1st Build DeltaForce 29 mono

[monoman]

My first build and my first explosion these photo's were taken after I removed the confetti the capacitor's produced

[Boatman]

what KV motor? Is that a 45mm carbon prop?? might want to move coupler further away from motor so you dont have quite as much cable un-tubed. Great looking boat and build though. Thank goodness for warranty.

Fiegao 7xl 2382kv and a Pranther S220 43.7mm 2.6" pitch

So...even the ETTI's will burn.

[Jesse J]

what batteries were you using? how were you driiving? bashing or racing? - all good things to know for the rest of us with Ettis.
Thanks,
J

Batteries are Poly RC 6000mah 2 x 7.4 in series, I was just cruising up and down the river about 3/4 throttle and slowly bringing it upto full but I couldn't hold it at full throttle for any longer than a second or two because it was threating to become airbourne, and it did fly at one point

[detox]

A smaller and low pitch prop (under40mm) may have helped prevent that fire. Better yet a cooler 8xl or even cooler 9xl would work safer I think.

[Jesse J]

Holy macaroni, I bet she was cruisin before meltdown. Yes chill the motor, and/or the prop. I bet you were cookin with >200 amps! I wonder how 3/4 throttle might have added fuel to the fire...

[monoman]

Yep it was absolutely booting before the magic blue smoke appeared. One thing though two caps exploded but one still held and I was able to drive the boat back to me as if nothing was wrong ( except the 2 loud bangs which came from the boat).
Can't believe I didn't any video

[Jesse J]

so is the ESC ok? can you just replace the cap board or is the whole shebang toast?

[Boatman]

honestly, I am sick of hearing about the half to 3/4 throttle thing. YES, you are building and specking to full throttle but honestly if they werent meant to run at 3/4 throttle then why are we paying so much for these when we could just put a servo operated switch for on/off. I wish whoever started that crap would not have. I run my boats 3/4 throttle all the time and even those who say otherwise likely run theirs that way too. Its a fact you have to slow down and speed up.

[Jesse J]

why does this get you so agitated? what's the problem with discussing possible variables? Please share your data to dispel this "myth". I was told by a valid source that driving around at 1/2 - 3/4 throttle and then punching it is a good way to blow a FET... If you have good data, lets see it. No reason to get upset about it though, not a very positive interaction, in my opinion

[detox]

The SV27 motor/esc combo will cruise all day long giving it lots on/off throttle.

I think Castle states on/off throttle is bad for their Hydra esc's

1/2 throttle

interesting..........the other day i let a friend "play" with my Associated RC18R which is brushed, but lipo powered and he was cruising around for maybe 5-7 mins. at 1/4 - 1/2 throttle when it just went dead. after trouble shooting, i found the motor fried. this was puzzling to me because i just went through a 2000mah batt at full throttle 15mins. earlier with no decrease in performance. i normally run at on/off full throttle. it was just weird to me that the motor died when running at half throttle. also noticed that the motor was SUPER hot when it died.

[Boatman]

Not from me to you Jesse. I have nothing to show to prove anything. I suppose I need to quit comparing boats to choppers. When flying I am all over the throttle and I give my esc a workout that is for sure. No blown esc's to date either. It stinks his blew. really stinks. I am just scared no matter what esc to plug in my packs and not be full throttle until it hits LVC.
