Wayne is going to mount a DA 150 to himself and fly around. Stay tuned.... really..

The thing at Larry's is a 3 Day open fly-in. No contest, no rules on what you can bring to fly. The only rule is to have fun.

That's overkill...
I think a DA-50 with tuned pipe would suffice..


OK, serious question. I am mounting the servos in the stabs. It seems that the servo wire is getting pinched under the servo mounting rail (Where the servo screws go).
Is there any way of avoiding this or is it OK.

there should be a small notch on one side for the servo wires to go along side the servo, our's was a sort of tight fit, but ended up working fine.

The manual tells you to cut a slot... I used a rattail file and filed a slot... see here:

Just finished mine up about 5 mins ago. All up dry weight is 16lbs 15.5oz. Now before anyone starts freakin out about the weight...It's with the KS 1060 Pipe, 24oz tank, and Tru-Turn spinner & 2X 4400mah li-ion packs. Im not worried about the weight at all considering that my DA-50 and Pipe just came out of a CA 2.3 meter Extra that weighed 19lbs 9oz which was still balistic and pulled out of TR's easily. I'll shoot some pictures after the test flight which should be Sunday or Monday. (have to spend tommorrow practicing for a contest next weekend.)

Overall, Im blown away by how complete the aricraft package is, and how easy & fast it went together.

Thanks Shortman! she's so pretty I almost hate to fly it I'm considering adding a female co-pilot up front...dang.. I need to get out more

Today during my radio set up one of my elev servo went dead. Was moving fine but it started to move slower than the other servo...then it went dead.... thank goodness it didn't happen on the flight [:@] using 6v regulator and JR matchbox on a Hitec 5945..... there is a current going to servo but just no movement. There is a little resistence when moved by hand.... any ideas? it's a brand new servo ! can't be bad already???

Can you run the servo's on separate channels? I don't use matchboxes so I may not be much help. bring it over tomorrow and we can look at it. Ron

David (Maudib) I was wondering how your ballance come out. I know you mounted your throttle servo back further to avoid any radio problems. Now I'm wondering what batteries you used and where you mounted them. I see some of the guys have the reciever battery right up front. Also what pipe are you using. I'm using the DA50, stock muffler, 4400 Lipo, 2000 lipo, 16oz tank in the origional location. I don't have the engine yet and want to start mounting what I can, so I'm wondering where to put everything. I can't remember if your using a pipe, but if you are i guess that would throw everything off by comparison to my setup

P.S. I just wanna run this past some of you. I have made an observation over my years of building. I've come to the conclusion that if your lonely and want the telephone to ring, your wife to want something, or somebody to come to the door, all you have to do is mix up some two part epoxy.

That looks great !!! It looks very .....umm familiar, yet different Did you make the toggle switches? Or was that another "set" from hobby lobby? And just curious, why did you mount the instruments to the outside of the panel, rather than installing them from behind through a hole, that is why they have a flange on them.

Is everyone using the recommended 12" servo extensions on the ailerons? They seem a little short to me.

I am curious what lengths everyone is using on all surfaces.

Man, those SWB arms are the "cat's a**"!!!! Those are sweet, and work like a charm! Also, for those of you that hate installing the brass grommets in the servo "rubbers," then you need to get the inserter that SWB sells. I bought both styles, and they are sweet! No more tearing my fingers up!

I am using 36" extention on elevators
12" on ailerons
18" on throtle
6" from RX to aileron extentions

on the ailerons they seam to be short, but they get to the RX fine!

I am not using any matchboxes or anything like that, every servo its pluged to a diferent chanel, if you have a computer radio just make the mix for ailerons and the elevators!

Gotcha! I forgot about the extensions from the receiver to the aileron extensions. I was just going to plug directly into the receiver.

I am using computer radio mixing also, so each control surface has its own channel.

My Yak has the Chip Hyde Quiet Pipe... It balanced with a 4400 mah lion just in front of the wingtube.

Based on what you have you can leave your battery out til last and balance with it... probably near the wingtube somewhere... the guys needing up front have the tuned pipe and/or CF spinner. You shoul dbe good to go...

Now THIS project ont he other hand will probably take some hoop-jumping to balance... here's some purple power...

I used 1" blocks (temp ones shown) to space the prop adapter out to 7"... Looks like .25" offset centerline gets it right with the approx 1.5-2 degree right thrust in the firewall...

Voltage regulator question,

If we put aside Fromeco and Smart-Fly, is there something wrong with the MPI 6V regulator. The specs are good, it's very lite and only $19.99. I don't recall ever reading about them in the Yak discussion???
Anyone using them? They look perfect for ignition.

6-Volt Regulator
$19.50

Key Features:
• When input is higher than 6V/5.4V, it will regulate output to 6V/5.4V,
• When input is less than 6V/5.4V, regulator is bypassed,
• Weight only 0.4 oz,
• Current: 10 Amp continuous, 20 Amp peak @7.2V input,
• Input Range: 4V -8.4V.

Thankx!

I've used them with no problems on ignition... but though they are rated at 10 amp... well... let's just say that ain't the case.

Even if it was capable of it, the single connector is only good for 3.5 amp contiuous... weakest link...

I did some tests on my Yak with the Watts Up meter... sitting still it drew a little over 1 amp... Throwing the surfaces around simultaneously spiked it up to 2.5 or so... and that's under no stress... In the air peaks of 10 amp or more are quite possible, with average being 2+ amps...

That's on a plane this size... and for me that's too marginal on a plane with this much invested. Certainly worth the extra $20 on the receiver.

Again, on the igniiton, I don't see a problem using it.
