Calling all Dandy owners: If you have a Himax...

I would like to power my Mountain Models Dandy with a Himax 2808-980. Here's my question:

Will I have to modify the nose of the plane to accommodate this motor? If so, how do you suggest I do this?

Before I buy this motor, I'd like to know if it will fit as is or if I'll need to do some modding to fit the 2808 in the nose of the plane.

Any help/feedback is appreciated. Thanks!

It should go right in. No problems when I did it in one of mine.

The Himax 2808-980 is a perfect fit. Use the supplied prop adapter.

If for some reason you should have to mod the nose lots of the plastic soda and water bottles fit over it well. Just paint the inside to match your plane.

I have a 2812-0850, 3S TP 1320 and SF9047 and it flies great. Last week I had a 22-minute flight with acrobatics. Great plane and setup.

No mods to the installation.

Good to hear it. Can't wait to get the motor in the plane and get her flying!

Nice chrome on the fuse, Kosh!

I'm finding it difficult to install the 2808 onto the wood stick mount in the Dandy. How much did you have to sand the mount to get the Himax to fit? I can get it to slide on (very roughly) for about 3/16"...that's not enough, correct?

You should be able to slide it so that it goes pretty much all the way back. I try and do that before the motor stick is installed. Much easier. But you can still do it after it is installed. I use emory boards that I stole, ( I mean borrowed) from my wife to sand it. Better to spend the extra time and get a smooth sliding fit.

Motor sticks..

A common error that should be addressed in the instructions,most guys just glue the laser cut pieces together before trying the fit of the gearbox,motor,etc.I always block sand the stick before glueing it into the fuse and try the fit of gearbox with several setups before I apply the glue.It can be sanded once its inside the fuse but a major PITA,use....I dunno...maybe your wifes nail file..??I think its also a good idea to glue a thin piece of scrap liteply inside the stick with thick CA,it gives the screw something more to bite into.

I prefer to have the motor stick assembled and glued together before it is fitted to the motor. I mark one end to be installed in the fuselage and sand the other to fit the motor mount or gearbox. many times it is too loose to fit snug into the fuselage bulkheads if the whole stick is sanded to fit the motor.

So I prefer to make a snug fit for the fuselage end. Then sand the other end to fit into the motor. Going for a nice slip fit (not loose) into the motor mount.

Great ideas...thanks, guys. I'll use the emery boards as you suggested. By the way, how do you affix the motor to the wood stick mount? I noticed that the holes for the screws are on the side of the mount, not on the top, where it is accessible...hmmm.

You will need to drill a new hole in the mount that is on the motor.

Ok...drilled the hole and finally got the motor to fit on the stick mount. I sanded with a Dremel for the bulk of it and then used emery boards for the final sand. It fits well, now.

[I posted this in my other http://www.rcgroups.com/forums/showthread.php?t=387933, so please excuse cross-postings. I want to make sure I get this problem solved...]

I must have done something wrong...the instructions say the following:

From step 20. "Glue the four motor mount sides together...Glue the motor mount to bulkheads F1 and F2 so that is projects forward 1.25" from F1."

The problem is the motor mount is only 1 9/16" to begin with. Therefore, there is no way that the motor mount can "project forward 1.25" from F1". Did any of the rest of you encounter this problem? I don't think my motor mount is long enough for this motor. I'm wondering if MM kitted me the wrong motor mount.

When I try to fit in the Himax 2808, it doesn't have enough of the stick to really mount to. If I push the motor back onto the stick sufficiently enough to get a screw in the mount, the outrunner can't turn because it is hitting against F1. I must have messed something up...

Help!
