The 200kph "out of the box" has been demonstrated on many events - measured with on-board telemetry and displayed on huge board.

The key is to have the right combination of parts. A battery which retains a high voltage under load and the right prop. The Graupner Speed 6x5.5" is so much better than the APC 6x5.5" on the FJU, that there is a very noticeable difference in performance.

Hey Jurgen,

I'm glad you mentioned the right combination of parts, you keep recommending the Graupner 6x5.5 prop.

Problem is if you buy the recommended power system from a US dealer more that likely it will included an APC 6x5.5

On the Multiplex website - no mention of using a Graupner prop, as a matter of fact, part # 73 3195 does not even have the Graupner name listed.

As for the recommended 3S 3200mAh 80/160C lipo - Look like a nice pack, At 74.00 Euros it better be.

However I am pretty sure you will have a hard time finding a handful of US FJ Ultra owners who are using this pack.

Multiplex buys the props from Graupner:

The only difference is the missing "Graupner Speed" printing.

Where you guys getting the Graupner 6x5.5's in the US? I've been flying the APC 6x4 and thought I'd step up.

thx

Hobby Lobby had them for a few days but they are gone.

I received a few spares from Icare in Canada. You might try them. http://www.icare-rc.com/ part #1305.15.13,5

Thx GS....is HL the only US distributor?? My guess is that with shipping, they're around $10 delivered (or 2x props for $15, no big deal).

Are they really worth it; ie, that much better than the APC 6*4? Recall that I'm running the Grayson hobby SuperMejaJet combo on 3S/30C

thx

Hi Jeff
I don't know if they are the only US distributor. I ordered some from the LHS and they said it might be awhile. So I did an internet search and found the 6x5.5's at icare/icarus and ordered a few from them. S&H to Los Angeles was 8.50 airmail, shipped in a box (vs envelope) with no issues. I have an APC 6x5.5 I bought as a spare before I found the Graupners. I bored and balanced it but haven't flown the APC though. Hope this helps. Sounds like a nice combo. How does it fly?
