radial engine mounting tips
 

Hi people and Experts! I am a minuscule scratch builder. recently facing some challenges while switching my Seagull AT-6 Texan from Saito FA-150 "910Grams" to Evelution 35cc 7 cylinder "1600 Grams" I design a mount but not sure if I need to reinforce the Fire wall! Can you please share your experience and Tips in this thread. I have few more Radials to mount Evo 77 cc 7 cylin to F6F hell cat. and Moki 215 5Cyl to Scratch build LA7. Your Experiences and Knowledge may help others.
Thank you
