Rob,

I think so I'm thinking either the pump or the ecu are giving me reduced range as with the engine running at idle great/fantastic range but at full bore I get a dremating reduction, so I'm gonna try going to the gasbar fadec and see if there is any improvement??. This I think coupled with the fact its a jet meet gave me a very scary moment.

Nice to see ya by the way are you gonna be at the wroughton doo?? I'll be there on the sunday.

Charged my Bandit...and the messed up throttle right Tx

Dave

Yepp, I think Gaspar's ecu is definately worth a try, I think Simjet offer it as an alternate/upgrade, I have Gaspar Fadec's in stock if you have any problems, Lars should be able to sort you out though.

Unfortunately Wroughton is a bit of a hike for us northerners especially as we have an Elvington meet on Sunday.

Have fun.

Rob.

Thats why I'm coming then I just have to persuade the missus its a good idea as I DO NOT WEAR THE TROUSERS IN MY HOUSE its the way to an easy life and get 90% of what I want + she pays for some of it so its a good idea as far as I'm concerned.

Ryan,

I have not talked with the guy who has the Titan in one since November, but remember that you can fly any plane with a Titan in it just as if it had a P-120 in it. Keep the speed under control and use the power for quick acceleration and vertical punch and it should be fine.

On paper the Rhino is 3 lbs higher in thrust than the Titan. From what I've read on here, in practice the Rhino does have more punch than the Titan. I've never had an Artes engine myself though and I'm still waiting for my friend to get his Eagle going so I don't have any first-hand knowledge in that area to share...

My Flash arrived today. I can't wait to get started on it. I have a P-120SE coming for it.

I have a Merlin in my new Jolly Roger Flash and it is off the hook! I turned it down to 30 lbs but it still has almost instant spool up from 1/4 throtte to full and has unlimited verticle to say the least. The orange checker Flash is powered by an Artes Super Eagle and Darcy punished it at Cal Jets last weekend (full throttle multiple snaps and other things jets aren't supposed to do) with no ill effects to the airframe. This is one tough jet!

Hi again, Here is the pic of the bypass on my Flash as I posted a few days ago, I have an Artes Falcon in it and have never had any wet or hot starts. I have only 8 flights on it now, and this occured during the last flying session ( 5 flights) . I have a call into Eric at Jet Central about this, at this point I am grounded until I get the heat problem solved. I am going to try and start it with the bypass cover and wing off and watch to see if there is flaming at any point. If anyone has a brand new Bypass they want to sell let me know. Hopefuly the pipe is OK , it is not distorted, but it is very slightly light blue at the turbine end. Thanks for the help, Jack.

Here is one more , Jack

YOUR ARE GOING TO LOVE IT!!

I tried to maiden my flash last eve but on the takeoff run the right 6mm pin in the C-36 landing gear broke and I had to abort. No damage to the plane at all but I will be replacing all of the pins with better ones! My field is grass and a bit on the rough side due to spring thaw here on the east coast. The pins were the ones that came from C-arf with the retracts!!
will try again soon

When you filed the "flat" on the pins, did you cut a notch? If you did, you might have caused a stress point that led to the failure. Dave mentioned this before in this thread. You need to make the "flats" as shallow as possible and still have them do their job and taper them gradually out at the ends.

I have flown my Flash off a grass field several times and did not have any problems with the gear pins.

Bob

Jack,

I would definately start the engine several times and make sure its not "flaming" during startup. The fact that it does, if it does, is not an indication that it is bad, it may simply be that an ECU parameter or two is off.

I'm not sure that a new bypass is really necessary, but I would post a picture or two of the pipe and let those here that have had a pipe collapse give their opinion on whether or not its OK. The fact that it does have support at the front end, where its blue, may mean that's its OK, but I'm not an expert in that area.

Bob

no just flats... they broke at the joint line and the metal appears to be brittle..I will replace them and try soon

Thanks, Bob for your help, I will run it without the wing and bypass cover to see what is going on ,Thanks Again , Jack.

Guys,

Any idea which ROBART retracts \ struts are best suited for the FLASH ?

Are any of you Flash owners have any heat issues in fuse above the tailpipe?

Quist,

If you cut the additional NACA ducts as mentioned on the underside, the tail should run cool.

We have found some issues with the top of the tailplane getting marked from the Ally outer pipe as it is extreamly close and heat marks starting to show on the top surface of the centre section of the tailplane.
To get over this, we now install a small amount of ceramic blanket between the pipe and the tailplane to cure the problem.

Hi modtron,
How have you attached the ceramic sheet to the pipe, and how far does it go along the pipe? I'm almost ready for a first start, may as well sort it now. Powered by 120 Jet Cat. (have done the NACA ducts.)
cheers Grant

Hi Legnum,

We cut some thin ceramic sheet (BVM) to 170mm long by 160mm wide at the front edge tappering to 140mm at the rear.

It slips under the flanges at the fuselage / tail area and rest against the outer ally pipe.

You will need a small cut for the elevator servo cables to pass through.

It's a tight squeeze, but it does stop any marking or scorching to the tailplane top.

I used the same Ceramic blanket on mine, when I noticed a small deprssion from heat in the top of the stab where the pipe passes over it , since installing the blanket material all has been fine with the stab. Jack.

Modtron,

You're the man ,cheers dude!

Tam makes a dual wall pipe that is smaller in diameter than the C-ARF outer pipe and is 5oz lighter, I have one in my Flash and there is a lot more clearance from the stab.

Marvin Jones

Hi Modtron,
Thanks for your reply and help.
regards Grant from NZ

I had a great time with the Flash at BITW last weekend. A total surprise to me to win best turbine. I'm really lovin this jet! I also used BVM heat blanket on the top of the pipe at the rear and on the stab secured with aluminum tape. I didn't use the bypass or cut any holes in the fuse. After about 12 flights with the Merlin I have no heat issues. You can lay your hand on the fuse after a hard run and it is only warm. Darcy Wingo has the same setup on his Flash powered by a Super Eagle with about 80 flights and zero issues. We pulled his stab off after about 25 flights to check for any heat related issues and all looked perfect.
