EasyBug Elevon Reflex?


The manual doesn't touch on this but on my maiden it required full up trim to maintain level flight. Does anyone know how much I should put in?

How does it fly inverted ???? If it tries to become a dirt dart, then move the CG back. It should not need any up trim if the CG is right.

I had that problem. It tucked on me until I moved the CG back. Good luck this is an awesome model!

Really, move the CG back, huh? It's currently right on the mid-mark as described in the manual. I'll try the CG though.

This Bug is awsome, I have about 20 (twenty) hours flight time on her using the same stock 350 motor and a couple HD 1060 props. Using the CG recommended from the manual, my elevons are about 1/4" up to maintain level flight, inverted flight is no problem but the outside loop is not easy (for my EasyBug), roll is not axel and she is a perfect hovering bug.

Here's my setup:
Stock 350 motor, "C" gear
HD 1060 prop on GWS prop saver
3 pico servos
Pixie 7 esc
2S lipo (Kokam 340 or Irate 830)
AUW with LG is 9.8 oz W/340 lipo and 10.5oz W/830

Now, I'm flying her using the cd-rom brushless motor and the flying character is a little bit different, the stock motor system has lots of thrust and the cd-rom brushless is like a silent and speedy flight.

WOW!! 9.8 oz!?! Mine weighs 8 oz with stock motor and 2s 1500 kokams!

Where could all that extra weight have come from?

Maybe the foam is different? Mine weights 9.5 with 2s 1100 irate.

How many people need reflex and how many don't?

Random Flier

Reflex = yes


Mine does too. Can't remember the CofG location, but am using:
- stock 350 + HD9050 + CC Pixie20
- Ko 1500 3S
- Berg / Schulze micro receiver
- some added tape on the wings
- no rudder servo (not got round to fitting it yet - will probably not now, and get a Pizza to try that out)
- a little tail down (-ve reflex) in the foam between the elevons - due to stepping on the trailing RX lead that was taped to this bit

= 1/4 to 1/2" reflex to trim

Performance ++ although of course with 3S I limit WOT
- inside / outside loops fine
- inverted flight a bit squirelly (likely due to pilot )
- ROG in ~3', even on thick grass
- good vertical performance (black tape underneath helps with orientation at altitude!)
- supremely crashworthy (although I'd like to get some thin / 3mm Depron to try some alternative wing shapes / replace the taped up wing rips !)

So I moved my pack back to move the CG back and now it is at the back end of the recommended CG and still requires about 1/2 inch of elevon reflex for level flight at anything but full throttle.

Do others use even further back CGs or what?

When I fly her with the stock motor, I place the pack all the way to back in the battery compartment and sometimes I put the pack on top of the radio compartment.

Now with the cd rom BL, I move the pack all the way to the front and sometimes covering the landing gear mount, the elevons are set at 1/8" up to fly level at about 1/2 throttle. I'm kind of miss the flying characteristic with the stock motor/gb since the thrust and the power curve is much better.

I always fly her with the landing gear and it looks better in the air.
