Morning everyone, like you say Ashley,visibly there doesn't seem to be much difference between the two,in the water it's like chalk an cheese. My vac2 runs American occurs beryllium copper x442,left and right hand,but they have been reshaped to mimic hydro style.little bit more expensive but well worth it.all part of the fun though,especially when it finally comes right. If I hadn't tried both styles of prop one after the other I wouldn't have beloved the difference. Nick

I was interested in the difference it made to your hydro pontoon,especially when you switched to lipo power.the hydro style props do seem to like lots of power.lots of prop wash,I get big rooster tails off all 3 boats. The biggest problem I had after sorting the props was getting the two drive's perfectly lined up,or else it fought it's self in a straight line and made a big difference to straight line speed.

It is just a shame that the hydro props are expensive, and generally dog-driven, preventing easy swapping between types.

​Cornwall model boats lists some Graupner plastic hydro props that simply screw on and are cheap.. I may get a few representative sizes, you never know. Need to keep them labelled as Hydro props though.

Another supplier whose very helpfull and has large supply of graupner props as well,is Tony,who runs model marine supplies. He was the fellow who supplied,polished and balanced the props on mine.he also supplied me with the hydro props on the jaguar and miss bud replica.changing the subject slightly, its a shame the magazine doesn't have a page or two for fast electric. I know space is tight,maybe an idea for the future?regards Nick

Hi all,

I run all my brushless motors on Hydro props, mainly Graupner plastic two bladers. It sometimes helps to drop down a millimetre or two in diameter than you would think as this lets the motors run at a better speed as they are designed to. I get all my screw on hydro props from Gliders UK...very good stock and service.

Cheers.........Ron.

Make your own contribution to the Website

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
