which motor?
recently got this plane: [link=http://www.google.com/products/catalog?q=advance+25e&hl=en&prmd=imvnsfd&bav=on.2,or.r_gc.r_pw.,cf.osb&biw=1280&bih=654&um=1&ie=UTF-8&tbm=shop&cid=18427966544809214872&sa=X&ei=57-XTrvfB-jaiQKH9qzXDQ&ved=0CFgQ8wIwAA]advance 25e[/link]
i want to power it with either this [link=http://www.hobbypartz.com/96m604-bigfoot32-3520-770kv.html]tacon motor[/link] or this [link=http://www.hobbypartz.com/86mc304-3520-800kv.html]exceed rocket motor[/link]
price aside is there any reason to get the tacon?

RE: which motor?
The Tacon has a lower max wattage rating than the Exceed 32, but the rating is still far in excess of what that plane needs.
Both motors WILL work, but the Tacon will be more efficient as you'll be able to keep current draw in the sweet spot of the usage curve.
I would use the Tacon with a 3600-4000 4S Pack and a prop in the 12x6 range ... e.g. 11x6 - 12x7
I fly several heavier planes with the Monster Power .25 that has specs almost identical to the Tacon, using a 12x7 prop and the same size packs.
The planes hover just fine at 80-80% throttle and are quite fast in flight.
Use full throttle sparingly, as your plane will have PLENTY of power.
You should be seeing flight times in excess of 10 minutes easily.
I've clocked 16 minutes of mixed aerobatic flying on a 4000mAh pack with power for landings still available. I returned about 3300mA to the pack.

RE: which motor?
I have an Advance, but went with the E-Flight 32 motor and 4 cell. I recently put a Tacon in a Butterfly, though, and I think for the money if I were to have the Advance to do over again I'd use the Tacon 32 you linked to.
You will likely find you have to have the battery pack all the way back hanging off the tray to get CG right, but it seems to be a neat little plane. Sheeting or covering the top of the cheeks makes it look more finished.

RE: which motor?
The plan is to run 4s. Went with the tacon cause the exceed is 20 g heavier and I read about cg issues with the heavier motors. Also the exceed seemed like overkill. I got it all mounted and am just waiting for my new tx and rx to come in.
I will be starting with a 10 x 7. An 11 inch prop will just clear the ground.
Does anyone know what kind of timing should be on the motor? I have the esc up to 22.5 degrees of timing. 26.25 would be the next and final step on my esc.
I would like to cover the cheeks somehow because it would improve the looks for sure.

RE: which motor?
Take a 10x8 with you and check the amperage with a watt meter. 10x7 on a 770kv 4s set-up might be a little small. I have a 890kv Scorpion and 10x7 is about as small as I can go on a Pulse 25.

I covered the cheeks on mine. It does improve the looks IMHO.

you converted to tail dragger? Do i need to get bigger wheels? Seems like much bigger then 10 x X would give little clearance

RE: which motor?
Yeah, I did convert to tail dragger and I used bigger wheels.
I wouldn't recommend the tail dragger conversion for this, though. I thought it would be strong enough with a piece of ply epoxied to the sheeting just ahead of the wing, and nylon bolts run to blind nuts on the ply battery tray, but it was easy to knock off that chunk of the fuse until I installed some balsa spacers between the bottom sheeting and battery tray, and replaced the first couple inches of soft balsa sheeting with ply.
Solid now and flies nice, though, but I'd buy one of the similar tail dragger arfs if I were to do it over again.
