If you’re doing the x45 route the harlock viper jet with gyro flies really big and the mini avanti are both good choices. I have a 2.5m viper as well and I have never seen any tip stall tendencies? It’s a very popular model for the very reason of being a good all around model. Small models will slowly come, three new small models have come to the market lately. Lots of options these days, you just need to decide on what exactly you want.
