Default RCM FIRESTREAK

I would like to know if anyone here has built the RCM / Joe Mergen FIRESTREAK? I have one that I built in 1982 and never flew because of fuel problems. I would like to try it again if someone could give me some tips.

I have a firestreak enlarged to .40 size.
I have the unfinished plane for 25 years and I am working on it now.

Sorry, Sorry, your right. i sure like to see you Firestreak.
Mine is sprayed yesterday, I am thinking to electrofy it with a 800 watt brusless and a 5 cell 4000 batterypack.

Did you enlarge the plan or did you buy the enlarged plan that was out?

Electric may be the way to go as a glow engine will not run with the tank location even with a Robart pump. I was told that a Cline PCFS fuel regulator would take care of this but they are $70.0

This is a picture of a picture because I was to lazy to get it out and clean it up!

Looks good
Electro has also the advantage of easely changing the rotation direction, you can use normal non-pusher props.
This motor I like to use:Turnigy 50-45 890kv with a 5 cell 5000 lipo.
Has our plane a rudder?

I used mechanical Vtail mixing but with the new radios just mix it with the radio!

ok walther, but is the rudder function effective because of the smal v-angle of the tailplane. And do you have nose wheel controle?
I am also interested in the angle of attack of the landing gear during take off because of the limited rotation possibility because of the prop at the back. I still have to made the landing gear. I don't have a drawing

Nic;

I don't see that the V tail is a problem but I never flew this model because of the fuel problem. I do have steerable nose wheel but will have to set it up and check the angle of attack, but it is positive. I will also check the length of the gear legs and you can scale them up. The tail should have a skid built into it.

Hello,
I am a bit further now, the c.g. is a bit to far I think, It's on the gear now without the (heavy 280 gr motor). So I think electrifien it is the best optien I can then put the batterie (560 gr) in front.

Hi Walther and nicohaas
That is an exciting plane. If you ever want to use a glow engine, you can look up my Building the Spad Canard. It uses an OS46FX engine in pusher configuration. The main fuel tank is in front of the main wing so it too had a fuel problem. I solved the problem by adding a 1 or 2 oz fuel tank just to the front of the engine. I have been flying it that way for about 6 years. No fuel problem.

Just like the small feeder tank at a heli, I did't know that.
too late now I just bought the electroset for this plane.
this has a further advantage for the CG , I can shift with the batterie now , don't have to put lead in it. And I don't need a pusher prop.

Murdoc;

let me know if you build the .15 size or if you find the plans for the .40 size. I would be interested in the .40 size plans.

I think there are no .40 plans, you have to blow them up yourself, i'll look if I can find something somewhere.
Here are two pics of my electro configuration

Will do I`m going to build the 15 size first, and then enlarge the plans so it will fly with a 70 4stroke.

Made the maiden flight last saterday.
Flight caracteristics are very good. Power is far enough. Rotation angle at the concrete runway was good.
After take off you can power down imediatly.
But.... In the landing things went wrong, I had a 30 degree crosswind and because of the big vertical tail surface it was difficult to line up.
I made a crash landing beside of the runway.
Landing gear brok out and the vertical fin broke in pieces.
I'am reparing it now.
