I just finished a pair of Hackers. One has a Norvel with a 6x3 and one has Tee Dee. Covered them with scraps of low-temp covering. I have flown the Norvel powered one. Running the suction tank and found out real quick that it would turn quick enough to kill the engine. Never flown combat and most likely won't, but the Hacker is a blast to fly. I'm got them so my son could learn the stunt pattern. I like it!
Hi Allen, Muffler pressure will not cut it when trying to get constant fuel delivery
when flying a 1/2A Combat model. You absolutely will need a fuel bladder tank.
Phil Cartier has the components to make bladder tanks and I believe he has bladder
tanks ready to go. Reach him at his business: The Core House
Your Lil Hackers will fly much better when you change your 6 X 3
for 5" X 3" props. The 6x3 prop holds those engines back too much.
The model will fly faster and turn much tighter. The larger dia. prop will be okay
if your just learning to fly a 1/2A Combat model... for several first flights; change to
a 5" X 3" as soon as you can.
If you want to your son to really learn to fly Stunt; then I strongly suggest you buy
him a two-line Stunt Kite, attach both lines to a single 15" handle, and fly it on 75'
length lines. Fly in medium wind: 08-12 mph (approx). We've taught many new flyers
using stunt kites; and all of the neophytes(9-40 yrs old) were able to fly insides,
outsides, and lazy eights on their very first powered control line attempt.
You'll save a small fortune using a stunt kite as a primary trainer.
Best of luck;
