Status: offline 		I have recently accuired a Sig Wonder. I was thinking of building it as an electric but I know nothing about electrics. Looking at the plans it appears quite a bit of weight could be removed if that is a factor.
Any help with this matter would be greatly appreciated ie: components, set-up etc.

Status: offline 		what is the wieght on the bare air frame? What size cells will fit and last but not least.....how much money do you have for a power plant? I have converted a Sig Kobra ( 44 inch wing ) to electric with a speed 400 size brushless and gear box.

Are you looking for speed or just to fly? I guess you have to figure out what you want and how much you are willing to spend and then go from there.

Hope this helps

Status: offline 		Hi Dennis, thank you for your reply.

The weight on the box is 26-38oz. but I am assuming that is with a glow engine mounted, they recommend a glow in the range of .09-.19 I would think 38oz. corresponds with the .19 sized engine but I'm not sure. I also don't know what a .19 sized engine would weigh.

As far as cell size that would fit I'm also not sure, the fuselage bay is about

Length: 11 1/4"
Width: 2 1/4"
Height: 2 1/4"

but I don't know anything about electrics so I could'nt say what would fit in there.

Cost is another thing I'm not familiar with when it comes to electrics. I'm not overly concerned with cost for the most part. I would'nt mind spending about a hundred dollars maybe more.

I suppose for the most part I would just like to get into electrics. I would just like to try them, I'd also like to get away from the cost of fuel and the clean-up that goes along with it. I'm not to concerned with speed but I would like to have some performance. I would rather have longer flight times than speed.

I bought this intending to fly it on glow. In the mean time I purchased a Hangar 9 Aspire RTF (its electric powered) to fly at a local soccer field, I figured I could put the guts of it in the Wonder when I got tiered of it, Well the Aspire has'nt been such a great purchase. When I got it it was missing a canopy (they said they would send me a new one), in the meantime I put it together (exactly according to the directions). I had'nt charged the batt. yet but I plugged it in just to see what it would do, if anything. Well the motor started turning immediatly (very slowly) ,I tried to stop it with the transmitter-nothing, I tried the arming switch it came with-nothing, so I figured maybe it was because the batt was'nt fully charged .I charged the batt. I conected the batt, the motor started spinning full throttle. Tried Tx.-nothing, tried arming switch-nothing, then the speed controller starts sparking and smoking (setting-off all the smoke detectors), so I disconnected the batt and ran outside with it because I did'nt know if it would catch fire. All of this took about 5-10 sec. from the time I connected the charged batt. to the time I got it outside. I'm glad nobody was watching, I must have looked like an idiot (I prefer to sound like an idiot in here). Now they are going to send an ESC and a motor, I hope these components work.

So anyhow (back to the Wonder), I'm trying to figure out how I can make the Wonder electric without using the components from the Aspire, since I don't trust them. It has now become a quest.

Any help you could give me would be greatly appreciated.

Thanks again, Yakseeker aka: John

Status: offline 		Well if you dont mind spending a little cash that go brushless. I have my first one and i gotta tell ya. This thing makes the planes fly like there glow !!!!

You can find the Mega 1615/4 motor with controler on the internet for $139, and it comes with a free prop adapter. I have run this motor so much that if it was a can motor i would have had to buy about 3 of them buy now!! You can get KAN 950 cells for $1 a piece now ( just made an order for 96 cells. hehe ) and these are great cells. 8 cell pack only wiegh's 6 oz's. This motor combo is amazing! i have run it with gear box on a .25 size plane and on driect drive on Zagi's and HOB 1/12 war birds. Really fast on the d/d and about 6 mins motor run time.

Goto ezone and check some things out there. a bit more info onn electrics there than here.
