Graupner Monsun Build - Run down on electronics?
Getting ready to pull the trigger again on the Graupner Monsun.
I am saving money with parts already in-hand and purchasing others for lower cost than Hobby-Lobby (HL) has "packaged" with the Monsun sale page.
Here is their page:
My list so far. Please comment freely and let me know what is goo, bad, and what you would change if anything.
#1) (1) HiTech (HT) Feather Reciever (6.7g)
#2) (1) Great Planes (GP) C-20 ESC (17g, 22A)
#3) (3) Futaba S3106 Servo (9.6g)
#4) (1) HL (GR170523) 400 Speed / Geardrive 2.33:1
#5) (1) HL (GPS09060) 9x6 prop
#6) (1) HL (GR1298) 30 mm Spinner (4mm shaft)
#1 Is the feeather too light? I mean, should I step up to like the HT 555? It has better listed range, and an extra channel. Is the feeather okay here?
#3 Are the servos okay? I can get them at a good price comparitivly so I thought I would go with them. The weight, torque and speed look okay as well?
#4-#6 I could not find these parts much cheaper, so I thought I would just go with what they have on their sale page. I downloaded the manual for the Monsun and it shows a speed 600 configuration? Is anyone doing this, or is speed 400 more than enough?
# What about the prop/gear setup? Any problems or suggestions?
Thanks for all, and let me know if you have any comments.

The only thing that I would check carefully is the Rx. Personally I don't think that the feather has enough range for this plane. I would probably switch to a 555.
I am not sure what you downloaded re: instructions for a Monsun, but Graupner used to have a larger Monsun kit that was for glow or could be converted to electric. This larger model might have been appropriate for a geared 600. The new ARF Monsun is only suitable for geared 400 or 400 brushless sized motors. The weight of a larger motor would be far too much.
Check and thanks for the advise:
o Going with suggested 400/gearing
o Switching to HT-555 receiver
o After reading more, I am also going with suggested Jeti ESC
### New question:
What battery can I go with? In my experience a NiMH is better. How many cells? Suggested is 8, but I have seen 10 discussed here. How many Mah should I be looking for?
Thanks agian for all,
