For immediate release:
**GREAT PLANES REVOLVER .46-.70 EP ARF
A sleek aerobat with hybrid versatility! It’s the “sports car” of sport aerobats! The Revolver’s contemporary styling makes it a real standout on the flight line. Once it’s airborne, it really takes center stage regardless of whether it’s equipped with a glow engine or brushless motor. Pilotswith low-wing experience will feel right at home putting the Revolver through its paces. On-board radio gear is quickly accessed through the hatch. It also makes it easy to change LiPo battery packs when equipped with an ElectriFly™ brushless power system. The bolt pattern on the firewall lines up exactly for either a .46-.70 glow engine mount or a motor mount for installing a brushless out-runner motor – such as the ElectriFly™ RimFire™
(GPMG4725). And the Revolver is expertly covered with MonoKote®!
• Select balsa and ply are used for the fuselage and tail section; the 2-piece, plug-in
wing features a wire cut foam core that is balsa-sheeted.
• Airfoil-shaped tail surfaces allow the plane to lock in and track solidly.
• Short and direct aileron linkages deliver strong, accurate control during high- and low-speed flight.
• Comes with a complete package of quality Great Planes hardware including a polished aluminum spinner, vacu-formed canopy and pilot figure.

Did you have any trouble balancing this model? It's VERY tipsy and I cant seem to find the right balance. Sometimes it falls forward, other times it falls back. I'm using the great planes balancer and I've never had this issue before.

Copied off the RCU review. Check your CG.

http://www.rcuniverse.com/magazine/article_display.cfm?article_id=922

The CG was not set per the instruction manual, my manual is incorrect and it says the CG should be 4 15/16" back from the leading edge at the root. The CORRECT CG is 4 5/16" back from the leading edge at the root. My model balanced perfectly right on the correct CG with the packs in place. I have been told this was a typo and the current production kits should have the correct CG in the manual

Research on the Electric version:

Stock weight with 6S 3200 batteries plus Rimfire 42-60-800 = 808g or 28.5oz

Weight with AXI 4120/14 motor and 5S 5000mAh TrueRC 10S back = 905g or 31.93oz


I've already added 1oz to the tail in order to help with the balance, but due to the models battery location, it's difficult to do anything more than add additional weight. Will this cause issues in flight?

Where do you have your receiver battery? Though the manual shows it under the servos for the electric version I ended up putting it on the the firewall mount to balance the airplane.

I don't have a receiver battery as I'm running a BEC setup. The plane seems balanced now after a little guidance from kevin. I removed all of the washers I had originally installed behind the pilot. My configuration, as stated above, is 3.4oz heavier in the front end than stock, so I added 1oz of lead weight to the tail and it appears to be perfectly balanced now. As this is a mid wing plane, it's harder to get an accurate test vs. the low or high wing models. Also, what does hook and loop method mean for testing? Is there a better way to balance the revolver other than inverted and using a Great Planes balancer?

Heads Up

I totaled my Revolver today. The left aileron box came out of the wing during a snap roll. Really ticked me off as I really like flying the aircraft. Not sure how you can check yours but I think if I get another I will drill some holes in the boxes and insert some 1/8 inch wood tooth picks and some foam safe glue.

Dang, not good!
I snap roll mine at break-neck speeds. Now I will start worrying
