. I suppose you could check up the thrust figures for the old F4 unit against the new F15 in-runner unit to confirm you will get more thrust before you splash the cash. You might have to find that info from someone like R.c. Castle or search Ali express. The model sits well on the runway with a good angle of attack so it looks like it is just a question of more power !!!! . ( I assume you did not want to risk more elevator in case it stalled on take off ). One of our members bought one of the older F15s a few years ago at a swap meet and he only had 5s batteries and was too tight to buy 6s and we fly off grass. The field could have been 3 miles long and cut like a putting green and it still would not have got off the ground.
