The new guy...

Norwest, thanks for the tips! As for the trim tabs, they are spaced about 1/16 up off the back edge of the transom. As for prop angle, i would say prop is currently down a degree or 2. As for prop, keep in mind this motor/prop combo is running thru a 1.5:1 gear box still...and can i say it gets on plane with that 3 blade like a bobber popping out of the water...LOL and the temps stated were after about 15 min of runtime, with no water jacket.... the jacket is on the short list of items i need to get...LOL i never had any issues running my rc car brushless these temps either... esc after that 15 min is barely even warm.

I will get a vid of how well it runs sometime soon....LOL next time i am out with it...

[Norwest]

You have it well in hand! I'll be reading and won't post!

question for you norwest (or anyone who cares to answer for that matter), on the props, i have read a lot of different ideas on diameter vs pitch....according to the calc here, it looks like the 39mm 1.6 prop you mentioned would push to roughly 33mph, factoring 80% efficiency, and 25% slip... would that prop actually have less load on the motor, considering the 52mm 1.4p prop is good for (again, theoretically, according to the calc) 26mph? also, wouldnt (due to the 1.5:1 gearbox) a smaller prop be more prone to cavitate due to increased torque, or am i nuts on that one? oh yeah...boat is not all that light either... need to weigh it at some point... im sure that has an effect on load and prop size....

i dont really know the effect on the loads in play here (im a lowly john deere mechanic, not a fluid dynamics scientist...LOL)

also, is there any operational differences between a silicone water jacket and an aluminium one, or is it just for looks?

all i can do is ask...LOL there are many here (probably all here...) who know more about FE boating than i do... im here to learn!!!

[bogieboy]

And as promised... some vids....

[Norwest]

max speed for that boat. Your work has paid off!

[bogieboy]

I guess its not too shabby for a $150 investment, all parts included...LOL would a set of turn fins be worthwile to prevent the spin?

[Norwest]

Yes it would.

[bogieboy]

So.... few big things in store... hoping to test them out tomorrow.... switching to full watercooling, upgrading the underpowered 80a air cooled esc to a 150a flycolor, and added a silicone waterjacket to the motor... now i have the ability to run 6s as well... hehe run 2 3s packs in series... also got the turn fins a few weeks ago but havent been able to get out to the canal yet...

I see a lot of trouble abound with cooling and connectors not up tight as they can touch each other real easy.

I see a lot of trouble abound with cooling and connectors not up tight as they can touch each other real easy. i'LL LEAVE ON THAT NOTE AS I MOST LIKELY WILL t YOU OFF AND NOT INTENDED TO DO SO.

Norwest, not one thing you have said has teed me off, i am sorry if you felt that way in some of my responses... i come from an rc carpet racing backgroud, and know jack squat about rc boats other than i use the same transmitter as my car...LOL i ask questions to learn...

i know i need to re shrink those connectors, they arent quite the same as what was on the original esc, i was planning on doing that first thing tomorrow...

What problems do you see with the cooling? Are my lines too long? Or is that silicone motor sleeve going to give me greif? Lines are run prop wash-motor rear-motor front (pinion/highside)-esc-out the back... Or is a prop wash pickup not ideal? I am still considering converting to a stinger and a rudder...moneys tight right now....LOL

[Norwest]

Crap I hit the wrong button and erased the whole reply! Cooling lines are good and inside diameter of hose is great. Water pickup or prop wash as you have done should be watched to see if water comes out the exit. Let me reread your post again and i'll get back to you, promise.

[Norwest]

Ok, just wrap tape around the connectors. Now as far as change of rudder and etc, let what you have and see how things go.

[Norwest]

Must be tired, can't even spell, lol!

[Norwest]

I hit the wrong key again.

[bogieboy]

Norwest, its all good!!!LOL normally i would tape those small gaps but i think i am out of tape right now...LOL i know i have heatshrink left yet... and 10-4 on watching the cooling output!
