Mods for SAL?

Stock bug can be SAL with a preset on your transmitter to compensate for the yaw of a SAL. If you're right-handed put in 3-6 'clicks' of right trim and maybe a few up trim - start off easy and work up to full power adjusting the trims as you go. Most who SAL the bug carry the CF tube past the outter rib to the edge of the wingtip, then sand it to a taper. A touch of fiberglass cloth on the launching wingtip wouldn't hurt either. Say .75 oz - 2 oz. weight. A small patch of glass to join the V-tails wouldn't hurt. Say on the topside of one side, over the CF tube then up the other side. The V-tail is going to take some rotational stresses at launch so a little reinforcement is in order. Keep it light - 2 oz. cloth max. HS-50 servos are great. I'd go with at least the 150 mAh NiMh pack, I used a 280mAh pack myself, and made up for the extra weight by switching to a GWS R-4P receiver. If you're a dual-conversion must-have person then go for the FMA M-5 instead. If you really have to use the 555, at least remove the case and use some light clear heat-shrink on it. I like the 'clearly superior' stuff sold at ihttp://www.airdyn.com (formely nyblimp.com). Personally at $28 the GWS receiver is my personal favorite for the Bug. The bug is a blast, no matter how you launch. Careful, it's addicting! You'll be up to one of the $400 composite ships in no time. Al > > A friend just told me about this group.

If you add the extra rib, you might want to consider going to a S3021 airfoil - it's thinner than the S3014 that the bug currently uses so you'll get better penetration on launch which is what SAL gliders want. Only do this if you extend the wing though as S3021 needs more area to get the lift you need. Also, if you're looking for the next step up for SAL, you might consider "The Gambler" from my site: http://www.wrightbrothersrc.com I have a new batch of laser parts due any day and will have more kits available very soon.

Your servo, battery, and radio setup should work, but I had to add quite a bit of weight to balance it out. You might want to add a fourth nicad since you need the weight up there anyway. For sal, the best mod would be a cruciform tail. With it, my bug tracks arrow-straight from launch. The penalty is a bit of reduced performance that is particularly noticeable when your fight turbulence close to the ground. I found the V-tail allowed the bug to "wobble" a lot on launch, and hard launches would actually snap roll it. I have a picture of the cruciform tail (Colin's idea) in the Photos section in the folder named Paul Johnson. For covering use nothing heavier than light transparent ultracote. For your next bug, check out Colin Bosch's ideas, his photos are in the Photos section in the folder named Carbon Bug. Good luck, and watch out for hawks. -PJ ----- Original Message ----- From: balsabreath <alclark@...> To: BugHLG@yahoogroups.com Sent: Monday, March 03, 2003 6:21 PM Subject: [BugHLG] Mods for SAL?

I have been flying "The Bug" for about a year. It will SAL fine and all I have done is add a .056 layer of fiberglass with CA to the wing tip for strength. I have also sprayed the fuse with 3M77 and added the .056 FG to it with CA. It helped because I was learning and had some hard landings. The CA and FG do not add much weight. You should build a second wing with an extra #3 rib on both sides. That extra rib adds a lot of area and not much weight. It will make it a little less responsive but it will float even better. --- In BugHLG@yahoogroups.com, "balsabreath <alclark@k...>" <alclark@k...> wrote: > A friend just told me about this group.

A friend just told me about this group. I have just completed building a stock Bug from the RCM plan and am ready to cover. Can the Bug be side arm launched? Are modifications needed to do SAL? If so, what are they? I plan to use a Hitec 555 Rx and HS-50 servos with a 50 mah 3 cell NiCAD battery (or 150 mah 3 cell NiMH battery).
