| The Type 11 has an 11 mm air intake diameter which is 1 mm larger than the type 10. I don't think it will be a problem especially since the Lotterle carb that some people use on the Webra 91 has a 12 mm air intake.
The 2º needle is not the standard needle, the standard needle is 1º50.
I saw some fuel specs for use with 3 different needles:
1º40 : 0% nitro, +/-8% oil
1º50 : 0% nitro, +/-12% oil
2º00 : 0% nitro, +/-18% oil
There are more needles and I would like to know more about the needles for use with nitro like the 2º10 and 2º20 myself.
The 15mm hals is the right one for the OS91.
Hope this helps a bit,
Tim |
