Sport Flying & RV3 Vs T18 Comparison. Hello Group. This is my first post. I am seriously investigating the T18 for purchase. I now would be an owner of a midget mustang but the owner decided to keep airplane. I then started to look for an RV 3. Then a local RV3 owner suggest I investigate the Thorp T 18. It is an airplane I have seen often but for some reason until now not seriously considered. My first impression is how comparable the two are. Both airplanes are described as sport planes capable of gentleman aerobatics, loop, spin, and roll. But no snap maneuvers for the T18, which is fine by me. The new RV3C has 30 gal fuel capacity comparable to T18. With 0320 RV3 Specs Empty wt 750, Gross wt 1100 Wing span 19'-11" wing area 90 sq ft roll rate 160/SEC? 1 SEAT T18 Specs Empty wt 850 Akro Gross 1250, max 1500, span 20'-10, area 86 sq ft roll rate 180/ sec and 2 SEATS Now a more realistic look at weight. Most basic 0320 RV3 weigh 830 Lb many heavier This site says a basic light Thorp comes in at 850. For comparison lets use 930# for T18 RV3 @ 830 empty+ 170LB pilot(me) plus 16 gal x 6(96#)= 1096#. RV3 at max gross T18 @ 930 empty+170 # Pilot plus 16 gal x 6(96) = 1196 # T18 below Akro max Note The RV3 can not carry full fuel if built to Vans Max recommended . The average RV3 seems to cruise 10 mph faster. And has a 5 to 7 mph lower stall speed than a solo T18 do to 12.22 Rv3 wing load vs 13.95 for T18( as in above ex.). But look what the T18 can do. Take a passenger. Using the above airplane with 16 gal we add another 13 gal or 78 # |

I'm sure you'll get plenty of responses to this, Tom. Yes, you can do those maneuvers - I would guess that most T-18 pilots have rolled their airplanes, and probably a lesser number do loops on a regular basis. Obviously you have to respect the limits, and be aware that the T-18 picks up speed very rapidly when the nose is pointed at the ground. There are differences between individual airplanes, and spins should be approached cautiously. It does wind up fast, and there have been reports of almost unrecoverable spins with certain configurations of the type. And... you are right - the T-18 is almost too good to be true!

Tom, I agree. The RV-3 is fun and fast, but sits only one. Share the fun and go somewhere in a T-18. |

I have owned both an RV-3 (O-290D2 FP) and a T-18 (IO320B1A CS laminar wing Wide body). Both are great airplanes and have their strengths. In my opinion they fly much different and require different techniques. The RV-3 was slower (smaller engine) but better at acro. The T-18 is a better cross country machine (especially with aux tanks) but not as good on short rough grass strips. The second seat fits my needs better as I have a passenger around 50% of the time. So for my needs only a 2 seat RV would work and at twice the money it just wasn't twice as good. I like my T-18 and plan on keeping it for many years because it is fun, fast, and unique. |
