Professor B, 1 of the many ressons I watch this channel, your willing to show step by step how to do something, and do it very thoroughly, wether it's tips,tricks,building or just how to do something. I've been running r/c boats for over 35 years and I lern from this channel all the time. I appreciate you and your channel, thank you for doing what you do.👍👍
It's soo mad how all these little mods can speed up the boat, I'm just learning how to do all this, nice one big B , learning lodes of your channel much appreciated 👊👍
Do you know what you should do? It was testing the propellers before calibrating them and after calibrating them. with the same parameters and batteries on the boat. Only then would you be convinced that this calibration is not a waste of time...
Every balancer I've used if you balance the prop then just turn the prop on the rod not the cones or rod 180° and you will get a difference result 🤔 the sound a prop makes when running really let's you know ifs balanced higher pitch whine higher rpm but yes dubros are good 👍🏼
Here's a question for you, why does abc have a different numbering system than most prop manufacturers. They all need to be on the same page so it's not so confusing.i stay away from abc because I don't know what I'm buying, but I know their a good prop.
#### is the dia 1314. so 1.3 inch diameter. 1.4 pitch prop. If you dont like the 1.3 multiply it by 25.4 to get millimeters. The (3) is for 3 blade. Then 15' rake is the angle the trailing edge of the blades is off the end of the hub parallel surface. if it was 0' then the trailing edge of the blades would be parallel with the hub end. Lastly BAR is a blade area ratio. This is the hardest to fully comprehend because its from a complicated equation. Basically the bigger the number the bigger the blade area so the more thrust. I got an ABC once that was a 1717 but had a small BAR number and it created very little thrust.
@@jimstone5339 i kinda like the way abc numbers there props, most companies don't give you rake angle and blade area measurements all handy tools when picking new Props

Return of the prop master. One can not miss any of your vids. You just don't !

Hallways a good one when it's a props video 👍🏼
Thanks mate and happy new year
That's a good tip.. Looking at reflection from a light. Do that too. Makes it easier to see small flaws/inregularties... 👍
This prop was fast today, did some ovals, then a speed pass with a fresh pack, hit 67 with a flip. Crazy fast prop
You are a one of a kind. I like that.
Ganz prima gemacht, love it!!
Cheers for the informative vid . Once again more info for the brain lol cheers
Nice work. I would still like to see it go straight on a magnetic balancer. Only to satisfy my curiosity.
Sweet B. Ever use the top flyte magnetic balancer.
I have an ose magnetic balancer, that i sometimes use for a back up or to check the dubro

Is there a chart or video that shows which prop should be used with a given race boat combination? Thanks
OSE has the abc number chart available for download
Big B , this prop looks super .
Just wondering ,
Do you ever run a 4 blade prop ?
Thanks
I have yet to try a 4 blade prop on one of my models.
I have a question. It may sound dumb but when running metal props compared to a same size in nylon do you lose a percentage of torque.??
Yes, nylon has flex beryllium does not.

Octura does a little different approach. m445 is a medium lift, 1.4 pitch, 45mm prop. no way to no BAR or rake angle.
@@TeamHeavyChevy1 are you talking to me or big B lol?
@@PatriotBradyoutube did something funny when I hit the post button, sorry about that.
