26" cat that I built

[kfxguy]

Fast, are you running a .187 flex?

Yes. I thought about going with a smaller one but I had a mbp .187 collet on hand and I knew this 36mm was a beast and may snap a small flex. I was right too as I snapped the first one with the prop being a lot deeper. Also didn't help that I've been making my own flexes and cheaped out on solder. Silver bearing solder is the only way to go. That's what I used on this flex.

Maybe try using some Gundert 5mm flex -- I believe it is also hardened... but you'd have to sand it down to around ~4.8mm for them to fit the MBP .187 collet.

You ever tried this? How did it work?

I'm about to in my twin mystic... almost finished with it ... i'll let you know how it holds up. But I know Manuel used or uses it in his builds (he made mention of it in an older HPR115 thread).

Well I think that 3/16 is more than adequate for this. It was mainly a failure on my part. Testing my hand at making flexes. I think I've got it down pat now. I'd rather lose the prop on my boat than a customers boat anyway.

A .187 looks pretty tough, you must be layin down some torque .

Well I think it's mostly my fault. The solder I used wasn't near as strong as silver solder. I'll see if this flex lasts which I have a feeling it will. But this little motor does have some serious tq. It's equal to a 4050 sized tp. I may be going down on kv soon. This boat is just too fast at this point to enjoy.

I took some family pics just to give you guys an idea how little this dude is.

Next to my 32" Rivercat






Mini, Rivercat, shocker, fantasm

Nice looking fleet.

Nice looking fleet.

Thanks. That's not even half what I have tho lol. That's just the ones that are built. The fantasm is almost done besides motor mounts and battery trays. I have another Rivercat hull I'm collecting parts for to build a twin. Then I have a voracity, zelos, shockwave 26, mini mono, blackjack 9, carbon 37" Daytona, a Etti demon rigger and a kbb34 and another mini hull on the way. Whew. I need to sell some stuff.

[Beaux]

Nah! The more the merrier.

Are the props on the two smaller boats detounged and back cut some you worked? they look good.

No, all I did was is sharpened and balanced. No mods at all.

What brand if you don't mind me asking?

Abc.

1615 on the little cat and 1915 on the big one.
