Maritimo build

well so far it was two solder joints that failed both i did and the other ed hughey soldered slipped from the coupler due to not being tight eneph. and youd think id have learned by now!!

Maybe you can fabricate some type of prop saver?

Ever since I went to the red permanant loctite, I have not had a single drive fail. I have busted some wires, but unrelated to joining wire to stub. I would bet if you went to the loctite and threw out all that solder crap, you would be a happier boater.

Slipped from the coupler??? Dude, mega

Are you just losing them from the left? If so, maybe check that coupler.

Dang, dude that sucks. hope you had a fun time while she was running!

waiting for vid....

well ran her this morni'n' and chanced it with one of the shafts i soldered sense the one ed hughey did fleww out yesterday.. and you guessed it ... lost another. (axspensive weekend) . she ran .8 mph clower and the batteries were preheated to 120 deg. i dont get it?? ill send out the two remaining shafts to ed and try this again.. dont really have a choice, got to do this!!ill get another set or at least a r/ hand to match the lost one..im down loading the vid. and will post asap.heres the pics requested:

[wolf IV]

Tomorrow!! Im gonna get my batteries real nice and hot in the oven (just kidding).. Ill warm them up 10 more degrees and see if it will give me some increase in speed. Also the props that ill use havent seen water yet , so thet could work better than the initial set i hit 66.7 mph w/..ill foresure post something tomorrow along w/ pics of the props for you guys!

[domwilson]

Sorry to hear about this. Good luck in getting everything resolved.

[wolf IV]

good luck with motor set up, these props sound pretty soffistikated... Need to see em.

So wolf, do you have a target speed or just faster than the last run? I should be able to hit 60, but am not in a hurry as i know things can break at that speed.

What were your temps at 64?

Must see props....

target speed is 70mph...

[wolf IV]

Alright guys.. I took her out with 477's cut down to 442's .2'' more pitch / backcut &detounged.i could tell right away she wasnt right.. I did a few passes and hit 61 or 62 or something..? As i was bringing her in she was tiilting and i could hear one motor reving w/out a load ( dejavu)... Im so sorry to all ! I lost the entire left drive drive. I KNOW WHAT HAPPENED AND IM KICKING MYSELF IN THE BUTT FOR IT!! last night as i was installing the drives my 1.5mm hardened handle allen tip broke. it was the last of 5 of them i keep on hand. so i used a regular allen and tightened all the coupling set screws as tight as i could . the problem is ive never had to use a normal allen to do this... it wasnt tight eneph those shafts could have been slipping in this case, causing the decreese in speed. i noticed a bit of a cavitation but thats from the cuts.. ill have to get andi to do me up another prop to match and retest.. tomorrow ill try again with an old shaft i soldered and egnegs 442's detounged and hope the shaft holds for a run (for the props sake).. ive got 2 old shafts so ill take the chance. then ill send them out to ed hughey to braze them ...im not gonna post anything tonight ( kinda boring at 60 mph) but will get a successful run tomorrow on footage along with pics of the props. i didnt get pics yet as i went through 7 batteries flying my t-28 @ the local park to take a break from miss timo..

[domwilson]

Do you have those pics of the prop? How did she run?

[wolf IV]

ill take some tomorrow for you. heres the shafts.

[domwilson]

i had andi brown do me a set of x447's cut to 442;s back cut and detounged w/ .2" more pitch. this is what ill test tomorrow. the other two sets are egnegs 442;s detounged wich is what i hit 66.7 mph with but lost one on the shaft breakage. the others are abc h-1616 /3 blades maybe chuck will chime in as i forgot what he did to these :)..

Do you have any pics of the backcut props?

[wolf IV]

OK Wolf , What are these props you are trying , You have got me very interested. I'm still waiting on my new cell / props for the Simrad. So looks like I'll be chasing your speed times. If you do a vid put the camera on a side angle , will give us a better idea on how fast it really is. Good luck dude . BONEWAR
