Im looking forward to the V2 Rifle, with a better wing and less paint.
Has GP announced a V2 Rifle yet? I was going to pick up a second Rifle, but I think I want to hold off and wait for a few revisions.

i cant wait i just got an email from towers i'm gettin my rifle in next week i've got all the gear for it already i'm gonna try and keep it some what on the light side i am gonna stiffen the wing like said in previous posts and the wing tab fix

3S 1100 mah 45C hyperion lipo
ES55 servos
electrifly 25 amp speed control
24-40-3500Kv ammo motor (left over from GP L-39)
i'm gonna try 4.5 x 4.1 first and i got a couple 4.75 x 4.75 after i get used to the sensation of speed
all on a futaba 10C radio

i know no matter what the landing is gonna be long and shallow and quick but i was wondering if putting 2 servos in the wing and running it with flaperons would help to slow this slippery ship down but i gotta imagine that the roll control might go the crap but i might give it a shot i'll try in stock form first to see if i like it

flaperons always help on any quick plane but I dont know if it would be worth it on this slippery little bird. You most likely wouldnt notice a really big difference until there is so much travel set on the flaperons that controlling it would be rather difficult at those low speeds. This has always been my experience but I havent tried it with a rifle yet.

Sounds like something I will have to try with my slow stick first

Spoilerons (up ailerons) would work, but are only really effective on such a slippery model on a windy day. They'll do nothing for you in calm conditions. If you try this method be sure to mix in about 1-1.5mm of down elevator if your transmitter will allow. This will stop the model from ballooning up when they're deployed during the landing.

Ben, do you happen to know if these are available in the UK as I can't find them listed anywhere?
Thanks.

Ben D Wing you have that backwards. Spoilerons (ailerons up) cause a big dump not ballooning. Flaperons, ailerons down, cause ballooning. Spoilerons Up youll like need up elevator trim, Flaperons down youll need down elevator trim (too keep the plane flying level)

In my experience, spoilerons dont really work on speed 400 sized planes. You just end up landing a fast plane that drops like a stone. (ive pancaked a few into the strip while experimenting )

Flaperons do help, they dont add much in the way of drag but they do lower the stall speed allowing you fly slower, and land slower.

Im not talking big aileron throws, 5mm (MAX!)

I currently have 5 gliders and 1 motor glider in my hangar that employ the techique I described and none of them react like you say. There can be differences between models of course, but in my 41 years of active modelling I have not seen what you describe happen.

Spoilerons up dumps lift, the further they go up the more lift the dump (until they become drag) , in the same way you reflex a gliders wing to go faster (too a point) How would raising the TE create lift and cause ballooning?

ie. When you mix snap flap into a glider, Too pull a quick turn, TE of the wing goes down as you give up elevator input.

I agree though, there will be some difference between planforms, but ive never flown one that behaves 180 degrees different.

Or perhaps a tail hook deployed to catch the arresting line you've strung across the field !!

ps: don't use a bungee...most planes don't fly well backwards ... LOL

Edit: 136.50 I'd rather spend 13.50 more and get a proper pylon racer like the Sunracer!

Or spend just 24 on a Slipso 400 short kit and build your own. You'll get the satisfaction of creating something yourself and it will be a lot quicker than the Rifle equiped with a similar power train.
You can buy one here...www.Fine-Flight.com
