I have not started mine yet, but I am curious if there are spare parts available for it if they are ever needed. I was looking on the website but could not find any parts at all listed for it. I will be installing a my YS 1.40S.

I had to replace my cowling - I called Aeroworks, ordered it, and had it in my hands in a few days. My experience has been great support from the aeroworks team!

I haven't had the need to order anything else (thankfully!).

I do not need any spare parts, I just did not see them listed. I would like to purchase some wings bags for my .90-1.20 YAK 54, and a tail wheel assy to retrofit on my new Funtana X100. I will give them a call today.

I noticed someone had trouble hooking up to the carb linkage on certain motors. A good "fix" is to use one of the smaller servos installed in the cowling to work the linkage for the carb.

rv9-a,

I was successful in the mounting of my saito 150 in the YAK.

Looks great!!! I do have one question:

In order to have an adjustable needle I will have to use a long peice of music wire to extend the needle valve far enough out of the cowl for adjustment. I worry that the vibrations will cause needle problems.

How did you handle this situation??

Thanks

MR G

Mr G - I don't know if this works for everyone, but I've had luck running a piece of small cable from my needle valve with a piece of fuel tubing slid tight over it in the area it goes through the cowl. Drill the hole in the cowl just a smidgen smaller then the tubing so you have to slightly force it through the hole. This reduces the chance of vibration sitting there and having the wire/cable rub the hole larger in the cowl, keeps the needle valve from moving but leaves it easy enough to turn and adjust. Hope this helps you a little and congrats on getting the 150 mounted - post pictures

Hi,

Just ordered mine from fusion models here in the UK! Can't wait to get started, only prob is the missus has bought it for my birthday, so I have to wait til end Dec!! After reading all the comments and pros/cons of petrol vs glo I bought a second hand MVVS 1.60. I've got a YS110 in an Adrenaline which is fantastic but the cost of fuel is huge!

Looking to do some my first IMAC comp next year in Basic class. Will prob go for Hitec or Fut digi servos and hopefully the new Fut 7C 2.4GHz set when it's out in Jan.

Any of you Gas guys got time to post some info on ignition/rec batteries. New to petrol so trying to find out stuff atm. What is the smart-fly regulator like vs fromeco? Do I need to go for li-on ig batts to save weight?

Great pics and info in this thread! cheers, simon

This AW yak (1.2) is legal for IMAC?

GPutt,

Thanks, I noticed that on the new saito 150 it is possible to swing the carb and velocity stack to avoid th mounting bolts for the motor mount. Also flipped the carb 180 degrees.

Today I got to run the Saito 150 for the first time!!! I only got about 3/4 of a tank through it due to some issues that needed to resolve.

Issues:
The red fuel line supplied by aerowrorks was too small for the nipple on the muffler and split.
The rear wing retainer pins could not be installed because they would hit the tray located underneath.
I did not tighten the intake stack nut tight enough after swinging it over to avoid the motor mounting bolt.

___________________________________________________________________________________________

Replaced the red fuel line used for muffler pressure with standard size fuel tubing (really easy fix)
Carefully made small holes to allow the wing retainer clips to be installed ( also an easy fix)
Tightened the intake nut (super easy fix)
All fixes we completed during the halftime of the Dallas Cowboys game (about 15 min)

I did not get alot of run time, nor did I get alot of rpm measurements. running APC 17X6 15% fuel.
I did get some measurements.

It peaked at 9400, then richened it up to 8600 (make sure of rich high end) Thrust feels like it will shoot out of hover (Hollywood).
I thought I had it idling at about 1980...this is amazing this early.
At idle I pinched the fuel line and after about a second it started to increase rpm. (make sure low end is rich)

My overall opinion of this aircraft is that it is well thought out and well put together. I also believe that the Saito 150 will be an exceptionally exciting engine to run on this airplane.

I have not yet flown the airplane but I would definitely recommend this airplane to anyone, but bear in mind this airplane is NOT a trainer. After I get a couple of tanks ran through the engine I will do my maiden (still breaking it in).

You're going to love that combo! I have tons of power with my 1.80 and I'm sure your 1.50 will do the same.

For the retainer pins you could have just pushed the pins looking to the inside of the plane. That's what I have used and I haven't had any problems.

Make sure you use split washers on the wheel pants screws. One of the screws on one of wheel pants broke its head off. I replaced all the screws and added split washers. I haven't had any problems.

I love my Yak and I would recommend it to anyone for their next aerobat.

Be sure to post some pics!

I agree with everyone that this is one awesome plane. Early on there were some post of the tailwheel assembly bending and hitting the rudder, the screws on the wheel pants breaking the heads off, and my own concern when I started my build that the landing gear was not going to be strong enough. I have not had any of these issues and I take off and land on a concrete runway. I did notice when I was cleaning it up one day that the red paint on the bottom of the cowl were the three holes are that the paint is starting to come off. No biggie, it's not that often that I have someone pick my plane up and look at the bottom side. Has anyone else heard of the new Extra 260 .90-1.20 QB that will be coming out? That will be my next project if it's no later than Spring.

I'm running the OS 120AX swinging an APC 17X6 prop at 9500 rpm. Great combo with unlimited vertical. This is one of the best planes if not the best I have ever had. Aeroworks makes a great product and I look forward to the Extra 260 .90-1.20 coming out.
