Can anyone suggest an electric conversion to this popular SIG Kit?

Post some specifics on it, and we can work something out.

IIRC, this is a .40-size airplane, and a little hotrod at that. I'd recommend you look at "16 cell" power systems, that is, power systems based on a 16-cell NiCd or NiMH pack. One option is the AXi 4120/14 with a 12x8 prop, direct drive. For a little less power and a little less weight, check out the Jeti 45/3. There are literally hundreds of geared options as well using Hacker, Kontronik, Mega, and other brand motors that will work equally well. I prefer to stick with the direct drive AXis because there's less to remember, they're inexpensive, and they do the job admirably.

Matt,
Here are a few specs

55.5 in. wingspan
575 in^2 wingarea
22 oz. wing loading at 5.5 lbs for glow powered flight.

I would like to use a li-poly setup for this plane, could you make any suggestions for a power-setup please?

I am going to use this plane as an intermeidate plane, so I am not looking for blazing speed, or top preformance.

Thanks a lot for your help

I've almost completed a glow Kavalier kit and expect it to fly weekend after next. I'm going to use a .56 four stroke and that may be underpowering it. I think the 5.5 lb weight may be a little optimistic, but I could be wrong. There is a lot of wood in the Kavalier. There are some places you could lighten it as you build it, but I didn't do that. I built mine stock.

I will be very interested in how yours builds and flies.
