Eliminating the AR635 AS3X Receiver

Thanks,
DD


My Splendor had aileron flutter at anything over half throttle in the F3A flight mode. I tried several things to solve this and it only got worse. 3 days ago I swapped out the 635 receiver for the AR610 and that solved the problem instantly. I moved the clevises in one hole on the ailerons I set Aileron and elevator travel at 70% and set Expo on both at 25%. It's flying really good now. One more thing. I recommend eliminating the switch on the lower right side of the cowl. Just cut and tape both wires. That switch cost me my first Splendor when it cut-off in the air. Best Regards JC

Did you adjust travel in servo settings to 70% or set rates to 70%?

Installing a uBEC took the switch out of the circuit.

Hello Fellow Eflite Splendor Owners - I picked up one of these second hand the other day at a show. I am planning on using the included BEC to power my Hitec Optima 6. Im guessing there will be a good UBEC in the supplied ESC.

Also, I am planning on running a Gens Ace 5000mah 6s pack. Has anyone one a 5000mah 6s in this? I'm guessing it will fly.... But may not be so good for 3d....

Thoughts....

Centre of Gravity

Hi Chaps,

I know there is a lot of talk on this thread with moving the battery back to improve the flight characteristics of this wonderful plane, especially for people using larger batteries. My question, as opposed to how much you moved the battery, what was the resulting center of gravity measurement in mm from the leading edge that you found to be optimal? I am running mine with the recommended E-Flite 3200 six cell batteries and have not yet moved the battery but might like to experiment shifting the weight back a little.

many thanks

~Tom

I had it sitting on my shelf. I think it was called a Sullivan tail wheel purchased from Tower Hobbies.

No difference for me with battery placement with 3,300 or 4,000 packs. I use the morgan mill lipo tray to mount the pack. A 5,000 pack would make a difference I expect, and I would expect you would need to move the pack aft to maintain the CG.

Are you using the Carbon Cub battery tray from Morgan Mill in your Splendor?

I reduced servo travel to 70% and I set Expo at 25% to reduce sensitivity around neutral. The Splendor has very large control surfaces which are probably needed for 3-D flying which I don't do. I'm an old Pattern Pilot and still prefer to fly those type maneuvers. My plane still has a high roll-rate, even with the reduced aileron travel.
With regard to LiPo battery location. I removed the foam in the rear of the battery area about 1/2 inch...back to the plastic wing spar. I haven't checked the CG, but I like the way the plane flies with this battery placement. IMO the plane is nose heavy unless the battery is moved to the rear. I am using Turnigy and Glacier 6s batteries.
Regards
JC

Could you post a picture of the Morgan Mill tray installed in your Splendor?

Aerobatic maneuvers are improved by by moving the center of gravity as far aft as possible without compromising pitch stability and making the airplane unsafe in slow flight. This reduces the work the horizontal tail has to do to keep the airplane balanced in turns. Reducing the workload of the tail reduces drag. Anytime we pull back on the stick, the elevator deflection increases drag. Anytime you can make a maneuver with the least amount of control deflection—the least amount of drag—that’s your goal in most F3-A type pattern flying. Of course 3D is a different ballgame. JC

Thanks for the information. I'm guessing it's still safe ish to fly with a 5000mah in the standard battery position, but it wont be optimal. The motor seems mega powerful so it should handle the extra weight no problem. I dont want ot particularly weaken the structure by removing foam to move the battery further aft.

I'll give it a bash, well, not literally!

not only that, but ..

.. Stock 3300 6S batts, even with the foam cut back to the spar, require you to carry some up trim to maintain level flight meaning that the CG is still too far forward.

Can you fly like that ? Sure, but again you are inducing un-needed drag in upright horizontal flight, and inducing a pitch to canopy in any knife-edge maneuver, and inverted flight will require substantial down stick instead of a slight amount.

This will only be exacerbated when flying with heavier than stock batteries in the stock or slightly aft (foam removed back to spar) location because it will require even more up trim for level flight.
