I am looking for a plane that is capable of 3D with an MVVS 160 gasser in it. What would you recommend to be the maximum size-weight to look for?

Thanks in advance,

Joan

I believe someone posted not too long ago that for 3d the plane should weight no more than 10 Lbs. Hope this helps.

I have one in a H9 Edge .... it's OK but not enough for unlimited vertical. it does most 3D stuff easily, but harriers and hovers are limited to right by the floor.

Apparently the h9 Edge which is smaller has even worse performance than the Edge with this engine...... fantastic engine tthough, I fly mine at the UK shows.... seldom lets me down!

Welsh3D,

What is the weight of your Edge? Do you have the new motor with the graphite cylinder?

The MVVS motor is only strong enough to fly the plane, not 3D you will need a much stronger motor do 3D with a 10 pound plane.

MY Edge is 12lbs. Attached is a pic of it in the harrier...... this takes about 1-2/3 throttle, fully vertical takes full throttle, so not really the right engine for the model, but not too bad. The glow version would be perfect.

I'm going to put one into an AK-Models Somethin Bigg<eraseraserase> 3D Freedom. This plane weighs 8.5 lbs RTF with an OS 1.20 four stroke, so 10 lbs with the MVVS should be easy. Hell, with the stock muffler the MVVS weighs less than 5 oz. more than the 4C...

Hey Welsh,

Nice looking harrier! What prop are you using with this combo? I am putting one of these motors in a Creek Hobbies Extra 330. I don't know which prop to use so any help you can give will be a help. Thanks, I am hoping for 11.5 lbs on my Extra. Hope it is not too much of a dog... OH well

Thanks

prop is an APC 16x8..... I preferred Mejzlik but damaged an end of that prop following a wheel locking up taxying- bit of a shame really as the damage was incredibly small, but i think too much to make it usable.


Should be fine...... i'm using the spoileron mix..... hopefulyl with hat on permanently during the harrier it will be even more steady.

I just got my AK-Models 3D Freedom yesterday and have only had a chance to inspect the box contents. Very nice wood, laser cut, and quality thoughout. The kit engineering is excellent with well designed light, but strong, parts. Tomorrow I will take the CAD plans to Kinkos to make a building copy. I hope to start building this weekend.

The current selling price is $124.95 with free shipping, and I think it's a bargain. See:

I am going to try to build the kit and cover it as much as possible so that I have a good idea of the weight resulting from my building style, R/C equipment, balance, etc. I usually build using mostly white glue and try to minimize the epoxy.

After I have built it as far as I can, I will select an engine. Like visioneer_one I would like to try gas. There should be a fuel load weight savings because of a smaller tank and about half as much fuel compared with glow.

Anybody flying one yet?

Bruce

Do you think it is possible to put it in a Kyosho G-Trick 90? Will it fit? Is it too much motor? Will it clear a 16 inch prop?

Hmmm, not a good idea-weight!

Robert,

Do you think it's too heavy for this plane?

Yes, and it won't give muh of a power advantage over a YS 140L. For some reason, people are forgeting that lighter planes are better flying planes. Its not the amount of horses you an pack under the cowl. For the G-Trick, I would go with a YS 110.

Robert,

Maybe I am missing something. I am looking for a plane for my first gasser that I would like it to be an MVVS 1.6. I am not looking for a power advantage but I do not want less power than with a glow. The G-Trick is designed for an YS91 that weights 750g. Many people are powering them with an YS120 that weights 880g. I am supossing that the MVVS is producing aproximately the same amount of power and it weights 1050g including the ignition. The difference in weight between it and the YS120 is easily offset by the smaller tank capacity needed due to better fuel economy. So, where is the weight penalty? Why donīt you think it is a suitable plane?

You said it yourself, 'The G-Trick is designed for an YS91' .
You will be adding 300grams to the front, so another 300 to the back to balance, plus a bit of extra glue here and there because I hear of quality issues. So, even by being generous, we are adding roughy 400grams to a feuled plane with a YS 91. If you want to put a gasser in something, look for something that is designed for a gasser. I hear all the time of people who say that they used to put big gas engines in all their planes, and thought it flew wonderfull. They then replaced it with a smaller, lighter glow, and it is just a whole new plane, alot better at everything!
But at the end, I suppose whatever makes you happy!
Rob.
