The ECO 8 from Ikarus was my second helicopter but my first electric model. I have used the Brushless motor option and aluminium swash plate to allow 120 degree E-CCPM with my JR X652 Transmitter, which I have since changed for the JR X3810.
I purchased my ECO 8 as a complete deal from The Model Shop
, 88 Crossgates Road, Leeds (Tel. 01132 646117).
It is based on the J. Perkins Distribution Ltd. deal in their New Items 2000 catalogue where you get:
ECO 6 kit, Sanyo 9.6V 1900mAH battery, GWS PG-03 gyro, Speed EX charger, GWS 8ch 35Mhz FM Micro RX, Heli Sport Motor, Heli 4000 speed controller and four SuperTec Naro MAX/BB Servos. (List price £399, shop price £345)
I asked the shop to replace the Heli Sport motor and Heli 4000 speed controller for the X250-4H brushless motor and V45 brushless speed controller. I already had a good charger, so swapped the one in the deal for the cost of the 120-degree aluminium swash plate. (I already had the JR XP652 TX.) They did the complete deal for about £430.
They provided a free set-up service, during which they selected the 15-pinion gear for the motor. This gives me a flight time of about 8 to 10 minutes with the 8-cell 1900 mAH battery.
Tips & Hints
- I found that you should not run the receiver aerial (if 35MHz) parallel to the tail boom! I had lots of glitches when it was fastened to the tail fin so I put it in a tube strapped to the RH under carriage legs and now I get no glitching (which caused the model to act as though the motor had stopped!).
- Fit the glass fibre rotor blades! They make the ECO much better (more stable) to fly.
- The auto hub is a good idea even if you can't do autos!
- The aluminium swash plate is also a good idea as its more robust than the stock plastic part. (But if you have a TX which supports 90 degree CCPM mixing then use it till it breaks!)The ball links can be a very tight fit! Either sand the balls for a nice smooth free fit or use a ball link sizing tool to open them out. Any stiffness will lead to difficult control! (Not a good idea if you are trying to learn!)
Although still available, in a slightly different form, it has been completely overtaken by more modern 450 to 500 size replacements from other manufacturers. A Blade 500 is similar but a lot more expensive!
