I think you would benefit from buying another trainer. A Saito 100 is a lot of engine for beginners like me and you. If you absolutely don't want a trainer, a super stick would be just fine as long as your instructor agrees. If you use that engine, adjust it mechanically to stay below 3/4 throttle until you are ready for all that power. Trust me, too much speed and a little confusion can ruin your day.

There is also the H-9 PTS if you want a warbird later, it starts out as a trainer and can be 'tuned-up' as your skills increase. There are many threads here on RCU regarding the PTS.

Good Luck!!
