comp-arf 3.3m yak 55. too big for imac?

[TonyThomasian]

I this plane too big and heavy for imac? Is it not allowed? Whats the weight limit for planes to be in imac?
thanx

The 3.3 is the perfect IMAC plane.
None better in my opinion.
With a ZDZ210 on pipes. There power is unbeleieveable.
With that motor and the electronics, You will come around 45 ponds.
Go for it!

Lots of people fly the 3.3M Yak in IMAC.

[TonyThomasian]

sweet! i've seen one fly, but i never knew it was allowed in imac because of its weight. Thats awsome! I saw it on a ZDZ 210. How about a 3W?

[TonyThomasian]

any videos of it?

[ouch!]

You have the perfect IMAC plane, the 3M extra, according to those who have flown it, it will 3D, freestyle and fly imac.

Just fly the extra

I know im just wondering, because i was looking at it the other day and it said up to 44lbs and i thought its over the weight limit to enter imac.

[JagerBomb]

The weight limit for IMAC is 55 lbs. The yak with a DA150 on pipes is 47lbs. With a ZDZ 210 49-50 lbs. well within the limits. The plane is very slow on uplines and downlines giving lots of time to think your way through the manuevers.

Hey Mark,
How about those long vertical snaps with the 150?
Talking with Shapiro, and he says it struggles a little after the snap.
Thoughts?

If you want to stick with a 150cc, go with a 3w 157 on KS 1090s and it will have plenty of power. I have not seen this combo, but after seeing a few with DAs/1090s, the performance was anemic at best. The 157 on full pipes quite a bit more than the DA 150 on pipes, but for complete unlimited a 200 is needed.

[TonyThomasian]

Mark, the video on yours with the orange scheme had a DA sticker on the cowl, does that mean you have a DA 150 in it? looked like you had alot of power.?.?.?.?.?.?.?

It's too big for a 150. If you go with a 2xx then you lose the light wing loading advantage which this thing has. The 2.6m is a great flying plane and is on the edge of being underpowered with the 100's.
If they had a 2.9-3m size it would be much better. Granted I've flown only one, a DA150 on 1090's. However, it didn't have the power for the unlimited sequence and the pipes were too peaky. It might be OK for Sportsman. I sure wish they would downsize this for a DA150.

I think it would be a much more popular plane to get it to rock out on a 150/muffs. Minda like they did with the MX2. Kept it small enough to have great performance on a standard 150.

I powered mine with a 200 until it broke (200) now I have a 150 with stock mufflers, ok for power but definitely can use more, I will be piking up a big twin from DA at the Wram show which should be more than enough, until then I have to live with what I have.

I would think the 3.3m Would make a wonderfull IMAC/3D airplane with the proper power plant. I have been flying mine for just over a year with a DA150/1090 combo and I would agree that the power is sub optimal. I have tried two props so far a Mej 32/10 (6200 rpm) and a Air Models 32/11 (6200 +) and it will not win any vertical drag race. My plane is around 45lbs. The pipes made the engine very peaky but with a good multi point throttle curve I now have great throttle transition. I made a 8 point curve with equal rpm spacing from idle all the way to full throttle. Made a huge difference. The pipes response can be dealt with. I to have been waiting with the patience of a saint for DA to get there 200 someting out so I can get this plane adequately powered.

If you are at any elevation other than sea level I would not suggest a 150 for that plane. I fly at 3800 ft with consistently moderate to high winds which does not help either.

I love the airframe and the engine just not the two together.
