Title: What will work in a LA 15
Post by: Paul Taylor on January 05, 2008, 12:49:29 PM

Can I take a remote NVA from a LA 40 and use it on a LA .15?
I guess my question is will it work if it is bigger? I know I might have to drill a hole in the mounting plate.

Thank
Paul  H^^

I wouldn't expect stellar results, tho I'm sure you could get it to run. I've used remote NV's a couple of times, and I think the only time they really work well is on a high pressure fuel system, like a bladder tank used in combat or free flight. I would suggest using .15FP parts, including the backplate.  H^^ Steve

Paul - yes it will work.

most of the OS engine parts will work on any size engine of their range  - the Rear NVA does leave a little to be desired tho

Hey Paul: I have the remote NVA for a LAS 15 which is part of the back plate. If you have a regular 15 fp NVA I'll swap or you can just have it if you don't.

.I would think it would work, and if it's bigger, you might only have to open it up a turn or two, and the adjustment might be tricky. Is it the newer style, what I call "barrel type" with two O rings that are supposed to seal out air? If so, and it does work, you might have problems getting the needle right on certain days. I wish they had not gone back to that style of needle.
   The type of needle that was on the FP series rear needle valve engines worked pretty well. It was basically the same needle as a standard C/ L needle valve assembly. It was set up with a metal bracket, and could be mounted several ways to make it convenient to reach the needle. I have had several models set up this way to make it easier for my son to adjust the needle when he was younger, and they all worked well. The only issues I had with it, were you had to choke the engine a lot more to start it, and it didn't want to shut off off cleanly when the tank ran dry. Tilting the back of the tank outwards helped that.
  The last time I checked Great Planes/Tower Hobbies still had the bracket, spray bar and needle valve assembly in stock. It should work well, but you may have to tweak the set up a bit to get there.
  Good luck and have fun.
  Type at you later,

Tower has the the through NVA and CL venturi for the LA15, should work in the FP.
