Hey Dauphin, apart from what happened to the plane. Did you like how it flies? Any bad tendancies?

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.

Thanks again for the reply!! It sounds like a great bird!!

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.

Great to hear that it can be fixed Dauphin, very sexy plane compaired to an Impact.

Hey Dauphin,
Can you post a schematic diagram of your fuel plumbing set-up please ?

This may help Lancair-RCU,

Vortec, What comes with the plane, like servo trays, wing tube, motor mount and the like?

Sorry tph1,

I dont actualy own this plane. Dauphin owns the one i took photos of, so you'll have to ask him or any one else on this thread that has one about what comes with it..

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! James Hung,

Where did you buy the OTOP? I am looking for a new F3A.

Thanks in advance
Peterkul

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.

James Hung

Thanks Janes for your fast reply.

Have fun with your new OTOP.

Peterkul

Hey Vortec, what size spinner are you using on the OTOP?

Thanks

I really like the red and white OTOP!! I want one!! More PiReps appreciated!! How much again??

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

Here is OTOP Extreme and it's producer on photo. The Supertigre G2300 installed without tuned pipe still fly great, 3D wings stab. also available.

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

Anyone out there know the best location for the CG on this bird

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

Have a nice flight!

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!

David

Ok,

So where can I get one of these things in the UK?

Cheers
