HL upgrade gearbox
Posted: Tue Dec 20, 2016 6:49 pm
Hi All
After some advice please, I have done a forum search and have not found much joy on answers, so excuse me if it's a common question
I've just stripped my M41 Bulldog, and seen the plastic gears are stripped, the smaller one connecting to the drive sprocket shaft (if that's the correct term for it). I've looked at various sites to purchase a replacement gearbox, but am getting a bit confused as to what I need.
Prices range from £9.00 for plastic geared boxes to £70 for metal geared boxes.
With the metal ones which is what I want to upgrade to is where the questions come in:
pot metal - cheapest
Brass - more expensive
Steel - most expensive
Q1 - There are also many different brands, so which ones are better/best?
Also I assume, as with my helicopters, once you upgrade to a metal part something else has to give to the stresses, now I appreciate the tanks motors are not spinning at ridiculously fast rpm's, but I suppose the same concept applies here.
Q2. What other recommended upgrades should I do to avert breakages with a metal gearbox upgrade, is the plastic chassis a concern?
Q3. gear ratios, I've seen 3:1, 4:1, 5:1 - 5:1 I would assume gives more torque/pulling power and less speed? which is better for less stress throughout?
For the Bulldog, I think I will have to resign to the fact it will just be a general play around for myself and my son, due to lack of upgrade parts for it, so not too bothered on realism etc.. that will go in to my Panzer.
look forward to your helpful replies
cheers
Andy
