Hi,

a few months ago I started with this hobby and I'm flying for some time now. I'm still learning because I'm having quite some problems with my plane. The first times my engine wasn't working right. Then there was my plane out of control in the air due a broken main switch... and now I can do only hand starts with my Colibri kit. I don't think the Colibri is a good trainer to learn because it's to small (I have a 6,5 cc engine) and does not fly very well.

I want to learn how to fly without instructor so I need a good ARF trainer. What do you guys recommend for a 6,5 cc twostroke engine?

suprised no one said that. I don't own this plane, I owned a Thunder Tiger trainer 40 but was somewhat not impressed with the quality. The sig lt-40 is all balsa, which is great for repairing. trust me plastic is about the worst thing to fix on a plane i have seen the lt-40 fly and flies great. i would highly recommend it to any beginner learning to fly

I soloed my fourth flight by myself and landed it nice! but it took a while after that to do it again, i say it took be a good 20 flights to land perfect and get the hang of it. i never used a sim either

Hi, I am getting a sim so I can practise more. But the plane is my problem. For some reason my plane turns full right when I try to take of the field. It flies straight, but on the ground it's a nightmare. It isn't the landing gear. The landing gear even to the left!

it doesn't roll but it just steers to the right on the ground. Just like when you give full rudder to the right. I have multiple instructors but nobody knows what could be the cause.

Hello,
I just bought and flew a Pegasus 40 by Thunder Tiger. It is an ARF. I am very pleased with the plane, great flight characteristics. One thing I liked about the kit, it came with everything, including spinner, control rods and linkages, gas tank and even rubber bands. It has a huge 70" wingspan. I put an OS 46LA on mine and it does everything I need. It is my second trainer. I highly recommend it.

Best of luck!

on the right turn problem: try hand rolling the plane.
If it tracks straight, then its thrust line and/or rudder offset. (might have cross corrected rudder with aileron and at low speed adverse yaw makes BOTH turn the plane the same way. Nosewheel and rudder should be corrected in that case.)

If it pulls off to one side, check that the mains both turn freely. If they drag, they won't drag evenly. (check that they turn freely anyway... you could have corrected for the drag with the nosewheel...)

Check that the mains are straight. if they have toe-in or toe-out, it can make steering "interresting." Visible toe angle is too much on ANY plane. Chamber angle should be as close to 0 as possible with the model sitting at rest. (thats the vertical alignment component)

check that the fuselage is built straight... a crooked fuselage makes it hard to get anything lined up straight. And then check that the mains are mounted straight on the fuselage. (or that the wires haven't bent backward... See wheel alignment above.)

A fix for wheels that wobble on the axle: drill them out and insert brass tube bushings. The tube should be a close slip fit on the axle, and a tight fit in the drilled wheel hub. You can use multiple "telescoping" tubes.

This might be obvious but I had the same problem once. The right wheel turned freely unloaded, but the hole was slightly elongated so it would bind when under load causing the unwanted ground loop.
