New Products mini quads

How large do you think a shroud can be before the weight kills the efficiency advantage? I have seen some props coming on the market with slightly upturned tips touting the a reduction in tip vortex drag. Maybe. I don't think the upturn is any where near enough an angle to make a difference. Maybe super light weight, properly shaped, shrouds are the answer.
 
Hi mate my 14x5.5 props have the up turned tips they do fly well , still think these are a good idea
 
I didn't mean to imply they didn't fly well. I was questioning the manufacturers claims of greatly improved power and efficiency. I noticed they don't supply any numbers to back up their advertising. I have a quad ( if I ever finish it! ) that would be a good one to do a prop comparison on. I'll keep an open mind 'till then. See? I'm learning! LOL
 
Well i do know what you mean mine came that way I didnt need to order them made with up tips , So I cant prove they work any better I hope they know what they are doing as they make them , and large air liners have the wing tips up so most be some thing in it lol
 
Just plain old Hobby king I got them to test and love the way they fly so got some spares they are on a 650 kv pan heavy lift motor
 
huh. I'll have to try those. I've been using the RCTimer for just about everything and the only complaint is long shipping times. I have only had to ever balance 2 and probably would have been ok not bothering.
 
You need to balance any prop really as they will knock out motor bearings , we dont on 250 racers due to props having a short life span will all there crashes
 
I always check new props as well as any prop that touched the ground after one of my exciting landings. Controlled crash doesn't even come close.....:cool: I'm becoming quite the expert at balancing.
