011 11:46 am

Can't wait.
Don't put a hot prop on it for the first flight, or either put it on backwards. That way if balance or something makes it too squirrelly to handle it'll be easier to hang on to until the gas runs out. First hand experience. Very Happy
