let down..

Thanks Roger, you are way too kind

c0sie is right in that the 56 is the easiest fit but since you already have the 81MG just make it work. It's a beast of a servo and you'll never break it. The 81MG is about 29mm wide and the RC18 chassis is 33-34mm wide so you have a bit of play side ways to get it to line up ok.

I've played around with a few servo's to get them to fit in all my micro cars (Mini Inferno, RC18's, Recoil, etc.) and I now exclusively use 81MG (or the newer 82MG) and 85MG's.

I tried the following servo's in the above cars:
Hitec HS-55
Hitec HS-56HB
Hitec HS-65HB
Hitec HS-65MG
Hitec HS-81MG
Hitec HS-82MG
Hitec HS-85HB Mighty micro
Hitec HS-85MG Mighty micro
Airtronics 94091Z
Futaba 3155

and the following servo savers:
Airtronics 94091 saver
RC18 plastic
RC18 alloy (GPM)
XRay M18 (by far the best)
2 x unknown makes

I tried various metal spings, O-ring fixes, etc.

This is how sad it got in the end
