RE: Aztech / Slipstream RV-8 30cc assembly
 

I just used the plywood mounting tabs that were already there. Since this is a sport model, I saw no point in trying to hide the screws inside the cowl. I guess i'm just not that much of a masochist. : )

RE: Aztech / Slipstream RV-8 30cc assembly
 

No, attaching it from the outside as well. I just used the masking tape method of determining the inside hole to transfer the hole location to the cowl as attached pic shows. I have a tool out at the airport called a hole duplicator to do the same type of thing which would have been perfect for this but the tape was almost as easy. [8D]

RE: Aztech / Slipstream RV-8 30cc assembly
 

I use a similar method. Always best not to over-think things. I've found that if I make cowlings as easy as possible to remove, I'm far more likely to inspect things as often as I should.

RE: Aztech / Slipstream RV-8 30cc assembly
 

<ul>[*]Hi gang! When i read your tread this morning... i can't resist and buy one from AMR-RC here in Quebec. I need to know if the hardware setup of the elevator pushrod isincluded?or is it a modification you made? I will receive it in two days but i need to know... I think this plane will be THE plane that i search for a long time forthe RCG 26cc i buy lastyear and didn't find the good plane for... Itake the white and blue model[*][*]<span lang="FR-CA">

RE: Aztech / Slipstream RV-8 30cc assembly
 

The elevator linkages on mine are stock. I used two elevator servos, though only one is needed if you use the supplied wire elevator-joiner. You should be fine with your 26cc engine. Mine is almost over-powered with a DLE30. Don't install your batteries until you check the CG, as you may need to move them around a bit to balance the airplane. Let us know how it goes.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Thom.
I installed one 90Oz servo to operate my elevator. I would recommend a single servo, more than enough with your 26cc. I beleave that will be about the best engine size for a RV8. As I am very happy with my DLE20.
Hope this helps,

Welcome to R/C Universe!

RE: Aztech / Slipstream RV-8 30cc assembly
 

i change my mind and buy a new RCGF 32cc... fromAMR-RC hear in Quebec. I will fly it this week and i made 3 set up for the engine. First the 32cc RCGF second 26cc RCG and for the finale Fuji 43cc. The firewall is ready for the 3 engine all hole drill and trottle set up ready... I put Hextronique 5010 all around but a digital metal gear on the rudder... i knowit's overkill becausei take it on my 35% Cap 232... I will let you know how it will fly and possibly post video of it next week.I will fly the plane on ski.

A+

P.S. excuse my english i'm french from Quebec...

Thom</p>

RE: Aztech / Slipstream RV-8 30cc assembly
 

Sounds very interesting Thom. Look forward to a report, & video's if possible.

P.S., your English is fine, just a French speaking Canadian from Quebec.

I am running a special throughout this month so check out the [link=http://shop.aztechaeromodels.com/Slipstream-30cc-RV8-AA-ARF-SS-RV8.htm]website[/link].

RE: Aztech / Slipstream RV-8 30cc assembly
 

Wow...nice info regarding 80" RV-8 . . . , which I also own, but my setup is a bit differently with SAITO FG-36.
I didn't fly it yet as I just completed setup and started with testing on the ground + braking in my new SAITO FG-36.
I have 2 short video clips with testing engine and smoke pump on the ground at Toronto RC club field.
https://vimeo.com/55074461
https://vimeo.com/56392761
SAITO is much heavier compare with DLE30-35 or O.S.-33 thus I got 6.7kg weight w/o fuel and smoke pump.
The plane is nose heavy with SAITO, but I managed to put batteries and other parts as close as possible to the tail.
Also 2 servos for elevator helping to keep CG on the right place.

Over 5" of snow fell in my area overnight, thus I may wait untill spring with maiden fligh.

I am also looking to replace original SAITO ignition box with new one, which has improved sensor and re-designed ignition box with connector for RPM reader.
Looking forward to see more info on your experience with 80" RV-8.

One more: I have noticed that flaps for this big plane are too small and the angle of attack is limited.
Has anyone try to add more surface to the flaps?

Andrei.

RE: Aztech / Slipstream RV-8 30cc assembly
 

I built new flaps for mine. They were not larger, but they hinged at the bottom to allow much more deflection. (90 degrees) I wanted flaps for drag, not lift. This airplane is a floater. I set up the 90 degree flaps purely for additional drag, hoping to reduce the floating and increase the sink-rate. It worked a little, but not much. A friend fell in love with the airplane, so I sold it to him. He still has it. I went back to my Great Planes 1/4 scale RV-4 with a DLE30 and never looked back. Your RV-8 will fly fine, just be ready to watch it go right on by on several landing attempts until you get the hang of it.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Our RC field is bumpy.
It is on top of 25 years old dump field.
Due to this fact (untill field leveled again) I am looking for the way to slow down all my 5kg and up planes.
On some I have installed air-brakes on fuselage and they working very well.
On this one I am thinkink to add "sliding" down extra flaps like on any passanger planes if you seen them on landing.
A bit complex, but it should work well.
As you I am going to use flaps for braking speed, but not for extra lifling at slow speed.
Thank you for your comments as I may also consider flaps with bottom hinges in order to get close to 90 degree position.
Andrei.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Pretty opinionated about the flaps for someone who hasn't flown one. I own a real RV-8 and wish I could get as relatively slow as this plane can on final and still be in total control like I can with the model. I can tell you that I think the plane lands ridiculously slowly with relatively low roll out without even going to full flaps. I don't even like full flap landings, I think it's prone to tip stalling with the amount of full flaps I have dialed in. I don't know what my half flap angle is but it's a lot, probaby 45 degrees, and I could land this airplane on any RC field worth calling an RC field. With the slightest head wind I can almost land the plane at walking speed and freak fellow club members out. With a decent head wind I have had it just hang almost motionless over the runway on short final and have had to give it power to get it moving. It is a floater but that equates to very low stress when it does settle down as long as you never stop flying the plane. I forgot the weight of my setup but it's light with a DLE 30. Unlimited vertical takeoffs even with full tank. Fly it before messing with it. It's fine as is, work on your landing skills if you really disagree. I can land it where I want to now that I've got a few flights under my belt.

RE: Aztech / Slipstream RV-8 30cc assembly
 

I maybe interested in this, looking a good size civilian.

RE: Aztech / Slipstream RV-8 30cc assembly
 

I was going to retire my old GP RV-4 and replace it with a new one but they discontinued that model. I was very happy to find this plane on the market for a great price and at 80" makes it even better.
I already have everything I need to put this together just need the airframe.
I have a DLE30 and a RCGF32 but I may just use the DLE since the plane was designed around that engine.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Here's my GP RV-4 with an XYZ 40 twin from ValleyView. It would work great in the RV-8, too. Same weight as a DLE 30 and has buckets of power. 16-14 APC @ 8000+ rpm.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Here is my recently completed, but not yet flown RV-8. I used a "new" (been in a box in my garage for 8 years) vintage Brison 2.4, Tech Aero IBEC, Fromeco A123 2300 mah battery and JR DS821 servos all around.

RE: Aztech / Slipstream RV-8 30cc assembly
 

How did it balance out for you, and what size prop?

RE: Aztech / Slipstream RV-8 30cc assembly
 

The prop is a Xoar 20x8 and the balance is not yet set. However, I know it is a little nose heavy... I used 2 elevator servos since I expected it to be nose heavy. In hindsight I should have got the lightened back plate from Tru-Turn... I don't expect I'll need more than an ounce or two of lead in the tail to achieve the CG on the wing tube...

RE: Aztech / Slipstream RV-8 30cc assembly
 

The 2.4 runs very well with a 20x8 prop. Since they are a little on the heavier side I was just wondering about the balance. Sounds good! Should have power to spare!

RE: Aztech / Slipstream RV-8 30cc assembly
 

FedEx delivered mine today. Good looking airplane. Can't wait to put it together.
No Instructions, WTH?

RE: Aztech / Slipstream RV-8 30cc assembly
 

Check the first page of this thread. Mine didn't come with instructions, either. Didn't need any, as it turned out.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Finally got to fly mine last Sunday. The Brison 2.4 is well simply awesome. After sitting in a box for 8 years it was a little hard to get primed, but once it started it ran beautifully. It is very smooth even though it is a bit rich...

The RV-8 is quite simply a joy to fly nothing bad to report at this time...

I too didn't have a manual and didn't need one... The CG is on the spar and the controls are set for maximum throw and then I backed them down to 60ish percent, plus expo, for the first flights.

RE: Aztech / Slipstream RV-8 30cc assembly
 

Almost done with mine now. Hopefully I can maiden it next weekend.
It's further along than the photo shows.
