Ooooh-weee T-Shane, you sho' is hard on them boats! Well, nothing a little bailing wire and duct tape can't fix. Wonder what the I.D. of that pretty purple strut is? Looks to be a good candidate.

Nickster, the Octura x435 is the largest in their line for a 1/8" shaft. Those larger are for a 3/16" shaft. And I think if you try the 35mm version you'll likely cook something, so do it briefly and check temps! You might want to look into a bearing strut for more speed.

Bailing wire ? lol

Gone and got me that there purdy purple set ! shame its gonna be 7-25 days ! I might just be quiet on here till I manage to break something else !

the site seems to have mini bearings too but no bloody dimensions !

gutted - no boat ! Hmmmm - maybe I gotta go swimming....rescue that one I lost .... mmmmm

mini bearings -

Now that sounds like a good idea - sounds like you could use the spare parts!

Rake

Too right but I aint gettin in that pond without the man and boat !

sdz - look what I found....

I measured the OD of the rear end of the strut to be 7.2 mm so this might be the one. Only thing is that the etti strut uses 2 bearings, 1 front 1 rear of strut. For this to work I can only use 1.

What do you think ?

I'm still new to this photo thing

Rake: If you can bore the strut out to 1/4", then you're home free. What you use is a flanged bearing at the rear and you'll cement a regular bearing inside at where the rear of the bushing is right now. I've got a supplier for both. Since you will be getting that purple kit, you'll have another to experiment with. And the one in the kit might have a larger hole - you'll have to wait and see.

msmail: Clean looking job there! And you say it seals well? That's a lot easier than taping it all up, and you can get inside faster if it's smoking! If you're flipping the boat a lot, move the battery all the way to the left side and it will settle down. The motor torque is flipping it whenever it gets airborne. Nice job.

Sundogz: Thanks for the tip on battery placement. The octura 430 prop ,larger than stock, put the boat on plane now, incresed speed  probably 15 mph. Have over 30 runs. I have  been lubing the cable with WD 40, water displacing 40 after every run which NASA developed, never taking the cable out. Still no water leaks. After I run motor and esc are cool and battery warm. Ordered premium 25C batteries can't wait to try them.

sundogz

You're quite welcome. Any increase in 'C' rating will result in noticeably faster speed in this boat. It will handle a 32mm prop but watch temps. I use WD40 for many things around here - it's good stuff. Never heard of using it in a stuffing tube - usually want grease to help keep out water intrusion, but I suppose if even air can't leak out, then water can't get in. Good to know.

Rake

Small bolt number 1 has been recovered from the depths and the experience was horrible.
Dead rats in the pond and the water was over head height. Will post pics later. Hull split half way along.
Due safety was used. Had a dry suit on and was tethered by a climbing rope. Not recommended for the feint hearted

sundogz

Bravo!! Sounds like it was a horrifying experience. [:'(] Reason enough for a shot of tequila. Yes, post pics please. Do you suppose after a proper amount of drying time that anything will survive such a soaking? Jolly good job!

YUCK!!!!!!

Whatcha guys think of this?

Can't find much info on it - how many cells can it handle? Top amp draw (what esc recommended?), idle amp draw (resistance?), etc. You would want to run it on 2S - rpm's are too high for 3S. Could be a contender - may handle the larger props better. I say buy it and try it!

Rake

I have no idea what will be good after this length of time but will wash and dry and see.
If the hull motor and servo make it then I may have two boats in a while.

I went in with a broom pole and at the last moment before giving up I found it and got it between my feet and out. At the very least I'll have a new rudder. The hull fix will be a challenge. Pics later will reveal .


Bass that looks like a nice motor. Time for another coupler ? What cells would you use ?

msmail715

I have block sanded the sponson bottom, sides, and ends for sharp corners also the entire hull. Do you think this will help with speed? 35 plus runs still no water. I'm lucky to have a 1/2 + acre pond but I have a cold and it's raining or I would run in the rain. I also run nitro boats but the field equipment and maintenance are a killer.

sundogz

Crisp edges and finely sanded wetted surfaces are nothing to sniff at. You can observe a measurable increase of speed with this special attention to detail. I'm hoping someone obtains a small gps with which to record actual speeds of these micro rockets.

Rake, you might as well tear it down completely. I have a feeling you'll be needing more parts sometime soon!

Maybe in due time Rake.

I sent you the info needed for pay pal by PM in case you missed it.

Rake

You may be right sdz but may try for two bolts, one 2s one 4s. All depends on the hull repair. Still intend to post the pics later.

Bass, will sort payment today.

Two Small Bolts are better than one! Give you someone to race against!

Set one up 3S with the Tacon Motor. Or try that Tenshock motor on 3S and hang on to your pants!

Rake

Fixer ?

sundogz

Well you can swap hatches and have one pretty boat, and one to scare the onlookers with. Gotta say, when you crash 'em you do a thorough job. Better buy some more epoxy....

Rake

Your not wrong there sdz this is the most effective crash yet. The motor is good as is the drive and hardware. Servo is water proof and I have a spare Rx and esc so if I manage a hull fix then two bolts are a possibility. Lipos not yet tested. Got loads of resin left. Will get to it next week.

sundogz

Good to hear about the motor and the servo. Maybe now is a good time to look into putting bearings in a strut? It will need to be drilled out to a tight 1/4". Something to consider anyways.

Rake

Not a bad idea at all. Do you think that the rear bearing needs to be flanged or will a regular suffice ?
I have 2 coming already but they are unflanged.

I am also considering separating the top and bottom halves of the smashed hull to effect abetted repair by classing the inside up good and strong but am as yet undecided.

sundogz

You could get by with a non flanged bearing by cementing it in place. That's a good idea to open the hull completely to gain access for repairs. But putting it back together would be a challenge!
