VIP Racer (Was: What Pylon Racer to get?)


I ordered a FVK Boomerang pylon racer from Soaring USA last night, it will be my second racer, after a Sokol. For those of you who have built one, what servos would be good, I'm a bit leary of using HS-55s in such a fast plane, but that also seems to be the most often used servo. Next, is Spektrum usable in the model, preferable a 6100, or I can toss a Berg 4l in there, if there is too much CF. Third, I'm looking to push this one about to 100, maybe 90 propped down, and up to 120 with a bigger prop, what motors would be good? Last, any tips/suggestions for the build?

*******Soaring USA was out of Boomerangs, I'm looking for a different model, preferable below $200, and ~30" span, fully molded would be nice too. Sport flying only.

I have a Boomerang and a VIP and both are very nice models. Space in the Boomerang is very tight indeed and unless you use a very slim aileron servo you will not squeeze a 3s lipo of reasonable capacity to support the current draw in there. I use a HS55 in my VIP and have done for 3 years with no problems at all - amazing performance really. Whilst I can comfortably get a TP PL 2100 3s in the VIP I can only get a 2s in the Boomerang. I am currently running mine on a Hacker B20 12L and 4.1x4.1 prop but it could do with more power. Still, it is probably good for 90-100 mph. The VIP I estimate at about 120 on 3s power and Hacker B20 15L.

I will be interested to hear how you get on, and any other input you get.

Oh, and watch out for aileron flutter - I had to use some silicon adhesive spread very carefully along the top hinge to cure mine, and there was no play at all in the linkages.

Well, I just got a call from SUSA, they are out of the Boomerang, and won't have any in for 3-4 weeks. Any suggestions for a good replacement? I'd prefer a cost <$200, and about a 30", all-molded plane. Thanks. (I'm looking at the Sprint, the Quick, Adrenaline, or Stinger)

Are you sure that you want a 30" plane? After flying a bunch of 30-inch pocket rockets, I am now moving into f5d with the Sunracer. It is a nice, straight flying model, large enough so that you can actually see it. It is a little more than you want to spend, but it is really worth it.

I have crashed it now 3 times, and was able to fix it every time. The first crash was radio failure, the second was due to flying too late into the sunset, and the last was due to landing in a tree. I had another spectacular crash this weekend when I had a wing servo pop off. Plane is otherwise fine, since the fuse has so many layers of fiberglass after repairs that I can lawn dart it without damage! I also use nylon wing bolts- a real lifesaver compared to metal pins in other models.

If you don't want to spend the extra $70, you might also consider the Hummer. Mine was insane, and flew quite nicely if you could get past the torque roll on launch.

I really liked my sokol. Lots of room for gear and flys nice.

I like mine too, but it's in need of replacement, and I'd like something new.

I should have read your first post better. FWIW, in the S400 size, I've also got a Quick and Triffik but like the sokol the best. Oh and I just today got a Hummer . It appears to be very well put together but I haven't flown it yet.

Nice looking plane, real hippy/flower power colours!
A good power unit would be a Mega 16/15/3 on a 3s LiPo turning an APC 4.75"x4.75", 'Ballistic flight' is a phrase that comes to mind!
These motors aren't too expensive and can be pushed nearer to 35Amps (with adequate cooling) than the 30A recommended in the manual.

How does this motor NEU-1105-2.5 compare with the Mega 16/15/3 for a pylon racer like the Stinger?

I have the NEU already, but I will get the Mega instead if its a better setup.

Stick with the Neu motor seeing as you already have it, as IMHO it is the better (if more expensive!) of the two, but if I had to buy from new then my personal choice would be the Mega as I don't have too many $$$'s spare! .
My Mega 16/15/3 is currently in a Simprop 'Turn Left' which makes a great compact Hotliner.

Very nice model, though not as strong as a VIP. I will be interested to hear how you get on with battery selection - let us know
