8mm or 5.5 bullets

[larryrose11]

On connectors, Does anyone use 6.5 mm? I was planning on using them on the motor. Isw there anything wrong with the Castle 6.5 mm connectors?

+1 with Ken.

Side note, I had standardized all my boats using 6mm connectors a long time ago ONLY because Steve was out of 5.5 when I built my first boat.

I recently had a 6mm motor connector desolder when I tested a big prop on a hydro. I was out of 6mm but had some 5.5s lying around so I changed those to 5.5. It was then I noticed that I get a LOT more connection area with the 5.5 as they are much longer than the 6!

Could be my imagination but I think the 5.5s are running cooler...

I will never buy another castle connector. I spent the extra money thinking I was buying quality and I was sorely mistaken. Went to the OSE and Hobby King 5.5's and havent looked back. I use strictly the HK 8's as well.

Its not about desoldering for me , its about low resistance.

FYI the castles I had loosened up with a little heat then desoldered. Not just one were talking multiple pairs.

Are you referring to the old bullets? Or the new green connectors they just came out with? I'm using the new green connectors and have had no trouble with them what so ever. Bullets were redesigned so hopefully they're better...

I have over 50 boats and probably over 300 boat battery packs and use 6mm on everything (the cheap ones and good ones both) motors speedos and batts. I have never ever had one single connectior failure. Ken uses the 5.5's and he has some pretty insane setups. The 8's are really nice but at this point changing would be a logistical nightmare.

Hey Mike. So, on your Q sport whip that you were running last weekend, there were 6mm bullets directly off the hydra 240 esc?? ....and then those split to two more 6mm's for parallel batts?? Lmk. Thanks.

K. Will go with 8 on batts and 5.5 on motors.
Boats are a 36 deltaforce and a 36 team beleviever. 180 turnigy and leopard 4080 1600 kv. And have a castle 200 amp for the team believer but not sure what motor to use yet. What would I need on 6s and what prop to push it over 60mph reliably.

Neu 1530 1355kv should be plenty. X452 ,X455, or detongued prather s245 s250.

Hey peter I did not run parallel on my whip I ran 2 separate 3S 6000mah in series to give me 6S 6000mah hope that helps. I was running a 1527/1y with a Prather 250 prop with some considerable work done to it.

What size bullets are you all running for your safety?

[NativePaul]

I use 6mm on my safety loops personally, but use whatever you put on your battery, you already decided they were up to the task so no more thought is needed.

[Mulisha]

That's why I ask so everyone who said they use 8mm on batts has 8mm safety loops otherwise it's pointless?

[nobbiworld]

Safety loops arnt required in the USA.

[Mulisha]

I just use 6mm haven't had any troubles (do safety loops add any resistance, plus usually have to extend the wire a little?)
