How many of you guys are flying your Flashes with a Falcon or P-70 or comprable turbine size and how do you like them. Are they lacking power are you wanting more power??? I searched and it seems alot of people are using P-120's and up.... I was thinking about getting one as my jet that I dont have to worry about gear doors and other scale stuff... Tell me what you think...

Falcon or a 70 would not be enough peppa in my book... I have a TITAN in mine and it scoots along just fine. They fly great with a P-120 as well..

2 cents

David, if you are planning to fly conservative and not looking for a flying missile then the Falcon is a perfect match for the flash. Just a bit larger than P-70 but with 23 pounds of thrust and very fast respond. You will still have good verticals and great flying with that combination. I will put an Super Eagle in mine just because I allredy have it.

Good luck,
Alex

Have fun with that combo!!!! Boring....[)] Putt Putt Putt!!![)]

I have a Falcon in mine but only have three flights and won't get any more for a couple of weeks. It may not be the fastest but it is fast and you can still fly most of the flight below 3/4 throttle. Even at half throttle roll rate is about 2 per second and it tracks straight as an arrow. Even with the bigger engines it won't go that much faster because of the thick wing. Better verticals but from full throttle goes higher than I want anyway before pulling out of the climb.

My buddy has a P120 in a Viper and I think it's at least as fast or faster for a comparison.

If you just want ot go fast... booorring

There are now two Flashes in my club. Both were out yesterday. The one with the P-120 goes like hell, close to 200 mph. The other one was flown for the first time with a Jet Central Rino (37#). Suprisingly it didn't seem any faster than the one with the P-120.

the fat wing on the flash makes it draggy, a P-70 flies it fine and has decent speed, the advantage of the larger turbines comes in with exceptional vertical performance but only a slightly higher top end speed. the fuel economy of the P-70 is a definite advantage, you can get by without the wing tank and save some weight.

Boring or not all depend of your flying style. It's still a good combo for conservative flying. For ballistic go anything bigger. If that is the case, then go eagle instead of the falcon.

I think jetspud already has a Falcon as I did and no need to buy a new engine just for this plane.

Hey Joe, did the Flash with the Rhino have the full bypass? If it did the engine won't perform to max according to Eric Clapp.

David:

Hello. I have flown my Flash first with the Falcon which performs outstanding and will give you all the vertical yours eyes will allow. . .no slouch here. You will get a solid 8 minute flight with the two tanks and UAT. After flying it for almost a year, I switched to the Super Eagle with 30 lb of thrust. First flight proved very, very fast. I then reduced the maximum RPM from 128,000 down to 124,000 giving 25lb thrust. Some interesting data surfaced as a result of this change.

1. Jet still very fast. . .more speed vertical than that of the Falcon
2. Fuel consumption went down. . .I can get consistant 10 minute flights with fuel to spare
3. Turbine runs cooler which is good for the turbine and good for the fuselage.

The Flash is a well engineered and fun jet to fly. It does have a very narrow CG from nose heavy to tail heavy, but very easy to reach.

Bottom line is go larger and use less fuel. . .go with the Falcon and get great performance with normal fuel consumption and flights of 8 minutes with reserve.

Last, test with both turbines proved each performed far better without the bypass than with. The inlets on the Flash IMO are small and the turbine(s) need all the air they can get. Use the bottom half of the bypass and leave the top half on the bench.

Any questions, feel free to give me a call. 941.468.1246 or 941.423.9931

Eric,

which half of the bypass are you calling the bottom? Is it the half that is bolted to the fuselage or the half that is held on by the velcro strap?

Lin

the bottom is attached to the fuselage, the top is velcro'd on, and should be removed for optimal performance, it allows the turbine more air.

Kc36330 is correct. . .try it and you will be quite surprised. Also a benefit during cool down.

The bottom half is actually the upper one when fuse is on its wheels.

kinda hard to work on it with the wing attached and it sitting on the wheels.

Thanks for the help guys. When I take off the bypass shell, should I aslo take off the Y-pipe that channels the air from the inlets to the bypass?

Yes. Next time out he's going to try it without the bypass cover.

Joe

No.

Thanks KC36330. I appreciate the help.
