A few questions...
1. I was thinking of using the Radix FAI V2 as main blades as I do not plan to do any hard 3D - what do you think, are there any issues with this choice?
2. What's best size of bullet connectors for Pyro 700-52 to Knontronik HeliJive 120HV? 4mm? 6mm? I really do not know... Thanks! |

1.
Radix blades are a very good choice in general, but the FAI ones are VERY heavy and personally I would not use them. Most TDR owners (including me) prefer the "normal" Radix blades. 2. You want the resistance of the connection to be as low as possible. So if you ask for the best connection, you have to directly solder it. That being said, 4mm connectors are "enough" for the Pyro, but 6mm would be better Cheers, Daniel |

+1 the FAI are too heavy...go with the Radix V2 FBL blades they are very good

Have to disagree there.
I am running the FAI Radix on my TDR, and think they suit the heli even better than the standard Radix. Cant comment on the V2 Radix, as havnt tried them, but the FAI blades improve high speed stability and have only a small effect on flip and roll rate during 3D. I'm no hard stickbanger, and I'm not saying they will suit everone who flies a TDR, but they are definitely my blade of choice for the TDR |

Dont plan any hard 3d stuff just yet. Reading about this topic, sounds like its a personal preference thing, just need to try some out.

I have tried them
For fff and sport flying they are great. They are too heavy for beating on it though. It depends on what you are doing with it.

The nice thing is that the TDR flies good with various blades, and all are a little bit different. Radix FAI certainly repesent the upper weight limit, with light 69x blades being the opposite extreme.
Flip + roll rates are basically controlled by the FBL system, so as long as staying within physical limits, difference will be marginal. Probably most pilots dont't fly extreme settings anyway. My point is that FAI are no real "allround" blades per se, and especially when speeding, you should watch your axial bearings: at FFF, they may need maintenance every couple of flights... However I agree they provide superior FF stability even at decent HS (~2000rpm) Daniel |

I tried the Radix FAI blades when I got a set by mistake through a mail order house, I flew them one day (with permission from the seller) and returned them. In my mind the point isn't whether you fly 3d or not, it is just the "feel" of the helicopter in flight. I personally like a light responsive feel even if I am just cruising around. The FAI blades are way too "stable" for my taste, they are purpose designed for precision flying hovering maneuvers and have a heavy feel to them. If you fly FAI maneuvers they will help by being less sensitive to winds and small inputs though. The heli is very "planted" with the FAI blades. In my opinion one of the great attributes of the TDR is how smooth and stable it is naturally, FAI blades might be too much of a good thing? But I did not vary my Vbar settings to compensate.
I prefer the Castle Creation type bullets that are solid metal over the "spring type" bullets where the male has a balloon shape and the contact area is a lot less. 4mm is fine, I just bought a bunch of 5mm EC5 connectors from Progressive RC and used the bullets from them. As well as using the EC5's for my battery connections.

Concur with that, otherwise no point in having the diameter, when pushed together the male spring parts just provide friction but it all squashes down so that the rest of the contact area is in contact with the femail tube.

Anyone has tried SAB blades? They are 185g. I haven't tried them yet.
