The field is over in Richmond near the water. There is dry grass around. There was a crash of an electric foamy. The lipo battery caught fire and burned several acres of scrub grass. The fire department put out the fire. The club banned turbines in reponse to this lipo caused fire. It would be ironic if I avoided using a turbine and end up using even larger lipo batteries.

Let me get this straight. A Li-Po powered foamie crashes and a fire ensues. Several acres are burned and the club bans turbines? Who's the President of you club? Nancy Pelosi or Diane Feinstein

rE-action

I reduced the size to reduce the weight of the airframe. I am looking at between 8 and 12 lb thrust from the fan. 12s 5000 batteries weigh 5 pounds and right now my airframe weighs 6. That means that ready for flight I'm looking at probably 13 vs over 20 for the full size. I may drop to 8, 9, or 10s - don't know until I get it done and out to the field. Body is 8.38 high X 5 in wide.

Obviously not all of the woodwork is done and the corners have not been rounded. I think that my router will make short work of the corners. The batteries are in for size comparison. The fan mount and housing is a work in progress.

I can see reacting to the turbines potential to cause a fire in the event of a crash as remote as it is. Did anyone discuss banning electrics also since the original problem was created by an electric? At least a turbine engine can be shut down in the event of a problem. You can't make a Li Po safer in a crash. I forsee a hand launch glider club emerging.

You're right Mark. My bad. Pelosi or Feinstein would have just taxed turbine flying to subsidize the local Fire department or just outlawed RC flying there as it is endangering a rare species of nat that serves no other purpose than to fly into your eye while you're on finals

It has been a while since it has flown but I took the old Supersport powered R54 out this weekend. I have not flown it for about 6 months, but it flew as well as ever, Fast, Smooth and landed like a feather.
What a great model.

Regards

Before and after photos of my 82% reduced size Reaction for EDF. I used a router with a 5/8" roundover bit to create the corners on the body. This was a very fast way to do this job. It gave very good results with a nice smooth curve over the corners.

Hello All. I've been flying my R-54 and finding it a real pleasure, however my landings need ALOT! of help. My approaches are fine but when I get close to the runway surface the plane becomes very pitch sensative. I've played with elevator expo all the way from 30% to 70% (JR 9303) to no avail. I have rechecked the CG and it's within range but at the rear of the recommended. My guess is that I need to move the CG to the forward extreme at 6" from the wing L.E. I sure would appreciate any guidance from you seasoned R-54 pilots. Last weekend at the New England Jet Rally I got a lot of help from more experienced pilots but never got the chance to fly again due to a stiff cross wind.

John,
A slightly forward CG does help. Make sure you are getting slow enough on the touchdown. DON"T dive for the runway. Establish a slightly nose high final approach, control descent with power, speed with elevator. When over the threshold, cut power and gently continue to add up elevator all the way to touchdown. Don't force it down by any means. It is eaier to add a touch of power for a slightly short approach than to try and bleed off excess airspeed.
I used Bruce's flap settings and never did try CROW. Hang in there! She's a GREAT flying plane!

John,

I am using 1/4" of crow and it seems to help. One thing that I read somewhere (can't remember where) is that when on final, you don't want to be able to see the top or bottom of the airplane. If you see the top, you are to fast. See the bottom, you and you are to slow. My CG is at the rear limit. My elevator is set to Bruce's recommended throws and I run 40% expo up and 15% down.

Once over the threshold, at about 10 feet AGL, I wipe the throttle. Then I feed in up elevator and bring the nose down but I try to keep it off the ground as long as possible. Then it touches down and rolls out about 20 feet.

Another thing. I installed a Prolink front strut from Dreamworks with a 2.25" wheel. This lets the nose sit lower a little. I think that it totally eliminated the tendency for the airplane to take of again if I touch down a little fast. My feeling is that it lowered the wing's angle of attack when on the ground.

I see that you live in Connecticut. You should try to make our jet event in October and Farview. I will have my R54 and there were 3 others here last year. The invitation goes out to everyone, by the way! www.farviewflyers.net
