David Flynt

Fortunately I did not see much damage elsewhere. I will look into super finishing -- thank you for the tip. I found a tiny bit of steel on the bottom outlet fitting magnet, and similar amount on the ...

The technician I spoke with today does a mini refresh, like I am doing, at 20 hours run time to replace the forward gear and often the crown wheel. He said that at 20 hours, there are sometimes exten...

Posted by: @rjbender out of interest, what's the 24 tooth 'forward drive' gear look like David? 21 hour load time: Two small pits in the forward gear. No other significant wear throughout the GDU. ...

I have straightened the aluminum mounting tabs with a large adjustable wrench a couple of times on the same main wing. That thick aluminum can crack if bent too much or too many times. The main win...

@rjbender Rod, I have been using the Motul 90PA oil, however I may switch to something lighter to reduce drag this year -- a performance vs mechanical wear tradeoff. I just remembered that not all of...

@rjbender I did not open up the GDU beyond the left cover, and I won't refresh this myself, but I will ask the tech and then report back. I was quite surprised that the ratio gears look like new, an...

@raider89 I would say "yes", the priming topic is separate from gear wear and GDU lubrication. In fact, there is a thread on this forum somewhere with a Radical that does not have an oil cooler or pu...

@raider89 Thank you very much for this timely post Dan which answers several of my questions. I too could not get oil to flow by spinning the rear wheels by hand and after five minutes of trying I g...

@gwt561324 Thanks Garrett. I plan to swap my GDU, and begin in the same way you did -- before removing the current GDU, make sure that I can get oil from the return line when I spin the wheels. My ...

This is the the paragraph about priming the pump: The procedure is described here Priming of gear drive oil pump: I found that after refilling oil into the gear drive, the oil the pump needed to be p...

Posted by: @gwt561324 At no point did any fluid come out of GDU oil cooler return line. I read that lengthy procedure at Pistonheads on removing and replacing an SR3 GDU. Everything sounds pretty s...

I will guess that the louvers serve as a vent to release air pressure in the wheel wells which would otherwise create a lifting force, reducing downforce, thus reducing traction. That said, I know an ...

Other considerations are antenna placement and radio frequencies: I have heard that placing the antenna on the top of the car just in front of the dash, while easiest to install, may interfere with th...

I just bought a Racing Radios CM300D digital base station system for a new SR3. I have used Speedcom in that past which works well but the antenna is very long. This RR system looks really nice. RR ...

@raider89 It looks like these sealing washers that ANHoseFittings.com sells are an exact replacement for the GDU fittings that Radical uses. Described and linked above. Attachment : IMG_6509.jpeg...
