Hey rgreen24,

The plane flew very well, it was the straightest and most efficent plane I have ever flown, straight out of the box. Just set the controls to have equal movements and it flys straight, pulls great verticals and does not screw out of very tight pos or neg loops.

It was light at 4.4Kgs ready to fly. That was using a OS 140RX and pipe, futuba servos and 1400 Dura Light battery and reg, 14 Oz tank and a 2 Oz header tank and a Hyde 140 ARA engine mount, nothing special.

If you get one you just need to play with the CG to get it to fly how you like it. Because it was light I found it to be better slightly nose forward CG to get it to penetrate in strong wind and turbulence. With the CG slightly forward the knife edge mixing was very small.

Hey Dauphin,
Just curious, what's the reason for using a header tank on a pumped engine?

Hey Gregg G,

I use the header tank to stop the engine grabing air from when the clunk is outside the fuel in the main tank, as the header tank feed line is solid and in the centre of the tank.

This just keeps the engine with a constant feed of fuel and I have more trust in it when pulling into torque rolls and sounds smoother during F3A schedules.

Hi Dauphin,

Its very nice to meet you in the forum.

I also got one Otop and going to build it.

Would you like to tell me about flow rate ail, ele and rud.

I plan to use RX140 or FI 140.

Is it good for F3a? What about P-05 and F-05?

Thanks

James Hung

Hi Peterkul,

The plane is a gift from my friend while we have Asia F3a competition in Aust. Where we meet the builder of this plane.

From what those of you have seen of this plane would you consider it a widebody as say the Samragd is? Thanks, Mike

Any flight reports and/or video of this plane? Any reports of the final weight? I would like one powered electrically.

The best CG location is at the rear of wing brace tube sleeve.

Have a nice flight!

ORIGINAL: Dauphin
The model is fixable and will be flying again shortly, the reason for braking is still uncertain, the brake has come about a fatigue point in the body about 20cm in front of the tail. This fatigue at this time I believe has come from damage in transit from Thailand the Australia as the box that the fusalage was in was damaged.

When opened the box the model looked OK from the outside so I quickly finished the model and flew it. At the time it had only had 16 flights.

I must say Xtreme Composites have been very good in helping me out in trying to sought out want has happened so other people do not have this happen to them.
Composite built model out of Thailand, failure just in front of the tail, from photos construction/moulding looks very Impact like, wing adjusters but no other brace other than the pipe floor, failure on flight 16 in 'standard' flight, factory keen to help . . . my Impact did the same thing - just on flight 19!

It may be transit fatigue (and I sincerely hope it is!), but I would suggest it is worth reviewing the whole Impact experience and their public findings (see Impact threads to get to the C-ARF UK site with their full commentary) before putting it back in the air and risking further equipment damage.

David the OTOP's now come installed with a brace from the fin area to about half way to where you would install your rudder servo. Makes the fuse very stiff..

Thanks

I also noted from the other thread on OTOPS (after posting on this one!) that these were better reinforced down the rear end than the Impacts anyway -- which is good news. It is great to have competitive and well finished pattern planes in this price range -- so lets hope they have them right!
