Greetings wise ones!

I've bought a Tdl Systems (Hi-Tec Holland) Extra 330L from another modeller.
It's all going together great, but there are no instructions in the kit.
The RC Universe kit review by Bill Pryor suggested that the control throws and CG position are critical but didn't say what they are.

Does anyone have any idea what they should be? Even better, does anyone have a scan of the instruction sheets that they could e-mail me?

Here's holding my breath.................

Poof!...........nope, couldn't hold it

I had two of these. It's a nice flying plane, and the instructions that came with the plane were lacking in direction. There were no control throws listed. I used the tlar method. That Looks About Right. I think I just set it up with all I could get for throw and then went with around 40 % D/R and flew on low.

I will see if I can find the CG.

Overall, the plane was pretty tough. The landing gear structure was weak, and the horiz stab was weak. I also noticed some of my CA hinges had pulled loose. On the landing gear, I had no problem with the second plane. I put glass cloth over the formers like Bill Pryor did, then sealed that lower area and filled it with minimally expanding foam. The horizontal stabs cracked in the middle on both of my planes. I don't know if flying wires would keep it from cracking. I would try it.

Brian!
Thanks for that. Really, really useful.

It's all going together well. I'm going to use an Irvine 61 Mk2 with a BCM Pitts silencer for power. That's about 2bhp; plenty I think!
Controls will be pull-pull using wires with closed-loop compensators against Kavan steel pin hinges and I've decided to fix the landing gear using nylon bolts as a deliberate weak point. It's saved my Acro-Wot (Chris Foss design) many (many) times!
If you've had two of the beasts, you must have liked them despite the foibles.
Regards,
Carole

I did like the plane. It flew very well and is a nice size plane. It also was an excellent value at $125 delivered to my door.

I used nylon bolts to mount landing gear on a plane, and they are tough. I think you will tear gear out before breaking 1/4-20 nylon bolts.

I don't have the manual for this plane and have forgotten the CG.

Post some pictures when you get time.
