I would like to use waterproof aileron & flaps servos in my FC with floats, can someone tell me whether or not this Traxxas waterproof servo appears to be adequate: http://www.servodatabase.com/servo/traxxas/2065

Thank you!

hmmm might work.. the thing is, they are on the heavy side for a servo of that size. plus they are kinda slow servos... (thats a personal opinion... i like fast servos.) but really it is a slow servo comparably to say, an hs-55 or HXT-900. plus why do you want water proof servos? you dont need them at all. I just covered over the servos with some tape. that works, and keeps em from too much harm.

Should work. I agree its a little on the slow side, but the fun cub isnt exactly a quick reflexes plane anyway, right? The price makes will cringe though... IMO , its easy enough to waterproof a standard servo with some silicon and grease....

+1

But in all seriousness, dont worry at all about waterproofing the servos. they dont care. its not like they are getting dunked and held under water. they are just getting water spray.. they will be fine. but if the insurance of water proof servos makes you feel better. just get some silicon caulk and run it around the servo after its glued in (making sure not to get it near the control arm! ). then just slap some packing tape over the servos and BAM you got your self some extremely water resistant servos. dont go and spend all that extra money on those traxxas servos. just do it your self on some HS-55's or HXT-900's or whatever you plan on using.
Good luck!!

With a cg slightly forward or equal to 70 mm I "feel" like it is a little too nose heavy. Can some of you chip in your experiences with moving back some and how much?

Hitec offered some waterproof servos (2 different ones) ... Actually work while completely immersed

http://www.robotshop.com/blog/waterp...h-rejoice-1001

Ace also offers one
http://www3.towerhobbies.com/cgi-bin...&I=LXBZBX&P=FR

As does Turnigy
http://compare.ebay.com/like/1407810...Types&var=sbar

However, I would suggest purchasing a set of Gary's servo covers for the Fun Cub, combined with some conventional (HS-55 or equiv) servos, perhaps with some silicone applied to the case seams if you feel it is necessary.

I'm fairly new to assembling foam models. I'm putting a FC together with floats. What is the best method to mount the servos in the wing, double sided tape (which brand), silicone or?

Thank you!

Hi Itsme,

You are on the right track - tape around the servo and then hot glue it in the wing. Alcohol will debond the hot glue if you ever need to remove and replace it. Tape removes from the servo.

Cheers!

Gary,

Sorry but I don't understand what you mean by "tape around the servo", please explain?

Thank you!

wrap the servo in tape, then put the glue on the tape, which is on the servo, then just stick the servo in.

Speaking of hot melt glue, I have always been conservative and used low temp hot melt glue (I know, low temp hot melt...it's like jumbo shrimp; doesn't sound right) on Elapor (and Depron)

Is high tempo/standard hot melt OK for Elapor ?

Also, for those who use CA to mount servos, use caution. You would be surprised where too much (thin) CA can go ... I've heard of servo cases being glued together and glue getting into gears and servo bearings/bushings....

Wow, thanks for the clear explanation! Is the tape you use packing tape?

Nope just some good sticky painters tape will do. and make sure to wrap around the servos a few times.
