All the bearings I make are offset with larger holes than the above,(old picture). Slots vs holes its what ever you prefer to do, I have never had issues going either way and believe there is no "best" way to do them the only real performance gain that would never be seen would be to reduce the bearing surface ride area a ton-that would also lead to premature bearing failure.
A diagonal cut slot would end up pushing the grease up and away from the stub toward the engine (or out the back end) basically running itself dry faster than a hole or slot cut straight (side to side) that would hold the grease in the bearing longer, think drill bit but if greased and fit properly I still dont see a bearing failure happening as I dont think it would clear out before the tank ran dry.

well this is all good info once again.

im pretty sure somewhere in the back of my mind i knew that i was going to have to prime it all first. its just not what i wanted to hear

i like the idea of running a 7/32 tube, im not sure why but i do.

for this hull ill probably do a 1/4inch tube.

andybenton

poor pro .15s front bearings gave out on me today all at once in the stampede, slinging fuel out from around the flywheel. lol

looks like this hull will get a chance to hang out for a while after it comes to me

toyotatruckin

Thats ok,gives time to get the other stuff done an bought for it

advanced builder

Some say to replace those bearings yearly, 2 times in down south weather ,where you use more often .the rear ones go first most of the time. turns that tuning pipe & header nasty color LOL

andybenton

its never had a set, 3 years old. starting running a little sloppy a few weeks ago. then today i brought it back around to me and looked at the crank since the inside of my body was covered with nitro, and i noticed the front bearing was done. the seal was completely eaten away.

pressure tested it and it leaks like a stuck pig ha ha.

andybenton

hey TT can you post some pics of the cowl for that hull?

toyotatruckin

Here ya go-and one youll be getting (the little one of course lol)

andybenton

take your time XD avoiding bed as of the moment.

still waiting to hear from pay pal
getting anxious lol

toyotatruckin

setting up a new account takes a little time

andybenton

so ive noticed... but it doesnt look or seem that the hull is going anywhere any time soon.

who knows buy the time my pay pal account is ready to i may enough money to get the motor and the hull all in one shot lol.


so you say the hulls do have rails in them allready? and is that a home made motor mount youve got on yours? ive made a few out of plate aluminum, or angle aluminum with rubber isolators.

wasnt a fan of the angle with isolaters. but my buddies loved em

toyotatruckin

yes the rails are in it, and yes the mounts are home made, hardwood blocks glassed in and aluminum

andybenton

thought so.

ive got some 1 inch birch plywood leftover in the garage and some flat aluminum stock still. should be able to whip up a motor mount in no time

malicent

Yota whens that boat to the right getting done lol. Get this .18 in the water man!!

toyotatruckin

hey man, its on the list, right after shop clean-up

andybenton

wonder what prop that go motor will like on that hull

toyotatruckin

Im starting with a p215 and go from there

andybenton

what a coincidence. i happen to be sitting right next to one still on my balancer as we speek. (started and got lazy!) lol

can any one give me an idea of how nitro resistant base coat, clear coat paint systems. im pretty sure its pretty fuel resistant. maybe up to like 45% but i understand with prolonged exposer it wont stand up very well

toyotatruckin

OK radio box finished and drop in ready, I like stand alone boxes when I can-meaning unhook control rods and pull it if I want

The nest before I got it all in


And the sardine's all stuffed in lol



1 standard size servo, 1 mini servo, RX, switch, regulator,and 2s 800mah lipo

Oh before I get asked I make the switches from castle bullet connectors and wet noodle wire soldered on to a piece of circuit board that the correct connectors then get soldered to drill two holes in radio box to fit the switch and epoxy it in no possible way for it to ever leak and it cant really ever fail only downfall to it is the the post OR the wire will remain hot which reminds me I need to add a piece of shrink wrap to the post lol

advanced builder

Cool , I am with you, I think. Never played with the lipo stuff I like the size . along with the creativity ,great job

andybenton

i like the idea. where did you get the regulator?

ive got some small lipos that i wanted to use. otherwise ill be stuck with good ol AAs

toyotatruckin

Heads up RC is where I got mine, battery to. I took up electric flying for the last year before jumping back into boating and learned all kinds of interesting stuff that converts over to boat use. It was suggested to me to try A123 cells instead of lipo's so I could loose the regulator (a123's are 3.3vper cell) but the regulator allows me to dump just about any voltage pack in the box and still come out a flat 6v(or 5v with the change of a jumper) so if I couldnt fit the 800mah 2s in it the store has some nice little thumb size 3s 360's that will fit anyplace here is the heads up link hes good with shipping cheap on price just deals in plane goodies though

andybenton

awsome. ive got like 10 or 15 quarter sized lipos (literally the size of a us quarter)

all of them ar 800-900 mah even got one or two 650s.

but im thinking of using the 900 mah and making a series plug for them so i dont have to use a balance plug on them scince they are all single cells.
could even do 2s-2p in the 900 which would make them last quite a while.

cant wait to get the motor and hull lol.

what did you make your radio box out of??? birch ply?

toyotatruckin

regular old aircraft ply from the hobby shop 1/8 thick

andybenton

ok. i guess its sealed with epoxy? or did you clear coat it?

and finally how do you plan on sealing it??

i know im full of questions haha
