One major disadvantage of this type of setup is that the electronics cannot be easy used in other models. Remember this if you plane on progessing to more advanced models.

So if you buy an arebird or similiar package deal and want that second plane you need to buy all your electronics and motor again

Simple example:

1st Plane aero bird 170.00

2nd Plane Word Models super sports 40 ARF 99.00
entry level four ch radio 140.00
TT .46 engine 75.00

Approx cost of 2 planes 484.00

1st plane .40 RTF Trainer (Horizon alpha, Hobbico, Tower Hobbies etc) 300

2nd 2nd Plane Word Models super sports 40 ARF 99.00
Re-use radio and engine

Approx cost of 2 planes 399.00 Savings of about 85.00


Not saying you should do this just pointing out that after the initial investment if done correctly alot of gear can be reused thus reducing the cost of future planes
