traxxas villan build

[20psinow]

and i did trim the top of the transom do have a pic yet but all the pic were of when the glass was wet will get some more up tonight, i think it turnd out ok but this is the first time i ever played around with fiber glass

TOO MUCH EPOXY!!!!

You didn't use paper towels to soak up the excess, now you have a bumpy surface. If you sand it you won't be able to tell when you get to the fiberglass and you risk damaging it; i.e. sacrificing the strength.

j.m. i know its to much epoxy but its hard to tell from the pics it not all that thick it did build up in the V but i was going to sand/cut very little out, but now that i look at them pics it looks that way, and no i did not use the paper towels to soak up excess but i thought id add some weight to her to keep her in the water, if you seen the lake well it has huge chop to it.. and for sanding to the glass well i am going to have to be smart about what im doing but as long as i dont start going nuts i should be good, i guess i will live and learn on this one but to tell you the truth i did not even think about the paper towels..

well got the mount epoxyd in the hull its 1/16th in. off on one side and i cant seem to make it even so thats were it sits, also did a quick getto fab for a floor stand and hope to get the drive line in this weekend at a 2* angle..




and yes there is a build up of epoxy in the v and now there is a bigger build up from the mound but it will all go away soon!

[j.m.]

1/16 shouldn't be too much of a deal...

Lookin good!! Drill a hole the same size as the outside of your stuffing tube. I'd say give it around 1/4" from the bottom of the hole to the bottom of the hull. You can find out exactly what distance you need by drawing everyhing out on a piece of paper. Lookin good!

Any progress?

[20psinow]

ahh no i have so much going on, just had a guy leave work and need to find a replacment for him, i had a little project for the car that is sill in progress but cant move on that yet no parts, and was gonna drill my hole for the stuffing tube (3/16) right now and cut some wood up for it and mount the tube in. the mount is all done and now i need to sand down the over flow from the epoxy, but no progress yet i will post some pics tonight of the stuffing tube and try to get maybe 2-3* on it.

[20psinow]

well i think this is a good angle on the shaft, now every thing is not set in place its all just mocked up for right now, still need to cut the shaft down and found out i need to notch the motor shaft flat because the flat spot dose not come out to the hole for the flex, and i have a longer pice of the stuffing tube dont know if that would be worth using and the stuffing tube is set at 2.75" out of the back of the transom right now 3" just looks to far out there but i dont know! any advice would be sweet befor i epoxy stuff in..

[20psinow]

and i need new motor mount bolts!! i dont have the right size...

[j.m.]

That's looking pretty sweet, but bring the prop forward a little and point the motor down as far as it will go. The shaft should move up and forward a little, which will also reduce the angle slightly; then it'll be perfect.

Don't forget about making a forward support for the shaft. You dont need a long stuffing tube, that will only create excess drag. Just make sure the shaft cant wiggle around. (I'll bet it moves side-to-side pretty easily as it is now)

Jon

[20psinow]

yeah right now it move side to side but still need to find the angle and make some mount for the shaft out of oke. i still have some of the stuffting tube i can cut off and move to the front of the shaft to support it.

and also how far should the dog drive of the shaft stick out of the stuffing tube? my guess is 3
" but not sure and i can move the motor down one more noch but what about the angle on the flex? not sure how far is to far..

[j.m.]

It doesn't look to be bending too far... I would think it could bend to abou1 15* and be fine.

VERY clean Villain... You'll have to do something nice for the battery mounts.

Jon

[20psinow]

yeah that will be some time soon when i get some guts in her.. i just hope she runs great as i hope when shes done, and from what i have seen others do i just dont think they took the time to make it look good.. well tomarrow i will try one noch down and see where she sit on the flex and then from there i will make my mount for the shaft, might have to stan it and epoxy over to seal it also if i like the angle on the shaft i will epoxy that in to..

[20psinow]

well i did change the angle of the shaft by lifting the back of the mount about .25" up and down play, if you lower the front to the lowest hole the shaft hits the bottom of the hull.. the oke idea did not work so made a getto mount for now to mock up (makeing another one that fits the hull better and not as wide) so now the stuffing tube is 2.50" from the back of the transom and going to let the dog for the prop hang .25" out of the stuffing tube..

[j.m.]

Looking good!

Did you get a thrust bearing? It goes between the coupler and the motor mount so that the force from the prop isn't on the back bearing of the motor (BAD).

I would try and make a simple triangle shaped support for the shaft out of the left over ply. Make an isosceles triangle about .25" taller than your block, put a hole in the top of it with about 1/8" of wood all around. This hole should fit the brass tube tightly.

Now angle the bottom of the triangle so it fits nicely in the center of the vee. You can slide the support for and aft to get the angle correct without having to minutely adjust the height.

You don't want the shaft only supported by epoxy on top of the block because epoxy is strong, but it's only an adhesive. It should not be used as a structural agent.
