Hey AirTech...

Over in this post: http://www.rcuniverse.com/forum/m_34...tm.htm#4048192

You said
quote:


I mounted the engine with a set of 2" standoffs from forgues -research.com/">Forques Research, and the prop hub is sitting right at the middle of the recommended range of 6 3/4' to 7 1/4" from the engine box. Roger Forques will build you custom length standoffs, with whatever thread size you desire, and they can be anodized in your favorite color too.


I'm thinking of ordering a set for my Yak from them. Can you give me some info on them? Good people to do business with? Quality stuff? Turnaround time on an order? Etc.

Thanks!
G,
Forques is a great person to do business with. First time I ordered I mistakenly ordered the wrong size standoffs. I called him and he kindly changed the order after they were built. Be ready to wait at least a week since he is located in Canada. I ordered mine with 1/4-20 thread on both ends, but you can have any combination of thread sizes you desire. Save some money and don't anodize them in color if you like, people won't see them anyway. The best way of purchasing is via PayPal. Good luck.

Just a quick update...

The standoffs from Forgues arrived Saturday. They're spot one, look great, arrived in a timely fashion, and the cost was reasonable. Good folks to do business with imo.

Thanks again for the info and advice on them, AirTech!

I just got myself one of these yaks along with DA50/slimline pitts muffler and 3" stand offs for the engine to go with it. or radio I will be using the following (already purchased).

- JR 9 channels radio
- 4x Futaba 9255 servos (2 for the wings and 2 for the elevator)
- 1x JR 8511 servo (radar with pull-pull setup using rods instead of cables that is, the servo is going to be mounted in the bottom of the plane)
- 2x futaba 3003 standard servos for the throtal and chock
- 1x Duralight 2000mah for the ignition
- 1x Duralight 4000mah for the receiver/servos
- 2x futabba heavy duty switches.

everything else is going to be stock for now.

what do you guys think of the above setting, do you guys see anything wrong with it?

thanks

I am looking at purchasing a Great Planes Giant 25% Yak 54 and putting a Fuji Imvac BT-43 EI in it. I had a CG yak 54 with a Satio 180 in it but when I over shot the runway this pass weekend and went to power up on a go around the motor stalled and so did the plane. I am looking to get away from glow and into gas and would like to hear from some of you about this combo and how the GP Yak handles. Any and all information will be greatly appreciated.

Can't speak for the Imvac BT-43 EI, never having flown or seen one.

The GP Yak, however, is, hands down, the nicest flying aerobatic plane I've had my hands on. The ARF quality is excellent, solidly built, and good workmanship. The included hardware is all top notch as well. You'll love this plane.

This is my first gas plane and I have a question regarding the clunk line inside the fuel tank.

I have tygon tubing and when I attach the clunk it is too stiff to move around the tank. It's the clear yellow tubing, I bought at the LHS. It appears to be the same tubing I see in the build pics on this thread.

What is the tubing of choice or what will work?

Thank you for your help.

how about some neopreme line inside the tank ?
tygon seems to hard for that purpose.

good luck.

Of late, I've done the following for both my gassers:

I went up to AutoZone, and got some "gas tank feeder line". They have some that is just the right inside diameter for common fuel barbs/clunks. After using various fuel lines in my gas can, I noticed that most of them, Tygon and all, will deteriorate over time when left SITTING in gasoline. The "feeder line" is DESIGNED to spend its life inside a car's gas tank. It's flexible as well. It's a bit pricey, but on our planes, we don't need that much of it, so you'll still get out for < $10 in most cases.

Nice idea for the tank, I don't have a Great planes yak 54, but i have a BME Yak54 is much bigger, but is not the plane I want to talk, is the engine. For all of you that did not have the engine yet, the real combo for this is a DA-50, you can not go wrong with this engine, I am shure you guys will love it. My airplane is setup with a DA-50 22X10 prop, and a hitec 805 pull pull setup for rudder,2 Metal Hidry 6V 2000 Mah batteries with 2 separate swith and batteries goin in receiver in 2 different channels for redundancy (safety). I will buy this yack for practice, looks supper great, what I like the most is the scale apearance the ailerons are with counter balance that's nice. This plane seem to rock. I got the 1.6 ultimate with a Crrcpro FI45 and the airplane rocks too. Gas is the way to go with this Hi performace planes. Number 1 reason is the fuel price. With a glow you may have in a giant plane 6 flights or 8 per gallon max at 16 to 20 dollars for YS20/20 blend, in gas you have 3 dollars per gallon no glow plug and the engine is more reliable, 9 dollars for kloz oil and you only use 40:1 mix 1 gallon = 6.2 +- . A lot cheeper and you will be the king of the air. Yes a DA-50 is 595.00 + muffler but warranty and service is 2nd to none, resale value is super Hi, and fit perfect in a wide range of new airplanes that coming out.
I start going out of glow last year I don't what to clean up the mess of oil, with gas my planes are clean and most people in my club are taking that route. Seal the gaps of your flight controls with clear monocote, this is a must. The only thing I don't like abaut this plane is the spinner, the yak's that I see from TOC, Aeroworks, BME, wildHare and composite products are P-51 mustang spinners no the ultimate bipe spinner like this one looks. Cowl is different that other Yak's too, this is taper in front, I compare side by side the Quique Somenzini Yak 54 with GP yak, Both are Beautiful, but I thing you get more with Great plane for the money, quality in hinges GP is better. I will report the flying caracteristics of both airplanes in the field, because the owners are father and son, and they expect the crasy caracteristics of flying 3D of my BMEYak, the landing and take off and the friendly handle in low rates.
I am shure this great plane will do wonders. one will be setup with a OS 1.6 and the other with a Brison gas engine. Test fly will be next week. Have fun and a super great day.

Some airplanes specially the yak I noted does that when you do the wall manuber. same with funtana90 and morris the knife. But check if both elevator going up in the same time, I give a little of left hand aileron during the manuber.

I don't think the Ultimate spinner is the closest look to scale. Actually the P-51 spinner is the closest one, but it need to be longer behind the backplate. Take a look at the full scale spiners, and compare.

I have notice this only at high alpha attitude or very slow airspeeds. Could be fatal during x-wind landings, especially with the wind form the starboard side.

thanks Airtech, now at least i know i am not alone. would you guys mind sharing your elevator travel for low rates and 3d? do you guys stick to the book when it comes to travel or you go all wild? and do you guys think getting red of some of the built in right thrust angle would help with my problem?

thanks

Thanks Swasey,

I found some neopreme at the local small engine repair shop. Same tubing used for clunks in chain saw gas tanks. $1.50/foot.
