Any one built or flown a Laser Arrow? I am currently building one and would like to know what performance i can expect with a 46FX. The model is approved for a 61, however i think the 46 should do the trick! Also any info on the CG with this engine or similar would be cool!

I have one and love this plane, I am running a Rossi 45 with an APC 9x8 and a short pipe. This plane is very fast and stable. Set your expo up so you have some throw to flair for a landing when in slow flight but it is manageable at HIGH speeds. It flies like it is on rails and lands on the skid with no problems. If you look back a ways or do a search you will find another thread on this plane that I started. The CG on mine is set up like the plans said with no trouble, I used an 1100 MA battery to help with balance. Jeff

Thanks for your reply, how did your CG come out? seems like every one had to use a bigger battery of add weight to the back. I saw one guy used a 1100mah batter to compansate -did you add anything to the rear of the plane? sis you set it up with elevons or as a standard config -no mixinng?

I put my battery back at the back and I think I added a little lead to the opposite side as the pipe in the back corner to off set the weight of the pipe and balance it from left to right as well as front to back.

I changed engines from a Jett .40 w a APC9x7 to a Picco .60 swinging a 9x10 APC. I've peeled off decals in a power dive. Major speed...Great plane.

Glen, you have me thinking now, I think I will build another this winter and stick a Rossi .60 with a pipe on it. Just happen to have one laying around. I like the peal factor you mentioned!

Flipper; I just had to try it..U know , I loved it w/ the Jett.40, The Picco.60 I bought here from the engines for sale ads. NIB for 100.00 bones. nice engine. With the thicker airfoil , weight don't mean anything. For how fast the jett was w/ an APC 9x7, and having a few APC 9x10's;... wanted to try spinning even more pitch. Well I'm not disapointed. Hell fire on nitro diet...I like it";...LOL. .I also have a Ripmax Rapier arf, I bought from Tower @ 119.00 this past month or so. Very close to the Lazer Arrow, built the same way, has more of a fuselage, a little bigger than the lazer, cause of the fuselage. wings are the same. I haven't flown it as of yet. The Rapier is nice and I'm putting a MVVS .49w/ mini pipe in it. Question: on your lazer arrow, did you put a handle on the top side above the skid CG., area to make launching easyier ?
That's what I did,best thing I added on the arrow...Glenn

I've been eyeing this model at the LHS for a while. The only thing holding me back is launching it. Is hand launch the only option?

Yogi... how did u power it?

It's real easy to do by myself, but you could have someone else let it go for you, not much of a launch required. There is no landing gear, just a 1/4 thick plywood skid that has worked fine for me as a handle and landing skid.

Hey Flipper, Howard is putting me one together as we speak, going with a Webra speed 50 and tuned pipe for now. Maybe increase engine size after I get used to it.

Flipper-

So u just hold it from the skid and push? As long as it's a one handed launch I'm OK. Not many folks I can trust to hand launch for me at my club. I've lost a plane or two like that.

Thanks
Mum

Yes, I just hold it up and open the throttle with my mouth and let it go. No need for a run and launch.

Default Hey flipper qsdriver again

Man all you guys are starting to depress me, ive got a 46FX im sticking on mine- after listening to you all sounds like I should of went with a .61 Maybe I will have to build another one also.
QUESTION -Do you guys think it matters if you put you engine mounting bolts in so that the lock nuts are on top of the engine flanges? Why do people do it this way as oposed to normal -with the lock nuts under the mount? I am covering my Arrow now -flight this next week hopefully!!!!

qsdriver,have fun on your test flite...with the .46 use a 9x7 apc

qsdriver, I don't see why it would make any difference on your locknuts. I always use socket head screws and you could still get the allen wrench on them from the bottom with the pipe on. Make sure you paint your front end, firewall and tank compartment with some epoxy to add some strength. Have fun and let us know how it flies!
