Tell us a bit more. How did you find the quality of the plane. Presume its a bit early for a flight report? Your grass is too green. Don't they have water restrictions in Cairns?

Its a good quality ARF kit, I was impressed with the amount of hardware supplied.
This includes all fittings for the closed loop cable system and exit tubes preinstalled. There are also cut-outs for pushrods to the elevator and rudder if you want to use them. CA hinges are provided for the control surfaces. Alloy undercarriage and light weight wheels.
Construction is balsa ply fuse and foam core balsa sheeted wings covered in Ultracote.
Top quality fibreglass cowl and wheel pants.

Span 1600mm / 63
Length 1460mm / 57

Ive recently transferred down to Rocky so the colour of the grass in the pics will be changing!

Thank's mike, I was lucky enough to have a friend hand machine some motor mounts from a block of alloy for me.
The one shown on the extra is light weight and he also made a radial mount / heat sink I have planed for another higher powered project running the CY 160 more towards it maximum rating.

Here are a few more photo's of the progress

This shows a few of the mods for the conversion.

Normally the bottom wing cover is glued in place, I made his removable by installing locating pins at the front and making a ply bracket for the standard wing bolts. This bracket has 1/4" threads tapped into it for the nylon bolts that secure the back of cover. With the removable wing it is a lot easier to transport and allows access for battery pack.

A small hatch in the cowling was also made for access to the Deans connectors and an exit vent installed for cooling.

There is plenty of room inside for electronics, the rear of the battery pack is just visible in this shot. With the 8s2p Polyquest pack mounted at the front the plane balances right on the 100mm from L/E location. For fine COG adjustments I can move the Kan 650 RX pack.

I've also made the cockpit floors, both are removable, the rear give access to the top of the relocated servo tray for maintenance. The RX pack voltage monitor is located in the front tray.

This is the Polyquest 8s2P 2600 arrangement with 1/8" balsa strips in-between to help cooling. The pack weighs 980 grams. They came from www.aircraft-world.com on special, Bargin!

Wow, that is some battery pack! How do you charge? Do you use the TAPS or the Deans?

Hi Rene, I'm charging via the Deans connector at the moment, 33.6 volts.
I'll use the taps for checking the balance of each cell.

Gary.
