i Did Exactly the same as above, i bought my ARf plane, put it all together, them when i had the cash i bouht my TX and servos and Rx and i installed that in the plane, then it was chrissy time so i asked for a engine for chrissy and got it, now about 7 months after i bought my plane ive flown it twice. Took me ages to get it in the air, but along the way i have got just about everything you need and never once broke the bank. Patience is a virtue.
