I'm not a beginner but this is a new one for me and I know that many experienced modellers frequent this forum.

Here's the problem. The SC52 four stroke throttle arm is 4cm below the servo arm and 1.5 too far in towards the centre of the fuse.

I'd like to do a good job with the linkage but there isn't an obviously simple, clean and tidy way to do it.

If I drilled a hole in the firewall right behind the throttle arm it would be at or just below the tank tray which can be seen at the left in the fuse picture. The linkage would need to run along below the tank tray and then right up to the servo arm. The angle would need to be extreme and then how would you connect it to the servo arm ?

What I have in mind is to move the throttle servo (maybe replacing with a 9g sub-micro) from where it is (the top one in the photo) and mount it on blocks glued to the forward landing gear mount. I could then have a short straight linkage with no binding. This risk there would seem to be that if the landing gear plate gets ripped out then so does the servo and maybe the RX as well. There doesn't seem to be anything else that I could fix it to in that area though.

And to make things even more interesting, having got the mount on the firewall and drilled for the engine, I discovered that I'd not left enough room to have both a bolt for the mount and one for the carb in the same vicinity. You can see the problem in the third photo. I suspect that everyone would say that four bolts are mandatory so I have the option of either fetching and drilling another mount with the engine further forward this time or maybe drilling another hole a little higher up in the mount and firewall. The latter seems quicker, easier and cheaper.

Any advice about these two issues from more experienced modellers please ?

Thanks
