I am starting a gasser build on an R90 heli. I've been looking thru the "archives" to figure out what tricks and upgrades to do the R90. For example, on a 30 size, there is a need for heat shring on the tail gear pin and drill a hole in the tail case to view the pin. Any recomended modifications/replacements for the 90? It will be an SE version.

My R90's have been the workforce of my fleet. They are tanks...and rightly so if you throw one on a scale! haha

Misc items in no particular order:

1. Heatshrink on tail bevel gear to keep pin secure. If you do this you can skip drilling a hole in the case.

2. Recommend upgrading the OWB unit to QuickUK. It will NEVER lock up on you.

3. With the extra weight of the gasser - you may want stiffer head damping. I like the solid delrin style which uses o-rings for damping best.

4. I changed out the stock R90 550cc fuel tank with the smaller R60 tank since I don't need as much gas compared to nitro.

5. If you go RC style over PUH, QuickUK landing gear are easily adaptable and offer more height to clear the RC style pull start.

6. Go with a large Mah flight pack or on-board generator route to compensate for longer flight times if desired.

I'm sure there are others.....I'll post if I think of more.

Good luck!

Thanks for the info.

What OWB unit is recommended by Quick UK? I was also thinking of upgrading the tail gear box to an aluminum one by elevated rc.

I am planning on putting in a 12OZ Sullivan fuel tank in the nose.

I am going with the RC style motor; G240RC. However, I will be top starting it so I will be replacing the pull start with an ADA air scoop.

I'm probably going to use a 4.8V NIMH flight pack out of a titan SE I will be moving the electronics over to the R90.

Also, as for ball links, I am looking for a good set of links to upgrade to over the raptor links. Are they the same links as the R30/50 and any recommendation on ones to upgrade to? I've read century has some good links.

Absolutely nothing wrong with stock TT links.

OWB - One Way Bearing. The stock TT unit had a tendency to lock up while the QuickUK used a better and larger bearing arrangement which, to my knowledge, has never locked up on anyone.

You can use the 4.8v NiMh, but you will be loading those flight servos pretty good on a R90 sized frame loaded with a heavy Zenoah motor. I would consider upgrading to LiPo or Li-Ion. My 2c

Quick UK or FMP ball links. What about the G4 tail case?

Neither - stock Thunder Tiger links are perfectly fine. There has never been an issue with the links. Install them logo side out.

G4 Tail sure is pretty, but, not a necessary upgrade. If you have the spare cash, go for it - otherwise the stock R90 tail assy is quite good.

What about the G4 tail case?
I considered this, based on a thread i found from navyraptor i believe and it sounded like it went back and forth on what to change even to the point the tail driveshaft may need changed so quite honestly I got confused. If you have any info on doing this, that would be great!

As for my electronics, . I am planning on use a GY401 gyro, a R617FS receiver, a futaba 3010 on the rudder, all other servo's will be futabe 3152. See any issues wih these servo's? Maybe i should use a 6v flight pack as opposed to the 4.8v, i'll give that some thought.

I have an airframe on the way that has the Elevated rc tailcase and the upgraded OWB. Sounds like the previous owner took great pride in the build. Now just need to figure out if the servos i have will work.
