View Full Version : Futaba Super Candy

hi guys, I have been laying around for about 2 weeks now getting over a total knee replacement and have had time to think(dangerous !) I'll be able to get to my hobby room downstairs soon (all this free time and can't get to the boats, BUMMER! LOL) and I have been thinking of a project . I have a 21" Futaba Super Candy EL boat new in the box. I really like the looks of the boat but in the stock setup it's a dog. I also have a 700BB motor and all the parts to convert it to surface drive and 8-12 cells.
My question is will this hull handle the power of a 700BB and still be controlable? any other suggestions? what class could I run with this boat with that setup?
what is the best way to strengthen the hull and not add a lot of weight? I'm open to any and all suggestions. I gotta have something to do , this sitting around is driving me up the wall LOL.

As far as I'm concerned, a 21" mono hull is much too small for a 700 motor and 12 cells. I would definitely suggest that 6/8 cells (direct drive) would be the ticket for this size monohull.

Hey Larry, I have seen this boat run with 6 cells, I wouldn't call it a dog, I have just ordered two of the great planes 550 size motors (same as a graupner 600) but a few less winds (19 versus 22) it puts out about 165 watts that's 15 more then then a 700 8.4 plus more rpms, all this for 14 bucks,, let me at em, this seems to be a very decent motor, I like the graupner 600, I really do, but this is even cheaper (4 bucks), anyway it wouldn't hurt to try, all the mountings and hardware will fit, try this on 8 to 10 cells, it be a hoot mt 2 cents, cheers eddie

Doug, After looking a little closer I think you are right, a 700BB would be a bit much for this hull, I'll try something different.......thanks
Eddieh, I checked out the Great Planes S-600 and sorta like the idea, I think I'll give it a go, I need to make an order from tower anyway and I have everything else that I will need but the motor........thanks
evader09, thanks for the well wishes, the knee already feels better than before the operation just can't bend it very much yet. But I am able to bend it well enough to get downstairs to the hobby room so I'm starting on my projects tomorrow..........thanks

Larry, My motors come today, yeehaa, the more I see the wattage and what some very knowledgeable guys put up about rpm per volt, this motor's a steal, that is until everybody finds out about it (remember the aluminum solder!! LOL) anyway great planes also makes a very decent tranny problem is it only comes 3 to 1 or worse, but..... if you take a standard pinion from the car guys, A larger sized one, you can drop this down to a 1 to 1.72 very nice, I have this in a fairly heavy mahogony runabout and on 6 cells it's planing down to the last 2 inches of the hull all ball bearings come included, it has a 4mm output shaft, and my local hobby shop carries them for 16 buckaroos,,,,, another 4 bucks for the pinion my 2 cents. cheers eddie
