Hi,
I am new to helis and have just purchased a R50V2 some time ago. Thru reading the forums, it seems to me that there are some minor issues with reliability on some points of the heli. So just wondering, what are the few upgrades that you guys will choose to put in this bird?
Dun ask me to go for a full bling bling head, the learning curve will kill all that sooner than i can afford!

I'm also having some stickiness with the carb but can't seem to iron it out even with several teardowns and cleaning. wondering if there's anyone running a push-pull system on the throttle? pics will be nice

metal frame posts -- make disassembling the frame easier and overall, stronger.

upgraded pins for the washout -- are secured better and less likely to fall out

The V2 head will not need any upgrades like the V1 series did. They fixed all the woofs and poofs and whas whas that plagued the v1 series.
the pins as stated above but other than that that is about it especialy FOR THE LEARNING CURVE. Best thing you can do is buy a crash kit right off the bat. have it ready cuase your gonna crash. WHat engine do you have? and what sickness are you having with the engine

Yup, picked up a set of crash kit and other bits that will break in a crash along with a pair of composite blades when i got the kit.
I have the stock TT50 in it, figured it'll be better economy for starting out and better fuel consumption?
the engine runs good just that the carb barrel is sticky now and then. got it jammed once and had to hold full negative on the ground to burn the fuel up. wouldn't want that to happen again. doesn't seem any good to clean the thing. I've just lightly sanded/polish is with 1000-1500 grit sandpaper, hopefully it'll solve the problems.
It runs on the rich side with plenty of smoke and lags a little on spooling up but i suppose that is due to the rich setting. smokes like no tomorrow! at hovering, the engine tends to rise steadily and settle to a pretty high/whinny rpm, is that due to the TT50 unmodified needle thingy?

i'm also having some constant swoosh swoosh sound at hover, wonder if that's due to the stock wood blades that i'm using. going to change to composite ones and give it a try. btw does anyone have experience with the FunKey 600mm composite blades?

definately get the washout pins, only a couple dollars and could save your heli. another thing to look at is the metal tail pitch slider. the metal slider, i don't think is really that important but it comes with the pins that use e-clips as well. don't want those pins coming out either!
that noise is probably just the wood blades but your headspeed could be a little low too.

I say the best reliability upgrade is the metal washout. The plastic wear too fast. It's quite expensive but well worth it.

a metal washout would be good. i am starting to see a little play in mine now. as for the pins, the part number is PV0115. they're about $2.50 and you can get them anywhere raptor parts are sold

1 metal washout base, I bought mine from helikraft ~$17

2 fuel filter, and one on the suction line of your fuel jug

3 3rd bearing between bearings for start shaft.

4 glue tape to tail boom to ensure tail box and frame mounts are very
tight

5 oil regularly the one way solid bearings each side of one way in main gear with light weight oil

6 tape xtal and servo connections into rx, rx mounted in soft foam,several choppers have died from this.
dont use ties to hold the foam tight as you'll negate the cushioning, I use rubber bannds-

7 tie power switch and tail servo to gyro connections so they cannot fall apart, see 6

8 only fit 4 metal frame joiners either side of main bearings and start shaft bearings, otherwise your adding surplus weight. I still run all plastic and i check im in the same start each time I start the self tapping screw.

9 the 2 nyloc nuts that retain the 4 grip bearings on the tail
file each to remove the slight radius on the non nylon end, this allows the nuts to pull up on the bearing inner race rather than the mount- this makes a big difference to the tail slop.

10 lube rubber dampers where the feathering spindle runs in them with rubber grease, this helps alot with the smooooth factor.

11 burn fuel lots and lots.


Regards Don

Hi Ammo,

Any news from the stuck carb barrel ? I just sanded mine too, and even after tedious sanding, turning and subsequent oiling it seems to be somewhat sticky.. Noticed though that it got a lot smoother, hope it stays that way... or is it asking for trouble ?

I'm using the 600mm Fun-key silver blades and i hafta say they are better than my NHP's i reckon. They're much quieter and auto really nice.
