any one got a freeair tom 740 mm (29") wing ?


hello there people as the title says anyone got one ? i'v got a spare hacker b20-12L 4630 kv inrunner motor that needs to be used, i think it could make the wing do 80+ mph on a 4.75 prop and 30 amp esc using 1800 mah 3 cell lipo, if any one does have one let me know your specs please, this motor used to be in a voodo pylon racer that used to do almost 200 mph before it tasted the dirt, look up the voodo on youtube man there fast, any help for uses for this motor would be helpfull i want to put it in a wing for speed runs i look forward to all suggestions,
thank you
Steve G
can someone reply please, any suggestions are welcome

here's a pic of the wing


here's a picture of the wing in question and a link to the web page ( http://www.freeair.cz/freeairen/inde...mart&Itemid=53 ) think it would fly nice strengthened up with a high kv motor and small prop, plane size is

740 wing span

370 length

215-300 g flying weight

60 to 80 watt motor is recommended

2-3x LiPo,

but like i said I'm gonna stick the hacker B20-12L 4630 KV inrunner on it & a 4.75 x 4.75 apc prop should be ballistic

if anyone has any better ideas for this motor (hacker B20-12L 4630 KV inrunner) maybe a small pyon racer, would rather stick it on a small wing, have never tried a pylon racer think i might like something that could hit the 120 mph mark I'm not sure how fast this motor would make something go using a4.75x4.75 prop, 40 amp esc,30-40c 1800 mah lipo, ANY IDEAS ARE WELCOME PLEASE HELP I'VE JUST GOT TO MANY IDEAS IN ME HEAD, tis a nice motor

My initial thought is that a motor of that high KV would be way too impractical to run direct drive, especially on 3 cell. But I have no experience with that motor so I can't say for sure.
