Seagull models Decathalon .40 conversion?

Was looking around this morning and saw this ARF on horizon's website for $129.00, and was wondering if this could be a good conversion project. Anybody have one of these, and would it convert without too much work?

I have the Phoneix Decathalon with power 46 on 4s flys great. You will know or learn what the rudder is for. Did put a hatch on bottom for the battery.

I have been flying the Seagull Decathlon 40-size. Wingspan is about 66 inches, so it has a lot of wing. It is a bit difficult to get into the cockpit behind the firewall. But if you have the patience, you can hink around, install an electric, and build a battery box in the front of the cockpit.

I fly it with a Power 46 from leadershobby (2200 watts), with 4S for sport, or 6S for much better power. It would probably be better to put a Power 60 (2200 watts) in it with about 380kv, and 6S 5,000 mAh.

It takes off like a Piper Cub, and lands a bit faster than a Cub. No bad flying habits, but is tough to do knife edges (high wing thing).

I think that this Seagull ARF is a good deal.

Thanks, good to hear a reply on this as I already bought it and am going with the power .60 on two 2600 5s packs. The extra 3 oz of motor weight over the .46, and the smaller packs that I already have should help with getting the cg needed. I am making sure of the needed mods to the fiewall area are correct before I wreck this thing cutting wrong.This is a little tougher than I thought it would be placing the parts were they need to be and trying to keep it on the cg machine! I haven't got the motor yet so I've got a 13 oz lead weight hanging in there and tapeing the batts on top to check it. Am thinking a tray on either side for the packs and build box/trays for them. Thinking hatch, but not sure how to approach that, almost easier to remove the cowl for changes and slide them in from the front with stops on the trays at cg place. Easier to beef up the firewall than f-2 and3?

I have the 66" Seagull Decathlon. I put a leadershobby Power 46 (2,000 watts in it). 4S will sport fly it, but the plane wants 6S power. Try any electric that will put out 10 pounds of thrust. The plane flies well, but the Decathlon does not have a symmetrical roll, as it is a high wing.

Takes off like a Piper Cub, and lands quite a bit faster. Will carry 10,000 mAh of 4S batteries.
