Good choice foamy, probably the best 90mm EDF trainer you can buy. This is my bungee launcher version, running on 6S. Lot of space to fit any battery configuration. I use Wemotec/ARC3675-1/80amp ESC, but I use it now only as 6S. My other model (black) with the landing gear I mainly flew on 8S fell apart mid air because I have not reinforced the wing with C/F spar. As a 6S set up I would not worry but it is a must for 8S upgrade. Use some good metal gear servos on Elevator for play free operation. Joe.

Matters what blade blade your Fly Fly fan is, if it's the 7 blade it should work on 6s for around 90 amps (make sure to get amp meter) for 6+ pds of thrust.

If it's the 6 blade fan you can get around up to 6pds of thrust with a 1700 or 1800 kv motor on 6s\80amps.

Both of the aforementioned motors will work well with the HK 90\100 amp ESC, use a spark resistor...those HK escs will take some amps, they don't like hook up spark though and a spark resistor is really cheap insurance.

Both of those set ups should give some good decent speed for the price, the CMP T-45 can go over 100mph with 5.5 pds of push. The CMP t-45 is a composite plane though....both set ups should cruise around on 5s 3300 mah bats too.

Like Jofro said, reinforce it with CF (hk sells that too)...for some reason t-45s beg you to fly em fast
