Status: offline 		Heres another thing I am trying to work out, weather or not to put the ignition module and ignition battery in or outside the engine box.

So the question is, which way you guys prefer it, In or out of the box? ( Boy, thats a loaded question)

It looks like the bottom has no room for it. The sides are bad because it's a twin and the plugs are on both sides.

I would install it protected inside the motor box and drill two holes on the sides for the leads going to the cylinders.

I would wait and see how the Model is going to Balance out before deciding the Location of the Ignition unit.

If it is like Most of the 100cc Models the Outside of the Engine Box on the side works.

This way you would get airflow around it. Especially good if you have a Lith Ion with a Regulator setup.

Status: offline 		Hey guys, thanks for the response,

I have done it both ways with-out any failures. My 102" QQ Yak has module on the outside w/ battery & regulator. My AW QB Extra 260 had the ignition gear inside of the box.

On this project I am opting to go with NiMh 1900-2700 mah battery. I am not going to put an on/off switch or regulator. Since I have a Smart-Fly Optical Cut-off switch. I can shut the ignition down with this at the field. I just got to unplug the battery when I get done flying. By eliminating the switch and regulator it will be as light as a 1900 mah li-po w/ reg and switch, and I eliminate two potential failure points.

One of my flying buds VooDoo aka Krillbill, had his Fromeco Regulators fail........twice, causing him much damage to his brand new 35% Krill Katana. The plane has been repaired and flying again. But needless to say, he almost lost the plane all together.

I will probably just put the module on top of the box, so I would not have to drill out a big hole on the sides of the motor box for the plug wires. I will put the NiMH batter inside the box next to the Smart-Fly Optical Cut-off receiver, this should help keep the battery cool and away from the heat of the engine.

I already have two Duralite 4000 mah Lith-ion redundant batteries and will be using them on my Duralite 40/16 Power box. I will mount those last after the whole plane is almost put together so I can adjust for CG. With Carbon fiber pipes, I may not need to mount these batteries too far forward.

Do you need to drill an exit hole in you tailgear strut to pull the pin out through the bottom?
How to you keep the pin in once you push it in?

Thanks!


It depends upon the tailwheel style and how the it is mounted. If you use a Haigh style tailwheel then you definately won't need to remove the tailwheel. If there is enough distance between the bottom of the rudder and the tailwheel struct to bend the wire to one side then it will be easy to slide the music wire hinge out the bottom.

Status: offline 		Hey All,

Well the weekend was very busy. Unfortunately very little had to do with building, much less flying. Anyway I did find sometime to make a little progress tonight. Got the stabs assembled, sealed the hinge lines, and ready to bolt on the plane. Assembly was pretty straight forward and very much like the 88" Yak except bigger. Same single drop servo, root mounted design.
