OS FP .40 Engine Conversion
« on: June 30, 2018, 08:43:18 AM »
Need help I want to convert an RC FP 40 over to control line. I need the tower part numbers for the OS NVA assembly, Venturi and head gasket. I did this several years back to another FP 40 and have misplaced their numbers, can't seem to find what I'm looking for on their site. Want to put this motor on my new Fancherized Twister.
Thanks,
Steve

gasket set is; 23364000, venturi is; 2331200 and NVA is; 26582900

I prefer the 25 size venturi;22312000

Good luck, Jerry

Jerry,
Their site is awkward to navigate with a part number I guess I'll have to call them after all. I even found my past order history and searched the part numbers with the response saying the number is no longer valid. I hope these parts are not discontinued especially the  NVA. Have you ordered using these part numbers recently?

I ordered the NVA in April of 2017, I just checked my order history and the part # is invalid.  I would check with Randy Smith, if he doesn't have the OS part his PA NVA is a very high quality part.

Hi Steve, actually it's been a while since I ordered any OS parts.

Good luck, Jerry

Send it to Jim Lee.  He will return a ready to go motor at a very reasonable price.  He's converted at least 20 engines for me.  Actually he usually stocks these parts so you might just get the parts and do it yourself.

They have been discontinued  by OS ,  but you can use some of the  LA venturis, the OS  NVA  has also been discontinued,  I have venturis in stock, and I have managed to buy a  few more  OS NVAs, but I have plenty of PA  NVAs in stock, they are much better but you  would need to drill your case to .157 to  accept  a PA  needle, or  if you use the  ST , Enya, or  OLDER  OS  NVA, as the  old ones are  .157 and the  LA and FP uses  a   20 size needle  that is  .135

Randy send me a PM I'd like buy a PA for the OS FP 40. I have no problem drilling out for the larger diameter.

I can do that  but you will  need  to  use  the  .281  diameter venturi  and  NOT  the  .255 one
