Using a .21 engine I used my chassi [5 mm tick ] added slots to be able to use the     “Stock “ WLF066  .21 conversion and my version R40 recess fly wheel . turns out        do to the bigger engine the exhaust side brace can not be used ? To make up for     the loss of the brace I included my brace and servo stand which I in my opinion          makes up for booth braces .                    

WLF071- includes the WLF066 .21 conversion- chassi and braces ---- $95.00                                 Limited quantities - depending on chassis in stock.
