Default SIG Somethin Extra to Electric

Has anyone converted (built from scratch) a SIG Somethin Extra to electric and if so what did you use. I am just gathering info at this time since I am still doing a second kit and was seriusloy considering electric for this.

I would like nice power for good vertical and other high alpha maneuvers

Im doing a tower uproar which is needs about the same power, im planning on using a AXI 28/26/12 with a thunder power 3S2P 2100 pack.

Just a thought for yours too

Wellllll... The SE is a bit heavier than an Uproar, if I remember correctly. 5 pounds as opposed to the 3.5 pounds for your Uproar.

If you could build it REALLY light, the SE would fly on the same power system, as they are very similar planes in form and function. Otherwise, you'll need More Power(tm).

Instead of a 3S Lipoly, I'd probably suggest a minimum of 4S.

I wonder... There have been several SE conversion projects in the past, but have there been any in recent memory with modern LiPoly packs? The ones I remember all had 16 NiCds crammed up under the hood.

Thanks to everyone so far. I already have the kit completed, with the exception of the covering on the fuse and did build it light (CA and Gorilla glue).

I am not much into 3D stuff, more pattern and IMAC but I thought it would be fun to do this kit to mess around with 3D and high alpha stuff in electric since I was at a fun fly this past weekend and saw one that was converted. Unfortunatley I could not get all the info from this person since I was the freq officer and did not have a lot of time to ask the right questions.

Power is good (isn't is always) and I always want a reserve of power for those times that I dumb thumb it and need to power out of it. My normal flying is usually around 1/2 throttle on glow power.

True, just looked them up, a nitro uproar (from towers specs) is suposed to come in at 3.5-4lbs and a SSE is suposed to come in at 5-5.5. Hmmmm...

But i shouldnt be answering to many questions either tho, im a nubie in the brushless world!

Try a Plettenberg Orbit 25-16, 5s2p lipos (4000) APC 14x7E, pulls 33 amps. I'm waiting for an APC 15x8E.

Default RE: SIG Somethin Extra to Electric

Hey all, just (well not just it's been sitting built for over a year ) finished my Somethin Extra, got my electronics for it, but I'm having a bit of an issue figuring out how to mount the batteries. I've got 2x2s Kokam 3200s (they're driving an AXI 4120/14 FWIW), and for balance the lipos need to be in the fuel tank area. I'm looking for advice about mounting them. I'm tempted to use foam rubber to "wedge" them in, but I have serious doubts about them staying put, as well as reservations about that insulating them.

I'm looking for any ideas, or especially successful methods for mounting them.

Thanks.

I use a single 4S4P-8000 pack in my Somethin’Extra and the pack sits on top of the wing tube and a lite ply plate up near the firewall. You may be able to do something similar by taping the packs together. Check out my web site for pictures.
