Default PQHOR and .25FX

I'm going to be building a PQHOR and want to get some feedback for engine selection.

I have a .25FX coming out of a PBF. It can hover the PBF. Will this engine be enough to hover the PQHOR?

I have an Irvine .53 as another alternative but think that may be too big? Any thoughts?

I have one with a 25fx. Will climb slowly vertically and hovers fine but keep it as light as you can. I think the weight of the profile fuse would put it over the limit. Mine is 32 in span but i think 30 in would fly better at a little lighter weight. Lifts of in 10 to 15 ft with no wind.

Default 25 PQHOR

Mine has a Thunder Tiger 25 with a mouse can muffler and it hovers great at 3/4 throtle on a 9x4 master airscrew.
Cant seem to kill the thing. Flat spun the thing on purpose 3 times all the way to the ground , could not stop laughing in time to pull out, no damage but great fun and impressive. Falls like a 3 hole brick when dead stick

Thanks guys.

I think I'll build it and fly with the 25 FX and see how it does hovering.

Worst case I'll throw the 53 in it.

Build the .40 size qhor and put your .53 in it, you will be much happier, check out my prop site below for the .40 size one with a .75 in it.

You will be margionally powered IMO with the .25

I'm building a .40 size now for a .46FX, but I've got an OS .48 4cy layin' around. Do you it'll be OK for the .25 sized PQHOR?

Thanks John, I read the thread where you put a .75 on your PQHOR and the pics tell the whole story. I'm always overpowered. I like it that way! But I also saw the video that you posted for Jason ( :thumbup: CHOICE!) and read that he was using an OS.46 and I reall like the way his flies.

Now, I've got an MVVS.77 and an OS.46 FX. I plan on building several PQHORS, but I want to start off w/ a good set-up for my first one. Which engine should I use first?

Oh, also, have you built a SPA3D? Do you think it flies better than the PQHOR?

I flew my Spa3d for the first time today. Same plane and engine as the one in my video, just a new wing. I love the way it flys. I did several toilet bowl flat spin landings. It still t-rolls and hovers/harriers the same as the old one. Spins and snaps are also much better.

haha, I have had the mustand since RCU started up. And I will go back to it eventually, love my race car!!

But I am having so much fun with the sukhoi I couldnt help it, that pic was perfect!!

I dont have any coro in it, but I have a piece of plastic holding the whip antennae in it, does that count?

Here, check out this thread for some sweet pics and a vid:

I will probably go to one high torque servo in the channel for the ailerons. I saw one at the last fun fly I went to and it had a much better roll rate than mine. He also had much more authority with it in rolling harriers. He was doing slow rolling harriers on the deck. It was awesome. I think putting the servos in the wing causes the wing to flex under load and kind of works against itself giving a poor roll rate. We'll see anyway and I'll post my results sometime in the next week or two. I'm in the middle of packing for a move. I moved my whole hobby room today (so sad). Got get settled a little before I can go flying again.
