We had a great turnout for our last T28 race of the year as well as the last club event of the year. Given that we are so close to the holidays I was expecting lighter turnout but was pleasantly surprised that we had 12 pilots which included a couple of newbies to racing series.
The preliminary rounds all had incredibly close finishes with several being determined by just a few feet. After the dust settled the groupings for the finals were set and the results were as follows:
Bronze (now known as “dirty gold”):
1) Ian
2) Carl
3) George
4) John
Silver:
1) Brad
2) Otto
3) SteveM
4) Artie
Gold:
1) Max
2) SteveN
3) Glen
4) Larry
Next year we will continue the series with first race scheduled for Jan 11 2025. For those new to our T28 racing series the rules can be found here: https://www.sefsd.org/club-contests/t28-racing/t28-rules-information/
All planes need to have their racing numbers clearly displayed on both the top and bottom of the wing. The numbers are assigned—send me a email with a list of your favorite 3 numbers between 0 and 99and I will check the list and let you know if it is open. Most of the numbers under 25 are taken so keep that in mind when picking numbers.
Given that a number of pilots are new to the racing series I think it would be helpful to reprint the “tips and tricks” advice:
For those looking for “tips and tricks” for racing T28s a good starting place is this guide:
Setting up your T28 to race.
The most important thing that many people miss when starting to race RC planes is that going fast is nothing without control! The FMS T28 is a small plane and setting it up to race IS very different than for your basic sport flying. Getting the CG and control throws dialed in are key to getting the plane to “go fast and turn left” and keep in control. As a racer running at full throttle— the elevator and aileron travels needed are minimal . A properly setup T28 will actually be easy to fly with only small control deflections.
The control throws suggested in the FMS instructions are intended for a plane flying much slower on a 2S battery. We are flying much faster with 3S. Here are the control deflections I have on my plane:
Ailerons: 6mm up 6mm down
Elevator: 3mm up, 3mm down
Rudder: 6mm left, 6mm right
CG measured from edge of wing at fuselage opening 71-72 mm
I like about 30-40% expo on both aileron and elevator—helps make the plane less sensitive around center making it easier to do fine adjustments to the planes track. A little nose heavy help make the plane positively stable in pitch which and the elevator less sensitivity but the recommended CG in the FMS instructions is too nose heavy for my tastes. Too rearward CG locations will make the plane neutral in pitch stability or even negative which will make it more difficult to find a stable track down the course. The trade offs in moving the GC is stability vs turning ability with the aft CG setup being able to turn more quickly. You need to be careful with the CG and elevator throws in that if you get too aggressive the plane will tend to snap roll in tight turns.
If you find the racing setting a little too mild for take off/landing and general sport flying I suggest setting up a dual rate switch so you can easily swap from one control rate to another.
Some of you did not read my previous article regarding the “AD” for the nose wheel strut—I learned the hard way that on our rough field the stock strut puts the nose wheel too close to the prop which will result in props getting busted when the blade hits the nose wheel rubber. fix is easy—just turn the nose wheel around (be sure to put a flat on the shaft on the opposite side!).
Happy Holidays —see you at the races!
