OS 120 is a good match for that plane with a APC16x6. Use epoxy everywhere you can on that plane my front end collapsed one time on landing, I had to re glued everything, not fun but no choice on this one, anyway almost all ARF need that.

There a video of the Velox with 16x6, not the greatest, but good enough for you to see the performance.

Hello Barry. I've been busy dealing with the troubles I described to you a long time ago and haven't flown much. I whacked my Velox about 6 months ago and I'm just getting around to the repair now. I got cocky with my CG and got it too far back. I ended up pancaking it and busting up the front a bit. It's very fixable I've just had other things to worry about. Things are calmer now so I've taken a few minutes to fly in the last week. It's been nice be back at the sticks. Do you still have your plane at the recommended CG or did you move it back a bit? It's been so long I'm not sure where I liked it best. I think I liked it with my battery behind the fuel tank but I know I flew it with the battery right behind the firewall the first time. It needs about 2 hours of work and it will be fine. Sometimes I think I fly planes better after I thump them once. It seems like I don't care as much and take more chances and fly better. Happy New Year and good flying.

Basement Troll....

Glad things are looking up a bit for you.

I fly mine with the CG right at 6". It seems to work real good there. It flys very nice and is just slightly tail heavy. It lands on all three wheels when you bring it in. But it's not hard, even in a stiff wind. I like the CG there. It'll do anything 3D and is just fun to fly there.

Hope you get yours back together soon.

Merry Christmas and Happy New Year.

Thanks
Barry

Thanks Barry. I'll put it at 6" and give it whirl. I'll likely get it finished tomorrow. It's not bad at all. My cowl is a bit rough now but most of the scars are on the bottom. If people notice that when I'm flying I'm doing enough tricks! Thanks again

ssimpson--- My 120 two stroke does a pretty fair job with this airplane. No regrets. At 9 lbs. 6 oz the APC 16x6 works well also.

I read some posts on shifting the landing gear of the Velox to the front to prevent nosing over. Can someone post some pics on how this is done? Are there any improvements done on the latest production models? Thanks

here is the plane with a Evolution 26 -dragging in a landing - the gear setup seems fine to me

Need wing tip LG? I just got Hitec 5625MG(100oz.+) for ail & rudd,2 HS635 for elev,and a HS5475 standard digi for throttle. Thats 4 digi's total,will a 2700Mah pack be necessary to get at least 4-5 flights? I'm only getting 4 with a similiar set-up in my X100,seems kind of low for that size pack(all 6V).

Gungadin

mixmaster--I have 4 Futaba digitals on mine and I get at least 7 flights on a 1700 mah pack.

rmh

Wing tip never touched -the model was flying not falling
Use a good low imedance NIMH - 1500 is enough if you get a modern pack -use 6V

Well I've got it back tobgether and ready to fly. It's a bit heavier now though. 9lbs, 3oz. Thats about 4 oz heavier than before. I guess that's what happens when you do dumb things. I'll wait for a nice day to try it again. It deserves a fair chance.

Well the Velox made it through its re-maiden. I flew it twice and all went well. This plane does anything I can do very well. (That's not necessarly much) I do struggle to hover with it though. I might move the C/G back just a bit and try again. YS 110 is lots for this plane. Nice to see it in the air again.

I buy only Sanyo cells from various vendors like Maxx Products,Cermark. My last few purchases were dissapointing as far as run time,I remember getting much more time with lower capacity packs, dont know whats going on here. I am using more digitals and more torque than before but I buy more amperage to offset the extra draw,not getting me more time,less actually?

Gungadin

Mixmaster--That does not sound right. Maybe your charger is not fully charging your packs. I use a 6 volt 1700 mah sanyo nicad pack that I got from Maxx Products and I get at least 7 or 8 flights from it. I have a total of six Futaba servo's , with 4 being digital. Maybe you have binding somewhere that is drawing lots of current or your pack isn't getting fully charged by your charger. Hope you find the problem.

I use various chargers with the same results,mostly overnight chargers(125 to 150mah)that I leave on for around 20hrs. I also use field chargers with 500mah (C/2) max ,doesnt matter,still only getting 2-3 flights with several different planes. I never quick charge Nimh with more than 500mah,usually use 300-400mah,which should not heat them up at all.The only flying habit that has changed is rolling harriers,I just started doing them this year(2006) and I use spoileron mix so all servos are working all the time and the aileron servos are moving a whole bunch. Still not sure why the decrease in performance,specially since I went up to 2700Mah in the X100 and Giles and still only 3 flights max. I never fly the packs below 5.9 V,I'll start a flight at 6V, but thats it. I have noticed that when I test a pack at home,it takes an hour @ 1000Mah drain to get the pack to drop from 5.8V to 5.7,a whole hour for just .1 V drop and I think that 5.8-5.7V is within the operating range of the reciever but dont want to push it. That would be several flights right there but I dont trust it that low.

wildnloose

That's pretty high, considering you could safely drain them to 4.5v (which is well above the rcvr cutoff voltage). But, having lost 3 planes to low batteries, I understand why you are being safe...

Have you cycled your batteries to see what the capacity is???

MIXMASTER

My Feedback: (15)

Its not the reciever cut off voltage that I'm concerned about when using 6V,its the voltage/per cell. I dont think its good for the cells to run them down below 1.1V/cell,at least I never had to before to get 4-6 flights. Now that I think about it,when using the cycler,it puts 1000mah load on and runs for hours from 6V to the minimum discharge(around 5V I think),which is 1V/cell. If I could safely operate in that range I would but again, I never had to before. Hold on,I just remembered that my Hobbico charger AND tester both just crapped out a few months ago,maybe the tester was giving me false readings,that would account for the change in battery performance. Back to running below 6V,does anyone fly below this?(using 6V of course)

wildnloose

I do all the time. A 6v (5 cell) batt fully charged is about 1.4v/cell. Nominal voltage is 1.2v/cell. Discharged voltage is 0.9v/cell. I usually stop around 4.8 volts.

What concerns me is that your initial charged voltage should be higher, closer to 7v...

Wow!.....

They are selling this plane now for $179.00!!!!!

That is a bargain on a wonderful flying airplane.

thanks

I fully charged a couple packs,one old and one new, then I monitored the discharge curve of both,interesting that Nimh do seem to have a "cliff" in the curve where they drop off suddenly. I though only Nicad did that. They drop fairly quick from 7V to 6V,then hang around longer from 6V down to 5.8,then they start to quickly drop faster with every .1V drop. I only got about 15-20 minutes from 5.6V to the "end".(4.7 I think it was) If I started a flight at anything less than 5.8, it could be the end of my plane. This is with a new(forming charge was done previously)pack and an older one,both had the same characteristics. Some where in this forum people are stating that its OK to fly a 6V pack down to 4.8, I dont think so!!!!!

wildnloose

If this is a loaded voltage reading then its perfectly fine. At this point you will have plenty in reserve. If this is rested voltage then you need to recharge(because loaded voltage is probably below 4.5v, which will kill the battery pack)...

MIXMASTER

My Feedback: (15)

Loaded,no-load,doesnt make much difference to me,its how quickly in "time" it drops. I know the receiver can function a little below 4.8V and the servos too, but my 5 cell Nimh packs drop rapidly once below 5.6V,I mean one flight could be it. It drops all the way down to below 4.8 in 15 to 20 minutes,one flight for me. Once at that point, you are further draining the batteries,risking the battery life and more important-plane life. I've flown once when down to 5.9,I know it takes a good 20 minutes to get down to 5.7 or 5.8,but after that, you are dangerously close to that "cliff".( I always use a "loaded" meter) Imagine a stuck throttle-not too hard to envision,has happened to me and several others here at my club.

I understand, and I digress...getting back on subject.

Sounds to me like this discussion now belongs in the batteries & charger forum.
