Formulating some ideas, need input

[tlandauer]

I am a slow guy, whether it is my boat or my build speed. So i have this hull ( H&M Intruder, 30") for two years and I always wanted to make a twin out of it despite the fact that it is on the small side and might be better served with a single motor. You can hardly use 5000 mah 4s on the sponson sides and for a twin I will place the batteries on the tunnel floor where there is ample space.
Anyway, without cutting some of the sides, one can hardly stuff in a 36xx motor, let alone with the water jacket on it. I am toying with a 3216 Fightercat Out runner or even 28xx in runner.
I have had this unusual drive ( on the starboard side) for a while, it has bearings and i believe they are Etti drives mod'ed by someone here. It is for 4mm shaft and the cable I got with them as a set is .130.
Then there is the more common drives with.187 teflon bushing.
Note the tremendous difference in their length. Which length is better?
Would 28xx in runner too small?
How would the out runners do? I bought them to replace Venom's KOS P1 outrunner, but never used them, they are Fightercat's FC3216, 2200kv,Dimension roughly is 38mm ( dia.) x 49mm (l).

Note that with the shorter drive, the shaft would be further from the tunnel due to its base plate layout, the TFL drive can be positioned closer to the floor and the inside tunnel.
Thanks in advance.
P.S.
I did do a search and some guy used the longer TFL drive and the boat rocks.

The water jacket is for Leopard 36xx motors.
I do realize that perhaps the whole idea is ridiculous, as there are hulls that can accommodate twin motors without having to resort to acrobatic skills.

Hiya Tim ,

here's a twin mean machine that was built to fall back on The Rum Runner forum with a pair of leopards in it with stingers that I've always liked. if I remember right the leopards are twin 4092's. the Stingers I think were 3" long,
.bringing the overall length of the boat to 32". I might be mistaken on it but I think the flexes were 4mm square drives.

I know I bookmark the link for a look around and see if I can't find it for you :tiohat:

Tim,

The 3126 outrunners are terrific motors. I used them in my Rivercat twin build.

My perference would be for the shorter stinger.

Thanks for the pics and the link, anytime when there is an AM hull twin, the drives always stick out that way,lol....

Thanks Ray, that's very good to know.
Happy TG.


Oops, I didn't read your advice about the shorter stinger!

id go with what ray said he has by=uilt more nice boats then most of us

[Rocstar]

I used the FCR stingers on a 32" King of Shaves I rebuilt. I cut them down as you can see. I think they are too long for this hull stock. Ran it with a pair of 3126 outrunners.

Thanks, Ron

Yes, Ray certainly is an excellent builder, very glad that he cared to give advice.!

Thank you , sir!
I def. am thinking of this as well, however, I lack the tools to do a good hacking job and i don't know what to do with the teflon bushings. I have to ask around who can do it for me.
Great pictures, I feel so sheepish to even ask questions.

Perhaps Doby knows me the best: I will just put the hull back to my garage and sleep on it for another two years!
