Renan Ghelardi Posted December 25, 2016 Share Posted December 25, 2016 Hi, dears. I would like to share with you a question. What is the difference of the propellers Helix and E-props? I saw in a discussion in the French forum that the E-props is lighter than the Helix, on the other hand, the E-props has less force. Could someone share an assessment on the propellers? Thank you! 1 Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted December 25, 2016 Share Posted December 25, 2016 We have two identical moster + engines here in the Parajet zenith and the maverick. One has the helix and the other the e prop. I have not flow with the eprop yet but will give my personal feedback when I do SW Quote Link to comment Share on other sites More sharing options...

morgy Posted December 29, 2016 Share Posted December 29, 2016 Personally i prefer the E props.. The weight of the E prop blades are much less and will spool up the power much faster than the Helix, I have seen some quotes that Helix give out more thrust but i doubt anyone could tell the difference on the ground or in the air as it was only 2-3kg thrust difference between the two, For me the feel the quicker power delivery, fuel economy is much better with the E props, Also the E props are FULL Carbon compared to the helix's Fibre make up.

admin (Simon W) Posted December 30, 2016 Share Posted December 30, 2016 Morgy, the e-props are NOT full carbon. Nor are they autoclaved carbon. (I have seen the low temp polyurethane filler inside) Having now flown the same engine with both props I can honestly say that the difference is Sooooooo subtle that your average pilot would not notice any difference at all. For me, I would simply put this down to cost and go for the slightly cheeper Helix (which is also filled with polyurethane) The confusion is that Helix use 2 layers of 2x2 (200gm) carbon and back it up with fibreglass. E-prop uses 4 layers and no fibreglass but is still filled with filler. (the weight saving is because fibre glass soaks up 4 times its own weight in resin where as Carbon only soaks up about 80% of it's own weight If ANY carbon manufacturer were to make a (true carbon prop with no filler) it would take 4 to 6 laters of 200Gm pre preg, baked in an autoclave under immense pressure. (thats your F1 carbon. A prop made this way would cost £500+ If it spins, and makes thrust, is balanced and fits your machine, go for it.
