new skunkworks cat: twin outrunner build

[tiqueman]

Really? That sounds awesome... What size flex did you use and how deep did you drill?

Jon

I used .150 and drilled about 3/8 deep into the tail end of the stinger. Then made a bushing using 7/32 and 1/4" brass. The 1/4 inch is cut the same depth as the drilled stinger. 7/32 is as long as the 3/16 shaft. Works great.

that sheet you used for the motor mounts is sweet. should make it easy to get the motors in and out to

good thing we pulled that first sheet haha, looks alot better now..

[bea5017]

that was a complete desaster lol

[Xfactor]

1100 watts is approx equivilent to an 540 xl motor which will easilly push a 32 cat

A 540 xl is gonna pull alot more than 25 amps and can put out alot more than 1100watts and is gonna pull more like 1900 watts on a x440
not saying it wont work though.

read the post. i didnt even go with xls.. and i wasnt talking about the xls pulling 25 amps was refering to a small outrunner motor. fyi my 8xl pulls approx 80 amps * 14.8 volts = 1184 watts...... i know they can produce more power jus depends on the wind and cell count

I really hope to hear good reviews on that rudder. I started w/ almost the exact rudder on my twin Hotr. It didnt like it at all. It was very loose and very "fish taily" out of the corner, when it would go thru a complete corner. Mostly it would just spin out. I ended up w/ the one Steven sells, http://www.offshoreelectrics.com/pro...prod=ose-80085 , only using the mount and rudder and wow what a difference it made. I also think it helped a lot becasue its a bit further back.

i see you decided to go with the stingers instead of the struts what the deal

[obrien008]

any updates? you better get moving cause mines almost done

[bea5017]

hardware should be in sometime nxt week, convently the same time finals are over.... should have some progress in a week or so. once the hardware comes in ill be able to mount my motors too

[bea5017]

what props for this thing 42's 45's? do the outrunners like more pitch? blades? diameter? i no nothing about props

[bea5017]

servo layout. i want to to a pull pull setup with steel cable. anyone no and good servo arms that would work.

[j.m.]

Your standard two arm servo horn should work great. Just make sure the distance from the center pivot to your holes is EXACTLY the same on your rudder and on your servo arm.
