The space on the left side between the engine mount beam and the inside of the cowl is 25mm. The right side measured from the engine mount beam is 35mm.
I have not completed full installation yet, I still have the ignition module, refuel valve, engine fibre optic kill switch and 3 batteries to install before I know how much dead weight has to be added to achieve recommended CG.
When I purchased the E-flite retracts I paid a total of $419.00cdn including tax, eh.

Hi Roger,
I see the pictures of the fire wall from the differentthreads as I surf for info. The FWD firewall Box is fairly easy cut and shortenby 2.5 cm. Yes it involve some work…( and make sure it is there to stay…)
Whenever you do your CG please let us know. Reading the treads most people add between 14to 16 oz ( 14 ounce = 396.9 g) The weight difference between an EVO 33 and an FG-36 is +361 gram = 12.73 oz. Since your power plant is +/- 2.5 cm forward I think that you will be very close to the sweet spot, slightlynose heavy for the first flights. (weight data from manufacturer).
Personally I prefer to active weight than dead weight.
EVO 33GX = 1384g
FG-36B = 1745g
FG-40 = 1715g
